Then it would appear that RTRA may have bad transmit, or the transmit
through the carrier (NEON?) is bad. Recall that if the transit through the
carrier was bad, the carrier would be seeing Line errors at some point in
their network. Since this is less likely than there being a bad transmit
from RTRA, have the carrier check the Rx port on their LTE. They are likely
seeing errors.

Subject: Re: SONET-4-ALARM everyday
thank you all who responded to my email.
to clarify my configuration. I have
RTA ----- NEON ---- RTB
RTA logs SONET-4-ALARM everyday. MIB shows.
sonetFarEndPathCurrentESs.5 = Gauge: 122
sonetFarEndPathCurrentSESs.5 = Gauge: 0
sonetFarEndPathCurrentCVs.5 = Gauge: 122
sonetFarEndPathCurrentUASs.5 = Gauge: 0
RTB does not log SONET-4-ALARM at all, MIB shows.
sonetPathCurrentESs.2 = Gauge: 122
sonetPathCurrentSESs.2 = Gauge: 0
sonetPathCurrentCVs.2 = Gauge: 122
sonetPathCurrentUASs.2 = Gauge: 0
sonetFarEndPathCurrentESs.2 = Gauge: 1
sonetFarEndPathCurrentSESs.2 = Gauge: 1
sonetFarEndPathCurrentCVs.2 = Gauge: 81
sonetFarEndPathCurrentUASs.2 = Gauge: 0
I do not see any errors on sonetSectionCurrent.., sonetLineCurrent.. and
sonetFarEndLineCurrent.. .
any idea?
