I/Page provides connectivity between the dispatching environment and a third-party paging controller over a serial RS-232 connection (direct or dialup) using the TNPP, TAP, SNPP level 1, and SMPP one-direction protocol. This product functions as an extension to the dispatcher functionality. Alphanumeric messages and/or tone pages can be transmitted from the dispatch environment over the third-party paging terminal to the destination-paging unit. I/Page must be customized to adapt to the available third-party paging terminal.
