Overview

Introduction

MSR 20 Series Routers were self-developed by our company. for use on enterprise-level networks.
Depending on the network size, MSR 20 Series 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 Series Routers are suitable for the application on the carrier-level
networks, such as telecom management networks and billing networks. MSR 20 Series 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 series includes the following models:
MSR 20-20
MSR 20-21
MSR 20-40

Router Model and Structure

The MSR 20 Series 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.
