Prevent After-Hours Calling Using Time of Day
Routing or Alternate FRLs
You can regulate the days of the week and specific times that outgoing calls can
be made. Depending on the time of day and day of the week, calls can be blocked
or routed to the least-costly facility available. Since late evenings and weekends
are particularly vulnerable times for toll hacking, set up separate plans with the
most restrictive plan reserved for evenings and weekends. If you do not want toll
calls made after hours, block them during those times. You can also use Call
Vectoring to route to different trunk groups; for example, after hours you may want
only 50 trunks available instead of 200.
For DEFINITY ECS and DEFINITY G1 and G3:
 Use change ars analysis partition x to define an ARS Analysis Table to
be used for after-hours calling.
 Use change time-of-day y to select and define a Time of Day plan.
 Administer the times you want to offer Remote Access and the times you
do not.
 Use change cor xx to assign the Time of Day plan to the COR for barrier
codes or authorization codes.
For DEFINITY G3r:
 Use change attendant to display the Attendant screen.
 In the Feature Button Assignment field, enter alt-frl to administer an
alternate FRL button on the attendant console. This button is used to
activate lower FRLs after business hours so the calling area is limited.
 Use change alternate frl to assign the alternate FRL that will replace each
original FRL when the attendant activates the feature.
For DEFINITY G2 and System 85:
 There are three Time of Day plans (seven for G2.2). Use PROC316
WORD1
to set day, hour and minute, and plan number.
 When using WCR, enter PROC311 to separate toll and non-toll numbers
into different routing indices. Use
PROC314 for tenant services to separate
toll and non-toll numbers into different routing indices.
 Use PROC311, PROC316, and PROC317 to shut down toll routes outside
of business hours.
 Use PROC286 WORD1 FIELD5-12 to lower FRLs after hours to make
them more restrictive.
 Enter PROC203 WORD1 Button Type 19 to set the alternate FRL button
on the attendant console. This allows attendants to manually change to
alternate FRLs.
