Cables for External Timing

The figures in this section describe the crossover cabling necessary to

support a V.35 and an RS-422A Serial Port #1 with External timing. Note

that the cables are not

symmetrical.

The Centum Series units have female connectors and, therefore, the cable

connectors are always male at the Centum Series end. They will also be

male at the customer end unless specified otherwise.

Cabling

458-501776-015V.35 cross-over cable. M-series, 34-pin male
