Working with Pipe Signal Termination Point Specifications

You use Pipe Signal Termination Point specifications to define signal structures. A signal structure defines a multiplexing hierarchy where data streams are separated into multiple lower data communication links. For example, a DS1 signal structure can define a 1.536 Mbps data stream as 24 DS0 signals, each supporting 64 Kbps. The signal structure defines the channel hierarchy for a pipe facility that supports time division multiplexing (TDM), such as a T1 or an E1 facility.

You create a hierarchy of Pipe Signal Termination Point specifications to define the signal structure. The highest-level Pipe Signal Termination Point specification in the hierarchy (the parent) represents a trail termination point (TTP). You associate this parent specification to a Capacity Provided specification to define the total bandwidth capacity provided by the signal structure.

The child Pipe Signal Termination Point specifications represent connection termination points (CTP). A signal structure can have multiple levels of child Pipe Signal Termination Point specifications, each representing a further breakdown of the data stream defined by the preceding specification in the hierarchy.

You associate the highest-level Pipe Signal Termination Point specification (the parent) of a signal structure to a Pipe specification to define the channel hierarchy and capacity provided by the pipe facility.
