SYSTEM MESSAGES
(6) Receiving Path Failure/Receiving Path Error
Abnormal state is detected in the process of multiplexing the “Receive” signals. To restore this, perform
the following:
STEP 1 Initialization of SDT card (distant node)
Initialize the SDT card in the distant node, and observe the situation. If the fault is not restored,
proceed with STEP 2.
STEP 2 Initialization of SDT card (self-node)
Initialize the SDT card in the self-node, and observe the situation. If the fault is not restored,
proceed with STEP 3.
STEP 3 Replacement of SDT card
It cannot be confirmed which node side (self-node or distant node) is faulty. By referring to
Chapter 4, Section 3.3.3, SDT Card Replacement Procedure, first replace the SDT card only in
one of the nodes. When the fault does not recover, then also replace the SDT card in other side
of the nodes.
(7) Pointer Failure/Sending Path Failure/Sending Path Error
Abnormal state is detected in the process of multiplexing the “Send” signals. To restore this, perform the
following:
STEP 1 Initialization of SDT card
Initialize the SDT card in the self-node, and observe the situation. If the fault is not restored,
proceed with STEP 2.
STEP 2 Replacement of SDT card
By referring to Chapter 4, Section 3.3.3, SDT Card Replacement Procedure, replace the SDT
card in the self-node with a spare.
