DSP Management
11.1 Overview
This chapter shows you how to install additional Digital Signal Processing (DSP)
modules in the X6004 and how to manage the X6004’s DSP resources.
The X6004 uses DSP modules to convert analog audio to digital signals, and vice
versa.
The X6004 is equipped with an onboard DSP module and two extensible DSP slots
by default. You can upgrade the existing DSP module with one or two that can
process more channels. You can also install a second module to increase the
number of calls the X6004 can handle simultaneously. See the product
specification in
for details about the X6004’s DSP
modules.
This chapter shows you how to install and uninstall additional DSP modules in the
X6004. It also discusses how to manage the DSP resources on the X6004.

The following terms and concepts may help you as you read through the chapter.
DSP Channels
DSP modules are classified by the number of channels they are capable of
processing. A normal phone conversation takes up to two channels, since the
X6004 must encode the outgoing analog audio while simultaneously decoding the
incoming digital audio.
