Title:
CONTROLLING MULTI-PORT HUNT GROUPS IN A DISTRIBUTED CONTROL SWITCHING SYSTEM
Document Type and Number:
WIPO Patent Application WO1986004763
Kind Code:
A3
Abstract:
A distributed control switching system where the system control units cooperatively perform the terminating port determination function. Multi-port hunt groups having members that span a number of switching modules each having an associated control entity, are controlled in an efficient manner by assigning, for each multi-port hunt group, one of the switching modules as the group controller for that multi-port group. All calls to a given group necessarily require a control communication with the group controller which maintains the dynamic busy/idle data for the group and performs the hunting function to assign idle group members to calls.
