 Use change ars analysis to display the ARS Toll Analysis screen. Limit
long distance and international calls permitted by ARS trunks.
 Use change route-pattern to assign the appropriate FRL for public
network trunks in the routing pattern.
 Use change ars analysis to administer ARS Analysis Tables with at least
3- or 4-digit strings.
 Use change ars analysis to distinguish between 7- and 10-digit calls. Use
the prefix digit instead of the Min/Max fields for long distance calls.
 Use wild card characters with care.
 Prevent calls by not administering their numbers on the ARS Toll Analysis
screen. If the originating endpoint is assigned a toll-restricted COR, this
prevents TAC toll calls.
NOTE:
Whenever possible, TAC calls should be disallowed. See ‘‘Disable
Direct Access to Trunks’’ on page 4-38.
For DEFINITY G2.2:
 Do not turn on overlapped sending (default is off in G2.2, on in earlier
releases). To turn off overlapped sending, enter
PROC103 WORD1
FIELD14.
Overlapped sending bypasses digit checking.
 To force waiting for a TCM, the trunk group must be an intermachine trunk
group (
PROC103 WORD1 FIELD3=1 or 2) and ETN software must be
activated. A TCM will not be sent over an access tie trunk group no matter
how low the FRL is in
F2. However, a low FRL may be used to limit the
calling from the tie line, or to force a prompt for an authorization code.
 Mark each string and route with an FRL permission value using PROC314
WORD1 FIELD8
, and PROC318 WORD1 FIELD4.
 Use toll checking capabilities as shown:
— For WCR, use
PROC010 WORD3 FIELD22.
— For toll-free tables, use
PROC319 and PROC318 WORD1 FIELD6.
 If needed, define more detail in the numbering plan by using PROC314.
Use wild card digits and variable string lengths with care.
 Send a # after troublesome call types (0 +, 011 +, etc.). Use PROC321
WORD1 FIELD16.
NOTE:
Use PROC314 to route 0 and 00 calls to an attendant.
