Abstract
A method and apparatus for utilizing a multi-channel digital communications line provides dynamic bandwidth allocation of user data channels for supporting a data device and an audio device, such as a digital telephone. In the preferred embodiment, the communications line is an ISDN line in which both B-channels are dedicated to data transfers for the data device when the audio device is idle. However, the signaling channel is continuously monitored to detect events in which incoming and outgoing voice calls are indicated. One of the B-channels is surrendered in order to allow connectivity of the voice call. Reallocation of the surrendered B-channel to the support of a data transfer occurs upon detection of a D-channel signal that indicates that the audio device has released the channel.
