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 is latency dealt with
in VoIP?
Latency means the time delay between transmission and reception
of a signal. Network traffic variations often result in latency
variations from packet to packet known as jitter. Jitter buffers
on the receiving end smooth out the variations to deliver a cleaner
voice signal.
