5.9.5 E1/T1 Cables
You must provide an RJ-48 cable for each E1/T1 connection. Select a standard unshielded
twisted pair (UTP) male-male cable with RJ-48 connectors, at least 26AWG, or 0.4mm.
NOTE:
Install a ferrite on each cable that connects to an E1/T1 port when installed
and operated in the European Union: Steward ferrite 28A2024-0A0, Part No.
332-0003-000.
The following table describes the RJ-48 pinout required for E1/T1 ports.
NOTE:
An E1/T1 interface is hard-strapped as
NT
by default for connection to
TE
equipment. Use a crossover cable where
TE
mode is required for connection
to
NT
equipment.
