GAO Tek E1 Datacom BER Tester



E1 BER Tester is a handheld, compact testing unit that combines the testing capabilities of E1, Datacom and IP PING all in one. It is designed for the performance evaluation of Digital Transmission Network, Digital Data Network (DDN) and some private communication networks as well. This tester fulfills the demands of equipment installation, engineering verification and daily maintenance and troubleshooting of Ethernet connection. It mainly provides the following functions: HDB3 and AMI line codes, 75Ω (Unbalanced), 120Ω (Balanced) and high impedance>2kΩ(option), out-of-service framed/unframed testing (“TX/RX” mode) that monitors signal loss, AIS, frame loss, remote alarm, remote MF alarm, CRC, MF Loss, CAS MF Loss, pattern loss alarms and errors such as BIT, Code, FAS、CRC-4 and E-BIT. The other type of testing that the BER Tester offers is the In-service framed/unframed testing (“RX HI-Z” and “Through” mode) which include, Rx Hi-Z and through mode testing, code, FAS, CRC-4 and E-BIT BER testing, FAS/NFAS, MFAS/NMFAS, timeslot activity monitoring and CAS and CCS signalling monitoring. Other functions that aids field technicians and engineers in completing their tasks are frequency and offset measurement, real-time transmit circuit open/short indication, auto-configure functions such as E1 frame format, BERT pattern, the timeslots carried BERT pattern automatically detection and setting for E1 testing. This efficient and reliable tool is the perfect solution for any telecommunication technician or engineer.
