A-4Automatic Routing features
A
Generalized Route Selection
Provides voice and data call-routing capabilities. It is used to select not only the
least-cost routing, but also optimal routing over the appropriate facilities. It
enhances AAR and ARS by providing additional parameters in the routing
decision and maximizing the chance of using the right facility to route the call.
Also, if endpoint incompatibility exists, Generalized Route Selection provides a
conversion resource (such as a modem from a modem pool) to attempt to match
the right facility with the right endpoint.
Look-Ahead Routing
Provides an efficient way to use trunking facilities. It allows the system to continue
to try to reroute an outgoing ISDN-PRI call that is not completing. When the
system receives a cause value that indicates congestion, Look-Ahead Routing
tells the system what to do next. For each routing preference, you can indicate
whether the next routing preference should be attempted or if the current routing
preference should be attempted again.
NOTE:
This feature is not related to the Look-Ahead Interflow feature. The
Look-Ahead Interflow feature is not supported on DEFINITY BCS nor
GuestWorks.
Subnet Trunking
Subnet Trunking modifies the number dialed so an AAR or ARS call can route
over different trunk groups that may terminate in switches with different dial plans.
Subnet Trunking inserts digits, deletes digits, pauses, and/or waits for dial tone in
digit outpulsing, as required, so calls route as follows:
■ To or through a remote switch
■ Over Tie trunks to a private network switch
■ Over CO trunks to the serving CO.
Subnet Trunking is required on calls routing to or through a remote switch,
regardless of the call’s destination.
Time-of-Day Routing
Time-of-Day Routing allows you to select the most economical routing of ARS and
AAR calls based on the time of day and the day of the week a call is made. Up to
eight Time-of-Day routing plans may be administered, each scheduled to change
up to six times a day for each day in the week.
With Time-of-Day Routing, your company can take advantage of lower calling
rates during specific times. If your company has locations in different time zones,
you can maximize the use of your public or private network facilities by utilizing
