| Module ID | Name | Description |
|---|
| BRM | Bus/Bandwidth Manager | Bus/Bandwidth Manager is responsible for the allocation and activation of internal SonicBus resources for a call. |
| CAM | Call Accounting Model | The Call Accounting Model is responsible for receiving internal messages containing Call Accounting information and for passing this information along to its ultimate destination. |
| CPX | Confd Proxy | The CPX task acts as intermediary between Confd API and the underlying application. It is responsible for packaging notifications and for performing validation activities implemented by application call-backs (the reason the process is in the Application domain). |
| DNS | Domain Name System | The DnsClient is responsible for resolving names via a DNS query. It interfaces with SIPSG and the SIPS transaction layer, providing support for RFC3263 (Locating SIP servers). |
| DRM | DSP Resource Manager | The DSP Resource Manager is responsible for allocating and activating DSP based resources for a call. |
| DS | Directory Services Process | The Directory Services Process is the integration point for both internal (embedded PSX) and external policy-based routing. Its primary responsibility is to terminate the Diameter+ protocol and to convert back and forth between the internal representation of call control information (in the form of CPC structures) and the Diameter+ messages. |
| IM | Intercept Manager | The Intercept Manager is a component of the Lawful Intercept implementation |
| IPM | Policer Statistics Manager | The IPM process is responsible for collecting policer statistics (e.g. policed packets, top 10 offender list) at regular intervals from NP and providing the same information to performance manager when requested. |
| NRS | Node Routing Service | This service provides routing services for control and user IP traffic. |
| PATHCHECK | PathCheck process | The PathCheck process is responsible for periodically checking connectivity towards configured IP end points via ICMP ping packets. It reports any change in connectivity status to SIP. The SIP ARS (Address Reachability Service) adds the unreachable endpoints to an application-level Black List it maintains. |
| PFM | Performance Manager | The PFM task is responsible for gathering periodic performance statistics from applications and maintaining historical performance statistics in the CDB database |
| RTM | Redundancy Task Manager | The RTM process acts as a central coordination point for call data mirroring (done on a call-by-call basis as calls stabilize and terminate) and for synchronization (done when a standby card comes on line and assumes a role as a ready-standby). |
| XRM | Transport Resource Manager | This task is responsible for management and configuration of the NP layer. This includes the application-level activities involve with monitoring events in support of maintenance of NP-level Dynamic Black Lists. |
