Product Description
Memotec Inc. 4-13
4.9 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
and fax/modem emulation.
4.9.1 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 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, upgrade to the high-
density DSP module (HD-DSP).
CAUTION:: The low-density DSP module is intended for the SDM-
9120, 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).
