Outgoing Tables; Network Selection Tables - AT&T MERLIN LEGEND Release 3.0 Programming Summary Manual

Outgoing Tables

Outgoing Tables
PRI provides tables that work in conjunction with personal lines, pools, and
ARS tables to route calls. The following tables specify services for outgoing
calls:
Call-by-Call. Selects an outgoing service, based on routing digits and
the bearer capability (voice, data, or both) of the calling extension. It
allows a single group of B-channels to carry a variety of services, such
as ACCUNET, SDN, and Megacom WATS.
Network Selection. Selects a long-distance carrier. Calls that match
Network Selection tables can be routed to a specific service by the
Call-by-Call tables.
Special Services. Selects services such as international dialing and
operator assistance. Calls that match these tables are not routed by
the Call-by-Call tables.
NOTE:
PRI tables that work with pools and ARS apply to Hybrid/PBX mode only.

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****.
