<p>An operating system independent distributed self-contained dynamic logic system enables EO functionality in small edge routers or progammable switches and provides the capability for EO switch enhanced functionality that is programmable from a remote location. The dynamic logic system may be implemented across several elements, including a subscriber database called a Service Control Point (SCP), a computer called a Service Management Point (SMP) for controlling and distributing programmable logic to implement EO features, and an Edge Switching Point (ESP) for interacting with a physical device (telephone/data endpoint). The dynamic logic system may be introduced at the "intercept" layer between the physical edge switching point device, typically a telephone interface, and a routing network. The routing network may be a packet switched network, a traditional Class-4 network, or an equivalent. This intercept receives inputs from both the device, and the routing network. The processing of these events, to create an application, is controlled by distributed logic. The distributed logic is managed by the SMP. The logic is activated by an operator, and is distributed for consumption. The logic is completely self-contained, requiring only subscriber data to execute, which is obtained on a call-by-call basis. EO switching functions such as playing tones, gathering digits, and routing calls, may be provided.</p> |
