Configuring Modem Pooling
Modem pooling allows you to control which modem a call connects to, on the basis of dialed number
identification service (DNIS). When modem pooling is not used, incoming and outgoing calls are
arbitrarily assigned to modems. For example, consider a Cisco AS5300 access server loaded with a
4-port ISDN PRI card. After an analog modem call comes into the first PRI trunk, the call is greeted by
a general pool of B channels and a general pool of modems. Any B channel can be connected to any
modem in the access server. A random assignment takes place. Modem resources cannot be controlled.
Modem pooling assigns physical modems to a single DNIS. It enables you to create pools of physical
modems in one access server, assign a unique DNIS to each modem pool, and set maximum simultaneous
connect limits.
This feature is used for physically partitioning or virtually partitioning modems inside one network
access server.
