Page 50

50 Appendix A Technical specifications

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 1 and 2) and the receive signal (pins 7 and 8). Nortel strongly recommends that you use factory-made 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.

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. Do not interchange the 56/64K CSU/DSU crossover cable and the Ethernet crossover cable.

Table 18 provides the 56/64K CSU/DSU cable pinouts for a crossover connection.

The cable operates properly if you do not connect pins 3, 4, 5, and 6.

Caution: For crossover connections, do not use Ethernet cable. If you use Ethernet cable, the link cannot be established.
