The connector on the 56/64K CSU/DSU WAN interface card accommodates an
8-pin RJ-48 modular patch cord.
Note: Nortel does not supply an interface cable with the
56/64K CSU/DSU WAN interface card.
Use cable that is wired in accordance with ANSI T1.410 wiring style. This wiring
style ensures that a twisted pair inside the patch cord carries the transmit signal
(pins 1 and 2) and the receive signal (pins 7 and 8). Nortel strongly recommends
that you use professionally manufactured patch cords.
You connect the 56/64K CSU/DSU WAN interface card to the service provider
network using a straight-through cable or a crossover cable, depending on how the
service provider wired its jack.
