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 83)
"Cross-connecting an SILC port" (page
: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
polarity-sensitive and it is not necessary to maintain signal polarity along
each loop.

Action
Identify the card type (SILC or UILC) at the cross-connect
terminal.
Identify transmit and receive pins on the top of the labeled
distribution strip for the card type you are connecting.
Refer to Table 16 "SILC and UILC port assignments connectors
at cross-connect terminal" (page 70)
identify ports and their pin numbers for a SILC or UILC.
Identify the trunk wiring facilities connected at the cross-connect
terminal.
Cross-connect the pins from the SILC or UILC to the trunk wiring
facilities.
