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.
Note
Any modem not assigned to a defined modem pool is assigned to the default modem pool.
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
Cisco IOS Release 12.4(9)T, 12.4(11)XW, and 12.4(20)T
11
Cisco PVDM2-12DM, PVDM2-24DM, and PVDM2-36DM Digital Modem Packet Voice Data Modules
How to Configure Digital Modem PVDM2s
When dtmf dnis is part of the ds0-group command, functions in CSM V12 firmware collect the
digits of the called number and match them to the called number in the appropriate modem pool,
putting the call through. If dtmf dnis is not part of the ds0-group command, these functions are
never activated and no called number match is made, resulting in a default pool modem being used
instead of a modem from the correct pool. The call will not go through in such a case.
SUMMARY STEPS

modem-pool name
2.
pool-range modem1-modemN
3.
called-number number max-conn number

Example:
Router(config)# pool-range 386-388
Step 3
called-number number max-conn number
Example:
Router(config)# called-number 5557528 max-conn 3
Specifies the range of modem numbers assigned to
the modem pool.
If the modem pool consists of a single modem, the
modem number of that modem is entered by itself, as
in pool-range 386, for example.
Specifies a called number assigned to the modem
pool. The variable max-conn specifies the
maximum number of simultaneous calls that may be
connected to the called number.
Configuring Modem Recovery
The modem recovery feature is present to detect bad modems and mark them, saving the user from the
task of doing this manually. If there are spare modems in the platform, this process could prevent callers
from getting dead air or busy signals.
The modem recovery feature uses two CLI commands. The modem recovery threshold command sets
the number of consecutive failures that a modem must experience before the recovery process is
performed. The modem recovery action command defines the action taken on the failed modem. The
recovery action will either be “disable”, where the IOS will mark the modem bad, or will be “none”,
where nothing will happen to the modem and the threshold counter will be reset.
A modem failure is defined as any time that the CSM assigns a call to a modem, but that modem does
not reach steady state. The call would be classed as a “no answer” or as a trainup failure.
To configure modem recovery, enter the following commands in global configuration mode.
SUMMARY STEPS
1.
modem recovery threshold failed-calls

DETAILED STEPS
Step 1
Command or Action
Purpose
modem recovery threshold failed-calls
Specifies the number of consecutive failure that
must occur on a modem before modem recovery
action takes place.
Example:
Step 2
Router(config)# modem recovery threshold 10
The range is 0 to 1000. The default value is 30.
modem recovery action {disable | none}
Specifies the action to be taken on a modem when its
modem recovery threshold is reached. disable will
cause the IOS to mark the modem as bad and remove
it from service. none will reset the threshold counter
for the modem, but will do nothing else. The modem
stays in service.
Example:
Router(config)# modem action recovery disable
Example
The following configuration will result in a modem being marked bad by the IOS after 8 consecutive
failures.
router(config)# modem recovery threshold 8
router(config)# modem recovery action disable
Loading Modem Firmware

module has two ports. If the network module installed in your router has two ports, you need to do the
following procedure on both ports.

interface.
Example:
See the Cisco IOS Release 12.4 Master Commands List for
a complete listing of supported signaling methods.
Router(config)# isdn switch-type primary-qsig
Step 2
pri-group timeslots timeslot-range
Example:
Router(config)# pri-group timeslots 1-24
Specifies an ISDN PRI group on a channelized T1 or E1
controller.
timeslot-range specifies the time slots that are included in
the PRI group. For T1 ports, time slots range from 1 to 24.
For E1 ports, time slots range from 1 to 31.
Configuring the ISDN D-Channel Serial Interface
When you configure ISDN PRI on a channelized E1 or channelized T1 controller, you create a
corresponding D-channel serial interface used to carry signaling messages for that PRI group. For E1
modules, channel 15 is the D-channel. For T1 modules, channel 23 is the D-channel. You must configure
this signaling interface in order to receive incoming and modem calls.
The PRI network modules and interface cards for your router can have either one or two ports; therefore
you might have multiple D-channels to configure.
To configure the ISDN D-channel serial interface for E1 or T1 controllers, perform the following tasks,
beginning in global configuration mode:
