These interfaces are described in the following sections.
Serial Interface (Cisco 633)
The serial interface uses 12-in-1 V.35 Data Terminal Equipment (DTE) serial connector. This interfface connects to a 5-in-1 V.35 Data Communications Equipment (DCE) serial port on a Cisco router.

LAN Interface
Ethernet Connector (Cisco 673, Cisco 678)
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 or full-duplex data rates on Category 3 (10 Mbps) or Category 5 (10/100 Mbps) twisted-pair wire up to 100 meters. The Ethernet connector is an RJ-45. Table A-3 shows the connector pinouts.

Management Interface
The management port uses an RJ-45 connector.
If you are not using a management cable ordered from Cisco, use the pinouts in Table A-5 for the DB-9 end of the serial cable used to connect the management port to the serial port of the PC.
Management Port Pinouts
Table A-5 shows the connector pinouts for the management port and the DB-9 end of the serial cable.
