Two basic deployment scenarios exist for the
routing and policy management.
- running exclusively on a server.
- co-hosted with other virtualized applications on a server.
Routing and Policy Management
The two basic configurations for routing and policy management are:
Centralized Sonus Policy Server (PSX)
The centralized PSX server combines call routing functionality with exceptional capacity of storing tens of millions of call routes in a single database. This SBC-Centralized PSX deployment distributes that routing intelligence to every PSX server in the network and simplifies the provisioning process.
Figure 1 describes SBC deployed with external PSX and an EMS.

Embedded Routing Engine (ERE)
ERE provides less routing and policy management functionality and is intended for smaller networks with no complex routing needs.
