The systems co-operate to provide users (human or automated) with a data communication service. The AMHS network is composed of interconnected ATS Message Servers that perform message switching at the application layer (Layer 7 in the OSI model). Direct users connect to ATS Message Servers by means of ATS Message User Agents.
One example is an open transition automatic transfer switch (ATS). During the split second of the power transfer the flow of electricity is interrupted. Another example is a manual three position switch or circuit breaker, with utility power on one side, the generator on the other, and "off" in the middle, which requires the user to switch ...

The modems connect, and both modems report "connect". (In practice, most modems report more information after the word CONNECT — specifying the speed of the connection.) Also, at this time, both modems will raise the DCD, or Data Carrier Detect signal, on the serial port. abcdef: abcdef
Automatic train stop or ATS is a system on a train that automatically stops a train if certain situations occur (unresponsive train operator, earthquake, disconnected rail, train running over a stop signal, etc.) to prevent accidents.
The Bell System issued specifications for the modular connectors and their wiring as Universal Service Order Codes (USOC), which were the only standards at the time. Large customers of telephone services commonly use the USOC to specify the interconnection type and, when necessary, pin assignments, when placing service orders with a network ...
