Framer Initialization (T1/J1)

Function

FMR4.SSC1/0

Selection of framing sync conditions

FMR4.FM1/0

Select framing format

FMR2.AXRA = 1

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

FMR4.AUTO = 1

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.

RCO.SJR

1) =1

FMR0.SRAF = 0

XSW.XRA = 1

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

Remote alarm handling via DL-

channel according to ITU-T

JG.704 using pattern

"1111111111111111"

RCO.SJR = 0

CRC6 calculation without FS/

DL-bits

RCO.SJR = 1

CRC6 calculation including FS/

DL-bits

FMR4.AUTO = 1

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.

FMR4.SSC1 = 1

FMR4.SSC0 = 1

FMR2.MCSP = 0

FMR2.SSP = 1

Synchronization and

resynchronization conditions,
