* For every fax transmission call, both the originally assigned DSP resource,
plus the fax relay DSP resource, are consumed for the duration of the call.
Thus, the total remaining DSP connections is reduced by twice the number of
connections using fax mode service.
† Utilization of DSP resources for fax relay above 25% is not considered realis-
tic for most service provider environments. If this value exceeds 25%, then
the number of available DSP connections for pure voice mode calls is reduced
to less than 50% of connections available on the DSP2C module.
Table A-4 contains compliance specifications for the Multiservice Media
Gateway systems, and the I/O and server modules.
