1751 UMTS Annex A
Business VPN router for professional site connectivity with maximum flexibility and redundancy
-Integrated ADSL2+ and UMTS modem with HSxPA, EDGE and GPRS support
-5 IPSec VPN channels integrated; optional: 25 simultaneous VPN channels and hardware VPN accelerator
-Stateful- inspection firewall with intrusion detection/denial-of- service protection
-4 separate configurable switch ports
-Load balancing with up to 4 WAN connections
-ISDN interface for remote access, Backup or LANCAPI.
With its integrated UMTS/DSDPA modem, the ADSL2+ router LANCOM 1751 UMTS sets standards in flexibility and redundancy. Should a standard DSL connection fail at a site, branch office or subsidiary, automatic compensation is provided by a broadband UMTS/HSDPA or EDGE backup connection. Along with this unique level of high availability, the LANCOM 1751 UMTS is equipped as standard with 5 VPN channels (optionally 25), an integrated ADSL2+ modem and four separately configurable switch ports, so offering a huge variety of professional applications.
The SIM-card holder is easily accessible via the back cover and, by connecting an external UMTS antenna, indoor reception can be greatly improved. A real highlight: Anti- theft by ISDN self- callback and location determination by GPS!
More Security.
The integrated firewall with the latest security functions such as stateful inspection, Intrusion Detection and Denial-of- Service protection is supplemented by dynamic bandwidth management and comprehensive functions for backup, high-availability and redundancy. The integrated VPN gateway that fulfills the IPSec standard, and the optional hardware accelerator provide optimal security for connecting telecommuters and branch offices thanks to the high- security 3-DES or AES encryption and support of digital certificates.
More Management.
The management systems LANconfig and LANmonitor are included and offer not only cost- effective remote maintenance of entire installations and highly convenient setup wizards, but also full real-time monitoring and logging. What’s more, service providers benefit from the broad range of scripting methods and professional access with individual access rights for administrators via SSH, HTTPS, TFTP and ISDN dial- in.
More Benefits.
The versatile functions for address translation and routing allow completely different networks to be connected over common infrastructure. Existing networks at partner companies, home-office workstations or subsidiaries can be integrated into the VPN without problem. With the option of port separation and a separate address range, your own web servers can be securely separated from the LAN. The integrated ISDN interface allows remote field installations, dial-up access and CAPI featured functions such as fax services for all connected PCs.
More Certainty for the Future.
From the very start, LANCOM products are designed for a product life of several years. They are equipped with hardware dimensioned for the future. Even reaching back to older product generations, updates to the LANCOM Operating System—LCOS—are available several times a year, free of charge and offering major features. LANCOM offers unbeatable protection of your investment!
