Example:
*DM34 ABC (AS) (eq. name and alarm states)Main system: (state and fault messages)-frame alignment lostTributary 1:-no incoming 8M sig.Tributary 3:-loop to equipment
Possible fault or state messages:
*DM34 ABC (OK) or*DM34 ABC (A) or*DM34 ABC (AS) etc.
Main system:
The incoming main system signal is missing.
-no incoming 34M sig.
The frame alignment of the main system signal is lost.
-frame alignment lost
The incoming main system signal is the AIS
-AIS 34M
The error rate of the incoming main system signal is worse than the setthreshold value 1E-3 or 1E-4.
-BER > 1E-3 (or 1E-4)
The far-end alarm is received (Bit B11 of the frame structure).

The equipment has detected a fault in the memory test.
-memory fault
The equipment processor (CPU) has been reset or some other similarmalfunction. This fault message is obtained via the TMS only.
-eq. reset
The equipment has detected a fault in itself.
-fault in eq.
Tributary 1 (2, 3 or 4):
The incoming tributary signal is missing.
-no incoming 8M sig.
In addition, the tributaries provide some fault and state messages thatcorrespond to those of the main system.

9,7 EEPROM-test
The data on settings and identifications are stored in three copies in theEEPROM. Theprogram continuouslycompares these copiesof data andif one deviates from the others, it is automatically corrected to be thesameasthe others. The corrections are counted bya special counter and ifthe number exceeds 10000, the answer of the test will be:
Too many correctionsin EEPROM
If the correction does not succeed, i.e. the data will not remain in storage,the answer of the test will be:
EEPROM failed
If the correction succeeds, the answer will be:
OK
