Configuring Fault Propagation
The fault propagation mechanism propagates the E1 and T1 link defect conditions
to the 100BaseFx port. When the fault propagation is enabled, the Ethernet port
is disconnected if one of the following events is detected on the TDM interface:
• Loss of signal (LOS)
• Remote defect indication (RDI)
• Alarm indication signal (AIS).
Alternatively, you can disable propagation of any of the supported conditions to
the Ethernet port.
You can also specify the wait-to-restore (WTR) time (the time period MiTOP-E1/T1
waits before reconnecting an interface once the failed interface is restored).
³ To configure fault propagation:
1. From the System menu (Configuration > System), enable or disable fault
propagation.
2. When fault propagation is enabled, select Fault Propagation to display the
relevant menu and configure the following parameters:
 LOS:
 Enable (LOS on the TDM link is propagated to the Ethernet interface)
 Disable (LOS on the TDM link is not propagated to the Ethernet
interface)
 RDI:
 Enable (RDI on the TDM link is propagated to the Ethernet interface)
 Disable (RDI on the TDM link is not propagated to the Ethernet
interface)
 AIS:
 Enable (AIS on the TDM link is propagated to the Ethernet interface)
 Disable (AIS on the TDM link is not propagated to the Ethernet
interface)
 Fault Propagation WTR (Wait-to-restore time in seconds): 0–3600;
0 disables the WTR.
