Abstract

Abstract As a result of the greatly different bit rates per connection in broad band switching systems, the control capacity required per broad band connection can fluctuate by more than three orders of magnitude. In order to achieve a uniform load distribution between the group processors in view of this fluctuating need for control capacity, the allocation of the line or trunk modules to the group processors is made variable during the operation of the switching system.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 128 words
A switching system, comprising: a switching network; a plurality of line module means for connection of subscriber lines to the switching network; a plurality of trunk module means for connection of trunk lines to the switching network; a plurality of group processor means for controlling the line module means and the trunk module means, said group processor means being connected to the switching network structurally independently of the line module means and trunk module means; and coordination processor means for allocating at least one line module means or trunk module means to one group processor means and for changing the allocation of at least one of said line module means or trunk module means to another one of the group processor means during operation of the switching system.
Claim 2
Dependent Claim 128 words
A switching system, comprising: a switching network; a plurality of line module means for connection of subscriber lines to the switching network; a plurality of trunk module means for connection of trunk lines to the switching network; a plurality of group processor means for controlling the line module means and the trunk module means, said group processor means being connected to the switching network structurally independently of the line module means and trunk module means; and coordination processor means for allocating at least one line module means or trunk module means to one group processor means and for changing the allocation of at least one of said line module means or trunk module means to another one of the group processor means during operation of the switching system.
Claim 3
Dependent Claim 40 words
A switching system according to claim 1 wherein said coordination processor means has an operator input means for permitting an operator to initiate said changing of the allocation of said at least one line module means or trunk module means.
Claim 4
Dependent Claim 38 words
A switching system according to claim 1 wherein said coordination processor means for making the allocation changeable includes means for making the allocation automatically changeable depending on traffic characteristics of the line module means or trunk module means.
Claim 5
Dependent Claim 128 words
A switching system, comprising: a switching network; a plurality of line module means for connection of subscriber lines to the switching network; a plurality of trunk module means for connection of trunk lines to the switching network; at least first and second group processor means for control of the line module means and the trunk module means, said first and second group processor means being connected to the switching network; and coordination processor means for allocating at least one line module means or trunk module means to the first group processor means and for changing the allocation during operation of the switching system so that a second group processor means assumes control of specific line or trunk modules that were previously controlled by the first group processor means.
Claim 6
Dependent Claim 128 words
A switching system, comprising: a switching network; a plurality of line module means for connection of subscriber lines to the switching network; a plurality of trunk module means for connection of trunk lines to the switching network; at least first and second group processor means for control of the line module means and the trunk module means, said first and second group processor means being connected to the switching network; and coordination processor means for allocating at least one line module means or trunk module means to the first group processor means and for changing the allocation during operation of the switching system so that a second group processor means assumes control of specific line or trunk modules that were previously controlled by the first group processor means.
Claim 7
Dependent Claim 181 words
A switching system, comprising: a switching network; a plurality of line module means for connection of subscriber lines to the switching network; a plurality of trunk module means for connection of trunk lines to the switching network; a plurality of group processor means for controlling the line module means and the trunk module means, said plurality of group processor means being connected to the switching network and not being directly connected to the line module means and the trunk module means so that each of the plurality of group processor means controls the line module means and the trunk module means through the switching network; and coordination processor means for allocating at least one of the plurality of line module means or at least one of the plurality of trunk module means to one of the plurality of group processor means and for varying the allocation during operation of the switching system so that the allocation of the at least one line module means or the at least one trunk module means to the one group processor means can be changed.
Claim 8
Dependent Claim 181 words
A switching system, comprising: a switching network; a plurality of line module means for connection of subscriber lines to the switching network; a plurality of trunk module means for connection of trunk lines to the switching network; a plurality of group processor means for controlling the line module means and the trunk module means, said plurality of group processor means being connected to the switching network and not being directly connected to the line module means and the trunk module means so that each of the plurality of group processor means controls the line module means and the trunk module means through the switching network; and coordination processor means for allocating at least one of the plurality of line module means or at least one of the plurality of trunk module means to one of the plurality of group processor means and for varying the allocation during operation of the switching system so that the allocation of the at least one line module means or the at least one trunk module means to the one group processor means can be changed.
