TC12 SYSTEM OVERVIEW
TC12 is a telecommunications system designed for Urban Traffic Control (UTC). It
consists of a number of Outstation Transmission Units (OTUs) positioned in the
traffic controllers or detector cabinets. These communicate with a central office
containing a number of Instation Transmission Units (ITUs). Communication
between the two is by means of private wire telephone lines, which can be
operated at different baud rates and signal levels.
The ITU sends a Control message to the OTU that will cause the OTU to form the
appropriate Reply message, which it will send back. These messages are of
configurable size depending on the amount of data transfer needed.
The ITU connects to a Traffic Control Computer (TCC) system consisting of one or
more UTC TCC computers and one or more PCs communicating with each other
via an Ethernet link. This system drives the ITU modems, which communicate with
the OTU via the telephone lines.
The ITU also drives the System Fault Indication Panel (SIP) which indicates, by
means of LEDs and an audible alarm, failures in the TCC. The SIP is housed in
the ITU cabinet but there is also the option of driving a remote SIP. The ITU can
also be used to drive a TC8 Instation.
There is also facility for an Instation Test Set which can be used to measure signal
levels and monitor communications (both data and errors) on the telephone lines.
It can also be used to take the place of either Instation or Outstation for testing.
