V.90 Modem Interface Card - Nortel Contivity 2600 Install Manual

Each connector on the quad T1/E1 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.
Use cables you 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.
You connect the quad T1/E1 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.
