Clock
This shows the module's time and date. Use the set
clock command to set the time, using the 24-hour
format. Use the set date command to set the date,
specifying all four digits for the year.
Examples:
set clock 0:02:45–Sets the time to 12:02:45
a.m.
set date 12/29/2003–Sets the date to
December 29, 2003.
16.5.3 Performing Checkback Tests
The Universal Checkback Module's primary
function is to perform checkback tests, verifying
that your carrier communication path is operating.
You can perform checkback tests in several ways:
• Physical switch request
• Manual request from your PC
• Automatic timed test
• Automatic periodic test
• Automatic carrier recovery
• Remote-initiated periodic tests
• Remote-initiated timed tests
16.5.3.1 Physical Switch Request
As noted earlier, you can physically initiate a
checkback test from the module's front or rear
panel. At the front panel, push and release the
"TST" switch. At the rear panel, momentarily
close the external switch connected to TB6-
2/TB6-2. This works with both a remote or master
module.
16.5.3.2 Manual Request from Your PC
Using your computer, you can manually request a
test using the do checkback command. See
"Issuing Checkback Commands" later in this
chapter for details on using your PC to issue
commands.
16.5.3.3 Automatic Timed Test
When this option is enabled, the master checkback
module initiates checkback tests at four user-
specified times. For example, you might set these
times to be 4:00, 13:00, 14:00, and 23:00. You can
only set times to the nearest hour. The test then
occurs at the start of the hour plus five minutes,
unless the module is busy with another message.
To enable this option, you must do the following:
1. Turn on the automatic test feature:
set auto on
This changes the "Auto Tests" setting to "On".
2. Set the interval type to "timed":
set int time
This changes the "Interval Type" setting to
"Timed".
3. Set the four checkback test times:
set time[#] [hh]
Where "#" is the time's place in the daily sequence
(i.e., 1, 2, 3, or 4), and "hh" is the desired hour in
24-hour format (e.g., 8, 12, 16, 20). This changes
the "Checkback Time 1-4" setting to reflect the
four times you specified.
You can only make these settings changes if the
module's DIP switch is set to "CUSTOM".
16.5.3.4 Automatic Periodic Test
Instead of a timed test, you can set the master
checkback module to initiate tests periodically,
say, every four hours. The shortest interval you
can set is one hour, and the longest is 120 hours.
The periodic interval is reset after one of the
following:
• Sending or receiving a good checkback
test, including manual tests
• Attempting to execute a checkback test at
the Periodic Interval.
