HDSL Wiring
J4 - J19 on the PCS-719 backplane correspond to COLU slot numbers LU1 to LU16. Figure 12 shows HDSL
connections for J4 and J5. The wire-wrap pin labels for J4 - J19 correspond to the COLU slot number (LU1, LU2,
etc.). In
Figure 12 , DSL_A-1 is for the primary HDSL connection to COLU slot 1 (LU1). For COLU slot 16
(LU16), the wire-wrap pin label would read DSL_A-16.
To make the wire-wrap terminations on the HDSL using one pair leads:
1 Use a wire-wrap tool to terminate HDSL pair #1 onto the T (Tip) and R (Ring) wire-wrap pins labeled
DSL_A-1.
2 Terminate the remainder of the required HDSL pairs onto the T and R wire-wrap pins on terminals
DSL_A-2 (LU2) through DSL_A-16 (LU16):
To make the wire-wrap terminations on the HDSL using two pair leads:
1 Use a wire-wrap tool to terminate HDSL pair #1 onto the T (Tip) and R (Ring) wire-wrap pins labeled
DSL_A-1.
2 Use a wire-wrap tool to terminate HDSL pair #2 onto the T (Tip) and R (Ring) wire-wrap pins labeled
DSL_B-1.
3 Terminate the remainder of the required HDSL pairs onto the T and R wire-wrap pins on terminals
DSL_A-2 (LU2) through DSL_A-16 (LU16) and DSL_B-2 (LU2) through DSL_B-16 (LU16).
