5.8 DSP Modules
High density, high performance DSP processors digitize, process and compress voice
signals on the NetPerformer unit. The DSP processors handle voice compression software,
fax/modem emulation, autodetection of GSM timeslot subchannels and A-bis/ter
optimization.
5.8.1
DSP-160 Module
A single low-density module (DSP-160) has 1, 2, 3, 5 or 6 DSP processors. Each DSP
processor supports 5 digital timeslots. Maximum 30 voice channels or 15 GSM TRXs per
DSP module.
NOTE:
One low-density onboard DSP processor is provided with each FXS, FXO
and E&M interface card to support analog voice calls. A maximum of 8
analog voice channels is permitted.
NOTE:
If you require support of more than 30 voice channels or 15 TRXs, upgrade to
the high-density DSP module (HD-DSP).
CAUTION:
:
The low-density DSP module is intended for the SDM-
9210/9210GW, SDM-9220 and SDM-9230 only. DO NOT replace the
low-density DSP module with a DSP intended for legacy
NetPerformer products (SDM-9360, SDM-9380 and SDM-9585).
