High-density DSP Module
The high-density DSP module (HD-DSP) can be installed to support a greater number of
voice calls or GSM TRXs.
•
A maximum of one HD DSP module can be installed on the SDM-9220 or SDM-
9230.
A single high-density DSP module supports 60, 80, 100 or 120 timeslots. Maximum 120
voice channels or 60 GSM TRXs per DSP.
NOTE:
High-density DSP modules require NetPerformer software version 10.3.5 R01
or higher. Earlier software versions will report a hardware problem and log an
error.

The high-density DSP module is intended for the SDM-
9210/9210GW, SDM-9220, SDM-9230, SDM-9606 and SDM-9620
only. DO NOT replace the high-density DSP module with a DSP
