Route A Route is a set of pre-programmed dialling rules that can include
access codes to be used to place a telephone call over a particular
service or carrier. A Route is chosen by matching dialled digits with a
template in the Search Tables. If a Route in the EuroRoute is compared
to a Route (trunk group) in a PSTN or a PABX, it may be helpful to
think of a EuroRoute Route as a “Virtual Route”.
Search Tables The Search Tables are a set of templates and action codes (one action
code per template). User dialled digits are compared with the templates
in the Search Tables. If a match is found, the action corresponding to the
matching action code is executed. An action code may choose a route,
deny a call, assert the end of expected digits, etc.
sec second.
Select Route The route cannot be re-routed by any means, like the forced route. The
digits dialled that are matched (dialled by the subscriber) are stored in
the Select Digits Buffer, and all following digits are moved to the
Destination Number Buffer.
