We hv one STM-1 link provided by service provider.This has been configured
in channelised E1 links. I got two optic pair from service provider.
Further two optic links has been provided by same service provider from the same MUX as
redundant link to each other. And service provider has configured these two optic links in their ring,
such that if one optic goes down then the STM-1 will be served by another optic link.
Now at router we have two STM-1 module, one optic link is connected to first
STM-1 module and all channelised configuration done in it.
Problem: How to configure another STM-1 card to serve the network in case
first optic link goes down. ( As a hot standby)
Note : Also if i make both STM-1 card UP then all remote sites appear twice in the router.
