Hardware Description
Remote alarm handling and CRC6 calculation are commonly selected by RC0.SJR

Framer Initialization (T1/J1)
Function
T1
Selection of framing sync conditions
Select framing format
The transmission of RAI via the line interface is done
automatically by the FALC
Alignment (FRS0.LFA = 1). If framing has been reinstalled RAI
is automatically reset
Automatic synchronization in case of definite framing candidate
(FRS0.FSRF).
In case of multiple framing candidates and CRC6 errors different
resynchronization conditions can be programmed via
FMR2.MCSP/SSP.
CRC6 calculation without FS/
DL-bits
Automatic synchronization in case of definite framing candidate
(FRS0.FSRF). In case of multiple framing candidates and CRC6
errors different resynchronization conditions can be
programmed via FMR2.MCSP/SSP.
