Step Procedure
1 (SDH network only) Are you using coax cable (instead of twisted-pair
wire) from the central office SASE E1 timing source to the Traverse main
backplane?
• Yes. Connect timing coax cables to the SASE E1 primary and
secondary timing source and run the cables to the Traverse shelf
following local procedures. Continue to Step 3.
• No. Go to the next step.
2 Connect 22 AWG (0.32 mm
2
) timing wires to the central office
BITS/SASE T1/E1 primary and secondary (optional) timing source and
run the cables to the Traverse shelf following local procedures.
Note: Two 2-pair wires are required for primary and secondary
(T1/E1_INA and T1/E1_INB) connections.
3 Route the T1/E1 primary and secondary timing wires across the horizontal
cable rack and down the rack rails to the left side of the Traverse shelf.
4 Remove the back cover from the Traverse shelf. Refer to
Section 6—
Precautions and Common Procedures ,
