Connecting the T1/E1 Trunk
Port to the Network
If you are using a T1/E1 network interface, connect
the T1/E1 trunk port to a network demarcation
device.
If the trunk port has an RJ-48 jack, use an RJ-48
straight-through cable (not included), or a special
cable if required for your application.
If the trunk port has BNC connectors, use two
75-ohm coaxial cables with BNC connectors (not
included).
Note: The T1/E1 trunk port, when present, has a
built-in CSU/DSU for connection to a service
provider's network interface.
