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

https://dcc.ligo.org/cgi-bin/private/DocDB/ShowDocument?.submit=Number&docid=T1200123&version=

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.
