Transmission and Multiplexing (TM); Access transmission system on metallic access cables; Symmetric single pair high bitrate Digital Subscriber Line (SDSL) (V1.4.1)
This Technical Specification (TS) has been produced by ETSI Technical Committee Transmission and Multiplexing (TM). The present document is partly based on the T1E1 HDSL2 specification. In turn@ the ITU-T Recommendation G.991.2 (G.shdsl) annex B text was largely based on earlier versions of the present document. Efforts have been made to ensure that the ITU G.shdsl and ETSI SDSL work items were kept in line. To facilitate this alignment this revision of the present document was produced as an endorsement of ITU-T Recommendation G.991.2 (2005) with modifications and additions.
