Message
Figure
14. Format of Printer Message
including scp Code for
Terminal-Interchange
and Terminal-Control
Addresses
100 characters.
The format
is shown in Figure
14. On
output messages,
the end-of-message
(kom)
character
is the same for
either a printer
or lights
message. The
differences in
end-of-message
characters
for output
messages are EOM
complete, EoOM incomplete
(which
never reaches the agent’s set),
and Eom unsolicited. All
input and output control
codes used
at the agent’s set
are shown in Figure 15.
Special Terminal Sets
Terminal sets with
the same appearance
and line con-
nections as the agents’ sets may
be used for many other
purposes such as supervisors’ sets, dispatchers’ sets,
operation sets for maintenance
scheduling, and other
purposes. The functions of each of these types of
terminals are determined by programming.
For every terminal interchange, one of its terminals
(either agent’s set or supervisor’s set) must be located
within viewing distance of the interchange customer-
engineering panel
as a reliability aid
for the system.
This terminal (with the permanent
address of 1) will
also be the test terminal. Terminal
2 is also used for
customer-engineer
testing and should
be convenient to
the terminal interchange
and terminal 1.
The operator who turns on
power for the terminal
interchange at the beginning of the work period can
check for correct operation of the interchange by turn-
ing the interchange test switch to TEsT and typing a
message at terminal 1. If the terminal interchange is
operating correctly, the message will be returned
immediately from the interchange and will be typed
automatically at terminal 1. (Because of the nearness
of
terminal 1 to the terminal interchange, terminal 1
will
normally be used. However, this test can be per-
formed
by any terminal.) For this and other testing
reasons,
terminal set 1 is a “physical testing” set and
must
be located next to the terminal interchange.
Other
variations in agents’
terminal sets will be the
result
of individual customer systems needs.
