T1/E1 CSU/DSU WAN interface card
The T1/E1 CSU/DSU WAN interface card has a single connector that provides
the signals needed to interface to T1 or E1 equipment. This interface card ships as
a half-height card and as a full-height card.

The connector on the T1/E1 CSU/DSU WAN interface accommodates an 8-pin
RJ-48 modular patch cord. These cables are commonly sold as Category 5, or
Ethernet, cables.
Use cable that is wired in accordance with EIA-568-A wiring style. This wiring
style ensures that a twisted pair inside the patch cord carries the transmit signal
(pins 4 and 5) and the receive signal (pins 1 and 2). Nortel strongly recommends
that you use professionally manufactured patch cords.
Note: For E1 service, you must install the half-height version of the
T1/E1 CSU/DSU WAN interface card.
Note: Nortel does not supply the T1/E1 CSU/DSU WAN interface
cable with the WAN interface card.
