The General Information screen (Figure 25) shows the
Loop Deployment Guidelines for this type of circuit.
Should trouble occur on the circuit, many test details are
available here.
The Virtual Terminal Session Control screen (Figure 26)
allows the user to log into the H2TU-C from the H2TU-
R. Terminal control of the H2TU-C is retained until 5
minutes of idle time passes, or it may be released
immediately by pressing
CTRL+X.
