E&M/4 card (VB-44560): E&M Trunk Card
The E&M/4 card is a trunk interface that accommodates cards for the E&M Tie line
connections. Typically, tie trunks are used in network connections and for direct
connections to other PBX systems.
The incoming call address receiving control system supports the immediate and wink
method, and supports DP (10 PPS) and DTMF (only for wink) as incoming call
address signals. However, an MFR is required when the DTMF is selected. MFR is
supplied in CPC96, CPC288 and CPC576 card. Additional MFRs are available in an
MFR/8 card.
The E&M/4 card is mounted on a flexible slot to connect to a E&M telephone line.
The E&M/4 card provides a 4-circuit trunk interface on the card, and a lightening
arrester to directly connect to a E&M telephone line.
Note: To use the E&M/4 card, a built-in -48V power supply is required in the
same cabinet.
