The CURRENT STATE line shows the current status of the available local loops:
ON or OFF.
Procedure:
To change the condition of any test loop, type the appropriate code number to go
to the loop-control screen (a typical screen is explained in subsection 18).
After completing the required actions, type
Q
to return to the DIAGNOSTICS
screen.
16. REMOTE LOOPS Screen
Purpose:
View the current status of the remote sub-channel and composite
channel loops and go, if desired, to the control screen for any of these loops
(see subsection 18). Its functions are similar to those of the LOCAL LOOPS
screen, described in subsection 15.
NOTE
Remote digital loopback is performed by toggling pin 21 to the modem
connected to the local MiniStat-Four. This forces the modem to transmit
a command to the remote modem.
Before attempting to perform loopback, make sure that:
1. The local and remote modems do have V.54 remote loopback capability.
2. Pin 21 of the local modem is configured to accept loop command.
3. Jumper Pin 21 of the MiniStat-Four is set to ON.
17. MODEM LOOPS Screen
Purpose:
View the current status of the modem loops and go, if desired, to the
control screen for any of these loops (see subsection 18). Its functions are similar
to those of the LOCAL LOOPS screen, described in subsection 15.
18. Loop Control Screens
Purpose:
Change the current status of the test loop selected on one of the loop-
selection screens (see subsections 15, 16, or 17).
Description:
Code numbers 1 and 2 list the two possible conditions of the selected loop: ON or
OFF.
