ATM OAM
Circuit Emulation PICs provide ATM support for the following OAM-FM cell types:
- F4 AIS (end-to-end)
- F4 RDI (end-to-end)
- F4 loopback (end-to-end)
- F5 loopback
- F5 AIS
- F5 RDI
The following sections describe:
VP Pseudowires (CCC Encapsulation)
In the case of ATM VP pseudowires (all VCs in a VP are transported over a single N-to-one mode pseudowire), all F4 and F5 OAM cells are forwarded through the pseudowire.
Port Pseudowires (CCC Encapsulation)
Like VP pseudowires, with port pseudowires, all F4 and F5 OAM cells are forwarded through the pseudowire.
VC Pseudowires (CCC Encapsulation)
In the case of VC pseudowires, F5 OAM cells are forwarded through the pseudowire, while F4 OAM cells are terminated at the Routing Engine.
