Locating and Correcting Cable Disconnections
Section 10-4
The following diagram shows which interface is used to receive data from the
other nodes when the cable between nodes 3 and 4 is disconnected or bro-
ken.
No data is received through node 3’s SL2 interface or node 4’s SL1 interface.
When a node detects that no data is being received through one of its inter-
faces (such as nodes 3 and 4 in this example), it notifies the polling node that
a “network cable disconnection” has occurred.
