Chapter 1 General Introduction

1.1 Product Description

360*Phones rack device is a kind of point-to-point fiber transmission  rack device that developed based on special large scale integrated circuits of PDH fiber transmission in our company. It is with perfect alarm function that conclude a 360-channels phone convergence card.It can use 12 piece of 30 channels phones business card simultaneously in the Machine frame and 360-channels phones (optional),1~4 E1 and 1~4 100M linear Ethernet ports and SNMP Network management.it Provide back up power which make sure complete working function, high integration, low consumption, stable performance and convenient usage.
