G.shdsl (G.991.2)

Single-pair high-speed digital subscriber line (SHDSL) transceivers designed primarily for duplex operation over mixed gauge two-wire twisted metallic pairs. Optional four-wire operation is supported for extended reach applications. Optional signal regenerators for both single-pair and two-pair operation. SHDSL transceivers are capable of supporting selected symmetric user data rates in the range of 192 kbit/s to 2 312 kbit/s using a Trellis Coded Pulse Amplitude Modulation (TC-PAM) line code. SHDSL transceivers do not support the use of analogue splitting technology for coexistence with either POTS or ISDN. Regional requirements are supported.
