Increase Network Capacity and Reliability
To provide media-rich applications effectively, mobile service operators
are implementing third-generation Evolution-Data Optimized (EV-DO) services.
These services split high-speed data and voice services onto different
carriers. Often EV-DO traffic is delivered to the radio network controller
(RNC) site through channelized DS-3, OC-3/STM-1, OC-12/STM-4, Fast Ethernet,
or Gigabit Ethernet. The EV-DO RNC requires the combined traffic to be
delivered over Gigabit Ethernet. The Cisco aggregation node provides
this grooming capability.
The Cisco solution is a fully redundant, carrier-class, high-availability
aggregation solution with channelized optical connectivity, automatic protection
switching, and full quality of service.
Cisco provides a one-box EV-DO aggregation solution that works with systems
from all major RAN vendors.
Cisco EV-DO aggregation is deployed extensively in the world’s largest
Code Division Multiple Access (CDMA) networks, providing:
- High quality of service
- Stateful failover
- Proven 99.999 percent availability
- In-service software upgrade
- Metro Ethernet for alternative backhaul
