System and method for message communications in a distributed telecommunications switch
First Claim
1. A communications system in a distributed telecommunications switch having a service unit and at least one delivery unit, comprising:
- a plurality of delivery unit network controllers residing in the at least one delivery unit;
at least two service unit network controllers residing in the service unit;
an administration network coupled to a first one of the plurality of delivery unit network controllers and to a first one of the two service unit network controllers, the administration network transporting messages having administration information between the service unit and the at least one delivery unit; and
a call processing network coupled to the remaining of the plurality of delivery unit network controllers and to the second one of the two service unit network controllers, the call processing network transporting messages having call processing information between the service unit and the at least one delivery unit, wherein the first one of the plurality of delivery unit network controllers and the first one of the two service unit network controllers are not coupled to the call processing network.
