Abstract
An interface for use in a telephone communication system provides for connection of a telephone switch to an IP network, allowing data signals between the telephone switch and a VMS to be transmitted by the IP network. In addition to transmission of the signals over an IP network, the interface can be configured to provide additional functionality including translation of the message protocol; connection of the interface to a network operations center; verification of message accuracy and completeness; acknowledgment of the receipt of a message; activation/deactivation of a message waiting indicator; connection to an SS7 network; back-up transmission between the IP network and the switch; and proxy/redirect of voice signals.
Claims17
An interface for transmitting data messages between a telephone switching system and an adjunct processor comprising:
- a first connector for connecting the interface to the telephone switching system;
- a second connector for connecting the interface to the telephone switching system;
- wherein said first and second connectors provide two simultaneously active links for carrying the data messages between the interface and the telephone switching system;
- wherein the data messages are received by said simultaneously active links, translated between data message protocols by said interface, and transmitted to said adjunct processor;
- and
- wherein when a first or second link fails, any remaining of the data messages are carried on a remaining active one of said links.
An interfacing method for processing data messages between a telephone switching system and an adjunct processor and for translating data messages between data message protocols comprising the steps of:
- providing an interface including first and second connectors for connecting the interface to the telephone switching system;
- connecting the telephone switching system to said interface utilizing said first and second connectors to provide two simultaneously active transmission links between said telephone switching system and said interface;
- transmitting the data messages between the telephone switching system and the adjunct processor utilizing said simultaneously active transmission links;
- and
- wherein when one of said active transmission links fails, any remaining of the data messages are transmitted on a remaining one of said active transmission links.
