Assigning bandwidth for typical IP fax usage
After the fax server has control of a digital modem, it dials the call on any available channel
unless the fax server configuration specifies a trunk-group number. In that case, the fax server
uses an available channel within the specified trunk group. If no channels in that trunk group
are available, the MAX unit returns a Trunk Group Not Available code to the fax server, which
tries the call again later.
For example, the following commands configure the system to use 2-digit trunk groups, and
assign an entire a T1 line to trunk group 5. (Fewer than 24 channels can be assigned to a trunk
group if appropriate.) If the fax server configuration also specifies 2-digit trunk groups and
trunk group 5, the following channels are available for IP fax usage.

Specifies
Enable/disable the use of trunk groups in the MAX. With the
default setting of no, the Num Trunk Digits and
Trunk-Group settings do not apply. With the yes setting, all
channels must be assigned trunk-group numbers.
Number of digits to allow for trunk groups. Currently, the IP
fax server supports 2-digit trunk groups, but the
trunk-group-number specification must be within the range of
2 to 9. The MAX must agree with the fax server about the
number of digits in a trunk-group number, or telephone num-
bers are not parsed correctly and calls fail.
Total number of dial-out calls that the MAX can place at the
same time.
Assignment of a channel to a trunk group, making it available
for outbound calls. Dial numbers for connections can then be
directed to specific channels by specifying the trunk group as
a single-digit dialing prefix to the far-end phone number.
