Chapter 2. System Overview
DID/8 card (VB-44520): DID Trunk Card
The DID/8 card is a trunk interface that accommodates cards for the DID dedicated
incoming function.
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 DID/8 card is mounted on a flexible slot to connect to a DID telephone line,
making detection and answering of call signals from the trunk and speech possible.
The DID/8 card provides an 8-circuit trunk interface on the card, and a lightening
arrester to directly connect to a DID telephone line.
Note: To use the DID/8 card, a built-in -48V power supply is required in the
same cabinet.
The switch settings and LED indications are the same as for the LTRK/8 card (VB-
44510). See Table 2-12 and Table 2-14.
