[cisco-voip] How do I diag bad ports on a VG224?

[Tim Reimers]

I have a VG224 with four ports that have no dialtone on them.
 
they all used to work, and now have either silence or a loud hum on
them.
 
I've detached the station side wiring from the 66-block, and the hum
persists.
 
Ports 2/8 through 2/11 are dead, and I'm suspicious of lightning or
something like that, since we've had some other events in the last few
weeks.
 
But I don't see anything in post like the errors you'd  you'd normally
see in a Catalyst switch with a blown ASIC 
(the sort of thing that takes down four ports all at one time)
 
Externally, this VG is acting like four ports are blown, but not showing
any errors?
 
Anyone? Got some hardware troubleshooting methods and processes for the
VG 224 series of gateways?
 
I'd like to have some sort of cut-&-paste info to put into a TAC case
beyond the serial number of the unit.
