connectors in the second expansion cabinet" (page 69) on Figure 22
"Cable connectors in the second expansion cabinet" (page 69) .
3 Tag both ends of each cable with the cabinet or MG 1000S and
connector numbers.
4 Route cables down through the opening at the bottom of the cabinet
or MG 1000S.
5 Plug in the cables to the connector.
6 Replace the retaining bar after you have connected all cables to
the cabinet or MG 1000S.
7 Terminate the 25-pair cables at the cross-connect terminal.
8 Label the cross-connect terminal for each connector.
Figure 24 "SILC port designation label at the cross-connect
terminal" (page 69)
and Figure 25 "UILC port designation label
at the cross-connect terminal" (page 70) on Figure 25 "UILC port
designation label at the cross-connect terminal" (page 70) show the
label used with the BIX cross-connecting system.

Cross-connecting DSLs Each SILC provides eight four-wire, full-duplex
ports. These ports connect to the trunk wiring facilities (typically cabling
or wiring from outside the building) to form DSLs. Since the DSLs are
polarity-sensitive, maintain signal polarity along each loop as shown
in
Figure 30 "Cross-connecting an SILC port" (page 84) on Figure 30
"Cross-connecting an SILC port" (page 84) .
Each UILC provides eight two-wire full-duplex ports. These ports
connect to twisted pair trunk wiring facilities to form DSLs, as shown in
Figure 31 "Cross-connecting a UILC port" (page 85) . The DSLs are not
polarity-sensitive and it is not necessary to maintain signal polarity along
each loop.
Procedure 26
Cross-connecting DSLs at the cross-connect terminal
Step Action
To cross-connect SILC and/or UILC ports to the trunk wiring facilities:
1 Identify the card type (SILC or UILC) at the cross-connect terminal.
2 Identify transmit and receive pins on the top of the labeled distribution
strip for the card type you are connecting.
