  • Method and system for testing a sonet network element
    Patent number: 5455832
    Abstract: Method and system are described for testing SONET network elements (NE) against various SONET logical layer criteria or standards. A "basic" signal is developed or generated to meet many of the criteria in order to minimize the number of alarms or abnormal conditions reported by the NE. Simple procedures are provided to modify the basic signal. The test signals are utilized to test a network element's ability to detect and respond to incoming signal failures and maintenance signals, its payload mappings, and its use of various overload bits and bytes.
