Can someone on the list shed some more light on this?  Verizon reports the 9
linear oc-48s are impacting 173 ds3s, 3 oc3cs, and 14 oc12cs. There is 1
unprotected oc192c down for TOT-A. OTDR readings from Baltimore place the
break at 36.4 miles towards Washington. Additional OTDR readings from Laurel
toward Washington indicate cut at 16.25 miles.

Are the two OTDR readings consistent with one break on a shared segment
of the DC-Balt and DC-Laurel runs, or is some cable-splicer having a *really*
long day ahead?
