84 Configuring ISDN BRI hardware
Refer to Table 16 "SILC and UILC port assignments connectors at
cross-connect terminal" (page 71) on page 84 to identify ports and
their pin numbers for a SILC or UILC.
3 Identify the trunk wiring facilities connected at the cross-connect
terminal.
4 Cross-connect the pins from the SILC or UILC to the trunk wiring
facilities.
5 Repeat this procedure for each DSL.
Note: For the system DSL in TE mode, reverse the TX and
RX pairs as shown in
Figure 32 "Connecting the ISDN network
terminator to the U interface and to the S/T interface (in TE
mode)" (page 86)
. Maintain the same polarity on the Tip and
Ring pins as for line application. Rewire the selected TX and
RX pairs to exchange their TX pairs with RX pair position.
This procedure is required since SILC cards are designed for
applications in the NT mode.
