Cisco IOS Software Features

Cisco IOS Software Features
There are two versions of software available for the Cisco MWR 1941-DC router. One version of
software is required for implementing the Cisco MWR 1941-DC router in an IP RAN; the other for
implementing the router in a Cell Site DCN.
The software features vary depending on the version of software running on the MWR 1941-DC router.

Software Features for the IP-RAN Implementation
The software required for implementing the MWR 1941-DC router in an IP-RAN consists of two
components: Cisco IOS software running on the MIPs-based route processor portion of the
MWR 1941-DC router hardware, and microcode running on the Cisco network processor, also known as
"Parallel eXpress Forwarding (PXF)." When deployed in an IP-RAN, the MWR 1941-DC router is
customized for performance, high availability, quality of service, and link efficiency.
Cisco IOS software functions added to the MWR 1941-DC router for the IP-RAN implementation

Redundancy logic—For monitoring Hot Standby Routing 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 MWR 1941-DC router.
