RJ-45 Cable Identification
Examine the sequence of colored wires to determine the type of RJ-45 cable:
•
Straight-through—The colored wires are in the same sequence at both ends of the cable.
•
Crossover—The first (far left) colored wire at one end of the cable is the third colored wire at the
other end of the cable.
Note
Both the standard straight-through and crossover Ethernet cables should be Category 5
UTP (RJ-45) cables. Cisco does not supply Category 5 UTP cables; these cables are
available commercially.
Voice Port Connectors
This section contains pinout and connection information for the three voice ports on the Cisco uBR924
router. The V1+V2 and V2 voice connectors are part of a dual-connector package. These are
symmetrical 6-pin connectors that use standard voice RJ-11 connectors and straight-through cables.
Note
To enable the voice ports, use a Cisco IOS Release 12.0(5)T or higher interim image that
supports VoIP and configure the router appropriately. See the Cisco uBR924 Software
Configuration Guide for more details.
Table B-2 lists the signals used on the voice ports.
