14.4.97 RAI
•
Not Alarmed (NA) (Condition)
The remote alarm indication condition (RAI) signifies an end-to-end failure. The error condition is sent
from one end of the SONET path to the other.
RAI on the XTC card indicates that far-end node is receiving a DS-3 AIS.
Procedure: Clear the RAI Condition on XTC-28-3 Cards in C-bit Format
Use the AIS procedure to troubleshoot the far-end DS-3 node for RAI.
14.4.98 RCVR-MISS
•
Major, Service-Affecting
A facility-termination equipment receiver missing (RCVR-MISS) alarm occurs when the
facility-termination equipment detects an incorrect amount of impedance on its backplane connector.
This usually occurs when a missing receive cable on the XTC-14 port or a possible mismatch of
backplane equipment, for example, an SMB connector or a BNC connector is connected to an XTC-14
card.
Caution
Always use the supplied ESD wristband when working with a powered ONS 15327. Plug the wristband
cable into the ESD jack located on the lower-right outside edge of the shelf assembly.
Note
DS-1s are four-wire circuits and need a positive (tip) and negative (ring) connection for both transmit
and receive.
