CAUTION:
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.
