These values provide information that may be useful for debugging an EGD network. The EGD signature and packet size
for the slow EGD exchanges are displayed.

 TELEPROT CH TESTS

The status information for two channels is shown here.
• CHANNEL 1 STATUS: This represents the receiver status of each channel. If the value is "OK", teleprotection is

enabled and data is being received from the remote terminal; If the value is "FAIL", teleprotection enabled and data is
not being received from the remote terminal. If "n/a", teleprotection is disabled.
• CHANNEL 1 LOST PACKETS: Data is transmitted to the remote terminals in data packets at a rate of two packets per
cycle. The number of lost packets represents data packets lost in transmission; this count can be reset to 0 through the

COMMANDS CLEAR RECORDS
• VALIDITY OF CHANNEL CONFIGURATION: This value displays the current state of the communications channel
identification check, and hence validity. If a remote relay ID does not match the programmed ID at the local relay, the
"FAIL" message will be displayed. The "N/A" value appears if the local relay ID is set to a default value of "0", the chan-
nel is failed, or if the teleprotection inputs/outputs are not enabled.
