ZYEQ-120ES

INTRODUCTION

ZYEQ-120ES is an integrated optical-electrical fiber transmission device based on the VLSI ZYIC-016. It is designed with 120-channel transmission capacity in 4 E1 channel. Two of 4E1 channel can transmit V.35 or 10 Base-T Data by using built-in converters. It is suitable for small capacity switches networks, user ring networks, mobile base stations, private networks, DDN networks, etc.

MAIN FEATURES

•	E1 G.703 interface remote loop-back testing available.

•	2 of 4E1 channels can connect interior protocol converters which perform V.35/E1, V.35/FE1, 10BaseT/E1, 10BaseT/Fe1; therefore become V.35 ports or Ethernet ports.

•	1 service-phone channel.

•	Power supply: DC-48V or AC 220V, in some extraordinary case, ±24V available too.

•	Local and remote status alarming.

•	Local or remote management interface optional.
