Digital Signal Processing
There is one general-purpose Digital Signal Processor (DSP) located on the ISC1 which is
shared between the VAM and the Fault Monitor Module.
The DSP on the ISC1 also contains resources for a V.34 modem, FAX tone detections, DTMF
tone generators, Caller ID detectors/generators, VoIP codecs, media channels and conferencing
channels.
Important: The DSP on the ISC1 contains sufficient DSP resources to support a basic PBX
with approximately 32 users, however this does not guarantee adequate DSP resources for all
32-user applications. Your specific applications may require a Media Resource Module (MRM)
to provide additional resources. (See Chapter 7 for more about MRMs.)
You must allocate an appropriate number of resources to cover your system demand. If you
under-allocate resources, calls may be lost or not handled as expected. To determine whether
you have adequate resources on your Wave system to support your required applications, use
the Wave Resource Management Advisor, which calculates requirements for most resource
types based on your answers to a series of questions, and on the cards, modules, and Wave
licenses installed on your Wave Server. For details about how to use the Resource Manager
Advisor, see “Managing Wave system resources” in Chapter 23 in the
Wave Global
Administrator Guide .
