ZS-OS155-42 STM-1 SDH/MSTP Access Device Fix 42E1

 

 

Overview

ZS-OS155-42 is the STM-1 level Synchronous Digital Hierarchy (SDH) system, and fully complied with ITU-T standard. It can be used as a Terminal Multiplexer (TM) or an Add-Drop-Multiplexer (ADM) to build point-to-point, ring and chain transmission network.

Features

l         High integrated

n         Chassis dimensions (1U) : 481 x 305 x 44 ( W x D x H)

l         Single-card design

n         Single card can provide  42  E1 interfaces

l         Standard element timing

n         Supports ITU-T G.813 standard NETF, switching automatically between multi time sources

l         Flexible engineer Order Wire

n         Provides Engineer Order Wire (EOW) interface (two-line model), with group call and dial functions

l         Powerful network capacity

n         Supports point to point, chain and ring networks,

n         working with ZS-OS155-Shelf can build tangency ring, tributary ring and some other more complex networks

l         Convenient Management

n         Support Ethernet and RS232 management interface

n         Support using special E1 port for management

n         Support using D1-D3 or D4-D12, support DCC transparent transmission.

l         Multiple power supply Modes

n         Privide 220V AC or access -48V DC to meet diverse requirements.
