Repeat Steps 1–6 for cabling at each E1 ECM.
5
Tie-wrap cables to the cable management bar following local procedures.
Important:
Mount a second cable management bar for strain relief with
Mini-SMB ECM cabling. Optionally, use a second cable management bar
for any copper cabling exiting the rear of the shelf.

6
Is an intermediate patch panel installed in an equipment rack for
termination of the cables?
•
Yes.
Route the cables to the intermediate patch panel located in the
same or adjacent rack per local procedures.
•
No.
Route the cables up the rack rails to the horizontal cable racks and
over to the central office cross-connect panel per local procedures.
7
Cut E1 cables to the correct length using diagonal cutters.
Important:
E1 coax cable length, from the Traverse shelf to the
intermediate patch panel or cross-connect panel, must not exceed 450 feet
(137 meters) to meet pulse template requirements.
8
Strip and terminate connectors on the cables using a coax stripping tool
and crimp tool.
9
Terminate Output (O) and Input (I) coax cables on intermediate patch
panel or central office cross-connect panel.
