Claim:
1. A method of communicating between a management console and a remotely located remote digital terminal for terminating subscriber lines, via a class 5 telecommunications switch, comprising the steps of establishing an IP connection between the management console and the class 5 switch, establishing a synchronous telecommunications transport connection between the class 5 switch and the remote digital terminal, setting up a voice call between the management console and the remote digital terminal, passing the voice call over the IP connection as a VOIP call, passing the voice call over the synchronous telecommunications transport connection as a PCM encoded call, encapsulating an IP data stream as voice call data in the VOIP and PCM encoded voice call, recognizing, at the remote digital terminal, that the call relates to controlling the operation of the remote digital terminal, and extracting the IP data stream to establish an end-to-end IP connection between the management console and the remote digital terminal, for controlling the operation of the remote digital terminal.
