High-bit-rate digital subscriber line (HDSL) is a telecommunications protocol standardized in 1994. [1] It was the first digital subscriber line (DSL) technology to use a higher frequency spectrum over copper, twisted pair cables.

2023年11月11日 · HDSL, or High-bit-rate Digital Subscriber Line, is a modulation technology similar to Asymmetric Digital Subscriber Line (ADSL) that uses a group of existing copper twisted-pair subscriber telephone lines to transmit data at T1 or E1 speeds.

2023年4月13日 · High-bit-rate Digital Subscriber Line (HDSL) is a digital subscriber line (DSL) technology that provides high-speed data transmission over a single pair of copper wires.

High-bit-rate Digital Subscriber Line (HDSL) technology is a transparent replacement for a T-1 repeatered line in the distribution plant. It allows DS-1 signals to be transported over distances of up to l 2,000 feet on copper cable without line repeaters.

High-bit-rate digital subscriber line 2 (HDSL2) is a standard developed by the American National Standards Institute (ANSI) Committee T1E1.4 and published in 2000 as ANSI T1.418-2000. [1][2][3] Like its predecessor HDSL, HDSL2 provides a symmetric data rate of 1,544 kbit/s in both the upstream and downstream directions at a noise margin of 5-6 d...

High-bit-rate Digital Subscriber Line (HDSL) technology is a transparent replacement for a T-1 repeatered line. It allows DS-1 signals to be transported over distances of up to 12,000 feet (3700 meters) on unconditioned copper cable, which are cables without line repeaters.

HDSL (High-Bit-Rate DSL) Standardized in 1994, HDSL uses two pairs of 24 AWG copper wires to provide symmetric E1/T1 data rates to distances up to 3657 meters. Its successors are HDSL2 and HDSL4, the latter using four pairs of wire instead of two.

HDSL is applied for wideband digital transmission within corporate sites and between telephone companies and customers. The main characteristic of HDSL is that it is symmetrical; i.e., an equal amount of bandwidth is available in both directions.

hdsl. High-bit-rate digital subscriber lines provide Tl service in both directions for applications that require communications symmetry, such as voice, corporate intranets, and high-volume e-mail. Typical use is between corporate sites. 1 Mbps up- and downstream; range 2–3.4 miles.

2024年10月7日 · HDSL (High-bit-rate Digital Subscriber Line) is a symmetric DSL technology developed in the early 1990s to provide high-speed data transmission over copper telephone lines. The key characteristic of HDSL is its symmetric bandwidth, meaning it delivers equal speeds for both uploads and downloads.
