The Cisco® Unified Border Element (SP Edition) is a high-scale, carrier-grade Session Border Controller (SBC), which is integrated into Cisco routing platforms and can use a huge number of router functions to provide a very feature-rich and intelligent SBC application. In Cisco earlier known as Session Border Controller, Cisco Unified Border Element (SP Edition) provides a network-to-network demarcation interface for signaling interworking, media interworking, address and port translations, billing, security, quality of service, call admission control, and bandwidth management.
This paper provides an overview of the Cisco Unified Border Element (SP Edition) implementation in a Unified Session Border Controller (SBC) deployment model on the Cisco ASR 1000 Series Aggregation Services Routers. It also briefly explains what the Session Border Controller is, its different deployment models, and where the SBC’s different functionalities can be used to achieve different solution objectives. This paper assumes that the reader has basic understanding of voice technologies such as Session Initiation Protocol (SIP) and H323 protocols and the need for an SBC.
