Abstract:
   This document describes the RTP payload format for the Tactical
   Secure Voice Cryptographic Interoperability Specification (TSVCIS)
   speech coder.  TSVCIS is a scalable narrowband voice coder supporting
   varying encoder data rates and fallbacks.  It is implemented as an
   augmentation to the Mixed Excitation Linear Prediction Enhanced
   (MELPe) speech coder by conveying additional speech coder parameters
   for enhancing voice quality.  TSVCIS augmented speech data is
   processed in conjunction with its temporal matched MELP 2400 speech
   data.  The RTP packetization of TSVCIS and MELPe speech coder data is
   described in detail.
