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.

Connect the 56/64K CSU/DSU WAN interface card to the service provider network by using a straight-through cable or a crossover cable, depending on how the service provider wired the jack.
