5.5.4.2 DSP Resource Advisor
Description
Web Maintenance Console provides a tool for calculating the number of resources required for a given set of
operating conditions. The Web Maintenance Console user provides information such as the number of ports
for a given resource (e.g., 16 extension ports using the G.729 codec) and the expected usage load (e.g., 50%
busy), and the resource advisor calculates the number of DSP resources required to meet those conditions.
This tool can be used in offline mode to simulate various PBX configurations and usage cases to help determine
the size of DSP card required.
This tool will also recommend which and how many resources to reserve for various features (
®
Resource Reservation). The recommended settings can be applied immediately from the resource advisor
tool.
The resource usage can be calculated using the following types of services and features:
Service/Feature
DSP Resources per Unit
Trunk using G.729 codec
2.2
Trunk using G.711 codec
1
Non-IP trunk (ISDN trunk, analogue trunk, etc.)

Extension using G.729 codec

The DSP costs of the extensions/trunks involved in the operation are not included in the per-unit DSP resource count.
*2
Two-way Recording also requires a conference trunk. For an example of the required DSP resources, see 5.5.4 DSP Resource
Usage.
Example 1: Small Office
In a small office (e.g., 32 employees), the necessary number of trunks and extensions is likely to be relatively
small. In addition, the expected load on the system will also be small.
(For clarity, unused services are not included in the table.)
