PDN Interfaces

PDN interface provide connectivity between the PDSN and/or HA to packet data networks such as the Internet or a

corporate intranet.

AAA Interfaces

Using the LAN ports located on the Switch Processor I/O (SPIO) and Ethernet line cards, these interfaces carry AAA

messages to and from RADIUS accounting and authentication servers. The SPIO supports RADIUS-capable

management interfaces using either copper or fiber Ethernet connectivity through two auto-sensing 10/100/1000 Mbps

Ethernet interfaces or two SFP optical gigabit Ethernet interfaces. User-based RADIUS messaging is transported using

the Ethernet line cards.

While most carriers will configure separate AAA interfaces to allow for out-of-band RADIUS messaging for system

administrative users and other operations personnel, it is possible to use a single AAA interface hosted on the Ethernet

line cards to support a single RADIUS server that supports both management users and network users.

highest performance. The local context should not be used for service subscriber AAA functions.

Co-Located Deployments

An advantage of the system is its ability to support both high-density HA and PDSN/FA configurations within the same

chassis. The economies of scale presented in this configuration example provide for both improved session handling and

reduced cost in deploying a CDMA2000 data network.

The following figure depicts a sample co-located deployment.

Subscriber AAA interfaces should always be configured using Ethernet line card interfaces for the
