Exchange access categories in the internal numbering plan
A call can be transmitted to the public network by selecting a prefix from one of
the exchange access categories.
The cost type (Business, Private), cost centre (cost centre selection) or route (route
selection) is determined according to the prefix selected.
Route selection prefixes are the internal call numbers of the routes.
Route selection can also be used for routing in the private leased-line network.
