3 Audio Outputs:

ƒ1 output (line level) via RCA connector providing audio from far end, in addition to dial tones. This output also supports S/PDIF. S/PDIF (Sony/Philips Digital Interface) is used by the Digital Natural Audio module.

ƒ1 AUX output (line level) via RCA connector providing a mixed signal between audio from the local side (except from the AUX input) and audio from the far end. This output is intended for connection to a telephone add-on system. When system is configured as stereo, this output will provide the left stereo information.

ƒ1 VCR output (line level) via RCA connector providing a mixed signal between audio from the local side (except from the VCR input) and audio from the far end. This output is intended for connection to a VCR. When system is configured as stereo, this output will provide the right stereo information.
