The following diagram shows a high-level view of the USRM architecture. The top
row shows the plug-in applications, while the bottom row shows the various
interfaces. As shown, the USRM is configured as an integrated unit supporting VOD
and SDV.

The USRM can operate in conjunction with the DNCS. In such systems,
responsibilities for real-time session and resource management (SRM) may be
assigned to USRMs by "relocating" the DNCS's SRM into the USRM platform. Such
session and resource management may include VOD and SDV. In these systems, the
USRM is provisioned by the DNCS. In non-DNCS systems, the USRM is
configurable independently of the DNCS using its Web interface.

A key design goal of the modular USRM design was service velocity. The software
design and modular nature of the USRM helps to achieve this. New applications and
interfaces may be developed and installed, in some cases at run-time, without
service interruption and often without requiring any changes on the DNCS. The new
capabilities inherit the platform capabilities, such as high-availability, Web interface
and the ability to interconnect to many different devices.

The USRM is configurable with various combinations of the applications and
interfaces shown in the previous diagram to meet system needs.
