Abstract
A system and method enabling a remote customer station (server, CPE or end user) to control, or modify, selected functional capabilities of a telephone switch via control messages sent after cell setup and during the course of a data stream. The customer station receives back from the telephone switch indications of modifications in status of the switch occurring in response to the control messages. The functional capabilities which may be modified include both software and hardware configurations of the telephone switch.
Claims51
A method for establishing a call between a customer station and a telephone switch in a suppressed ringing protocol environment comprising the step of:
- transmitting control messages from the customer station to the telephone switch during data communications of the call to control a modification of one or more functional capabilities of the telephone switch;
- wherein the modification of the one or more functional capabilities of the telephone switch occurs in the telephone switch;
- wherein the telephone switch comprises one or more variables that control treatment of the call, wherein the modification of the one or more functional capabilities comprises a modification of the one or more variables of the telephone switch;
- wherein the modification of the one or more variables of the telephone switch modifies a duration of the call.
A method for establishing communications between customer premises equipment and a server through a switch unit having a protocol interface comprising the steps of:
- establishing a communication link between the server and the protocol interface;
- passing control messages from the server to the protocol interface to selectively modify functional capabilities of the switch unit associated with communications between the server and the customer premises equipment;
- and
- passing status messages representative of modifications in status of the switch unit resulting from the control messages from the switch unit and through the protocol interface to the server;
- wherein the modifications in status of the switch unit comprises a modification to one or more functional capabilities in the switch unit;
- wherein the switch unit comprises one or more variables that control treatment of the communications between the customer premises equipment and the server, wherein the modification of the one or more functional capabilities comprises a modification of the one or more variables of the switch unit;
- wherein the modification of the one or more variables of the switch unit modifies a duration of the communications between the customer premises equipment and the server.
A system for establishing communications comprising:
- a telephone switch having functional capabilities for establishing suppressed ringing communications and for generating status messages representative of status of the functional capabilities;
- and
- a customer station for requesting that the telephone switch establish suppressed ringing communications and for generating control messages to control a modification of the functional capabilities of the telephone switch;
- wherein the modification of the one or more functional capabilities of the telephone switch occurs in the telephone switch;
- wherein the telephone switch transmits the status messages to the customer station in response to the control messages to indicate the modification of the functional capabilities;
- wherein the telephone switch comprises one or more variables that control treatment of the suppressed ringing communications, wherein the modification of the functional capabilities comprises a modification of the one or more variables of the telephone switch;
- wherein the modification of the one or more variables of the telephone switch modifies a duration of the suppressed ringing communications.
