We are replacing a Definity w/CCM 4.1 and need to re-use the existing paging equipment. In the PBX is a 763B Auxiliary Trunk Card which connects to a 278A Adapter. The pinouts for the 763B card are:
T R S SZ S S1 (the S & S1 leads are equivaqlent to E & M).
We are using a VIC2-2E/M card setup as a Type II E&M trunk - this works fine. We can activate the E&M port with an access code and establish a talk path. The problem comes in matching up the wiring of the VIC2 with the 278A adapter.
Has anyone successfully done this on this specific Lucent paging adapter? Your input is appreciated.
Re: Paging configuration using Lucent 278A adapter
The Lucent 1AESS local exchange telephone switching system was widely deployed in the 1970s across what was then the Bell System. During the past two decades, most 1AESS switches have been replaced by the next-generation digital switches, such as the Lucent 5ESS and Nortel DMS-100. While few 1AESSs remain, those still in service are generally heavily built out?about 2 to 5 percent of lines are on 1AESS switches.
Service providers that offer wholesale dial, Internet/intranet, and access virtual private networks (VPNs) require remote access and expect to provide widely available service at the lowest cost. To do so, they must have Signaling System 7 (SS7) trunks to each local exchange in a service area. And for the Internet service provider (ISP) or competitive local exchange carrier (CLEC) wanting 100 percent dial coverage, interfacing to the remaining 1AESSs is mandatory.
Using SS7 signaling avoids investment in central office circuit switches, which must be used as concentration points for dial-in traffic to the access servers when ISDN Primary Rate Interface (PRI) or in-band trunk signaling is used.
This feature provides 1AESS support for Cisco AS5400 universal gateway access servers. The configuration is on a T1 basis: one or several T1 lines are designated to support 1AESS, but no fractional T1s (FT1s) can be configured.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
