It acts like a fixed pipeline that carries data from one fixed point to another and makes services like frame-relay possible. Also called leased channel, leased circuit, or private line.

2. Telephone line connection with only two end points. A PTP circuit is a direct channel between two specific locations, dedicated to one customer and billed usually at a fixed monthly cost irrespective of the line traffic. Also called point to point circuit, or private circuit.
