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.
