The Avaya Secure Router 4134 (or SR-4134) in telecommunications and computer networking technologies is a device manufactured by Avaya that combines the functions of WAN Routing, stateful firewall security, Ethernet switching, IP telephony, and Microsoft mediation into one device. In addition to sharing many features with other routers such as VRRP, MPLS, and hot-switchable modules, the SR-4134 also guards against individual circuit failures, has the ability to recover from device failures in less than a second, and instantly restores bandwidth once a connection has been repaired. The system is very energy efficient, and can save the owner as much as 40% on energy total cost of ownership according testing by the Tolly Group. In July 2011 it was integrated with the Silver Peak WAN optimization appliance to optimize the performance of enterprise voice, video, and unified communications (UC), to ensure that remote users have fast and reliable access to all centralized applications.
This system is normally installed at a headquarters, regional or branch office and connected across the wide area network to another router or secure router at a regional, branch or other smaller remote location.
Several telecommunication modules for use with T1/E1 and DS3 ports (clear channel or channelized) will allow the system to operate over a wide range of telecommunication circuits. In addition to supporting up to seventy-two power over ethernet ports, the secure router 4134 can also support up to thirty-one T1/E1 ports, fifty-eight gigabit ethernet switching ports, or up to sixty-four FXO or FXS ports.
The SR-2330 has been validated as conforming to the Digital Signature Algorithm (DSA) specified in both FIPS 186-2 with Change Notice 1 dated October 5, 2001 and FIPS 186-3 dated June 2009, both titled Digital Signature Standard (DSS).
