Alarms/Errors Overview
DS3
Alarms
AIS
(Alarm Indication Signal)
RX
: The M-frame contains zeros (0) for C-bits, ones (1) for X-bits,
1010... repeating sequence with a one (1) immediately following any of
the control bit positions for the information bits.
Idle
(DS3 Idle)
RX
: Subframe 3 of the M-frame contains zeros (0) for the three C-bits,
ones (1) for X-bits, 1100... repeating sequence with the first two bits
following each control bit set to 11 for the information bits.
OOF
(Out-OF-Frame)
RX
: Four consecutive frame bit errors are detected.
RDI
(Remote Defect Indicator)
RX
: Both X-bits of the M-Frame are set to “0”.
Errors
CP-Bit
(Control-Bit)
RX
: The three C-bits reserved to control bit stuffing are different of
“111” and “000”.
F-Bit
(Framing-Bit)
RX
: The frame alignment pattern received is different of “1001”.
P-Bit
(Parity-Bit)
RX
: The P-Bits does not match the parity of all the information bits
following the first X-Bit of the previous DS3 frame.
FEBE
(Far-End Block Error)
RX
: The three FEBE bits reserved for framing or parity error detection
contain the “000” pattern.
