This RFC suggests a simple way for delivering both alphanumeric and numeric pages (one-way) to radio paging terminals. Gateways supporting this protocol, as well as SMTP, have been in use for several months in one nationwide paging firm. One other paging firm is in the process of adopting it.

This RFC suggests a simple way for delivering both alphanumeric and
numeric pages (one-way) to radio paging terminals. Gateways
supporting this protocol, as well as SMTP, have been in use for
several months in one nationwide paging firm. One other paging firm
is in the process of adopting it.
Earlier versions of this specification were reviewed by IESG members
and the IETF's "822 Extensions" Working Group. They preferred an
alternate strategy, as discussed under "Relationship to Other IETF
Beepers are as much a part of computer nerdom as X-terminals
(perhaps, unfortunately, more). The intent of Simple Network Paging
Protocol (SNPP) is to provide a standard whereby pages can be
delivered to individual paging terminals. The most obvious benefit
is the elimination of the need for modems to produce alphanumeric
pages, and the added ease of delivery of pages to terminals in other
cities or countries. Additionally, automatic page delivery should be
somewhat more simplified.
2. System Philosophy
Radio paging is somewhat taken for granted, because of the wide
availability and wide use of paging products. However, the actual
delivery of the page, and the process used (especially in wider area
paging) is somewhat complicated. When a user initiates a page, by
dialing a number on a telephone, or entering an alphanumeric page
through some input device, the page must ultimately be delivered to
some paging terminal, somewhere. In most cases, this delivery is
made using TAP (Telocator Alphanumeric input Protocol, also known as
IXO). This protocol can be a somewhat convoluted, and complicated
protocol using older style ASCII control characters and a non-
standard checksumming routine to assist in validating the data. One
note: even though the TAP protocol allows for a password for sending
simple pages, they are rarely used (especially in commercial
markets), and therefore support for them has not been implemented in
this version of the protocol.
Even though TAP is widely used throughout the industry, there are
plans on the table to move to a more flexible ...
