911 for seperate buildings 2

[george630us]

Hi, we have a 2.1.1 s8500 with ISDN PRI that services multiple buidings on our campus environment. The "outer" buildings are connected to the main building via copper. One of the buildings is on the other side of a public road and has a different street address than the main building.

My concern is with 911 calls originated from the outer building. The 911 center sees the street address of the main building instead of the outer building.

Has anyone dealt with this type of situation? I'm considering installing a couple trunks from the LEC in the outer building, bringing them to the main campus over our copper and installing them in the s8500. I would them partion and routing for those stations in the outer building.

You could provision 1 or 2 analog POTS lines to the outer building, making sure that the billing address reflected the actual address. Putting those extensions in a different Partition Group than the main site would give them access to a different Reoute Pattern (and Trunk Group)for 911 service.

I'm assuming you have checked all the municipal codes in your area, but there may be a law requiring 911 compliance for your type of setup. For example, I know multi-story buildings and campus-style environments require 911 compliance to provide ANI (Number Identification) and ALI (Location Information) information to the Public Service Answering Point (PSAP). At least in the Chicagoland area.

If building A has a block of DID's say 4000-4099 and building B has 4200-4299 You could have the phone compan;y change the address on the block of DID's for building A and solve the problem that way.

I have IP Setup in a building a few block away. I installed some POTS lines for 911 use, and I am considering blocking 911 from their phones, is this possible to do with the 4620? I can do this easily with the softphone but there is not an option with the 4620 station form that I could see....

Thanks in advance for your help!

I have a similar setup here. PBX at corp address "9" and warehouse at "5", all through PBX at "9" address. With PacBell (SBC) here in Southern California, I contacted their Enhanced 911 group. I built a route and trunk group so that outbound 911 calls always send the unique DID station number out over the PRI. Then SBC gives me direct control of my DID numbers in the 911 database. I update the address and detailed location info (lobby, 2nd floor, etc.) myself so any 911 calls will always have the correct information. There's a nominal monthly fee for a secure access card, but otherwise it's free, just a little time to setup. Works great.

TivoNut,

Thanks - Excellent info. I just sent my SBC rep a request for the secure access card. Do you know where I can locate the info on how to setup the route/trunk in the PBX?

I have a single local PRI that my outbound local calls are routed on. It's in a single trunk group of 23 channels. Calls out this trunk group normally only send our main number as caller ID on all calls (via ISDN Pub-Unk numbering). In order to get 911 calls to deliver individual DID numbers, I had to split this group up. I built a new trunk group, moved 3-4 of the channels from my main local PRI group into this group. Then changed ISDN Pub-Unk to send full DID numbers out over this trunk. Next I added a route pattern listing this new trunk group first and the old one second. Lastly, added an ARS entry for 911 to point to this route pattern.

You can test by making an ARS entry for your cell phone, point it to this route pattern and dial your cell. In fact, I left my cell phone and a few others pointed to this pattern, so when someone calls my cell from the PBX I know who it is.

TivoNut,

Thanks for all of that info. I appreciate your time!

Thank You TivoNut, I'm checking with SBC. One question, are all your extensions DIDs? We have many extensions that don't have a DID associated with it.

 

[TivoNut]

Pretty much all of our extensions are DID. In your case, for ones that are not, make sure that extension sends a valid DID that is at the same address. This is easily accomplished via the ISDN Pub-Unk numbering in the switch.

When implementing this 911 stuff, you end up becoming responsible for what numbers report what addresses in the 911 database. So it's important to remember that any time and extension is moved, added or changed, you need to update the 911 database if the change is significant. So moves of extensions within the building may not require a change, but moving them between buildings will. Also, moving within a building may require a change if you've provided more detailed information, like 2nd Floor, 4th Floor, etc.

Good luck
