Displays whether the checksum fault alarm is or .

To protect against degradation in the non-volatile storage and potential errors in transfer, the module management interface defines a few registers to let module manufacturers save checksums or check codes. Each checksum or check code is assigned for a small-sized datum derived from a block of digital data. The algorithms of calculation for checksums or check codes are defined by management interface specifications of form factors. For example, the checksum or check code shall be the low order 8 bits of the sum of the contents of that small-sized datum. Prior to using the stored information, module users calculate the checksums or check codes again using the same algorithm. If the results are different from those saved in checksum bytes by module manufacturers, checksum fault alarm is triggered. A Checksum fault means that the content of the small-sized datum covered by this checksum is corrupted or changed.

Some transceivers have Clock and Data Recovery (CDR) circuits at the transmit side.

The feedback circuit of PLL eventually locks the local oscillator on to the phase and frequency of the incoming signal. The PLL maintains that lock by continuously monitoring the received signal. If the lock cannot be maintained, the Loss of Lock (LOL) alarm is generated.
