Cisco 2621 Modular Access Routers
BRI, and integrated CSU/DSU options for primary and backup WAN connectivity, while available
network modules support multi-service voice/data/fax integration, departmental dial concentration, and
high-density serial options. The AIM slot supports integration of advanced services such as
hardware-assisted data compression and encryption. All Cisco 2600 series routers include an auxiliary
port supporting 115Kbps Dial On Demand Routing, ideal for back-up WAN connectivity.
The physical interfaces include power plug for the power supply and a power switch. The router has two
Fast Ethernet (10/100 RJ-45) connectors for data transfers in and out. The module also has two other
RJ-45 connectors on the back panel for a console terminal for local system access and an auxiliary port
for remote system access or dial backup using a modem. The 10/100Base-T LAN ports have
Link/Activity, 10/100Mbps, and half/full duplex LEDs.
