2.6.153 MSSP-SW-VER-MISM

An RFI occurs when the ONS 15600 SDH detects an RFI in the SDH overhead because of a fault in
another node. Resolving the fault in the adjoining node clears the MS-RFI condition in the reporting
node.

Clear the MS-RFI Condition

Log into the far-end node of the reporting ONS 15600 SDH.
Step 1
Determine whether there are other alarms, especially the
Step 2

2.6.154 MS-SQUELCH-HP

The Multiplex Section Ring is Squelching High-Order Path Traffic condition is raised on an STM-N
facility. If the node failure scenario includes the source node, the node that drops the signal will squelch
traffic. The condition resolves when the node recovers.
This condition is raised with an NA severity by default. However, it indicates that traffic is squelched
due to node failure (traffic outage). Traffic outages can be caused by different problems, such as multiple
LOS alarms, MS-AIS, or node power outages. MS-SQUELCH-HP is symptomatic and indicates that the
user must investigate which node in a ring is being isolated and what is causing the node isolation.
