Introduction
	This section describes the cable requirements for the T1/E1/PRI Card.
Cable
	The T1/E1/PRI card requires one of the following cables to connect to the
Requirements	T1/E1 network:

• RJ48-to-RJ48 twisted-pair cable to connect to a T1 network (minimum 26 AWG wire).

• RJ48-to-RJ48 twisted-pair cable to connect to a E1 network having 120-Ohm line impedance. (ETSI-TBR-013 requires that this cable be constructed of solid conductors of 0.4mm to 0.6mm.)

• 2 BNC-to-BNC 75-Ohm coaxial cables to connect to an E1 network that has 75-Ohm line impedance.

RJ48C Connector This table describes the RJ48C connector pinout:

BNC Adapter Cable A BNC adapter cable provides two BNC connectors to connect to an E1 network

with 75-Ohm line impedance. Use these adapter cables:

•BNC connector marked XMIT for transmit (TX).

•BNC connector marked REC for receive (RX).
