911 at remote sites 1

[nortel23]

I've had some issues with 911 lately. 1 being because they don't know how they want to handle the calls at remote sites. I also recently found out they have enhanced 911 at this site as well. We have an 81 c switch with 4 remote sites. When 911 is dialed all calls notify the security desk of the number and location.The trunk dials the the 911 center were the 81c is located providing that address. Thats fine for the phones at the location were the 81c switch is located. They want the remote sites to be able and dial 911 and have the calls go to the proper site of were the call is located. The DID numbers are reside at the location of the 81 c switch. Any ideas of were to start. I suggested providing local numbers for those sites and only use those numbers at those sites. Im sure someone has another idea open to suggestions.

If you have a 1FB at remote sites and a Universal Trunk card you can probably solve this. The 1FB will have the remote's site appropriate address associated with it. Build a COT route in ld 16, 1 member in the route in ld 14 on your UTC port, wire the 1 FB to the UTC port, build rlb in 86 using the new route, 911 as SPN in ld 90 and choose the new RLB from 86. Then, when a remote site person dials 911, they should get the local authorities and display the correct building address. And, you can test call 911 (not often) and when you do please inform you are telco doing emergency services testing and do they see the correct address.

The phones for 911 are controlled by the tgar now. When someone moves from 1 building to another the tgar needs to be changed.Can this be done by the ncos which is basically being done in ld 86. Will it be nesesary to dial 9911 because they only want to dial 911 at each site.

i would build an idc for the route comming from each site and send the call back out to that sites 911 center unless the remote site has local trunks.. if they have local trunks at the remote site, route spn 11 to the local 911 center with the local clid.. spn 11 when routed thru a dgt, del 2 insert 911 and pick the local route would be the simplest way and not conflict with any other dsc's usually

Ive been able to get my universal trunk card to be accessed
with the access code. But now Im hsving trouble with it when you dial 9911 the call goes to the wrong rdb and provides the wrong address at the 911 center. I set up the rdb and put the targ in the rdb to the same as the phone tgar that Im calling from. I modified the rli to include the new route as well. What else can I look at?

I set up the rdb and put the targ in the rdb to the same as the phone tgar that Im calling from

that by itself is a block.. i would look at spn 11, add it if needed.. point that to a local route with a dgt that deletes 2 and inserts 911.. that allows 911 the rlb puts it on the right route.. you can also point 911 to the route by adding an rlb with out a dmi but still pointing to the same route.. you don't want to use tgar/targ in most ac1 ar ac2 routing.. just use those for acod routing... for example, my code blue overhead page has a targ of 6 so all my patient and courtsy phones have tgar 6.. they can't access my overhead

Thanks John I modified my rdbs that I have to not have the same targ as the tgar. ex If I have a tgar of 17 I made sure the rdb that I am using dose not have that defined in my targ. The other rdbs I added the the targ for 17 to them.

This has been fun.

Im sure they will start asking of instead of entering 9911 at my remote sites they will wnat to only dial 911. I do not think that will be possible because they are using enhanced 911 providing the location of each phone and sending that information to a security desk.

your right, sending 11 to 911 does bypass the enhanced 9,911 routing.. if i send both i usually capture cdr to a file so they can at least track the dn that called.. if the customer paid for e-911 i wouldn't bypass it.. don't mention how much fun we have doing our job, management might catch on...

Referencing enhanced 911.

If I am using this enhanced 911 at my main site off an option 81c, can 9911 be used at the remote sites using a universal card to dial the correct 911 center and also report the location of the person that called the 911 at that location like the enhanced 911 works?

These remote locations are not reporting the location of the caller when they dial 9911.
