SFRME

When the Single Framing Bit Error (SFRME) bit is set to logic one, then the J2-FRMR will

indicate (to the PMON) a single framing error for every J2 multi-frame which contains one or

more framing errors. When the SFRME bit is set to logic zero, the J2-FRMR will identify

every framing error to the PMON.

LOSTHR[1:0]

The LOS Threshold bits select the number of consecutive zeroes required before the J2-

FRMR will declare LOS, and the number of bit periods without an occurrence of excess

zeroes that must pass before the J2-FRMR will de-assert LOS. The thresholds are described

in Table 18:

Table 18 J2 FRMR LOS Threshold Configurations

LOSTHR[1]

LOSTHR[0]

Threshold

255

Thus, if LOSTHR[1:0] = 11 binary, LOS will be declared after the 255th consecutive binary

zero, and de-asserted when 255 bit periods have passed without an occurrence of a string of

eight or more consecutive zeroes.
