Designates a bi-directional transfer of data for a single call between a voice device processing that call and the SCbus. Digitized voice from the analog or T-1/E-1 interface device is transmitted over the SCbus to the voice receive (listen) channel for processing by the voice device. The voice device sends the response to the call over the voice transmit channel to an SCbus time slot that transmits this response to the analog or T-1/E-1 interface device.

Communication channel implemented by a base station or repeater used to transmit and receive voice information. Contrast with a base station or repeater functioning as a control channel used to transmit and receive channel assignment data or process other control commands from the system.

A channel used for transmission of voice data from a base station to a cellular phone (forward voice channel) or from a cellular phone to a base station (reverse voice channel)

A channel that is associated with an interface to the telephone network (T1, E1, LSE1/ LST1, or PRI). Any system application can run on a voice channel. Voice channel applications can be initiated by being assigned to particular voice channels or dialed numbers to handle incoming calls or by a soft seizure request to TSM from a DIP or the soft_szr command.

A signal path containing (at a minimum) an oscillator and VCA or their digital equivalent, and capable of producing a note. On a typical synthesizer, two or more voice channels, each with its own waveform and parameter settings, can be combined to form a single note.
