being cheap is good, if it works

I'd a void both CCS and CCA. Our telephone line is ali, highly
unreliable, as the ali keeps fracturing in the IDC "jelly bean"
conectors. Spark installed some CCS "CW1308" (interior telephone
cable) from the master socket to router position, about 10 yards of
cable. Using that made a dramatic reduction in ADSL rate. Fortunately
I'd also specced a couple of (copper) Cat5e's as well, using one of
them no problem.
