get performance log This command lists all performance entries in the log since the log was
enabled, or after it was last cleared. Ctrl-c aborts the listing.

Table 4-2 Performance Log Durations
Between 6000 and 8000 entries can be logged before the Performance Log memory is full. Once the
memory is full, new entries will overwrite the oldest entries. The following table assumes that an average
of 7000 entries will occur before memory overflow. If the memory accepts more entries, then the log
duration before overflow will be extended.
Logging Interval Log Duration
15 secs (minimum) ~ 29 hours
1 minute ~ 116 hours (~ 4.8 days)
15 minutes (default) ~ 73 days (~ 2.4 months)
1 hour ~ 292 days (~ 9.7 months)
24 hours (maximum) 7000 days (~ 19.2 years)
4.8 Radio Loopback
Horizon provides a radio loopback facility for analysis of transmit or receive path issues. Invoking a radio
loopback is service affecting and will stop all data transfer. There are two options:
• Straight radio loopback - Ethernet traffic is not looped back to the network, Ethernet traffic is
discarded and the RF portion of the Horizon unit is placed in loopback (see Error! Reference
source not found.).
• Radio loopback plus network loopback – Ethernet traffic and the radio are placed in loopback
During the loopback, if the modem transmitter loss of sync alarm is not active, then both the transmitter
and receiver of the Horizon unit under test are functioning correctly. A user configurable time limit can be
applied to the loopback feature (default is 30 seconds). Once the time limit has expired the loopback will
be automatically removed. Note that the far end transmitter should be muted when analysing the near
end system using the radio loopback feature.
