T1/E1 Diagnostics
T1 Diagnostics is used for troubleshooting T1 or E1. It shows the status of various conditions for
the selected module.
• Hourly Display: Double-click Hourly to see the number of errors that have occurred in
each hour for the past 24 hours.
• Daily Display: Double-click Daily to see the number of errors that have occurred during
several 24-hour periods.
• Hourly Summary: The hourly summary shows the number of errors that have occurred in
the past hour.
• Daily Summary: The daily summary shows the number of errors that have occurred in the
past 24 hours.
• Last Error Update Hour and Day: These fields show the date and time that the
information was last updated. (Information is automatically updated whenever a new
module is selected.)
• T1/E1 Status: Double-click T1/E1 Status to see the following fields. They show the status
of the T1 or E1 module and allow you to perform diagnostics. To update the information,
right-click anywhere and select Update All Statuses.
o Make Busy: This option can be used to busy-out all of the circuits. When it is enabled,
the module is busied out, just as it would be if the busy-out switch on the module was
used. To change this option, right-click the current Value and then select Enable Make
Busy. To turn off the Make busy, right-click again and select Disable Make Busy.
If the Make Busy LED is flashing rapidly on the module, someone pressed the Make Busy
switch. If this occurs, you must disable this Make Busy field.
o Loopback Tests: These options can be used for enabling and disabling the following
T1 loopback diagnostics and alarm. During the tests, LED indications and error
messages can be used to provide troubleshooting information. (The testing options
cannot be used in stand-alone programming mode.) To enable or disable one of the
tests, right-click its current Value, then select Enable. To end the test, right-click again
and select Disable. If the T1 or E1 Loopback timeout timer expires during a loopback
test, the loopback will be terminated automatically. The loopback tests are as follows:
– Digital Local Loopback: Allows you to check the transmission and reception of
alarm conditions between systems in a private T1 or E1 network. This tests the
framing chip on the module.
– Digital Remote Loopback: Allows you to check the transmission and reception of
test patterns conditions generated by the T1/E1/PRI module. This tests the framing
chip on the module.
– Transceiver Local Loopback: Allows you to check the transmission and reception of
alarm conditions generated by the T1/E1/PRI module. This tests the transceiver
chip on the module.
– Transceiver Remote Loopback:
Allows you to check the transmission and reception
of test patterns between the T1/E1/PRI module and the public network. This tests
the transceiver chip on the module.
– Transmit Blue Alarm: This sends a Blue alarm over the public or private network
interface for testing purposes.
• Line Build-Out: This information is shown here for reference purposes only. To program
Line Build-out for the T1/E1/PRI module, see page 6-130.
NOTE
The T1 or E1 circuits should be busied out before any diagnostics
procedures are performed. If not, the module will go into Red Alarm and
drop all active calls.
