DSP Notes
Voice mail:
• Program the additional voice mail ports, then add the DSP MMCs if
necessary (for the MXe Server, AX, and MXe, you need to add DSP
resources only if you need compression or FAX Relay (T.38)).
• With Release 5.0, voice mail ports support G.729a compression.
When you increase the number of ports you may also have to add
DSPs to handle the increased demand for compression.
Compression:
• You must purchase compression licenses before adding DSP
modules for compression.
• Upgrading to 64 compression channels requires a minimum 300 MHz
controller (see “Migrate SX-2000 PBX Hardware”, page 404).
Telecom:
If the system needs compression channels and/or 30 voice mail ports
and/or increased telephony resources to support more TDM devices, then
additional DSPs may be necessary. (see “Hardware Part Numbers” on
page 371 for the part numbers of the DSP modules).
