Overview

 
Business Secure Router 252, designed specifically for small and mid-sized businesses, is a converged broadband access router that provides a high-speed, always-on secure connection to the Internet through a built-in ADSL2+ modem that provides 24 Mbps downstream and 1 Mbps upstream data rates. With Business Secure Router 252, all you require to access the Internet is high-speed DSL (digital subscriber line) service from an Internet service provider.

Provides a high-level of security through standard-based VPN, firewall, authentication, and encryption
Delivers Quality of Service through packet differentiation based on priorities
Ensures easy installation through an intuitive, user-friendly web Graphical User Interface
Offers simplified operation, administration and maintenance through the Nortel Business Element Manager

Offer enterprise-class data and security at a small-business price - Any number of routers can connect your data network across locations, or to the Internet through cable modems or DSL lines. What makes the Business Secure Router 252 superior to other products is the high degree of security and the intelligent QoS it offers - especially at such an attractive price.

Support a full range of voice and data services - The Business Secure Router 252 supports all the voice and data features of your Nortel communication servers and IP phones. Hundreds of calling features, voice messaging, Unified Messaging, Automated Attendant, Contact Centers - these capabilities and more can span multiple locations.

Prioritize your most important services - Some data services, such as VoIP, are sensitive to even the slightest delay, while others, such as e-mail or fax, can receive secondary treatment if necessary. That’s why Business Secure Router 252 supports class-based QoS.

Create secure networks over the public Internet - Virtual private networks (VPNs) enable you to use the Internet as your own private network. The Business Secure Router 252 supports up to 10 secure IPSec tunnels simultaneously for for VPN-connected devices that use the IPSec security protocol.

Prevent hackers and viruses from getting into your network - A built-in firewall provides a perimeter defense to guard your business network against unauthorized users, such as those trying to “spoof” or pretend to be legitimate users.

Increase security and flexibility in IP addressing - Network Address Translation (NAT) converts internal IP addresses into your public IP address and vice versa. By hiding your private IP addresses from the world, NAT provides an extra layer of security. NAT can also be used to share static addresses across a group of users, who need exclusive, but temporary, use of a static IP address. Since static IP addresses can be costly, this can translate into hard cash savings for your company.

Easy to set up, use and manage with Nortel Business Element Manager - We designed the Business Secure Router 252 to be a plug-and-play. A configuration wizard guides you through the simple steps of setting up the router and going live. You can activate, set up and manage applications from any workstation that has LAN or Web access, using Nortel Business Element Manager, browser-styled management software with graphical interfaces and step-by-step wizards.
