ABSTRACT:

STATEMENT OF FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
Not Applicable
BACKGROUND OF THE INVENTION
1. Technical Field
This invention relates in general to telecommunications and, more particularly, to devices for providing enhanced services.
2. Description on the Related Art
The features provided by telecommunications over the last decade has been rapidly increasing. While in past years the telephone network was solely dedicated to providing connections between phones, today's telephone network provides many enhanced services to facilitate communications. Such features include voice mail, call forwarding, caller ID, fax on demand, voice response services and many others.
The ability to provide enhanced features has come largely from the emergence of AIN (Advanced Intelligent Network). In order to connect to the AIN, intelligent AIN-compatible switches are used.
While there is significant enthusiasm to provide the enhanced features supported by the AIN, the cost of providing these features can be prohibitive, since telephone service providers have a significant investment in older, non-AIN compatible switches. These switches mainly set up and tear down phone calls and do not support connection to the AIN.
Accordingly, the need has arisen for a technology to provide enhanced services in conjunction with existing non-AIN compatible switches.
BRIEF SUMMARY OF THE INVENTION
In the present invention, an electronic device for providing enhanced telecommunication functions, comprises circuitry for providing a switching service function communicating with external switches and translating externally received signals into an independent internal protocol and for providing specialized resource functions. An internal service control function may be provided by the circuitry or the circuitry may be configured to couple to an external service control peripheral.
The present invention provides significant advantages over the prior art. The device may be configured as an IP to operate in a number of different circumstances. Using an internal protocol independent of the external protocol(s) to communicate between subsystems of the IP allows the device to be easily modified and expanded as circumstances require. The IP can be configured with an SCF to provide a complete service node.
