PRI Facilities
Network Selection Tables
Dialed prefixes for selecting long-distance carriers are matched to entries in the
four Network Selection tables. Eight default tables are provided, specifying 10***
and 101****. The asterisks are wildcards that represent the various long-distance
carrier codes. (10*** is the current U.S. standard for specifying long-distance
carriers; 101**** is provided for future use.)
NOTE:
U.S. customers rarely need to program additional Network Selection tables
because long-distance carrier codes match 10*** or 101****.
