Chapter 3 - System Installation
Station Connections
The system can be equipped with any combination of the six station boards; DTIB12, DTIB24,
ETIB, SLIB, SLIBE, and SLIBC. The station interface boards can be installed in any universal card
slot in the Cabinets. It is recommended that slots beginning from slot 0 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 by default), it is strongly recommended that a
DTIB12 or DTIB24 be installed in slot 0 and a Digital Keyset w/LCD be connected to the first
port.
Electronic Telephone Interface Board
The Electronic Telephone Interface Board (ETIB) board provides the interface to twelve
electronic telephones or DSS/BLF 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.
The only telephone that can be used for database programming is the digital
Executive display telephone.
