Protocols and protocol settings are how PageGate software communicates with the recipient's wireless carrier.
PageGate uses the internet protocols: SNPP, WCTP and SMTP with an internet connection.
PageGate uses the modem protocols: TAP, FAX, GSM, UCP and TONE with dial-up modems.
PageGate uses TAP with a direct serial connection to an in-house paging terminal.
The recipient's wireless carrier determine what protocols they support, and what their protocol settings or host formats are. Carrier protocol settings at http://www.notepage.net/support.htm
