SDH 155M MSTP(standalone)----Multi-optical Access Platform

SDH-155M  Mstp         

1. Introduction

This series take SDH technology as the core, and have the function of the unified access, convergence, exchanging and management of TDM service and bandwidth data. It’s the comprehensive access fiber transmission platform facing the traditional telecom service and bandwidth data application, simultaneously adapt to the integration tendency of data service in metropolitan area network and the various private network.

The standalone SDH is quite flexible, STM-1/STM-4 SDH, 155M/622M double optical ports backup function; provides 63 or 4*63 channels E1 with the plug-in way, and has four kinds of subsidiary card to be selected, Ethernet, V.35, EOS and E1 card. The customers can choose the corresponding port according to your requirements. The equipment realizes SNMP network management, and adopts the double optical ports, 1+1 protection mode.
