Hi I have a fiber mux that converts the signal into DS3 which is terminated on a cisco 6513, IOS 12.2(18)SXF14, WS-X6582-2PA module.



From the Mux to the Cisco its about 10 feet, I have no control of the mux fyi. Out of this Mux I have 3 DS3, two of them have a lot more C-bit/P-bit errors then I think should be there. On the other DS3 I have a 10 db anttenuator and im seeing some on occasion but alot less.



for example on the DS3s with no attenuator i see



Total Data (last 10 15 minute intervals):

0 Line Code Violations, 7 P-bit Coding Violation,

7 C-bit Coding Violation,

5 P-bit Err Secs, 0 P-bit Sev Err Secs,

0 Sev Err Framing Secs, 0 Unavailable Secs,

5 Line Errored Secs, 5 C-bit Errored Secs, 0 C-bit Sev Err Secs



but the DS3 with the 10db attenutor shows no errors



Total Data (last 10 15 minute intervals):

0 Line Code Violations, 0 P-bit Coding Violation,

0 C-bit Coding Violation,

0 P-bit Err Secs, 0 P-bit Sev Err Secs,

0 Sev Err Framing Secs, 0 Unavailable Secs,

0 Line Errored Secs, 0 C-bit Errored Secs, 0 C-bit Sev Err Secs



The same is true for a 24 hour period, i might see a few errors on the circuit with the 10 db attenuator but a lot more on the circuits with no attenutor.



Is there a way on the 6500 for me to see how much input signal power the PA is taking in so I can look up if its within the cisco DS3 PA specifications?
