IP Telephony FAQ's:
SONET is fiber with telephony
heritage
SONET was designed to carry telephone conversations, so it handles
the TDM (time division multiplexing ) digital voice channels from
PBX and telephone carrier switches easily. Because it is synchronized
like the T-carriers, you can add or remove channels at will with
an add-drop multiplexer. This makes it easy to interconnect a
group of locations in a regional or even nationwide network.
How Does VAD Work?
VAD, or Voice Activity Detection, is a technique that reduces
bandwidth in VoIP telephone systems by listening for the silence
in normal conversations and not transmitting any packets during
these periods.
