Frequently Asked Questions
What is a session border controller and why do I need one?
A session border controller (SBC) is a network security appliance that manages, secures, and controls IP communications between your private network and the public Internet or PSTN. The Ribbon SBC 5400 protects against threats, normalizes SIP protocols, manages call routing policies, and ensures quality of service for voice and multimedia traffic.
How does the dual chassis high availability configuration work?
The dual 5400-2GB chassis setup provides redundancy and failover protection, ensuring continuous service availability. If one chassis experiences issues, the other automatically takes over, maintaining up to 2000 concurrent sessions without service interruption—critical for enterprise communications infrastructure.
Can the Ribbon SBC 5400 handle IPv6 and IPv4 traffic simultaneously?
Yes. The SBC 5400 includes built-in IPv4-IPv6 interworking capabilities, allowing seamless communication between legacy IPv4 networks and modern IPv6 deployments. This ensures compatibility across diverse network environments without requiring separate infrastructure.
What traffic volumes does the SBC 5400 support?
The Ribbon SBC 5400 scales from 2GB to 10GB of multimedia traffic capacity, supporting tens of thousands of concurrent IP-telephony sessions depending on licensed capacity. The dual 5400-2GB configuration in this package is optimized for mid-to-large enterprise deployments requiring high availability.
