Generalized Route Selection
Generalized Route Selection gives you the capability to select not only the optimal call routing based on the
dialed number, but also select the appropriate facility based on the type of call. Generalized Route Selection
enhances Automatic Route Selection and Automatic Alternate Routing by incorporating additional
parameters such as the type of call to be used in the decision of how a call is routed.

enhances Automatic Route Selection and Automatic Alternate Routing by incorporating additional
parameters such as the type of call to be used in the decision of how a call is routed.
Different types of calls require the use of different types of facilities. For example, high-speed data calls
must use digital facilities, whereas voice and voice-grade data calls can use either analog or digital facilities.
DEFINITY ProLogix Solutions uses Generalized Route Selection to differentiate between these and other
types of calls and route them on the appropriate trunks. Based on the call types and available trunk facilities,
voice and data calls may be routed over different trunk types or integrated on the same trunk group.
DEFINITY ProLogix Solutions also provides the capability to route calls based on the data format and the
need for restricted or unrestricted facilities.

In order to select the appropriate trunking facility for a call, DEFINITY ProLogix Solutions must know the
type of call being made. In order to do this, each originating facility such as a telephone or data module has
a bearer-capability class assigned. Some originating facilities, such as data modules, may have multiple
bearer- capability classes. Each trunk group in the routing pattern is assigned a list of allowed bearer-
capability classes. When a user makes a call, the system queries the originating facility for its bearer-
capability class and then tries to route the call on a trunk group with a bearer-capability class that matches
the bearer-capability class of the originating facility. If an exact match is not found, the system then tries to
find a trunk group with a compatible bearer-capability class.

Since the system automatically chooses the right trunk based on the system administration, DEFINITY
ProLogix Solutions’ dial plan can be independent of the type of call being dialed. This flexibility makes life
easier for your system users, who do not have to worry about dialing a different access number for different
call types.
