Single Pair High Speed Digital Subscriber Line
Generally a different name for SDSL.
Symmetric High Bit-rate Digital Subscriber Line. SHDSL is one of the xDSL technologies, which makes it possible to transmit 2.3 Mbit/s in both directions on an ordinary telephone connection, but this cannot be used simultaneously for transmitting telephone calls. Other SHDSL solutions can offer higher speeds by using several connections.
Symmetric High-bit-rate Digital Subscriber Line. A DSL variant that achieves upstream and downstream data rates up to 2.3 Mbps over a pair of copper wires or 4.6 Mbps over two pairs of copper wires. SHDSL is a single-pair version of HDSL. SHDSL conforms to ITU-T G.991.2 (G.shdsl) Recommendation. Also see DSL. Compare with HDSL.
ITU G.991.2 standardized method to transport data symmetrically at data rates of 192 kbps to 2.3 Mbps over 2-wire, or 384 kbps to 4.6 Mbps over 4-wire.
SHDSL is an ultra high speed DSL technology with the same download and upload speeds. SHDSL is designed for use with databases, VPNs (Virtual Private Networks), and in-house servers requiring remote access.
Symmetric high-speed digital subscriber line. A standardized multirate symmetric DSL that transports rate-adaptive symmetrical data across a single copper pair at data rates from 192 Kbps to 2.3 Mbps, or from 384 Kbps to 4.6 Mbps over two pairs, covering applications served by HDSL, SDSL, T1, E1, and services beyond E1. SHDSL conforms to the following recommendations: ITU G.991.2 G.SHDSL, ETSI TS 101-524 SDSL, and the ANSI T1E1.4/2001-174 G.SHDSL. See also G.SHDSL.
