To the Administrator regarding account passwords

To avoid unauthorised access and possible abuse of the Control Box, keep the passwords
secret, and be aware of the importance of the passwords, and the possible dangers if they
become known to others.

The Control Box has no passwords set initially. For security, select a secure password as soon
as the Control Box is installed at the site.

4.4.2 DSP Resource Usage
Description
To digitally process audio signals, such as a telephone call, the Control Box must use a certain number of
DSP (Digital Signal Processing) resources. DSP resources are provided by the DSP card installed in the
Control Box. Since there are a limited number of DSP resources, no further operations (e.g., telephone
calls) can be performed if all resources are being used.
The following list shows some of the basic operations that require DSP resources.
•
SIP extension call
•
Accessing the Unified Messaging system (including recording calls)
For SIP extension calls, the number of required resources differs depending on the codec (G.711 or G.729)
used.
Examples of DSP resource usage
Fundamentally, the number of resources required for a given situation is the sum of the resources required
for each individual operation. The following examples illustrate DSP resource usage in various situations.
