1. CROSS-CONNECT ROUTING RULE PARAMETERS

A. General Routing Rules

1.01 Several basic rules should be followed in routing

cables to the DSX system:

• Input and output digital signals should always be

in separate cables.

• DS-1, DS-1C, and DS-2 cables should not be routed

above bays or in a lineup associated with electro-

mechanical or crossbar switching equipment.

• DS-1, DS-1C, and DS-2 cables should not run

parallel with power or ground cabling.

B. Cross-Connect Lengths

1.02 The DSX cross-connect jumpers also add to digi-

tal signal-level losses depending on jumper length. To

assure reliable signal levels, maximum jumper lengths

recommended for each DSX frame are:

• DSX-1 and DSX-1C: 85 feet (25.9 m).

• DSX-2: 15 feet (4.6 m).

C. Cross-Connect Types

1.03 The recommended types of cross-connect wire

for each digital rate are:

• DSX-1 and DSX-1C non-shielded, tinned 24

AWG, twisted pair wire.

• DSX-2 Circuits Concentration Bay (CCB) type

cross-connect cords for Bantam modules, and

shielded pair 26 AWG wire with shield grounded

at one end for Longframe (310) panels.
