AMI Statistics Commands
The fields in this display have the following meanings:
ds3FramingLOSs
Specifies the number of seconds in which Loss Of
Signal (LOS) errors were detected by the DS3 Receive
Framer block.
ds3FramingLCVs
Indicates the number of Line Code Violations (LCV)
that were detected by the DS3 Receive Framer block.
ds3FramingSumLCVs
Shows the number of DS3 information blocks (85
bits) which contain one or more Line Code Violations
(LCV).
ds3FramingFERRs
Displays the number of DS3 framing error (FERR)
events.
ds3FramingOOFs
Specifies the number of DS3 Out Of Frame (OOF)
error events.
ds3FramingFERFs
Indicates the number of seconds in which a Far End
Receive Failure (FERF) state has been detected by the
DS3 Receive Framer block. The FERF signal alerts the
upstream terminal that a failure has been detected
along the downstream line.
ds3FramingAISs
Shows the number of seconds in which Alarm Indi-
cation Signals (AIS) were detected by the DS3
Receive Framer block. AIS means that an upstream
failure has been detected by the far end.
ds3FramingPbitPERRs
Lists the number of P-bit parity error (PERR) events.
ds3FramingCbitPERRs
Shows the number of C-bit parity error (PERR)
events.
ds3FramingFEBEs
Indicates the number of DS3 far end block error
(FEBE) events.
ds3PlcpFERRs
Lists the number of Physical Layer Convergence Pro-
tocol (PLCP) octet error events.
ds3PlcpLOFs
Shows the number of seconds in which Loss Of
Frame (LOF) errors were detected by the PLCP
(Physical Layer Convergence Protocol) receiver. LOF
is declared when an Out-Of-Frame state persists for
more than 1ms. LOF is removed when an in-frame
state persists for more than 12ms.
