CAUTION:
If the TN788 Voice Conditioner circuit pack (VC-BD) is not Vintage 2 or later,
it must be replaced.
The TN788 Voice Conditioner circuit pack (VC-BD) is a service circuit pack that
provides conditioning for the audio signals from multimedia equipment based on
the CCITT H.221 standard. The TN788 transcodes, gain adjusts, and bridges the
audio bit streams demultiplexed by the TN787 (MMI) circuit pack and transmits
encoded, exclusive audio conference sums onto the TDM bus so that the MMI
can multiplex the audio, video, and data streams for the H.221 endpoints.
