LEDR Fractional T1/E1 Interface
Product Overview
The new subrate LEDR microwave radio family provides full duplex, scalable bandwidth and capacity from 64 kbps to 768 kbps in a 200 kHz channel. These radios are designed to operate in a point-to-point environment with a wide range of applications. They are especially effective for telecommunications access and transport links, wireless backbones for SCADA systems,and for use as backhauls to extend existing telecommunication channels. The subrate LEDR microwave radio is designed to connect to any industry standard EIA-530, V.35, fractional T1 or E1 source.
