attached to the system side (MODE.HDLCI = ´1´), so called “inverse configuration”) only
BOM messages coming from the system side can be detected. BOM messages coming
from the system side are not included in (ANSI-)standards, but can be handled by the
OctalFALC
12.5
The kind of count up behaviour of the frame error counter FEC can be controlled by the
register bit DEC.FECC because there are differences in the ANSI standard T1-403
between 1995 and 1999:
-FEC count up will be done also if a severely error occurs as it is described in ANSI-T1-
403 1995: DEC.FECC = ´0´.
-FEC count up is not done if a simultaneous severely error occurs as described in ANSI-
T1-403 1999: DEC.FECC = ´1´.
Note that the FEC status is stored in the registers FECH and FECL.
12.6
An SEF interrupt statusbit ISR7.SEFEI and an appropriate mask register bit IMR7.SEFEI
is provided, which shows SEF errors according to ANSI-T1.231:
6.1.2.2.2: “An SEF defect is determined by examining contiguous time windows for
frame bit errors. For SF, the window size is 0.75 ms, and only the F
For ESF, the window size is 3 ms, and only the frame pattern sequence (FPS) bits are
examined.
An SEF defect occurs when two or more frame bit errors in a window are detected. An
SEF defect is terminated when the signal is in-frame and there are less than two frame
bit errors in a window.
Note that an AIS-CI and an AIS signal (alarm indication signal), or a signal that is OOF
(out of frame), will typically cause an SEF defect.
12.7
