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.
Figure 39 shows the T1/E1 CSU/DSU WAN interface card (half-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.
Note: Nortel does not supply the T1/E1 CSU/DSU WAN interface
cable with the WAN interface card.
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.
