mscVsServiceFailureReason

Module: Nortel-MsCarrier-MscPassport-VoiceMIB

OID (symbolic): Nortel-MsCarrier-MscPassport-VoiceMIB::mscVsServiceFailureReason

OID (numeric): 1.3.6.1.4.1.562.36.2.1.80.15.1.1

Node type: OBJECT-TYPE

Type: OCTET STRING

Access: read-only

Description: This attribute indicates the result of end to end negotiation with the remote end across the subnet.

If serviceFailureReason is undetermined, this Vs has not performed end to end negotiation with the remote end, and may or may not be up. serviceFailureReason is undetermined if this Vs just became enabled, if there is not enough available bandwidth to perform negotiation or if the remote end cannot perform negotiation with this Vs. If serviceFailureReason is none, end to end negotiation passed. If serviceFailureReason is mismatchedService, end to end negotiation failed because the remote end service is not a Vs. If serviceFailureReason is mismatchedVoiceEncoding, end to end negotiation failed because the local Vs Framer voiceEncoding does not match the remote Vs Framer voiceEncoding. If serviceFailureReason is mismatchedVoiceRates, end to end negotiation failed because the local provisioned ingress voice rates are not compatible with the remote end's egress capabilities or the remote provisioned ingress voice rates are not compatible with the local egress capabilities. If serviceFailureReason is mismatchedModemFaxEncoding, end to end negotiation failed because the local Vs Framer modemFaxEncoding does not match the remote Vs Framer modemFaxEncoding. If serviceFailureReason is mismatchedModemFaxRates, end to end negotiation failed because the local provisioned ingress modem and fax rates are not compatible with the remote end's egress capabilities or the remote provisioned ingress modem and fax rates are not compatible with the local egress capabilities. If serviceFailureReason is mismatchedCasSignalling, end to end negotiation failed because the local Vs Framer casSignalling does not match the remote Vs Framer casSignalling. If serviceFailureReason is mismatchedSignalBits, end to end negotiation failed because the local Vs Framer signalBits does not match the remote Vs Framer signalBits. serviceFailureReason is mismatchedSignalBits only if the local Vs Framer casSignalling is transparent. If serviceFailureReason is compDecodeFailed, end to end negotiation failed because the information received from the remote end was not recognized as valid data.

What is mscVsServiceFailureReason?

A bitmask explaining why end-to-end negotiation with the remote end of this VoiceService failed or hasn't happened, e.g. mismatchedVoiceEncoding, mismatchedVoiceRates, mismatchedCasSignalling, or mismatchedSignalBits; this is the field to check first when a voice circuit won't come up between two Passport nodes.
