A graphical method and system of tracking projects managed in accordance with Theory of Constraints project management techniques. A graph of project and feeding chain buffer consumption is constructed for at a glance project status review by management. Alternate buffer consumption models may be utilized.

Method and system for theory of constraints buffer graphing, tracking and management

The integrity of a signal path through a transmission system (12), which processes successive blocks (14) of data during a given time frame, verified by establishing the parity of a selected one of the blocks as it enters and as it leaves the system. A lack of equality between the parities is indicative of a lack of path integrity.

Disclosed is a communications network for peripherals in a digital loop carrier transmission system. A broadcast STAR network is employed so that all peripherals receive any message which is broadcast by any of the peripherals. No peripheral broadcasts without clearance from the active communications hub. Two hubs can be provided to alternatively act as the active hub. Each peripheral includes a controller which transmits a request to send signal, multiplexes the request to send signal with an outgoing message, receives clear to send signals, and demultiplexes the clear to send signals from an incoming message.
