BLOCK CONTROL
You can use Block Control to restrict access to certain system resources for the purposes of trouble-shooting, e.g.
you might block a CO line from use in order to test the circuit while avoiding user access to the CO line circuit. To
use Block Control, you must know the cabinet number, board/module number and port number.
From the main PC-DBA Screen (during connection between the system and the switch - see page 84):
1) Go to MaintenanceXRemote ControlXBlock Control to display the Block Control screen.
2) Select the number of the board you want to block (or unblock).
IMPORTANT
When a board or port is blocked, it must be unblocked to regain access to the
resource.
