Edge 8500Intelligent Edge™ - Multi-Service Edge Router and SBC with Modular Gateway Choices High quality, secure bandwidth is the lifeblood of business, especially as organizations move business and communications applications to the cloud. Collaboration, streaming video, data storage, and data back-up services all require greater bandwidth to operate effectively. Service providers and business customers need an Intelligent Edge device that cost effectively delivers, manages, protects, and monitors high-capacity broadband connections. Ribbon's Edge 8500 delivers superior value by offering a common platform that includes: • A full-featured, multi-tenant, edge/provider-edge (PE) data router with up to 10 Gbps of throughput • Market leading Session Border Controller (SBC SWe Edge) services to protect communications traffic • Modular gateway choices for analog line and station ports, (FXO/FXS) and PRI (T1/E1) • Option RedHat Operating System (OS) variant for Federal Information Processing Standard (FIPS) 140-3 compliance • High Availability (HA) option for SBC services (Requires R25.1 software) • Microsoft Teams Survivable Branch Appliance (SBA) integration and Zoom Phone Local Survivability (ZPLS) compliance Too often organizations, especially multi-site organizations, are forced to choose between consumer-grade solutions that are not robust or pricier industrial-grade solutions Ribbon's Edge 8500 is different. It offers 2.5, 5, or 10 Gbps of routing throughput, with Session Border Control (SBC) options, including high availability options, and modular telecom gateway choices, all in one intelligent edge device. It leverages Ribbon's proven SBC SWe Edge software to assure communications security. The Edge 8500 is also designed for what comes next. It includes VNF (Virtual Network Function) support to deliver uCPE-based services (centrally managed and strategically located at the edge of a customer's network) and an Application Services Module (ASM) to run additional services. (Note that the ASM module requires R25.1 or later software.). It's also avaialable with a RedHat OS for government or critical infrastructure provider that require or desire FIPS 140-3 compliance. Key Connectivity Choices for Edge 8500 • Robust routing with data rates of up to 10 Gbps • Multihoming with BGP for resilient/diverse links • All physical interfaces (10 ports) can be provisioned as • WAN or LAN (No fixed function for interfaces) • SBC capacity of up to 960 concurrent calls Certified for Popular Cloud Solutions

Across the globe traditional PSTN services are being discontinued and/or prices are being increased on traditional analog or PRI- based services to encourage organizations to migrate to IP-based connectivity. While this makes sense strategically, it doesn't address the tens of millions of traditional devices (elevator phones, paging systems, alarm systems, door phones, etc.) that need to be maintained. Not to mention the need to replace traditional PBXs if they don't support SIP Trunks. Ribbon's Edge 8500 offers an ideal solution. Its modular design can be configured to meet individual site requirements....

The Edge 8500 leverages Ribbon's two decades of experience building Session Border Controllers (SBCs). The Edge 8500 runs Ribbon's market leading Session Border Controller Software Edition, Edge (SBC SWe Edge) as a virtual network function (VNF). In simple terms, the SBC acts as firewall for voice traffic, assuring that bad actors can't use the voice path to enter the network, eavesdrop on calls or launch a denial-of-service attack that disrupts communications. The SBC SWe Edge software can be licensed for up to 960 concurrent sessions (simultaneous calls) and can be deployed in High Availability...
