911 will be inplemented here (Waco, Texas) later this year. Our PBX
(Northern Telecom SL1-XT) has the capability to send caller information to
the CO (ESS) either by ANI or AIOD. The 911 implemention team was satified
with knowing that a call came from Baylor University and leaving it at that.
But we felt with over 4000 telephones on campus, we should do a better job
of providing locations to the emergency services. We are now investigating
the possibility of providing extensions whenever a call is made to 911.
Has anyone else set up 911 location information service from a PBX.
Please send any recommendations, advice, and experiences.
Thank You

How are you proposing sending more digits/extensions other then the phone numbers administered by your local operating company? If you are only getting basic 911 service without ANI/routing capabilities sending more information from your PBX own't help the PSAP. On the other hand, if you are going to connect into an Enhanced 911 PSAP I have a few questions. An Enhanced 911 PSAP has an address database that must be maintained by someone, how or will the university keep the database informed of extension moves. Will the PSAP even want to know about these numbers? If you are going into an E911 PSAP could it even handle a DN followed by an extension? I didn't think E911 was currently capabile of this. If the E911 is going to be used for routing the calls and your university is split over multiple juristictions I believe most of the call routing will be based on the PBX trunks billing number now originating extensions, since that is a reason for most PBXs to provide extensions not necessary known to the local switching offices.
