Required
Equipment and
Tools
The following equipment and tools are required to make timing interface connections
to the Traverse main backplane:
•
2-pair 22 AWG (0.32 mm
2
) copper area wire (with drain wire
1
)
•
Flats or wire cutters
•
Wire-wrap tool for .045-inch x .045-inch (1.1 mm x 1.1 mm) posts
•
Electrostatic Discharge (ESD) wrist strap
(SDH network only) Optional equipment and tools required for SASE E1 timing source
connection with coax cables to the Traverse main backplane wire-wrap posts using a
75/120 ohm
balun (twisted-pair to coax convertor):
•
Coax cable and BNC connectors
•
75/120 ohm
baluns (2) or Traverse backplane cover with two 75/120 ohm
baluns
•
Coax cable cutters
•
Coax cable stripping tool
•
Coax center crimp tool
•
Punchdown tool for balun IDC connections
T1/E1 Timing
Interface Input
Follow these steps to complete T1/E1 timing interface primary and secondary
2
input
connections at the main backplane.
Note:
(SDH network only) You can run coax cable from the central office SASE E1
timing source to the Traverse shelf and use standalone 75/120 ohm
baluns
(user-supplied) or an optional Traverse system backplane cover with 75/120 ohm
baluns (and shielded twisted-pair wire) for connection to the main backplane wire-wrap
posts.
1
Drain wire required for shielding.
2
The secondary T1/E1 timing input connection is optional.
Important:
Always wear a properly grounded Electrostatic Discharge
(ESD) wrist strap when making connections to the Traverse main
backplane.
