Chapter 11 DSP Management
DSP Management
The X2002 automatically detects the number of DSP channels available for
processing telephone conversations. The number of available DSP channels is
based on the DSP modules installed on the X2002.
The X2002 automatically assigns DSP channels to service the analog phone
connections (FXS ports) available on the X2002. It also automatically assigns DSP
channels to the analog connections to the PSTN (FXO ports).
The remaining DSP channels is are shared among all services which require DSP
resources on the X2002.
11.1.3 Before You Begin
Consider the following when making decisions on purchasing additional DSP
modules or assigning the DSP channels on the X2002:
• A typical conversation uses two channels.
• A conference call uses one channel per participant.
• Unassigned DSP channels are shared among all services which require DSP
resources.
