Single-Port Ethernet Module
A single-port Ethernet network module allows customers to choose a configuration at the right price for their specific
applications.
For example, as part of a multifunction solution, a Cisco 3640 platform with a single Ethernet connection to a LAN
backbone can also support either six PRI connections to aggregate ISDN lines, or 24 synchronous/asynchronous
ports. This solution handily outperforms the competition in industry-leading price/performance.
Cabling—RJ-45 connector
LEDs—Network module status indicator, status LEDs including send/receive, half/full duplex, and LAN speed
indication
Network interfaces—One or four 10BaseT ports
