PDSN

The PDSN needs to have connectivity with the following major nodes:
■ CDMA radio network
■ Either a public data network, private data network, or both
■ AAA server
■ DHCP server
■ Service creation platform that contains the configuration, policy,
profile, sub-provisioning, and monitoring capability
The PDSN is usually connected to the packet data network via an
OC3/STM1 or 100baseT connection. The choice of which bandwidth to utilize
is determined by not only the proximity of the PDSN to the BSC, but
also on traffic requirements. In summary, the PDSN design is based on
many factors including the following basic issues:
■ Number of BSC locations
■ Access type supported (simple IP, mobile IP, and so on)
■ Connectivity between nodes
■ Network performance requirements
