Cross-connect SILC and/or UILC ports to the building wiring

1Identify the card type (SILC or UILC) for a connector on the MDF. Refer to the IPE or CE/PE module card location form, which shows the card type connected to each I/O panel connector.

2Identify 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 4 through 10, which follow the illustrations.

Note: In Tables 4 through 10, 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.

3Identify 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.

4Plug in the terminating resistor (Part Number A0378866) at the appropriate location in each S/T DSL. See “Engineering Guidelines” in the ISDN Basic Rate Interface: Product Description (553-3901-100) for engineering rules and locations of terminating resistors.
