Procedure 9
Cross-connecting SILC and/or UILC ports to the building wiring
Perform the following steps to cross-connect the SILC and/or UILC ports to the
building wiring.
1 Identify the card type (SILC or UILC) for a connector on the MDF. Refer
to the IPE or CE module card location form at the end of this chapter,
which shows the card type connected to each I/O panel connector.
2 Identify transmit and receive pairs on the top of the labeled distribution
strip for the card type and module type you are connecting. To identify
SILC or UILC ports and their pin numbers, refer to Tables 5 through 11,
which begins on page 37.
Note: In Tables 5 through 11, the cable pair designated T- T+ is the
transmit pair and the pair designated R+ R- is the receive pair of the S/T
interface. The cable pair designated T R is the Tx and Rx of the 2B1Q
full-duplex U interface.
3 Identify building wires connected to the bottom of the distribution strip.
Refer to the Building Cable Plan, which identifies wires between
distribution frames and wall outlets. The Building Cable Plan is developed
according to instructions in the "Planning the Site" section in
Communication Server 1000M and Meridian 1 : Large System Planning
and Engineering (553-3021-120).
4 Plug in the terminating resistor at the appropriate location in each S/T
DSL. See "Engineering Guidelines" in the ISDN Basic Rate Interface:
Features (553-3001-380) for engineering rules and locations of
terminating resistors.
