ONFIGURING
Avidia systems use Automatic Protection Switching (APS) to switch ATM traffic from the main
SONET channel (the working channel) to a secondary SONET channel (the protection channel)
when a failure occurs. This redundancy enables service to continue despite failures on the
working SONET channel. See

You configure APS from the ::aps=> prompt. From the ::root=> prompt, type the
following command then press
