Configuring Modem Pooling
Modems may be pooled so that specific ranges of the available modems are assigned to the various called
numbers handled by your system.
Any modem not assigned to a defined modem pool is assigned to the default modem pool.
Note
Restrictions
If you are using modem pooling in a CAS configuration, the following restrictions apply:
•
•
There must be at least one modem in the default modem pool for the modem pooling feature to work
for CAS calls. This is because every time a CAS call is made, a modem in the default pool is used
to collect the digits of the called number. Once the digits are collected, the call is forwarded to the
appropriate modem pool. One of the modems in that pool will be allocated for the call, and the
modem in the default pool will then be released. If there are no available modems in the default pool,
the call will not go through.
Whenever signaling type e&m-fgb is specified in the ds0-group command, it is necessary to
configure dtmf dnis as part of the signaling type.
Router(config)# ds0-group 1 timeslots 1-24 type e&m-fgb dtmf dnis
