Notes
(1)
An abnormal operating condition has occurred which may or may not affect system operation. To verify that system
operation is not negatively affected, advise the nearest field support office of the circumstances leading to this alarm and
the details displayed with it.
(2)
This alarm is not generated for module position 9 when position 9 is reserved for a super-rate connection by position 1.

Viewing alarm queues
Alarm queues are displayed with the most recent alarm at the top of the list. If there
are too many alarms in the list for the data area to show them all, you can scroll
through the list to view earlier or later alarms.

Description of alarm
The Control card and software versions are mismatched, or a necessary Control card
module is missing. Check the second parameter in the subcode to identify the details of
the mismatch as follows:
0 - unknown reason
1 - the card and software are incompatible
The EPROM checksum self-test described in Table 4-3 has failed.
The SEEP self-test described in Table 4-3 has failed.
An over-active device has caused a signaling fault.
The timing source has changed.
The timing source has been lost.
The system attempted to recover a lost timing source but did not succeed.
This is a diagnostic software alarm related to Device Administration. If you are reporting
any problems to your representative, make sure you include this alarm as it can help to
identify a failure mechanism.

The connection between a DNIC or 2B1Q module and a DTU or DSU has been lost. The
first parameter identifies the module. This alarm is not raised if the module is removed from
its position. Locate the trouble and reconnect or replace the equipment as necessary.
The Thermometer self-test described in Table 4-3 has failed.
The 4 ms timer or 125 µ s timer self-test described in Table 4-3 has failed.
An alarm queue has overflowed. Delete some or all alarms.
This is an E1 alarm that indicates that there has been a timeslot 16 multiframe alarm at the
far end.
One of the UART presence or UART send/receive self-tests described in Table 4-3 has
failed.
The installed interface card and the configuration do not correspond.
A module position is configured for a module type other than the type installed. Check the
first parameter to determine the position number. Either reconfigure the position to match
the module type installed or install the type of module for which the position is configured.
(2)
The installed module and the configuration do not correspond or no module has been
installed.
