ZYEQ-120MS+

INTRODUCTION

ZYEQ-120MS+ is Mini size of ZYEQ-120ES and is also 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

•	Large scale ASIC utilized, low power consumption and high reliability.

•	Compact physical construction, Desk-top Mini model.

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