1. In a switched communications network comprising:
- a first central office switching system connected to subscriber lines connected to subscriber premises terminals including at least one signal switching point for selectively providing switched communications between subscriber lines;
a second central office switching system connected to subscriber lines connected to subscriber premises terminals including at least one signal switching point for selectively providing switched communications between subscriber lines;
a controller arranged separately from the central office switching systems and being connected to at least the signal switching points connected to said central office switching systems through at least one signal transfer point arranged to convey control data to effect communications, said controller storing processing and routing data;
each said central office switching system providing selective communications between subscriber lines and a centralized message processing and storage system for handling multiple different types of message information, a method comprising;
forwarding from said first central office switching system to a first of said centralized message processing and storage systems message information of a first type directed to a second of said centralized message processing and storage systems and storing said message information of said first type in said first of said centralized message processing and storage systems;
sending an inquiry to said controller;
sending a responsive message from said controller and in response to the message forwarding to said second of said centralized message processing and storage systems via signal switching points and at least one signal transfer point said message information of a first type.

Abstract
A system and method of effecting transfer of message information of varied types from one centralized messaging system to another messaging device in a switched communications network having a plurality of central offices connected to subscriber terminals and connected together by trunks wherein the transfer of the message is effected through a common channel signaling network without using the trunks.

7. In a switched communications network comprising a plurality of signal switching points associated with subscriber lines connected to subscriber premises terminals, said signal switching points being connected by trunks for selectively providing switched communications between subscriber lines, a controller arranged separately from the trunks and being connected to at least some of the signal switching points through at least one signal transfer point arranged to convey control data to effect communications, said controller storing processing and routing data, at least one of said signal switching points being connected to a centralized message processing and storage system for storing message information of different types directed to subscribers, a method comprising:
-
forwarding to said centralized message processing and storage system a message of a first type directed to another message processing and storage system and storing said message information of said first type in storage in said centralized message information processing and storage system for storing message information of different types; sending an inquiry to said controller; sending a responsive message from said controller and in response to the message forwarding to said other message information processing and storage system via signal switching points and at least one signal transfer point the message information of a first type stored in the first-mentioned centralized message information processing and storage system. - View Dependent Claims (8, 9, 10, 11)

12. A switched communications network comprising:
-
a first central office switching system connected to subscriber lines connected to subscriber premises terminals including at least one signal switching point for selectively providing switched communications between subscriber lines; a second central office switching system connected to subscriber lines connected to subscriber premises terminals including at least one signal switching point for selectively providing switched communications between subscriber lines; a controller arranged separately from the central office switching systems and being connected to at least the signal switching points connected to said central office switching systems through at least one signal transfer point arranged to convey control data to effect communications, said controller storing processing and routing data; at least one of said switching systems providing selective communications between subscriber lines and a centralized message information processing and storage system capable of handling message information of different types; the other of said switching systems providing selective communication with information processing and storage devices connected to subscriber lines; said controller responding to signals from a signal transfer point to control the transfer of message information of a first type from said centralized message information processing and storage system to another processing and storage system for message information of said first type via at least one signal transfer point.

- 13. A switched communications network comprising a plurality of signal switching points associated with subscriber lines connected to subscriber premises terminals, said signal switching points being connected by trunks for selectively providing switched communications between subscriber lines, a network controller arranged separately from the trunks and being connected to at least some of the signal switching points through at least one signal transfer point arranged to convey control data to effect communications, said network controller storing call processing data associated with subscribers who are associated with the subscriber lines connected to consumer premises terminals, at least two of said signal switching points being connected to centralized message information processing and storage systems for storing messages directed to subscribers, said centralized message information processing and storage systems having the capability of handling message information of different types, said signal transfer point connected to said centralized switching systems responding to signals intended to transfer message information of a first type from one centralized message processing and storage system to another centralized message processing and storage system to send an inquiry to said network controller, said network controller sending a responsive message causing said signal transfer point to forward the message information from said one centralized message processing and storage system to the other centralized message processing and storage system via signal switching points and at least one signal transfer point.
- 17. A method of forwarding a first type of digitized message information stored in one centralized message system capable of storing digital message information of multiple types, said centralized message system being connected to a switched telecommunications network having switching systems connected together by trunks to another centralized message system, which switching systems are controlled by a network controller arranged separately from the trunks and constituting part of a common channel signaling system for said switched telecommunications network, comprising the steps of sending an inquiry to said controller and, reactive to a response from said controller, incorporating said message information of a first type into common channel signaling packets, transporting said packets via packet switching through said common channel signaling system, and storing said information in said other centralized message system.
