All Versions AAL2 External AIS
Count
bearerAal2ExtAISCnts This object contains the number of external AIS
aal2 Type3 packets received. External AIS - is a
Alarm Indication Signal associated with a
maintenance alarm detected on a defective
maintenance span, that is transmitted in the
direction of the defect as a substitute for normal
signal. The purpose is to show the downstream
entities that a defect has been identified and to
prevent other maintenance alrams consequent to
this first defect. External AIS bit stream is
represented by an all 1's signal. Ref - ITU-T Rec.
M.20 sec. 5.4.2 a
All Versions AAL2 External RAI
Count
bearerAal2ExtRAICnts This object contains the number of external RAI
aal2 Type3 packets received. External RAI - is a
Remote Alarm Indication signal that is transmitted
upstream from an entity that has detected defects
persisting long enough to constitute a received
signal failure. Its purpose is to report in the
backward direction that there is an interruption of
service in the forward direction. Ref - ITU-T Rec.
G.704 section 2.1.3.1.3
All Versions AAL2 Conn AIS
Count
bearerAal2ConnAISCnts This object contains the number of external Conn
AIS aal2 Type2 packets received. External Conn
AIS - is a Alarm Indicating Signal transmitted in
the downstream direction from the AAL type 2
connecting point that first detects a defect affecting
the AAL type 2 connection; this includes defects
indicated by lower layers. Ref - ITU-T Rec. I.610
sec 6.2.2.1.1.1
All Versions AAL2 Conn RDI
Count
bearerAal2ConnRDICnts This object contains the number of external Conn
RDI (Remote Defect Ind.) aal2 Type2 packets
received. External Conn RDI - is a signal
transmitted upstream by an AAl type 2 endpoint
that is in an alarm state as the result of having
received an AAL type2 connection AIS or having
detected a defect that affects the AAL type2
connection.
