5.7 DSP Modules
On the SDM-9606 blade the DSP processors digitize, process and compress voice signals,
handle fax/modem emulation and, on units installed with the GSM A-bis/ter licensed
software option, perform A-bis/ter optimization and autodetection of GSM timeslot
subchannels.
• The SDM-9606 blade can be installed with either a synchronous low-density
DSP module (see next section) or a synchronous high-density DSP module (see
“High-density DSP Modules” on page 5-11
). 1 DSP socket is provided on the
blade.
Refer to
“Installing or Upgrading the DSP Modules” on page 4-4
for instructions on
installing the DSP modules. For ordering information, refer to
“Sales Contacts” on page 1-
11
.
NOTE:
To determine whether any DSP modules are currently installed on the SDM-
9606 blade, power up the unit as described on
“Powering Up the Unit” on
page 4-15
. The DSP type is displayed with the product banner that appears
after boot-up is complete.
5.7.1
High-density DSP Modules
The synchronous high-density DSP module (HD-DSP), which is the one type of DSP
supported on the SDM-9606 blade, can be installed on either the SDM-9606 blade to
support a greater number of GSM TRXs and voice calls.
A single synchronous high-density DSP module supports 60, 80, 100 or 120 timeslots.
Maximum 120 voice channels or 60 GSM TRXs per DSP.
CAUTION:
The synchronous high-density DSP module is intended
for the SDM-9210/9210GW, SDM-9220/9220GW, SDM-9230/
9230GW, SDM-9606 and SDM-9620 only.
DO NOT replace this
DSP module with a DSP intended for legacy NetPerformer
