Station Connections; Electronic Telephone Interface Board (Etib) - Vodavi Starplus Triad 1/2/3 Installation Manual

Station Connections

Station Connections
The system can be equipped with any combination of the four station
boards; DTIB12, DTIB24, ETIB and SLIB6. The station interface boards can
be installed in any card slot in the BKSU and EKSU, except for MPB slot of
the BKSU. As a default, the software allocates slots 1 through 5 of the
BKSU and 9 through 10 of the EKSU for station interface boards. It is
recommended that slots beginning from SLOT #1 be used for station
interface boards. Also, since the first port of the DTIB is the database
access port (the only port which enables Admin programming), it is
strongly recommended that a DTIB be installed in the SLOT #1 and a
Digital Keyset w/LCD be connected to the first port.

Electronic Telephone Interface Board (ETIB)

The ETIB board provides the interface to twelve (12) electronic
telephones or DSS/DTS terminals. The card has one LED indicator for
off-hook/in use status. The ETIB card extractors are color coded green.
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). 25-pair telephone cabling must be prepared
with mating connectors to extend the interface circuits to the MDF. The
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.
Only DTIB type stations can be used for Database programming.
