The connector on the 56/64K CSU/DSU WAN interface card accommodates an
8-pin RJ-48 modular patch cord. These cables are commonly sold as Category 5,
or Ethernet, cables.
Note: Nortel Networks does not supply an interface cable with the
56/64K CSU/DSU WAN interface card.
The cable you use should be wired in accordance with EIA-568-A wiring style.
This wiring style ensures that the transmit signal (pins 1 and 2) and the receive
signal (pins 7 and 8) are carried on a twisted pair inside the patch cord. The use of
factory-made patch cords is strongly recommended.
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.
• For a straight-through connection, you can use a standard Category 5
(Ethernet) straight-through cable.
• For a crossover connection, you cannot use a standard Category 5 crossover
cable. The 56/64K CSU/DSU crossover cable and the Ethernet crossover
cable are not interchangeable.
Table 16 provides the 56/64K CSU/DSU cable pinouts for a crossover connection.
