Multi-functional E1/Datacom Tester
GAO A0020006

Overview – Multi-functional E1/Datacom Tester

This full-featured E1/Datacom Tester is designed for the installation, acceptance testing and daily maintenance of digital networks. The E1/Datacom tester performs channel tests, alarm analysis, fault location and signal analysis. In addition, this tester provides various protocol converters with one-way and bi-directional bit-error-rate (BER) test functions.
