2. Overview
Basically, this document provides multi-chassis support for PON access
Unique characteristic of PON trunk protection
In trunk protection, downstream optical signal is not available on the protection link
End to end protection mechanisms such as ITU-T G.8031 does not work as APS protocol runs on the protection path
Extend ICCP to support synchronization of PON state and use PW redundancy to synchronize PW switchover
Why MPLS and PON functionality are converged in a single equipment?
Why type-B is the most interested scenario?

DSL tree builds on existing subscriber lines
PON further provides a section of aggregation

5. Comments & questions on V.02
Any deployment of Type-B PON protection?
Yes, we see quite a few real deployments of type-B PON protection in carrier networks around the world, and many more SPs have shown their interests in its future deployment.
Like to see more access technologies are covered, such as DSL and Ethernet
For the moment, we focused on PON since it is the immediately needed, but contributions on other access technologies are greatly welcome.
