| | The DTA-SDH/ 155 transmission analyzer is a palm, graphic, color-LCD SDH/ PDH measuring
instrument designed for field use in analysis and maintenance of STM-1( 155Mbps) and E1( 2.048 Mbps)
lines. The DTA-SDH/ 155 has optic and electric port, evaluate and analysis result according to ITU-T
G.821, G.826, G.828, G.829, M.2100, M.2101. Its easy operation, light weight, long working hours, low
price, may be the ideal solution for field work.
