UTP Cable Specifications
To connect to the network, the NC7131 adapter uses the following cable for 1000Base-T
transmission.
Category 5 or better UTP twisted-pair
22-26 AWG, 100Ω @ 1 MHz
EIA/TIA 568a or EIA/TIA 568b
Using UTP Category 5 Cable in Gigabit Over Copper Installations
For Gigabit over copper installations, UTP Category 5 or better 1000Base-T cable must comply
with the IEEE 802.3ab 1000Base-T standard. For new installations, Category 5e (enhanced
Category 5) or better cable is recommended.
Gigabit Over Copper Cable Maximum Distances
Gigabit UTP 1000Base-T = 100 (328 feet) meters maximum
Troubleshooting Gigabit Over Copper Cabling
In a small number of cases, Category 5 cabling does not meet the performance parameters
specified by 1000Base-T. The most likely cause of the problem is in the connectors or patch
cable rather than in the horizontal cable itself. The following changes should help eliminate
these problems:
Replace the patch cord with a cord constructed from a Category 5e patch cable, which is
designed to comply with the return loss and ELFEXT parameters.
Reduce the number of connectors used in the link.
Reconfigure the cross-connect as an interconnect.
Reconnect some connectors in the link.
Replace the transition point or consolidation point connector with a Category 5e transition
point or consolidation point connector.
Replace the work area outlet connector with a Category 5e work area outlet connector.
Replace the interconnect with a Category 5e interconnect.
If the cabling still does not meet the standards, you may need to install Category 5e cable.
RJ-45 Pinouts and Crossover Function
The Ethernet standard also specifies that each segment implement a crossover function to
connect the transmitter of one device to the receiver of a device at the other end, and vice-versa.
The crossover function may be implemented internally at the hub/switch, or externally, through
the twisted-pair media.
10/100 Straight-Through Pinouts
If the crossover function is implemented internally, the port is labeled MDI-X (Medium
Dependent Interface –Crossover). When an MDI-X port is connected to an MDI port, the
twisted pair media should be wired straight-through using the physical pinouts indicated in
Table C-2.

Gigabit Over Copper Internal Straight-Through Pinouts
Unlike some connections in which the crossover function is implemented internally at the
hub/switch, the NC7131 adapter provides its own automatic crossover function. This means you
can wire twisted-pair media straight-through for adapter-to-hub/switch or adapter-to-adapter
connections, using the pinouts shown in Table C-4.
NOTE: To operate at Gigabit speeds, all four pairs of wires must be terminated within the RJ-45
connector.
