Cisco IOS Software Features

There is one version of software available for the Cisco 3825 router. This version of the software is required for implementing the Cisco 3825 router in a Radio Access Network-Optimization (RAN-O) configuration.

Software features for the RAN-O Implementation

The software required for implementing the Cisco 3825 router consists the Cisco IOS software running on the MIPs-based portion of the Cisco 3825 router hardware.

Cisco IOS software functions added to the Cisco 3825 router for the RAN-O implementation include:

•Redundancy logic—For monitoring Hot Standby Router Protocol (HSRP) information to determine the active and standby router and control T1 termination.

•Failover logic—To force a switchover for hardware failures or an over-temperature condition.

•Relay control—To open and close the T1/E1 interfaces on the active and standby routers.

•Diagnostic functions—To monitor the “health” of the standby Cisco 3825 router.
