Panel Cabling
Follow these steps to make the connection at an intermediate DS1 or E1 patch panel
and the central office cross-connect panel:
Table 8-8 DS1 (100 ohm) and E1 (120 ohm) Panel Cabling
Step
Procedure
1
Terminate Output (O) and Input (I) DS1 or E1 cables to the intermediate
DS1 or E1 patch panel using a wire wrap tool.
Note:
Each working 28-port DS1 card requires 28 output and 28 input
connections at the patch panel (for each DS1 cable terminated) and at the
cross-connect panel. Each working 21-port E1 card requires 21 output and
21 input connections at the patch panel (for each E1 cable terminated) and
at the cross-connect panel.
2
Label the cables to designate Output and Input per local procedures.
3
Route the cables from the patch panel across the horizontal cable rack to
the cross-connect panel, per local procedures.
4
Cut the cables to the correct length using cable cutters.
5
Terminate Output and Input cables on the cross-connect panel using a wire
wrap tool.
6
Repeat Step 1 through 5 for each DS1 or E1 cable terminated at an
intermediate DS1 or E1 patch panel.
7
The DS1 (100 ohm) and E1 (120 ohm) Panel Cabling is complete.
