Product Description

Introduction

This device  provides 1-4Channel E1 interface, 1Channel PCM digital hotline phone (optional). It is very flexible. It has alarm function. The work is reliable, stable, and low power consumption, high integration, small size.


Features

◆ Based on self -copyright  IC

◆ Modular wide dynamic optical detector

◆ 1 Channel PCM digital business phone (optional)

◆ The device provides master optical fiber interface and backup optical fiber interface, Dual Optical Port backup function ensures that the work will never break (optional)

 E1 interface comply with G.703, adopts digital clock recovery and smooth phase-lock technology

 When optical lose signal,it can detect the remote device is power off or fiber is disconnected,and indicates alarm by LED

 The local device can view the remote device working condition

 Provide command the remote interface Loop Back, ease line maintenance

 The transmission distance is up to 2-120Km without interruption

 AC 220V, DC-48V, DC24V can be optional

 DC-48V/DC24V power supply polarity detection function, Polarity-Free
