The GNS can be configured to use up to 10 communications ports within a multiplexed modem pool. If one communications port is busy, the notification message will be forwarded on to the next free port within the modem pool. Any generic modem can be used. For specific modem configuration requirements, consult the manufacturer’s manuals.
Alphanumeric paging uses the TAPI protocol. When an alphanumeric page is sent, the call is sent to the alphanumeric paging company’s modem and then sent out to the pager. The GNS configuration file contains a keyword (ALPHANUMERIC_PHONE) that defines the default modem phone number. If you work with more than one alphanumeric paging company, the notification record in the GNS can override this parameter.
The following keywords must be configured to enable alphanumeric and numeric paging notifications. See the Paging (Numeric and Alphanumeric) Keywords for more information.
