VPN Router 2750 1100)
Select cables for this card as follows. Keep in mind that this card is
auto-negotiating and uses the highest possible data rate:
• For 1000BASE-T operation, use Category 5 four-pair Ethernet wiring. The
cable must comply with the TIA 568 wiring specification. Nortel recommends
a maximum length of 100 meters for the cable segment.
• For 100BASE-TX operation, use Category 5 twisted-pair wiring: one pair
each for transmit and receive operations. The cable must comply with the
EIA 568 wiring specification. Nortel recommends a maximum length of 100
meters for the cable segment.
• For 10BASE-T operation, use Category 3, 4, or 5 twisted-pair wiring.
The following table provides the pinouts for the 1000BASE-T (1000 GT) Ethernet
