1.0 HDSL Systems
1.1 HTU Applications
The High-Bit-Rate Digital Subscriber Line (HDSL) is a simultaneous full-duplex
transmission scheme which uses twisted-pair wire cables as the physical medium
to transport signals between standard types of network or subscriber
communication interfaces. A complete HDSL system consists of two pieces of
terminal equipment connected by 1, 2, or 3 wire pairs. Each HDSL Terminal Unit
(HTU) translates standard interface signals into HDSL payload for transmission,
and reconstructs the standard interface from received payload. Bellcore standards
define a 1.544 Mbps T1 transport application that uses two HDSL wire pairs
(2T1), each operating at 784 kpbs. ETSI standards define a 2.048 Mbps E1
transport application using either two wire pairs (2E1), each operating at 1168
kpbs, or three wire pairs (3E1), each operating at 784 kpbs.
