dahdi_maint -s <spanno> will provide the error counters that are available for the span. i.e.: ]# ./dahdi_maint -s 1 Span 1: >FEC : 0: >CEC : 0: >CVC : 0: >EBC : 0: >BEC : 0: >PRBS: 0: >GES : 0: You can see verify if the drivers are adjusting the gain on a channel with the dahdi_diag tool. 'make dahdi_diag' in dahdi_tools in order to build it, since it's not built by default. Then: ']# dmesg -c > /dev/null && ./dahdi_diag 1 && dmesg -c' And look for the gainalloc output to see if DAHDI is gaining the channels.
