Cross Reference Tables to J-STD-036-A

The intention of this section is to provide a method for a WSP to assess which type of BellSouth supported
SS7/ISUP signaling option can best fit their needs. Each decision MUST take into account the capability
of the WSPs MSC and the capability of the PSAP CPE, and may be impacted by the type of ALI steering
options involved.
The following pages in this section represent the different interconnection scenarios that are described in
J-STD-036-A for Wireless E9-1-1 Phase 2.
A.8.1

Wireline Compatibility Mode (NDET uses signaling option E911_STD)

If the WSP will be using a Wireless E9-1-1 Phase 1 Non Callpath Associated Signaling (NCAS) Solution,
as described in J-STD-034 or Wireless E9-1-1 Phase 2 Wireline Compatibility Mode, as described in
J-STD-036-A to deliver the Call Back Number (CBN) and/or x, y coordinates to the PSAP via the
ALI database, Table "A" below describes an acceptable interconnection method (known as Wireline
Compatibility Mode in , as described in J-STD-036-A). In this interconnection method ONLY the pANI is
sent into the BellSouth NDET, directly from the WSPs MSC over dedicated trunks. The pANI is used by
the NDET for selective routing, and then the pANI is sent to the PSAP the same way ANI would be on a
landline call. That may be as an 8 or 10 digit number, depending on the capability of the PSAP CPE.
The NCAS or WCM Solution provider is expected to create a record in the BellSouth ALI database that
will contain the CBN (among other data normally included by the NCAS provider, which may or may not
also include Phase 2 data). That activity is beyond the scope of this document.
Extracted in part from Annex D: of J-STD-036-A, clarified for use in BellSouth.
Table "A" ISUP Initial Address Message Parameter Contents for Wireline Compatibility Mode (ESRK).
In this mode only the ESRK is sent as the ANI over dedicated trunks to the Selective Router because the
trunk between the Selective Router and the PSAP supports transport of only one 7/10 digit number.
