Sample APS Application:
MC-APS for ATM SAP with ATM VPLS Service
In Figure 14, service router A is connected to the ATM switch or 7670 through an OCx ATM 1
link. This link is configured as the working circuit. Service router B is connected to the same ATM
switch or 7670 through an OCx ATM 2 link. This link is configured as the protection circuit.
Figure 14: Multi-Chassis APS Application
Communication between service routers A and B is established through link 3. This link is for
signalling. To guarantee optimum fail-over time between service routers A and B, link 3 must be a
direct physical link between routers A and B.
