Modem Pooling for the Cisco AS5200
Cisco IOS Release 11.2(10)P provides the modem pooling feature to the Cisco AS5200 access server. This feature chapter describes how to configure modem pooling. It also provides new command reference pages for new commands.
Modem pooling allows service providers to define, select, and use separate pools of modems within a single access server or router to provide different dial-in services. Modem allocation is based on the dialed number identification service (DNIS) and a predetermined number of modem ports based on DNIS.
There are a number of applications for using the call set up information, including DNIS/ANI, processing incoming call requests with CallerID, and selecting services to setup "automatically" for specified calls. These uses generally fall into two categories, those requiring allocation of a specific number of modems for a specific service, and those requiring allocation of specific physical modems.
In the following example, the pool-range command assigns modems 1 to 59 to the modem pool named accounts1.
The called-number 4085551212 max-conn 30 command assigns the called number 2000 to the accounts1 modem pool,
and it limits the total simultaneous connections for this number to 30.
The called-number 4084441212 max-conn 30 command assigns the called number 3000,
which is for a different customer, to the same accounts2 modem pool.
The total simultaneous connections for this called number is also set to 30.
This configuration guarantees a maximum of 30 modems to each customer
and protects each customer from unwanted modem calls overflowing in to their respective pools.
