Frequently Asked Questions
What is a session border controller and why do I need one?
A session border controller (SBC) like the Ribbon SBC 5400 manages and secures voice and video communications at network borders. It provides essential functions including SIP normalization, network security, policy enforcement, and protocol interworking—critical for CSPs and enterprises handling multimedia traffic at scale.
What does the 1,000 sessions RTU licensing mean?
The 1,000 sessions RTU (Right-to-Use) indicates the concurrent session capacity included with this SKU. This dual 2GB chassis bundle supports up to 1,000 simultaneous sessions, making it suitable for mid-to-large enterprise deployments and service provider networks.
How does the dual 2GB chassis provide high availability?
The dual chassis configuration enables redundancy and automatic failover protection. If one 2GB chassis experiences issues, the system seamlessly switches to the backup, ensuring continuous service availability—essential for mission-critical communications infrastructure.
Does the SBC 5400 support IPv6 and legacy IPv4 networks?
Yes. The Ribbon SBC 5400 features IPv4-IPv6 interworking capabilities, allowing it to bridge legacy IPv4 networks with modern IPv6 deployments. This dual-stack support enables smooth network transitions without service disruption.
