Ethernet interface and E1 interface will not recover until the optical interface
recovers.
The fault-pass-through capability is designed for users who have particular requirements.
When it is disabled, any fault at remote site and at optical interface has nothing to do with
local interfaces; all the interfaces of local module will be open.
In order to avoid misunderstanding, users are advised to use it cautiously. The factory
default status is disabled.
