PRI Facilities

Outgoing Tables
3
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.
NOTES:
■
PRI tables that work with pools and ARS apply to Hybrid/PBX mode
only.
■
In Release 6.0 and later systems, when the PRI switch type is set for
Legend-PBX or Legend-NTWK to support a PRI tandem trunk, outgoing
tables do not affect outgoing calls for the PRI facility connected to the
slot specified by the Switch Type setting.
Network Selection Tables
3
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.)
