The number of voice channels needed is the number of voice capable station cards plus the number of
telco trunks that will be simultaneously playing or recording voice. There does not have to be an Voice
Channel for every audio path on the system. In smaller systems, (under 12 audio paths) a 1.5 to 1 ratio of
audio paths to Voice Channels usually is sufficient. In larger systems a 2 to 1 ratio is sufficient. If the
number determined in section 4.1.1.1 is less than 12, divide that number by 1.5 and record the result
here. If the number determined in section 4.1.1.1 is greater than 12, divide that number by 2 and record
the result here.
4.1.2 Voice Controller Ordering
The Voice Controller card (950-9061) comes with four audio paths as standard equipment. If more audio
paths are required, the Voice Controller needs to be equipped with the Additional Voice Channels (950-
9063) option. This option adds four audio paths to the Voice Controller’s capacity, to a maximum of
sixteen audio paths (one Voice Controller plus three Additional Voice Channels options). A second card
with Additional Voice Channels can be added for a total of 32 ADPCM Voice Channels. All 16 channels
must be populated on the first card before a second card can be used. Order the number of cards and
additional voice channels necessary to get the number of voice channels specified above.
