Cabling—RJ-45 connector for the 10/100baseTX interface and either RJ-45 connectors for the ISDN/PRI with
integrated CSUs, or DB-15s for non-CSU and E1 versions. The following table provides cabling product numbers
and descriptions:
LEDs—Network Module status indicator, FDX indicator, 10/100-Mbps indicator, link indicator, and collision
indicator in reference to the 10/100baseTX, Carrier Detect, Remote Alarm, Local Alarm, and Loop indicators
for T1/E1.
Network Interfaces—One RJ-45 10/100baseTX interface and either one or two RJ-45 for integrated CSU versions
or one or two DB-15s for the T1/E1 connections.
Ethernet Connectivity
Five available network modules offer four-port, single-port, and dual-port Ethernet LAN connectivity in the
Cisco 3600 series for maximum configuration flexibility as a multifunction platform.
Mixed Media Network Modules
The mixed-media network modules allow administrators to configure an Ethernet port (or two ports) with additional
WAN connections using the WAN interface cards on the same module to conserve slot space.
For example, as part of a multifunction solution, a Cisco 3620 platform with a 2E2W can support two Ethernet
LANs, together with two serial/ISDN backhaul lines, andstill allow multiple serial or ISDN in the same chassis. This
solution outperforms the competition in industry-leading price/performance.
Four-Port Ethernet Module
The four-port Ethernet network module provides industry-leading price/performance, enabling high-density Ethernet
connectivity. The four-port Ethernet network module offers a lower price point for multifunction solutions that
require higher-density Ethernet than the mixed-media network modules.
An example is a Cisco 3640 platform with a four-port Ethernet network module, 16-port ISDN Basic Rate Interface
(BRI), and a 32-port Asynchronous serial network module.
This configuration integrates branch office routing requirements with four Ethernet LAN segments and the mixed
dial requirements of sync/async serial lines and ISDN.
