Console Control Card (Basic)
2.12 The console control card provides the interface between the
system and two consoles. Console control card number
-1
(position 17) is allocated to the maintenance console connector and
the Supervisor console number 1 connector. Console control card
number 2 (position 16) is allocated to the Supervisor console number 2
connector. The card provides both voice and data signals to and from
each console (see Figure 2-2). To identify the console, the operator
may press the
IDENT
button. The last segment in the DESTINATION
Display identifies the console as 0 for maintenance, 1 for console 1, or
2 for console 2.
