Framer Initialization (T1/J1)
Selection of framing sync conditions
Select framing format
The transmission of RAI via the line interface is done automatically
by the FALC56 in case of Loss of Frame 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.
