Where Networks Interconnect?SBC for Inter-Provider Networking

SP- SP Interconnect:

Eliminatesback-to-back media gateways

Improves media quality

SBC provides admission control,

security, billing, etc.

Can use the same peering routerfor voice, video and data

So, What Is an SBC?

SBC is a tool kit of functions

Depending on the application and deployment scenario, adifferent set of functions can be turned on/off
