Digital Telephone Interface Board (DTIB)

The DTIB board provides the interface to twelve (12) digital telephones. It
is offered in two (2) versions, a 12-circuit and a 24-circuit. The card has
one LED to indicate off-hook/in use status. The DTIB card extractors are
color coded green.
Cables
There is one 50-pin female amphenol connectors labeled Conn2 located
on the front of the card. This allows the system to be cabled to the main
distribution frame (MDF).
Only one stationisallowedperdigitalextension number.Itis notpossible
to bridge digital station ports so that an extension number may appear
in more than one location.
25-pair telephone cabling must be prepared with mating connectors
to extend the interface circuits to the MDF.
Cables should be routed through the cable clamps at the bottom of
the KSU to the MDF. These cables are then terminated on industry
standard 66M1-50 type punchdown connector blocks.
It is recommended that 66M1-50 split blocks with bridging clips be
used to simplify troubleshooting and to quickly isolate faults.
