Dax DX-1821

Introduction

DX-1821 Modular Router can provide SMB enterprises and branch offices of large enterprises with a good price performance solution so as to meet their requirements of interoperability and deliver concurrent services of voice, video and data at optimal throughput.

DX-1821 Modular Router adopts modular design to provide flexible module configurations, making it more convenient to replace modules on site. With secure and reliable performance, DX-1821 adapts itself for small-to-medium sized enterprises, LAN-to LAN applications and multiple services.

High Port Density

The modular architecture of the DX-1821 integrated router allows variety of interfaces to be populated on a compact unit.

DX-1821 has one fixed sync/Async WAN interface (2Mbps), one open WAN slot for WAN Modules, one VoIP/ISDN slot, one console port and two 10/100Mbps Ethernet port. The DX-1821 allows mix and match of any available modules on a single Chassis. The encryption module can optionally be plugged into the Internal Bus Socket slot of the routing platform.

Security and Reliability

DX-1821 routers support IPSec and multiple protocols (such as L2TP and GRE) to guarantee comprehensive network security service as well as network performance. DX-1821 gives networks enhanced security to the network with the combination of IP packet filtering, Extended Access control list and Firewall.

High Network Availability

DX-1821 provides backup in multiple forms through ISDN or PSTN. The standard power supply module with CE certification can guarantee protection from surge, high-voltage, low-voltage and high current producing stable and reliable output.

QoS functions

IP networks will be required to provide QoS to satisfy the ever-growing business demands. DX-1821 routers can provide guaranteed bandwidth for various network services, with provision for queue management (such as PQ, FIFO and WFQ) and scheduling. DX-1821 offers a cost effective multifunction service platform for small-to-medium-sized enterprise applications.

Support for legacy networks

With support for features such as SNA, XOT, the DX-1821 Router can transport data received from legacy devices over the IP network.

Bandwidth Optimization

DX-1821 supports WAN optimization features such as dial-on-demand routing (DDR), bandwidth-on-demand (BOD), compression, filtering, and spoofing, thus reducing WAN costs.

Robust Design

DX-1821 Router is a standard 19' anti-electromagnetic-radiation chassis, which can be placed on a standard rack. With anti-electromagnetic radiation, shockproof properties and resistance to high/low temperature, DX-1821 provides stable and reliable performance.
