Modem Multiplexer

The modem multiplexer gives users access to a modem pool. The modem pool is the list of ModMux links with attached modems. When a call comes in that requires a modem, one is selected from the pool and dials out appropriately. The phone number to dial is configurable for incoming calls that need to be attached to modems.

Note: Round-robin dialing has been incorporated for ModMux links to minimize the demand placed on individual modems. Rather than always starting at the first available modem, the ModMux driver rotates through all available modems so that the first available one is not always the first to be dialed.
