SONET is fiber with telephony
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.
What is the PSTN?
PSTN stands for the Public Switched Telephone Network. Generally
this refers to the analog phone line standards that are almost
universally implemented, plus the T-Carrier trunks such as T1
lines and ISDN PRI trunks that support PBX systems. The PSTN is
constructed on a circuit switched model, as contrasted with enterprise
VoIP systems that are packet switched.
