Product Configuration

High Performance
Driven by a powerful CPU MPC857T,110Mhz + Accelerated Processor the DX-1821 Router supports routing speed of up to 40Kpps providing advanced QoS, security, and network integration features that would be required in today’s evolving networks.

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 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 VPN module can optionally be plugged in 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.

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 soon 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 Routers can transport data received from legacy devices over the IP network.

Bandwidth Optimization

WAN optimization features such as dial-on-demand routing (DDR), bandwidth-on-demand (BOD), compression, filtering, and spoofing to reduce WAN costs are supported. 

Robust Design

DX-1821 Router is a standard 19’ anti-electromagnetic-radiation chassis, which can be placed on a standard rack. Due to its resistance to high/low temperature, anti-electromagnetic radiation and shockproof properties, DX-1821 can perform with improved stability and reliability.
