Direct Inward Dial Board
The Direct Inward Dial Board (DIDB) provides four analog DID CO interface ports. The DIDB can
be optionally equipped with a DTMF Receiver Unit (DTRU) to detect DTMF tones. If a DIDB is
used, a DTRU is required; it does not necessarily have to be mounted on the DIDB, but it must
be installed within the system.
