PageGate can support up to 16 simultaneous dialers. PageGate comes with a single dialer by default. Additional dialers can be purchased separately. Each dialer has the option to be a direct connection, connected to a modem, or connected to the internet. Each dialer can also be dedicated to a single carrier if desired. The dialers are intelligent and will try to deliver messages in the most efficient manner possible. If more than one dialer is owned, a new dialer will start for each carrier that has messages pending for it. Once a carrier connection is made, all pending messages for that carrier will be delivered. If any dialers are still idle, the 'Dialer Threshold' value will be checked to see if any carrier has more pending messages than this value. If so, an additional dialer will connect to the same carrier to assist in message delivery.
Please note that adding additional dialers may be desirable for not only performance reasons, but also from a redundancy standpoint. If more than one dialer is used with PageGate, and there is a failure on one dialer (failure with phone line, modem, cabling, serial ports, etc.), PageGate will continue to operate on the remaining dialers, ensuring that there is no outage of paging services.
If only an internet connection is to be used with a dialer, you can set the serial port to 0. If any other port number is used, the dialer can deliver messages both out the serial port (usually via modem), and out over the internet.
