A detailed description of the CDS front ends controlling BSC8 at the time of the fiber breakage has been submitted to DCC as document: LIGO-T1200123

there is sufficient detail in this report that I did not want to submit a huge alog entry. Later I'll also submit a tar file of the front end models and related files covering this time period.
