In the activation of the operator's 2M line, it is necessary to determine whether the line's bit error rate and alarm indicators meet the activation conditions. In fault localization and handling, it is essential to assess whether there are issues with the line equipment.

The BER-1580 product is suitable for high-end applications such as operator 2M equipment maintenance, inspection, and testing of frame relay services for major telecom customers. It can perform bit error rate testing from 50 b/s to 2048 kb/s and supports 2M online testing, making it an essential tool for the daily maintenance, inspection, and activation of communication equipment. Supported interfaces include G.703, V.24/RS232, V.35, V.36/RS449, X.21, EIA-530/530A, and RS485/RS422. The BER-1580 also supports 2M jitter transmission/reception testing, 2M synchronous clock testing, and frame relay testing. The device additionally features an RJ45 network interface, supports complete TCP/IP protocols, and allows for online upgrades. Its unique remote testing function enables users to conveniently conduct real-time testing of the device via software in a Windows Chinese environment.
