| Summary: | This paper discusses Digital Speech Interpolation (DSI) advantage of Statistical Time Division Multiplexer (STDM)
for Random Packet Loss scenarios. In order to harness this advantage each source speech is compressed at 6.4 kbps,
Voice Activity Detector (VAD) is used for each source, and packet loss mechanism is introduced to achieve
maximum DSI advantage. It is observed that for maximum of 9 users channel capacity, extra 3 users, i.e. total 12
users can be accommodated with 3% speech frame losses, which results in an advantage of 12/9 = 1.33.
