4.3 Installing or Upgrading the DSP Module
Follow the procedure in this section for both installation and upgrade of a DSP module on
the SDM-9220/9230.
CAUTION:
The low-density (DSP-160) and high-density (HD) DSP modules are
intended for the SDM-9220 and SDM-9230 only.
DO NOT
replace the DSP-160 or HD DSP module with a DSP module intended
for the SDM-9360, SDM-9380 or SDM-9585.
Likewise, do not install a DSP-160 or HD DSP module in an SDM-9360, SDM-
9380 or SDM-9585 unit.
NOTE:
The synchronous HD DSP module used for GSM applications requires Net-
Performer software version 10.2.3 R08 or higher. The synchronous low-den-
sity DSP module for GSM requires version 10.3.5 R02 or higher. Earlier
software versions will report a hardware problem and log an error.
