802.3ah - IEEE 802.3-2005
802.3ah Ethernet Link OAM, or IEEE 802.3-2005, was originally developed for EFM applications to monitor the health of a single Ethernet link – typically the connection between an end point, such as customer premises, and the Metro Ethernet network edge. In addition to defining Ethernet delivery over copper, fiber and PON (Passive Optical Network) media, IEEE 802.3-2005 specifies the following link monitoring OAM procedures:
-
Discovery
-
Remote failure indication, including link fault, dying gasp and other critical event indications
-
Remote loopback testing
-
Link performance monitoring
-
Management Information Base (MIB) variable retrieval
-
Organization-specific functions
802.3ah over Copper
802.3ah over Fiber
802.3ah over DSL
RAD’s EtherAccess® demarcation devices feature a complete Ethernet OAM package, including 802.3ah Ethernet Link OAM support. They provide carriers with tools to ensure complete control over their access links and to reduce maintenance costs by avoiding expensive truck rolls to locate and contain faults. The EtherAccess demarcation devices offer consistent 802.3ah support over copper, fiber and DSL media.
