Overview

Introduction

MSR 20 Routers were self-developed for use on enterprise-level networks. Depending on the network size,

MSR 20 Routers can be either core routers on small and medium enterprise networks, or access routers

for network branches on some large-sized enterprise networks. Therefore, MSR 20 Routers are suitable

for the application on the carrier-level networks, such as telecom management networks and billing
networks. MSR 20 Routers adopt modular design and provide a wide range of optional smart interface

cards (SICs). The MSR-20, MSR 20-21 and MSR 20-40 are available with AC-powered units.
Currently, the MSR 20 includes the following models:

MSR 20-20

MSR 20-21

MSR 20-40

Router Model and Structure

The MSR 20 Routers include MSR 20-20, MSR 20-21, and MSR 20-40. These three models are similar

in chassis structure and layout. All of them can be put on the tabletop and can be mounted in 19-inch

standard racks. The following subsections will give you more details about these three models.
