Industrial / Rugged ADSL 2+ Router – 6401

6401-Industrial / Rugged ADSL 2+ Router

The Case Communications 6401  Industrial / Rugged ADSL 2+ Router has been designed to operate reliably and securely without fans in harsh conditions from -200C to +700C.



The Case Communications 6401 Industrial / Rugged ADSL 2+ Router is supplied with 4 x 10/100Mbps Ethernet ports, supports ADSL2+ Annex ‘M’ and is equipped with high levels of security. Therefore the 6401 is the ideal router for UTMC, (Urban Traffic  Management Control) monitoring or controlling telemetry systems, or any application requiring a secure street hardened router.


Operating Temperature

The Case Communications 6401 is capable of operating from an AC mains or DC Power source ranging from 12vdc  ~ 72vdc. Therefore it can powered by batteries or an AC to DC power adapter.

Ability to solve ISP Reliability Issues

At some locations the Internet service hangs and the ISP requests you reboot your router to restore service.

Because in an industrial unmanned environment this is not always practical (because  industrial routers tend to are operate in unmanned locations), consequently the 6401 has a 'Health Check Watchdog Timer' which checks the Internet connection and restarts the line automatically should the Internet Service hang.


Because the 6401 is carrying sensitive information over a public network IP Security in the form of IPSec  ensures secure tunnels can be established back to central site. The 6401 Industrial ADSL Router has a choice of 3 DES and AES Encryption modes,in addition by using FQDN we can provide IP Sec from a dynamic IP Address


Furthermore the 6401 is managed locally and remotely via a user friendly  Browser, CLI or via a network management system running  SNMP (Simple Network Management Protocol), with up and downloading of the units configuration to an FTP Server, making it quick and easy to install and configure the 6401.


A built in Firewall allows managers to block incoming traffic and filter out any unwanted traffic.


The 6401 supports multicast, which is most commonly used in the application of streaming data, and IP television. In IP Multicast the implementation of the multicast occurs at the IP routing level.

IGMP is an integral part of the IP Multicast specification, and it is analogous to use IGMP for Unicast connections. IGMP can be used for online streaming of video and gaming, and it allows more efficient use of resources for these kind of applications.
