[cisco-voip] Adjusting attenuation on PRI's for echo...

[Ed Leatherman]

They are all 6608 T1 ports, i'm looking at the HTML page generated from the
particular ports, not seeing clock glitches and conseq sevErrSecs (assuming
those corelate to the stats that IOS spits out). If there are any CatOS
commands that are the equivalent, I havent been able to figure them out.

Been running for years with nary a problem till this past week. Clock source
is network, i haven't put in a service request yet for verizon to check
their side though.
