When specifying new timer values, remember that all PPL Timers are specified in 10 ms increments. For example, a PPL timer for 4 seconds is specified as 4000 (decimal, 400 x 10 ms = 4 seconds), which is the hexadecimal value of (0x190).

See Programmable Protocol Language.

In PPL, a condition that, when met, drives a state machine (PPL Component) from one state to another, by invoking an associated Primitive. In PPL files, an Event is marked by an arrow and text.

See Pulse Code Modulation.

The point in the Excel platform where a DS0 connects to a network. Also known as a "socket."

A condition that, when met, drives a state machine from one state to another. A condition that drives a Component out of its current state by invoking an associated primitive.

Range of channels provided by T1 or E1 transmission service. A physical span is a group of channels taking up a single physical wire. A logical span is a group of channels taking up less than a single logical wire, or carried over more than one physical wire.

The condition of a component at a given instant. The current "context" of a PPL object, such as Idle, Seizing, Answered. In PPL files, a State is represented by a circle.
