Analog direct inward dialing media bay module

The analog direct inward dialing (ADID) MBM provides an interface for four or eight analog

public switched telephone network (PSTN) lines. The ADID MBM supports both pulse and tone

dialing as well as disconnect supervision, and direct inward dialing call progress signaling as

described in standard TIA-464C.

The ADID MBM uses an RJ-21 connector for trunk connections. The figure ADID faceplate on

page 47 shows the ADID faceplate LEDs and connectors. The ADID is available either in

four-port (ADID4) or eight-port (ADID8) configurations.
