Multiply the number of simultaneous faxes by two to determine the total number
of DSP channels required for fax calls. (Each fax call requires two DSP
channels.)
_______ x 2 = _______
Notes:
If the number of DSP channels required for fax calls is not divisible by four,
round up the number entered in step 1 to the next multiple of four. (Each
DSP device contains four channels.)
Always round up to a higher number.
2 Divide your Step 1 answer, the total number of DSP channels required for fax
calls, by four to determine the number of DSP devices required for fax calls.
