Dsp Resource Advisor - Panasonic KX-NS500 Features Manual

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 (® 5.5.4.1 DSP
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:
Trunk using G.729 codec
Trunk using G.711 codec
Non-IP trunk (ISDN trunk, analogue trunk, etc.)
Extension using G.729 codec
Extension using G.711 codec
IP-CS extension using G.729 codec
IP-CS extension using G.711 codec
Unified Messaging
Two-way Recording
OGM

Conference trunk
*1 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.)
