E1/DS1 cable pinouts and assemblies

Cable details

The 28xE1/DS1 circuit pack supports 64-pin Telco connectors to offer the
E1/DS1 services. By default, the ports are 120/100 ohm balanced E1/DS1
electrical ports. A termination panel can be used to convert the 120 ohm
balanced E1 ports to 75 ohm unbalanced E1 ports.
The following sections detail the pinouts and port mappings for the 120/100
ohm cable assemblies and for the 75 ohm termination panel. The E1/DS1
cables come with right routing.
These cable assemblies can be ordered from Nortel (see
