• Circuit Switching: A networking technology that provides a temporary, but dedicated, connection between two stations no matter how many switching devices the data is routed through.
• Packet Switching: A digital network technology that breaks up a message into smaller chunks (packets) for transmission.
• Leased Line: A private communications channel leased from a common carrier.
• Time-Division Multiplexing: A technology that transmits multiple signals simultaneously over a single transmission path.
• T-carrier System: The generic designator for several digitally multiplexed signal carrier systems.
• DS0: A single 64 Kbps channel, which is the building block of a T1 transmission line.
• DS1: Digital Signal. A classification of digital circuits. The DS refers to the rate and format of the signal.
