DID Interface Board

The Direct Inward Dial Interface Board (DIDB) provides four analog DID CO interface ports.
The DIDB can be optionally equipped with a DTMF Receiver Unit (DTRU) daughter board to
detect DTMF tones.
Installing the DTRU Module
1. Unpack the DTRU Module from its antistatic conductive bag.
2. Locate the CN1 and CN2 connectors on the DTRU module.
3. Locate the CN1 and CN2 connectors on the DIDB.
4. Position the DTRU module so that the CN2 and CN1 connectors match up with the CN1
and CN2 connectors on the DIDB respectively.
5. Push the DTRU module onto these connectors making sure it seats properly.
XTS-IP - Installation Manual
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.
