ABSTRACT:
This invention is a method of remotely accessing an Intelligent Network Channel Terminating Equipment device to expedite the testing and servicing of telecommunications circuits.
Intelligent Network Channel Terminating Equipment devices from different manufacturers have different operating characteristics. Therefore, prior to remotely accessing and operating an Intelligent Network Channel Terminating Equipment device in a telecommunication circuit from a remote location, the operating characteristics of the device must be determined. At the heart of the invention is our recognition that Intelligent Network Channel Terminating Equipment can be categorized according to their operational characteristics and that the type of Intelligent Network Channel Terminating equipment device present at a remote location can be identified from its response to signals which are sent to the Intelligent Network Channel Terminating Equipment device.
