ETS 300 347-1 Clause 16.1.1
Events
Functional Support Built-In MT9075
Operational Signal (normal frames, no RAI)
Interrupt T2I and status bit T2
Non-operational condition
Interrupt T1I and status bit T1
Loss of signal
Pin LOS and alarm bit LLOS
Loss of frame alignment
interrupt SYNI, alarm bit/SYNC and LBF counter
Reception of RAI
Interrupt RAII and alarm bit RAIS
Reception of AIS
Interrupt AISI and alarm bit AISS
CRC block received in error
Interrupt CRCI and alarm bits CRCS1/2
CRC error information (E-bit "0")
Interrupt EBI and status bit REB1/2
Detection Algorithms for Events & Signals (ETS 300 347-1 clause 16.1.2)
Normal frames: as per G.706
MT9075 supports G.706
Loss of frame alignment: as per G.706
RAI: (1) frame alignment condition; and (2) reception
of one bit A set to ONE
Supported by MT9075
Loss of Signal: (1) the signal amplitude is, for a time
duration of at least 1ms, more than 20dB below the
nominal output amplitude; OR (2) the input detects
more than 10 consecutive HDB3 ZEROS.
Same as (1) for pin LOS and alarm bit LLOS
AIS: (1) loss of frame alignment; AND (2) reception of
512 bit periods containing less than 3 binary ZEROS.
Interrupt AISI and alarm bit AISS of MT9075
CRC Error information: reception of one E-bit set to
ZERO.
Interrupt EBI and status bit REB1/2 of MT9075
Others
Link Identification Signal: normal frames received with
2 out of 3 Sa7 bits received set to ZERO.
Diverse accesses to all the Sa bits, interrupt on the Sa
bits status change.
Jitter and Wander: as per G.823
Internal jitter attenuator better than G.823
Loopbacks: remote loopback initiated by LE
six loopback functions
