RFC 1703 Radio Paging -- Technical Procedures October 1994
2. Naming, Addressing, and Routing
A radio pager is identified by a telephone number, e.g.,
+1 415 940 8776
where "+1" indicates the IDDD country code, and the remaining string
is a telephone number within that country.
In addition to a telephone number, a PIN may also be required to
uniquely identify a radio pager.
2.1. Addressing
This number is used to construct the address of a radio paging
server, which forms the recipient address for the message, e.g., one
of:
where "ATOM" is an RFC 822 atom [1], an opaque string for use in
recipient identification when communicating with the paging network,
and the domain-part is constructed by reversing the telephone number,
converting each digit to a domain-label, and being placed under
"tpc.int". (The telephone number must not include any international
access codes.)
Note that the mailbox syntax is purposefully restricted in the
interests of pragmatism. To paraphrase STD 11, RFC 822, an atom is
defined as:
atom = 1*atomchar
atomchar=
/
/ "!" / "#" / "$" / "%" / "&" / "'" / "*" / "+"
/ "-" / "/" / "=" / "?" / "^" / "_" / "`" / "{"
/ "|" / "}" / "~"
Finally, note that some Internet mail software (especially gateways
from outside the Internet) impose stringent limitations on the size
of a mailbox-string. Thus, originating user agents should take care
in limiting the local-part to no more than 70 or so characters.
