the transmitting direction is more than the delay in the receiving direction. A displayed value of "0.0" indicates that
either asymmetry is not present or can not be estimated due to failure with local/remote GPS clock source.
• VALIDITY OF CHANNEL CONFIGURATION: The current state of the communications channel identification check,
and hence validity, is displayed here. If a remote relay ID number does not match the programmed number at the local
relay, the "FAIL" value is displayed. The "n/a" value appears if the Local relay ID is set to a default value of "0" or if the
87L element is disabled. Refer to
• PFLL STATUS: This value represents the status of the Phase & Frequency Locked Loop Filter which uses timing infor-
mation from local & remote terminals to synchronize the clocks of all terminals. If
terminals are synchronized and 87L protection is enabled. If it is "FAIL", the clocks of all terminals are not synchronized
and 87L protection is disabled. If "n/a", then PFLL is disabled.
At startup, the clocks of all terminals are not synchronized and the PFLL status displayed is FAIL. It takes
up to 8 seconds after startup for the value displayed to change from FAIL to OK.
