NOTE:
Performing a receiver or transmitter PLL test during normal
link operation will take the link down for the duration of the
test and the re-synchronization interval.
The internal self tests are listed in

threshold
Threshold of Performance Degradation
Usage:
threshold [<level>]
This command sets or displays the performance degradation
threshold(s) of the LEDR radio, at which time events are logged and
SNMP traps are generated. Setting these thresholds to zero or a negative
number will disable event logging and trap generation for those param-
eters.
Example Response:
:
threshold {rssi}: 0
threshold {snr}: 0
threshold {coffset}: 0
threshold {temp}: 110
threshold {15mines}: 900
threshold {15minses}: 900
threshold {24hres}: 86400
threshold {24hrses}: 86400
rssi—
dBm level below which an RSSI alarm is generated.
snr—
Value below which a signal-to-noise level alarm is generated.
coffset
—Maximum tolerable RF carrier frequency difference between
the local LEDR unit’s transmit frequency and the incoming RF signal
from the other LEDR radio.
temp
—Power amplifier temperature above which an alarm condition is
generated.
15mines
—Number of errored seconds within the last 15 minutes.
