IXO Protocol. This is a simple protocol frequently used for low-volume dial-up access to the paging terminal. 1200,7,e,1 is usually used. A simple checksum must be sent at the end of the message. 2. TAS Protocol. TAS stands for Telephone Answering Service. This is a real simple technique intended for users who access the paging terminal with a dumb terminal. The user is prompted for pager phone number and the alphanumberic message. 3. TNPP Protocol. This is the protocol that is most suited for interfacing a paging terminal with a customer's computer. A checksum calculation is required. The protocol provides for destination addressing, so that the paging terminal which receives a TNPP transaction from a customer may pass the transaction off to another paging terminal, possible at a faw-away location. TNPP stands for Telocator Network Protocol. Telocator is the name of a trade association for radio common carriers. At least a few Internet and uucp sites have mail addresses that will forward to alphanumeric paging systems. This is a good technique for automatically notifying a system administrator of critical problems etc. It also provides a convenient method for easily generating an alphanumeric page.
