Take the following steps to remove a DSP module from the X6004.

1 Ensure the power is off and all cables are disconnected. Lay the X6004 upside down on 

a flat, dry surface. The DSP hatch is located on the base of the X6004.

2 Unscrew and remove the DSP hatch retaining screw.
3 Remove the DSP hatch cover.
4 Gently press the retaining arms away from the module, as shown in the figure. When 

both retaining arms are disengaged from the module, the module springs up to its angled 
position.

The X6004 automatically detects the number of DSP channels available for processing 
telephone conversations. The number of DSP channels is based on the DSP modules installed 
on the X6004. The X6004 automatically assigns DSP channels to service the analog phone 
connections (FXS ports) available on the X6004. It also automatically assigns DSP channels to 
the analog connections to the PSTN (FXO ports). The remaining DSP channels can be divided 
between the SIP connection via the X6004 and conference calls on the X6004.  
Consider the following when making decisions on how to assign the DSP channels on the 
X6004:
