PCTFI card
Table A-17 describes the PCTFI slot card status lights.
Connecting the PCTFI slot card to the switch
The time-slot interchange unit of the 5ESS switch uses two BKD10 boards, installed as a
time-slot interchange slice (TSIS) board pair. One BKD10 board is inserted into TSIS side 0.
The other BKD10 board is inserted into TSIS side 1.
The PCTFI card connects to the BKD10 board-pair with a pair of 62.5 micron (
µ
m) fibers with
MT-RJ connectors at both ends. Each fiber must not exceed 2000 feet (610 meters).
Each peripheral control and timing (PCT) facility interface link is a duplexed connection, with
one active and one standby link. The 5ESS switch determines which side of the duplex PCT
facility interface is selected for data transmission.
