Station Wiring
Station interface boards (DTIB24, ETIB, SLIBE, SLIBC) include a 25-pair connector for station
wiring to the ports on the board. The following provides details on the interconnection of
each type of station interface board and the station jack.
Digital Keyset and Terminal Wiring
Wiring from the DTIB to the station jack requires 1-pair wire cabling (category 3 or higher).
Wiring from the station jack to the telephone requires 1-pair wire. Digitized voice, signaling and
power are sent over this pair.
Figure 3-40 gives details on connections of station jacks to the system and Table 3-20 gives the
configuration of the 25-pair station connector arrangement and punchdown-type block.
