Background information on bert command:
The bit error-rate test command, bert, is used to evaluate the link
between the LEDR data interface and the customer premises equipment
(CPE). When used, the LEDR radio will send a test pattern out of the
LEDR FT1/E1 Data Interface lines towards the CPE while simulta-
neously attempting to receive the same pattern back from the CPE. For
example, you can loopback the CPE’s external data device’s I/O, then
issue a
bert command to the LEDR radio to check the integrity of the
wire connection. The test pattern can be user-selectable. (See bert com-
mand Options above for further information.)
NOTE: The bert command will not test or evaluate the integrity of the
LEDR radio link. (See “BENCH TESTING OF RADIOS” on
Page 122 for further information.)
NOTE: When operating FT1 or FE1 interfaces, this command tests all
T1/E1 timeslots without regard to the timeslot command’s
configuration.
boot Boot from Active/Archive Software
Usage:
boot [<1|2|-s|-o>]
This command is used to view or change the radio’s active software
image. If
boot is entered alone, the currently active firmware image (1 or
2) is displayed. A selection of 1 or 2 after the command (e.g.,
boot 2) ini-
tiates a reboot from that image. (A message appears to confirm that you
wish to reboot the radio firmware.) Upon reboot, the radio and all radio
functions are restarted in a manner similar to turning the radio power off
and then on again. The radio is taken out of service until it re-initializes,
and the link loses synchronization until the reboot process completes
and the demodulators at both ends reacquire the radio signals.
A choice of software images allows booting an alternate version of radio
software. The ability to have two radio-resident software images allows
radio software reprogramming over-the-air and the ability to restore
operation to the original software if required.
Subcommands:
1 Boot from Image 1
2 Boot from Image 2
-s Boot from the active (same) image
-o Boot from the inactive (other) image
