Wild-Card Notation in ROUTE and APPL X.121

Addresses and Numeric User Identifiers

This address matches all X121-ADDR attributes that begin with 493.

Similarly, this address matches all NUMERIC-USER-IDENTIFIER attributes that begin

with 7752:

NUMERIC-USER-IDENTIFIER 7752*

The following are not valid partially wild-carded name elements, because the asterisk is

not at the end of the string:

NUMERIC-USER-IDENTIFIER 4*93

X121-ADDR *493

Here is a description of how OSI/MHS routes an incoming message to a partially

wildcarded address. Assume that the local subsystem includes a ROUTE object whose

NUMERIC-USER-IDENTIFIER O/R attribute is partially wildcarded.

If there is a numeric user identifier element within the message’s recipient O/R

name, and

if the numeric user identifier in the message's recipient O/R name matches the first

part of a partially specified numeric user identifier in the ROUTE object, and

if the message’s recipient O/R name meets the routing criteria defined for that

ROUTE, and

if there are no ROUTEs, APPLs or DLISTs that contain a precise match for the

routing criteria,

then the message can be routed to the partially specified ROUTE.

Table 1-2 contains examples of successful and unsuccessful routing:

Full Wildcarding

OSI/MHS also supports full wild-carding of X.121 addresses and numeric user

identifier names. Full wild-carding allows an X.121 address to match any valid

incoming X.121 address, or any numeric user identifier to match any valid incoming

user identifier.

Note. The X121-ADDR string is 1 to 15 numeric characters long; the NUMERIC-USER-

IDENTIFIER string is 1 to 32 numeric characters long.
