	High-bit-rate Digital Subscriber Line (HDSL)
		HDSL uses two-pair copper cable for full-duplex transmission, using echo cancellation with each pair carrying 784 kb/s.
		HDSL is particularly attractive since approximately 85% of the local loops nationwide are within the customer serving area (CSA) guidelines of up to 12,000 feet and represent well-entrenched copper infrastructure.
		HDSL is an important breakthrough technology that is currently in the eatIy, stages of it, evolution, but it is not the ultimate solution for all high-capacity applications.

	DSL Service - HDSL (High Bit-Rate DSL)
		HDSL (High-Bit-Rate Digital Subscriber Line) is the earliest variation of DSL, and is commonly used as a substitute for T1 (Traditional T1) in the United States and E1 in Europe.
		HDSL has the capability to transmit data at the same speed in both directions.
		HDSL is used between the telephone company and a customer.

	Define HDSL - High-Bit-Rate Digital Subscriber Line
		HDSL is a way to provide full-duplex symmetric data communication at rates up to 1.5 Mbps (2.048 Mbps in Europe) over moderate distances via conventional telephone twisted-pair wires.
		HDSL can carry as much on a single wire of twisted-pair cable as can be carried on a T1 line (up to 1.544 Mbps) in North America or an E1 line (up to 2.048 Mbps) in Europe over a somewhat longer range and is considered an alternative to a T1 or E1 connection.
		HDSL is becoming popular as a way to provide full-duplex symmetric data communication at rates up to 1.544 Mb/s (2.048 Mb/s in Europe) over moderate distances via conventional telephone twisted-pair wires.
