Errors on a 2801 Router

Client has a C2801 router with the following interfaces:

2 FastEthernet interfaces
2 ISDN Basic Rate interfaces
2 ATM interfaces
1 terminal line
1 Virtual Private Network (VPN) Module
1 DSP, 8 Voice resources
1 cisco service engine(s)

 

Client is constantly having slow performance issues when trying to access the application from a remote VPN server.

I've had them isolate the line and I did a clear counters on all interfaces.

After 6 hours of no internal activity I had a look at the stats and there are 1190 total drops for the ATM interface and 0 drops for all other interface.

unfortunately I cannot perform a ATMloop test as I'm not in the vicinity of the router (it's in the northern territory of Australia and I'm in the southwestern  of Australia).

Before I have the interface exchanged I would like to get some input from others first to either confirm my findings or dispute it.

Any decent ISP, when they are furnished the above output, will know it's a bad line.  

 

Noise:  Above 20 dB is better. 6.5 dB is BAD!

Attenuation:  30 dB and below is better.   Attenuation value of 44 dB is BAD.

Another thing, your firmware is very, very old.  You really need to upgrade them.  

 

Go HERE for instructions on how to upgrade the firmware and where to get the firmware.
