Look-ahead routing
Provides an efficient way to use trunking facilities. It allows you to continue to try
to reroute an outgoing ISDN-PRI call that is not completing. When
Communication Manager receives a cause value that indicates congestion,
Look-Ahead Routing tells the system what to do next. For each routing
preference, you can indicate if the next routing-preference should be attempted or
if the current routing-preference should be attempted again.
Node number routing
Allows you to specify the route pattern associated with each node in a private
network. It is a required capability for Extension Number Portability and is used
in conjunction with Automatic Route Selection, AAR and ARS Partitioning,
Private Networking, and Uniform Dial Plan. Uniform Dial Plan extensions can be
routed to a specified node using its associated pattern. Node Number Routing
allows a Uniform Dial Plan route pattern based on node numbers or on location
codes. On the AAR and ARS Digit Analysis Tables, you also can specify a Node
Number instead of a Route Pattern.
Time of day routing
Provides the most economical routing of ARS and AAR calls. This routing is
based on the time of day and day of the week that each call is made. Up to 8 TOD
routing plans may be administered, each scheduled to change up to 6 times a day
for each day in the week.
This allows you to take advantage of lower calling rates during specific times of
the day and week. In addition, companies with locations in different time zones
can use different locations that have lower rates at different times of the day or
week. This feature is also used to change patterns during the times an office is
closed in order to reduce or eliminate unauthorized calls.
Multiple location support
Multiple Location Support enables local user time, local ARS Public Analysis
Tables for local trunking, automatic Daylight Savings Time, and enhances shared
resource algorithms (touch tone receivers) when Remote Expansion Port
Networks (EPNs), ATM Port Networks, and Avaya Media Gateways are remoted
off of a central server at a different location.
