							GLOSSARY
Wide Area Telecommunications Service (WATS)
A service that allows calls to a certain area or areas for a flat-rate charge based on
usage.
Wink-Start Tie Trunk
After establishing a connection with a distant switching system for an outgoing call,
the system waits for a momentary signal (wink) before sending the digits of the called
number. Similarly, on an incoming call, the system sends the wink signal when ready
to receive digits.
Write Operation
The process of putting information onto a storage medium such as magnetic tape.
ZCS (Zero Code Suppression)
Zero Code Suppression (ZCS) line coding format monitors the transmit bit stream
and prevents a string of eight zeros from occurring. It forcibly changes one zero to a
one, to meet the ones-density requirement.
800 Service
A service that allows incoming calls from a certain area or areas to an assigned
number for a flat-rate charge based on usage.
