6.3 LOOPS
To check the correct operation a set of local and remote loops are made available. The commands are for-
warded by the WebLCT program. The loop is a manual operation that can be activated for a timeout period
specified by operator (0-172800sec.). The available loop facilities are:
• loopback on Ethernet LAN PORT (1)
• loopback on TRx port (2)
• I/Q loop: activation command of I/Q loop operates on both branch; RF transmission is squelched
(3).
