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 protects, mediates, and controls IP-based real-time communications. The Ribbon SBC 5400 secures your voice and video traffic, normalizes SIP protocols, manages routing policies, and prevents unauthorized access—essential for enterprises and service providers managing mission-critical communications infrastructure.
How many concurrent sessions can the SBC 5400 handle?
The Ribbon SBC 5400 dual chassis configuration supports 10,000 sessions RTU (Ready-To-Use), making it suitable for large enterprise deployments and carrier-grade service provider environments requiring high-capacity session management.
Does the SBC 5400 support IPv6 migration?
Yes, the SBC 5400 includes IPv4-IPv6 interworking capabilities, enabling seamless protocol translation and coexistence during network transitions. This allows enterprises to migrate to IPv6 infrastructure without disrupting existing IPv4-based communications.
What redundancy options does the dual chassis provide?
The dual 5400-2GB chassis configuration provides high availability and redundancy for mission-critical deployments. This architecture ensures continuous service availability and failover protection for enterprise communications infrastructure.
