Abstract:
A method, carried out an arrangement that includes a switch, and terminals that are coupled to the switch through a serially connected arrangement of one or more shared overloadable resources, where each call established by said switch for a terminal belonging to said terminals occupies a portion of each of said one or more shared overloadable resources, and where each of said overloadable resources has an associated preselected number of channels that are reserved for communications of a first type, for establishing a telecommunications connection for a terminal of said terminals through said switch, comprising the steps of:when unoccupied capacity exists in that an unoccupied channel exists in each of said one or more shared overloadable resources, establishing said telecommunications connection for said terminal, when said terminal seeks to establish a connection belonging to a first class of connections, when unoccupied capacity exists, establishing said telecommunications connection for said terminal, when said terminal seeks to establish a connection belonging to other than said first class of connections, if each of said overloadable resources has a capacity of Ci channel, has a capacity of Ri reserved for calls belonging to said first class of connections, and has a number of unoccupied channels that is greater than Ci minus Ri, where i is an index designating one of said overloadable resources.
