Simple Network Paging Protocol

The Simple Network Paging Protocol (SNPP) is one of two recommended methods of connection to the American Messaging network for automated (server-to-server) connections, software clients, and customers requiring time critical delivery of messages. SNPP requires the use of Port 444 which is not typically open or allowed by all enterprise firewalls.

An additional benefit of the SNPP protocol is its ability to provide confirmed reception by the American Messaging messaging networks. Note, this is not a confirmation that the messaging device has received the message, rather this is confirmation that an American Messaging network has received the message. Because American Messaging cannot guarantee that a messaging device is within a coverage area, turned on and functioning properly, there is no guarantee that a message will be delivered to the device once it has been received by our network.

The following sections describe how to connect to the American Messaging messaging networks via SNPP. See below for messaging examples utilizing an SNPP connection.
