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
page 57 shows the ADID faceplate LEDs and connectors. The ADID is available either in
four-port (ADID4) or eight-port (ADID8) configurations.
