Analyzer option

An Extended Overhead Analysis option is offered for the ant-20 Advanced Network Tester. The option enables testing of the aps (automatic protection switching) function in sdh and sonet systems with a ring or linear structure. Various events can be set as start criteria. The analyzer then compares the result (in milliseconds) with the limit values in accordance with itu-t or ansi, deriving pass/fail information.
