2.1Overview
L54 series of PDH digital microwave radios, and integrated design
incorporating high & new technology such as FPGA, ASIC and digital signal processor (DSP).
The L54 is designed for short-haul, high-reliability, easy-toinstall, and low-cost point-to-point
communication links. Applications include PCS/PCN micro-cell fixed network infrastructure, cellular
back-haul interconnections. And now the L54 has been used in applications such as military and
private networks for government, educational institutions, banks and commercial organizations.
The L54 is designed for data rates including 4x 2.048 Mb/s (4E1), 8x 2.048 Mb/s (8E1), 16x
2.048 Mb/s (16E1), 10/100BASE-T+ 1/2/4 E1 (14MHz or 28MHz) in protected and unprotected
configurations.
Indoor Units (IDUs) are muilti fuctional; configure flexial, small, and reliable, support capacities
including 4E1, 8E1, 16E1, 10/100BASE-T+1/2/4E1. And IDU supports 2 auxialy data channels, a
phone channel, a 10BASE-T and RS232 network management channel. Meanwhile, we can get the
BER, RSL and working status of equipment, and control the working status by NMS or LCD panel.
