Basic Concepts

The submarine cable line monitoring system monitors the working state of the submarine cable lines and manages the line test data, to provide data for fault location and submarine equipment maintenance. Mastering basic concepts of the submarine cable line monitoring system helps you monitor and manage the submarine cable lines by using the submarine cable line monitoring equipment in an effective manner.

Basic concepts of the submarine cable line monitoring system include the following:

• Submarine Cable Line Monitoring System
  The SLM 1630 provides the line monitoring function for the submarine communication system.
• Submarine Cable Line Test Modes
  The submarine cable line monitoring function is used to monitor status and locate faults of the submarine equipment. The SLM 1630 provides two test modes for submarine cable lines. The modes include in-service mode and out-of-service mode.
