The following ports are located on the backside of the Cisco 673.

ENET---LAN Interface (connects to the yellow cable)
MGMT---Management Interface (connects to a light blue cable)
WALL---SDSL Port Interface (connects to a lavender cable)
PWR---Power Connector

The LAN interface uses an Ethernet port that conforms to the IEEE 802.3 and 802.3u protocols and supports 10 or 100 MBps half-duplex data rates on category 3 (10 MBps) or category 5 (100 MBps) twisted-pair wire at a distance of up to 100 meters or less. The Ethernet connector is an RJ-45. Table A-1 shows the connector pinouts.
