The local E1 interface will not recover until the fault disappears at remote site.

.
The equipment will monitor the status of optical link, either transmitting alarm or receiving
alarm will be taken as an optical link fault. At the mean time, the Ethernet interface status
will change to link down and the E1 interface will be cut off. The 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.
3.2.3 E1 Remote Loop-back Test
“E1 remote loop-back” setup at local Ethernet Multiplexer
Note: when setup any kinds of loop-back at the local Ethernet Multiplexer, the “remote loop-back”
switch at remote Ethernet Multiplexer must be at default status.
When the module is at E1 remote loop-back status, the Ethernet data communication will not
be interfered.
3.2.4 How to Implement Remote Network Management
When the equipment is connected as the following topology, the remote network management can
be implemented.
