The Paradigm Shift in Enterprise Emergency Services

More than 50 years ago – in the small rural town of Haleyville, Alabama – history was made as the local Haleyville Telephone Company beat the giant telco conglomerate AT&T to the punch on February 16, 1968 when the very first 9-1-1 call was placed at 2:00 pm. Today, the very phone used to answer that historic call from State Rep. Rankin Fite and answered by U.S. Rep. Tom Bevill at the Haleyville police station is proudly housed and on display at the new National Law Enforcement Museum in Washington, DC for all to see as a part of Public Safety history.

NENA, the National Emergency Number Association, estimates that more than 240,000,000 times a year in the US, citizens call 9-1-1. That’s more than 7 calls each second. But, even today, potential problems can still exist. One of those issues is Direct Access to 9-1-1 from multi-line telephone systems installed in many schools, hospitals and commercial businesses. In many cases, these systems require an ‘access code’ to be dialed before any external phone number, including 9-1-1. While this is most commonly a ‘9’, it can be a 7, or an 8 or any other combination of digits.

When we go through the lengths that we do to teach children about 9-1-1, this important fact is rarely, if ever, brought up.  Kari Hunt’s 9-year old daughter Brianna found that out on December 1st, 2013 as her mother was being brutally attacked in a Marshall Texas hotel room and ultimately was murdered by her estranged husband. While Brianna knew exactly what to do, and in fact tried 4 separate times, because the MLTS system was not programmed to recognize 9-1-1 without the access code of 9, the calls went nowhere.

Four years, two months, and 15 days after that dreadful day, with the help of several folks in the industry, including Avaya, the President of the United States signed Kari’s Law into the law of the land on February 16, 2018 just before 2:00pm, nearly 50 years to the minute after that momentous, 1st 9-1-1 call in the rural northern Alabama town of Haleyville. The moment that ink was dry on that document, a 2-year clock started counting down to the effective date of February 16, 2020 when the law would go into effect for all. Just. Few short weeks after that event, the Ray Baum’s Act was also passed by Congress, and in Section 506, the FCC was required to complete a proceeding that would address dispatchable location requirements by the fall of this year.  

This past Thursday, August 1, the Federal Communications Commission concluded it’s required action at it’s Open Meeting, where I had the honor and privilege of attending this meeting in person with Hank Hunt.  Later that afternoon,  we were invited to join FCC Chairman Ajit Pai for a Podcast celebrating the event. (Listen to the Podcast here on the Avaya Podcast Network)

During the Podcast, we discussed the fact that, often, the problem of direct access to 9-1-1 is a simple one that can be easily addressed in most systems sold today. In fact, many systems sold over the last decade have this capability available and inherent in the system. Often, it is an unknown feature that is rarely activated, despite the cost point being ZERO. This was a point that I presented to the FCC when I first brought this problem to then-Commissioner Pai, when I first met with him on January 10, 2014.

It was at that meeting where the commissioner was first introduced to this problem, and the tragic story of Hank’s daughter Kari, six weeks or earlier. Soon after hearing about the issue, FCC commissioner Michael O’Reilly decided to check the FCC’s very own multi line telephone system, and quickly found that dialing 9-1-1 did not reach 9-1-1, but resulted in the message, “Your call cannot be competed as dialed, please check the number and dial again, or call your operator for assistance”. Calling out his own agency for non-compliance in his FCC blog dated June 2, 2014, was slightly embarrassing, but accentuated a point:

AWARENESS WAS NEEDED AT ALL LEVELS

Another sensitive area regarding legislation was penalties for non-compliance, as well as the financial impactof those penalties that are applicable. In any legislation, the financial impact is a taboo topic that is rarely discussed. While I had our Communications Commander-in-Chief in my grasp on a Podcast, I took advantage of the situation and probed for his opinion on this elusive topic.

“Mr. Chairman,” I asked, “does the FCC have the ability to impose a penalty?”

I held my breath, waited for the stinging sensation of taser needles hitting my back, and the sound of handcuffs being clinched around my wrists, but instead, the Chairman responded with, “Of course I need to confirm with our lawyers, but I believe we do . . . [T]he FCC does have the authority to issue fines; to go after people who don’t live up to their obligations; and we have an enforcement bureau here […] that is always willing and ready to stand up and make sure that our rules get enforced.”

That statement signaled a ‘we mean business in this issue’ and was one if the strongest statements I have heard from the Commission on the topic. The Chairman concluded with, “[I]f you’re an MLTS provider that’s not living up to the requirements of Kari’s Law, we are going to make sure that you’re held to account.”

That being said, as for the actual collection of any penalties assessed, that was an area where the Chairman admitted that gaps still exist and had been identified to Congress. While the Federal Communications Commission has the authority to enforce their rules and issue fines for certain violations, should an individual choose not to pay, the FCC’s only recourse is to solicit the Department of Justice and request that they file a lawsuit for the actual collection of the fine. Clearly not ideal with all of the other initiatives DOJ has on its plate, but none-the-less, a process exists for recourse, and if you make the DOJ mad at you, you are walking into the lion’s den wearing a pork chop body suit.

While over the past years, Enterprise administrators could take the low road, and claim ignorance on the issue of direct access to 9-1-1, on site notification that provides actionable information to 1st responders, and a ban on intercepting and answering calls internally. But Kari’s Law has brought about awareness. It shined a spotlight on the issue that almost anyone can see. While the personal cost of this enlightenment was the loss of a precious life, something most of us will never truly understand, what this incident also did was ensure that Kari’s memory will remain as a testimony of her goodness, and the ultimate sacrifice that she gave so that others would be saved. And most of all, Hank’s one and only wish was fulfilled, that Kari’s death was not in vain.

July 4th | 9‑1‑1 | Fireworks – A Perilous Combo?

Back in 1980, when I was a police dispatcher in Sparta New Jersey, I can remember that inevitably every year on July 4th at about 8:00 PM, nearly every line on the phone would light up. For the most part, the conversation would go something like this:

Me:      “Sparta Police, dispatch”
Caller:  “Uhhm . . . yeah . . .  Can you tell me what time the fireworks start?”
Me:      “Same as last year sir, at dusk, usually right around 9:00PM”
Caller:  “OK . . . Thanks”

Not every call asked this, there were some interspersed inquiries:

Me:      “Sparta Police, dispatch”
Caller:  “Uhhm . . . yeah . . .  Can you tell me where I can WATCH the fireworks?”
Me:      “Probably in the sky . . . ”
[OK, so maybe my snarky attitude wanted to say this, but of course I remained professional]

The SAME call scenario then repeated for nearly the next hour, over and over and over. Much of the time, every available line would be lit, and every caller had the same question. In a way, it was almost comical.  The residents of these 3 tiny municipalities, a total population of 30,000, were under my care, but I was unable to help them in an emergency as I was tied up answering these calls. There I sat, all by myself, hoping and praying that no one was experiencing a REAL emergency and needed a real response for help. In an effort to break up the monotony, at times, I answered the phone with:

Me:      “Sparta Police, dispatch . . . the fireworks start at dusk”z
There was usually a long silence and they would respond, slightly confused
Caller:  “Uhhm . . . Thank you?”

Eventually, just as this rash of calls started to diminish, the next wave started to come in:

Me:      “Sparta Police, dispatch”
Caller:  “OK, hi . . . so . . .  there are a bunch of kids with fireworks over on East Shore Trail”
Me:      “Ok, can you tell me what any of them are wearing or which way they are heading?”
Caller:  “Nope, but they are raising hell over here and I am trying to sleep”

But that was 40 years ago, and times were very different. The communications technology was in its infancy, and everything was written down on punch cards, and time-stamped on a time clock (ka-chunk, ka-chunk). There was no 9‑1‑1 in my center, just POTS lines on a 1A2 Key system. Heck, while 9-1-1 may have existed somewhere in NJ back then, I didn’t know of anyone in the State that had it; and as for caller ID? Yeah, right! Ha ha ha! That was still a far-off fantasy. Back then, we worked under the bare minimums. Today, with four decades of techno-babble under my belt, quite a bit of self-taught programming in BASIC, QuickBasic+ and a little bit of C+, my favorite new word has become ‘workflow’ or scripting. At the core, a program is based on a flow chart. A list of actions and decisions that happen in a logical predefined order to create some effect or outflow of data. I quickly realized that when workflow was applied to nearly any problem, the resulting solution was often both effective and innovative. I may have automated a monotonous task.

The number of times I typed:
NCICQV.NJ0191800.LIC/768KUL.LIS/NJ
to do an NCIC check, has to number in the tens of thousands. . . .

or it may have just provided consistency in the data entry. In fact, some of the most innovative ideas are simply a combination of tasks strung together to solve a problem.

This is where AI can directly lend itself to enhance any industry – through automation. There should be no great surprise, as industry has realized this back when Ford implemented the Assembly line. But, before I get too deep into this particular topic, I want to make one thing perfectly clear to my readers, while artificial intelligence can greatly assist in making decisions, we are not talking about totally autonomous AI. Realistically, we are likely still a long way off from true artificial intelligence. This is because common sense is not always a binary decision. But, one thing that we can benefit from today is the mathematic probability and the assistive advice that AI can provide. This is where we need to start to change our thinking, especially in areas of public safety or critical life affecting decisions, such as the medical field.

I’m liking this to the change in thinking that has taken place with testing in schools. When I was growing up, calculators still we’re still uncommon. Bringing one into a test would be considered ‘cheating’. Now, along with the text books that are required for a particular class, advanced engineering courses require a scientific calculator, and often suggest several models. Keeping this frame of thought in mind, let’s revisit the first example I mentioned previously in this blog, but this time, I’ll apply some assistive AI logic, and present this solution in the form of a simple flowchart:

EXMPLE JULY 4th CALL SCREENING WORKFLOW

The simplified logic here is fairly easy to understand. When a call arrives, the following decision points are considered.

• . Do I have a Call Taker Available?
• . If I do, then deliver the call. If I don’t, then determine if:
• . Is it July 4th between 20:00 and 21:00?
• . If not, que to the call takers, but if it is, intercept and play an informational message about where the fireworks are, and even direct them to the web for more information and safety tips.

Ideally this could eliminate many of the calls from tying up call takers, but those that need to speak to them are placed in queue, or routed elsewhere

This is done easily as once we play the message, we ask if they need further assistance, and disconnect, queue as needed, or even branch further to other common information resources.

Plan 9 from Outer Space?

Now, here is where we can really get a little far out with a solution.

By prompting the caller with an IVR, we can ask them if they’re calling from a mobile device?
(remember, in many markets this is a 80% – 90% of the call volume)

If the caller is on a text enabled device, we can clear them off the 9-1-1 line while offering them a more informative and interactive experience by simply pushing a web link to their device. Once the citizen clicks on the link, very simple HTML 5 technology can be embedded in the webpage that can extract their specific location, after they agree to share it, and then based on the response provide geo-targeted information that would be relevant to the caller.

This is a great transition into NG311 services, something that I’m getting asked about nearly every week. I’m convinced that the biggest success factor for a government 311 service, is the user awareness programs and publicity created by agencies. This could significantly reduce the number of  ”Information calls” into the 9‑1‑1 system, while providing a public resource, and an excellent EOC environment during disasters, as the basic premise of 9‑1‑1 call taking utilizes identical infrastructure on the backend.

I believe that this is one of the areas where Avaya brings technology to the table that a normal public safety vendor does not. They have the luxury of focusing on a very narrow use case of emergency services requests. But as communications evolve and become more multimedia in nature and omni- channel, the communications architecture embedded within public safety must involve with it or it wil lbe left behind, again. Those that want to play it safe by remaining stagnant, are actually depriving constituents of modern communications that could save lives.

To the current Sparta Chief of Police Neal Spidaletto, I remember you back in the early 80’s running around the house like a little terror, driving your Dad crazy. Congrats on your appointment as Chief, I am sure Joe is very proud of your career and accomplishments.

Testing 1-2-3 . . . PART Three – Location

By: Mark J. Fletcher, ENP
Chief Architect Public Safety Solutions – AVAYA

In PART Two of this blog, we discussed the Emergency Call
Network, that segment of the PSTN dedicated to emergency calling and connecting the PSAPs together on a regional basis. In this section, we’ll cover the mobility that modern networks provide to Enterprise users, and clearly one of the most challenging pieces of information for 9-1-1 call takers to obtain.

We learned that the Selective Router in the E911 Tandem office was responsible for connecting callers to the right PSAP. That decision is made based on the Caller ID presented with the call. Initially, this was a very valid best practice, as the network was well documented, and changes were well controlled and performed by the service provider.

One Number – One Address
Telephone numbers rarely were co-located in multiple locations (with a few
exceptions) therefore the telephone number was an excellent data point usable for determining the location of a device, and the network was designed around this fact. In the mid 80’s, the Northern Telecom DMS 100 was introduced as a digital central office platform, and AT&T introduced the ESS 5 with similar capabilities.

With these new digital switching platforms, the layout inside the Central
Office radically changed from one that was mechanical stepper-motor-based to one that used a digital switching matrix, and with this automation fewer and fewer CO’s were staffed with technicians, as the building role became merely a wire center with a cross connection point for dial tone to street pairs. With the digital evolution these switches brought was a new series of custom calling features.

A Star is Born
Customers did however get some very new features, like Caller ID and feature ‘STAR-codes.’
Missed a call? Dial *69 to be connected with the last number that called. *72
along with a telephone number would forward any calls to the new destination, and depending on the services provisioned in the CO, various other features became available to customers. Many of these features took advantage of Caller ID information that was now available with the call. For the very first time, the called person could know the identity of the caller displayed on their telephone device. Caller ID (better known as Automatic Number Identification or ANI) now provided 911 centers with information about who was calling, or at least the number they were calling from. Now, if a silent call came in, or there was a question about the address and location, the original color could be easily reached. 911 centers also played games with the electrical properties on the phone lines, and it was common practice not to pass any answer or disconnect supervision from the PSAP. This providing for a simple way to keep the line open simply by
not hanging up on the public safety end.

Location, Location, Location
Without a service address, it’s impossible to send any help at the time of an
emergency. To solve this problem, 911 centers begin taking the ANI (phone
number) they were receiving with calls, in making a query back into the carrier network database that routed the call. This ALI Automatic Location Information added location to the context for wireline calls, however the cellular industry didn’t catch up, and continued to report only Phase 1 location information, which was the latitude and longitude of the radio tower the cell phone happened to connect through. With the white density of cell towers, compared to today, the effective service areas were quite large spending several miles. When cellular towers were installed on mountaintops they often lined up with political borders, once again exasperating the location problem if you’re located across the state lines hitting a remote tower due to height and proximity. This problem remained for many years, and only began to be solved as devices started to contain GPS radio receivers, but there was still an underlying problem at the network layer level.

Can You SEE Me Now?
As the density and placement of cellular towers increased, Basic radio
coverage and interoperability became commonplace. Carriers started to
interoperate with each other, and cellular handoff became a commonplace feature spanning the entire coast. Making a call with simple, but making a 911 call remained problematic. Don’t get me wrong, calls could be received and routed quite simply, however since the 911 network is a legacy analog based network, and no data channel exists to pass information on, 911 centers went into making a query to the cellular carrier asking them what visibility was available out of their network. Despite the device itself having an excellent location awareness, due to Wi-Fi fingerprints, access points, cellular towers, as well as a GPS signal when outside, the location of you what is the network looking in, and what the device had (known as handset-based location accuracy) was simply unavailable to the PSAPs, and no mechanism existed to communicate anything other than a voice path between the caller and the call taker.

Google Can Find Me . . .
Yes, I am well aware that Google, Domino’s Pizza, and a plethora of other
services are you able to locate your cellular device with incredible accuracy; in the first responders at 911 that are trying to save your life, cannot. The primary reason behind this is that because the device is utilizing an application. Also, the application has access to the device-based  location information held in the memory. This particular location information uses all of the data points that we discussed earlier, and that information is communicated back over the Internet to the host application. Once again, this is where the train goes way off the rails.

The information that is contained within the device is like having a trans-Atlantic Ocean liner that is landlocked in a lake in the middle of Kentucky. Regardless of the level of luxury, the number of passengers it holds, or the amazing abilities contained within the ship, without any use cases or access to the ocean, you’re going to have a rusting pile of steel in just a few years.

Unfortunately, this is the exact state at our Legacy PSTN network exists in
today. Consumer-based technology, the information age of the Internet, and the digital transformation that has occurred in commercial businesses, have connected the world at levels never before conceived. The devices we carry our hands and our pockets, are capable of blinding fast speeds and connectivity levels never dreamed of before. I can call, I can video, I can text, and I can email anyone on the planet; except 9-1-1. My daughter, halfway around the world on a beach in Waikiki with her boyfriend can transmit real-time high definition video from her handheld device to my handheld device 4,882 miles away with practically zero latency, but if she had a medical emergency and needed help, she would be stuck with a voice call and location inaccuracy about half mile or more if she called 911.

In any commercial enterprise space, despite be vast amount of digital
information we have available about the emergent event, the situational
awareness about the emergency, or even lifesaving information about the caller, no matter what the technology is at the origination point, the network in the receiving agency are relegated too low fidelity text based information. Why? I’m not sure I’ve gotten a good answer to that . . . . yet. But I know a few young entrepreneurs that took the problem head-on, and drove a paradigm shift change in an industry that was half a century old and very much stuck in its ways.

In Part Four of this series, we will dive into over-the-top applications, that
utilize the Internet in the open connectivity that exists nearly everywhere to take a short cut around the technology roadblocks that lay between citizens who need help, in the public safety first responders that can provide that help.

Testing 1-2-3 . . . PART Two – 911 Networks

By: Mark J. Fletcher, ENP
Chief Architect Public Safety Solutions – AVAYA

In PART One of this blog, we talked about originating the call in the enterprise and the importance caller ID has in identifying the origination point of the call accurately to the PSAP.

Now that our emergency call has made its way out of the MLTS, navigated through the local Central Office (hopefully unmodified and intact), it has now landed within the 911 tandem Central Office where it is ready for location digestion and termination at the PSAP. The selective router, typically a Northern Telecom DMS 100, or a Lucent E5, has the specific job of providing connectivity between local area PSAP’s and the local Central office switches that serve dial tone to the public. While no hard fast rule exists, it is common to find that selective routers provide service in a specific geographic area that often (but NOT always) aligns with local calling area LATA jurisdiction. Once again, it is important to keep in mind that there is no hard fast rule here. While this legacy design has worked for years, the architecture happens to be one of the many things about the legacy network that is stifling innovation today.

Enterprise telecom providers and installers should be familiar with a few essential points here regarding the local selective router service areas. As they are often tasked with provisioning the MLTS properly. Generally speaking, the selective router tandem offices are designed in a hub and spoke fashion. They supply dial tone to PSAPs through specialized analog loop start CAMA trunks. While these trunks are in fact special, from a use perspective, the technology behind them is actually quite old, and has questionable value in today’s environment, given the changing mission and the need to include data elements and multimedia with the call.

Because CAMA trunks are analog based, loop start circuits, they are electrically no different that the POTS line that feeds your home. One important difference is that instead of normal DTMF tones, they utilize MF Tone signaling. Despite this, the most important characteristic is that they are ANALOG and NOT DIGITAL circuits. This means that any signalling between the endpoints of the circuit MUST be either voltage changes on the line (called battery), or in-band audio, leading directly to the first important point.

Caller ID / Location and E911
For calls transferred into the 911 tandem from the Local Central Office, the Caller ID takes on a level of implied authentication, and is matched against a selective router database table (SRDB) that determines the appropriate ESN or Emergency Service Number of the PSAP responsible for that physical address.

You can think of this Selective Router Service Area environment similar to a localized CENTREX model, with all of the PSAP’s interconnected by analog CAMA trunks. Calls can be transferred from one PSAP on the same selective router, to another PSAP on the same selective router simply by issuing a flash-hook on the CAMA trunk, and then dialing the ESN of the desired destination PSAP.

When this occurs, the call taker in the original PSAP can stay on the line with the call taker of the transferred to PSAP to ensure a warm handoff of the call and verbal information. This is done verbally as the interconnection is typically only voice. Once they’re no longer needed, the transferring PSAP can stay or disconnect, leaving the originating caller and the transferred to PSAP talking (now connected by the selective router).

This architecture eliminates the need for the transferring PSAP to hold the bridge on the call, which would tie up dual trunks to initiate the transfer and hold up the call connection. However, it limits where calls can be transferred, as the destination PSAP must be getting service from the same selective router as the originating PSAP. The exception to this rule would be in areas such as New Jersey, where the four selective routers servicing the state are interconnected with an SS7 network, and any PSAP can transfer to any other PSAP within the state network.

In areas where there is no inter-selective router connectivity, transfers to a PSAP that exists in a remote selective router must be accomplished using a 10 digit administrative line over the PSTN. BUT – because this call is going through the public toll network, the transferring PSAP must hold the bridge together between the caller and the transferred to PSAP.

Another downfall of PSTN based transfers is that it is often impossible to pass any data with that call (even caller ID), as these circuits are capable of voice only traffic, and the foreign exchange PSAP may not have access to the originating PSAP E911 network ANI/ALI database. Since selective router service areas never cross state borders, adjoining states with large population centers within their boundaries can find it very difficult, if not impossible, to pass calls between them efficiently.

A scenario causing a challenging problem for cellular telephones is the fact that electromagnetic radio waves never honor or limit themselves to a political border, and in fact, freely travel well beyond them. Exasperating this problem are areas where adjoining counties obtain service from different selective router facilities, such as Orange County Florida and Osceola County Florida.

A True Story that Prompted this Section
Recently, while driving west on Interstate 4, leaving NENA in Orlando, I witnessed a motor vehicle accident on the access road next to the highway. It had just happened, and were obviously going to require police assistance and a tow truck. Unknown to me, the actual location of the accident was just inside of the Osceola County border, but when I dialed 911 from my cell phone, my call was connected by the cell tower the the Orange County Sheriff’s Department 911 Center. I proceeded to explain the situation the best I could to the Orange County 911 call taker, who quickly determined that the incident was just beyond their border in Osceola County. She advised me she was transferring the call and not to hang up, and within 10 to 15 seconds, I heard the Osceola County 911 call taker come on the line. They advised them this was a transfer from a cell caller with an accident report and told me to go ahead.

I painstakingly recanted everything that I had just explained to Orange County, but the Osceola County call taker, questioned the location. I then asked if they got Phase 2 location on me, to help narrow down exactly where I was. I was then informed that because the transfer occurred as a 10-digit PSTN transfer, no ANI or ALI information was available to them.

Fortunately, both call takers were familiar with this troublesome location. Also, from the sound of it, both had their own techniques for coaxing the exact location out of the caller. However, it highlights a significant technology failure within the core E911 infrastructure, that is often masked by the hard-working dedication of our 911 call takers. Help gets to where it needs to be, despite the networking inefficiencies and technology roadblocks (like having to transfer emergency calls over the public switched telephone network) that blocks critical information from our nation’s 911 centers.

Given this example, with our cellular networks and mobility, you can only imagine the problematic environment that we’ve created in MLTS systems that’ll allow working from home with hard phones and softphones on laptops, and the connected world that we live in.

In PART Three, we’ll look at enterprise mobility, to better understand the problem, and start to explore potential fixes. Please remember to follow me on Twitter @Fletch 911, check out all of our other podcasts at http://www.Avaya.com/APN

Testing 1-2-3 . . . Where is your emergency?

PART ONE – The Originating Network
By: Mark J. Fletcher, ENP
Chief Architect – Public Safety at AVAYA

At Avaya, whenever a customer decides to review the implementation of emergency calling capabilities within their corporate telephone systems, we always stress two specific things.

The Plan:
First and foremost, is the implementation plan. Deciding exactly what the workflow needs to be – based on specific customer use cases that take their facility into consideration – as well as the various actions that make up that workflow. Critical details such as the reported response area size and the complexity of the internal floorplan must be taken into consideration, as well as the anticipated population of the facility, and the number and location of area entrances and egress points that would be usable during an emergency situation.

Testing:
Another important aspect is testing of the response plan. this must be done regularly to ensure that the plan is functional and provides an appropriate level of response. Also, the system itself needs to be assessed to ensure that the appropriate level of performance is being delivered, and that the proper level of information is being delivered to the PSAP.

While I am reasonably sure that no one would intentionally program 911 incorrectly, so that calls could not be dialed or that a wrong location would be purposely reported thereby delaying emergency response personnel, it is essential that the MLTS administrator clearly understands the various components and that the system is receiving the proper data, as well as operating nominally.

The most common mistake is one where no testing is done. Under this circumstance, the MLTS administrator makes the dangerous assumption that 911 is programmed correctly, and this leads directly to my question:

How does one know for certain that 911 is provisioned properly, without actually picking up the phone and dialing 911?

While this is the ultimate test, that does tie up valuable time and resources at public safety answer points across the country. With Kari’s Law legislation pending in the upcoming months (February 16, 2020), PSAP’s could be inundated with testing requests all the while fighting their constant internal battle of being already overworked and understaffed.

Unfortunately, without actually making a call to 911, the only way to ensure proper provisioning has been a “stare and compare exercise” by an MLTS technician or an MLTS administrator. First, they would log in to your system and extract a copy of your programming. Then, the person would manually walk through the dial plan steps, one by one, ensuring that an appropriate outbound trunk facility was being selected and that the calling line ID being sent over that trunk was appropriate for a 911 call, and was what they intended it to be to reflect the proper response address and internal location as per the design plan. While this simple exercise certainly caught any major programming problems and configuration errors, it did not provide a complete level of assurance that the system was actually working correctly.

How you ask? Simple, it’s called a false positive condition, and in 911 it could be deadly.

False Positives:
A false positive is a test result that indicates that there is no problem, when, in fact, one does exist. In the MLTS world, several things exist that could trigger a false positive when testing 911. Before we dig too deep into that, let’s understand the primary components involved in a 911 call between the MLTS and the PSAP.

When 911 is dialed, the call leaves the PBX on a specific facility. There are two pieces of information associated with the call at that point:

1.) The outbound Caller ID applied to the call, and
2.) The number as dialed by the originator (the called number)

The very first culprit of a false positive could be a physical one on the trunk facility itself. The CALLED number is simply established and is likely 911. However, the caller ID could originate from several different sources.

The very first thing to mention here is that the various types of trunks have different capabilities. Many like analog POTS lines, for resiliency, however, a little known fact is that when sending your 911 calls over analog loop or ground start trunks, the caller ID that is seen by the public network is the telephone number that is associated with that specific trunk.

Because the circuit is an analog circuit, custom caller ID cannot be applied, but this is precisely what gets your call routed to the right 911 PSAP, and the index they use to retrieve location information. Therefore, if you’re reporting uses building zones or the station location itself (both of which require dynamic caller ID) it is impossible to deploy this strategy using a POTS line, as the caller ID would always be the same for any calls on this trunk facility.

To utilize dynamic caller ID and any logic that is more granular than the building street address, the call must egress from the system on a facility that is digital, such as PRI or BRI, or direct SIP. This is true as these are digital protocols that support the transmission of a device identifier (telephone number).

Next-in-line is the originating central office. The responsibility of this central office is to connect local calls to other local endpoints on the same central office, and forward all other traffic to the toll switch and onto the long-distance network. For emergency calls, the local CO typically routes calls directly to the E911 tandem, also known as a Selective Router.

At the local CO level, applicable to digital circuit facilities only, there have been instances where the local central office provisioning on the inbound trunk group has been modified for 911 emergency calls. this can create a problem.

I have personally seen cases, where the inbound caller ID was modified, based on a previous trouble ticket. It turns out that improper programming on the MLTS caused invalid caller ID for 911 calls. To correct the issue, a central office technician implemented a translation table that forced any call with a destination of 911, through a table that stripped off any, correct or not, originating caller ID – replacing it with the main billing telephone number of the business owning the trunk group. Problem fixed – Sort of.

Since technology had not advanced yet, and an MLTS typically only served a single unique location, this logic corrected that particular problem of bad caller ID. Unfortunately, this apparent “fix” now masked the actual issue and created a whole new error condition if caller ID was to be used for location identification. Even more problematic, is that documentation is rarely kept current on why changes like this are made. Now, when they rear their head, it takes an incredible amount of effort and time troubleshooting to find the proverbial needle in the haystack, creating the issue at hand.

Now that we have our call into the actual 911 network, next up in Part Two, we will analyze what the network does with our call request, and what control we have over what takes place and how.

Kari’s Law – Countdown to Compliance

At the time I’m writing this, 477 days have passed since I stood in the Oval Office along with Hank Hunt as we witnessed Kari’s Law becoming the law of the land. While not strongly worded as such, the intent of the law was that, from that day forward, an MLTS phone system installed or put into service would be compliant with direct access to 911 without an access code, any calls to 911 would route directly to the PSAP and not be intercepted internally, and unless an upgrade was required, the system would provide some mechanism of notification that an emergency call took place.

Any existing MLTS systems that were installed prior to that date would have a two-year grace period in which to make their system compliant, with February 16, 2020 as the final date when legislatively this would be required. While system administrators and vendors have had almost 16 months to deal with the issue, many still have not. Now, with the deadline approaching quickly, the mad rush is on to secure system capabilities, and provide safe work environments for employees and guests.

Last year at the Avaya ENGAGE Event, Hank Hunt (Kari’s Dad) graciously sat down and recorded this video message:

Hank Hunt on Kari’s Law

Just a little more than a month after Kari’s Law was signed, the president signed Ray Baum’s Act, named in honor of a popular political figure that had recently passed away. The primary purpose of this act was to reauthorize the Federal Communications Commission and establish its operating budget.

With this act being a ”must pass” piece of legislation, it is popular for many other bills that will not stand on their own to become attached to it. One of those pieces of legislation is known as section 506 of the Ray Baum’s Act, and it has recently caused a bit of a stir in the MLTS community.

In this legislation, it establishes a requirement that the FCC conclude a proceeding within 18 months examining it further requirements are needed for location reporting on multi line telephone systems. The due date for that proceeding conclusion is September 23 of this year. This section calls off the need for a dispatchable location to be provided to public safety answer points when and MLTS initiates a 911 call. BUT, as I’ve said many times before, the most critical piece of any law is the definition of specific terms, and the same is applicable here.

In the Act, a dispatchable location is defined as one that, “means the street address of the calling party, and additional information such as room number, floor number, or similar information necessary to adequately identify the location of the calling party”.

Unfortunately, this is being hyped as requiring the exact room or cube number of the caller being delivered directly to the PSAP, when in fact that information is completely irrelevant without additional context. The fact that I sit in cube 2C-231, has no meaning to anyone outside of my company.

1st responders don’t know where 2C-231 is within the building, or even what floor it is on, so it has little relevance. It is very relevant, to internal first responders within the facility, and it could be provided to public safety first responders on an electronic display, and now with context, like a floor plan. This can now be provided directly with the 911 call itself, thanks to new over-the-top NG 911 technology provided by the Rapid SOS NG911 Clearinghouse.

Additional Context Available in the Enterprise

In the past, establishing 911 database records for every station within the facility created two problems. The first, was that every single device needed a unique and dialable public telephone number in order to identify itself, and secondly a unique record for each device needed to exist in the 911 ANI/ALI database, which incurred a significant monthly recurring cost. While at the surface, this seems to be useful information, it actually creates a false sense of security, as well as an administrative management nightmare, while providing minimal useful information. This is because in legacy solutions, the ability to pass additional context such as a floorplan is next to impossible.

Is this too much work, with no time to complete it?

Depending on the size and complexity of the enterprise, the 911 plan can be quick and simple to implement, or it may become a long drawn out process. This is where a waiver can help tremendously providing some additional time, where warranted. One of the initial states to adopt legislation was the State of Texas, Kari’s home State. During various hearings that took place in Austin, I suggested that waivers be granted to those that specifically apply for them, and as part of the application, the MLTS make and model number, as well as its software release be put on file, as well as evidence that a good faith effort was made to purchase a new system.

This simple clause solved a couple of primary issues. First and foremost, it forced businesses to make an effort and investigate what their situation was, and secondly it created a list of compliant MLTS systems, and release levels, which prevented unscrupulous distributors from up selling the general public when it wasn’t warranted. The waivers were good for one year, and needed to be renewed each September.

Since 2016 when the law went into place, the number of waivers filed each year has dropped by 20%, as more and more noncompliant systems were replaced with those that were compliant. As the graph below shows, in 2016, the very first year, 630 wavers we’re granted. In 2017, that number dropped significantly to 386, and in 2018 it was further reduced to only 252. Those systems granted a waiver also needed to make sure that users of their system we’re well aware of how to dial 911, with very specific placard requirements. Obviously, any new system purchased what have to be compliant upon installation.

911 is the most critical call you may ever have to make. As manufacturers of systems globally, we make sure that our users are well aware of this problem, and that’s why we stood behind Hank Hunt’s initiative on Kari’s Law from the very beginning.

Smarter Emergency Alerts

The Public Safety and Homeland Security Bureau (Bureau) is advising Commercial Mobile Service providers participating in Wireless Emergency Alerts of their obligation to support the following WEA improvements to the system by May 1, 2019:

  • Longer WEA messages (from 90 to 360 characters) on 4G LTE;
  • A new “Public Safety Messages”class of alerts;
  • Spanish-language alert messages;
  • Display of WEA messages as soon as they are received;
  • State/Local WEA Tests, with the ability to opt in.

The Federal Communications Commission (Commission) adopted these improvements to help communities communicate clearly and effectively about imminent threats and local crises, and to create a framework that would allow emergency managers to test, exercise, and raise public awareness about WEA.

Tackling Enterprise 911

Kari’s Law goes into effect for ALL SYSTEMS nationwide on February 16, 2020, after the expiration of a 2-year grace period allowing system administrators to become compliant. Kari’s Law requires businesses entities with multi-line telephone systems to provide the following capabilities on all phones:

  • Allow direct dialing to 911, without any prefix
  • Provide On-Site Notification when 911 is called
  • Route 911 calls directly to the local 911 PSAP

Avaya Partner Altura Communications has started a public awareness campaign in conjunction with Avaya and 911 Secure that is designed to inform customers of the issues at hand and offer solutions that are both functionally efficient and financially affordable. You can read their 3 part Blog series by Hank HuntMark Fletcher, and Kevin Kito on the topic here:

A Message from Hank Hunt

State of Emergency?

9-1-1. It is likely the most well recognized ‘brand’ in the world. It is the three digits every man, woman and child know by heart recognized around the world. 

To provide a dispatchable location to emergency responders today’s Enterprise telephone system administrators have relied on the Automatic Number Identification / Automatic Location Information (ANI/ALI) database for years. This database provided 911 dispatchers a cross-reference, or reverse lookup of telephone numbers to critical dispatch location addresses. Another function of this core component was to work in conjunction with the Selective Router Database (SRDB) used to route calls in the PSTN to the right agency. This allowed number portability, among other things

However, it appears CenturyLink has provided their Washington State Enterprise accounts with notice that they plan to discontinue their critical PS-ALI services effective May 8, 2019. After this date, enterprise customers must establish a replacement service of their own through a 3rd party provider.

They specifically state in their customer notice:

It is the responsibility of the customer to update the PS/ALI database (via a third-party vendor) with the individual station address information.

A copy of the new Tarifs regarding this change can be found online here.

Time for a change?

This is troubling, as the short window of remediation is going to require MLTS system operators to make a snap judgment on a technology they may not fully understand, and the predatory sales tactics of some providers may hook an Enterprise into a long-term contract for services with a minimal roadmap to the future of NG911.
