Description - E1/Datacom Tester

This E1/Datacom Tester is a multi-functional, full- featured digital transmission system test device designed for the installation, testing, acceptance, and daily maintenance of digital networks. The E1/Datacom tester is able to perform 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. These capabilities make it ideal for filed use.
