DS3 Cables

The DS3 interface uses SMB connectors. Use commercially-available cable and connector assemblies for all DS3 connections. These cables have the following characteristics:

Male SMB connectors
75-ohm RG-1xx coaxial cable

Ethernet Cables

The management and Fast Ethernet interfaces use RJ-45 connectors. The cables require Category 5 shielded twisted pair cables terminated with RJ45 connectors. These connectors have the following pin assignments:
