Network Deployments and Interfaces
SCM in a CDMA2000 Data Network Deployment
Integrated CSCF / A-BG / HA
The SCM is designed to function within a CDMA2000 PDSN network. By combining the SCM with a carrier-class
Home Agent, a number of advantages emerge such as increased performance, distributed architecture, and high
availability. As shown in the figure below, the SCM supports a number of interfaces used to communicate with other
components in an IMS environment and supports the interface used to bridge the CDMA network.

Logical Network Interfaces (Reference Points)
Interfaces, used to support IMS in a CDMA network, can be defined within two categories: SIP and DIAMETER. The
SCM incorporates standards-based interfaces for both SIP and DIAMETER network architectures.
