high-speed access to SDH networks

Restrictions

two pairs are used for full stream transmission

4.1.5 Multispeed DSL (MDSL) technology

The term SDSL was used for several years on the market. It was referred to all solutions meant for the synchronous digital stream transmission over one pair. This technology supports the possibility of line speed regulation over long-haul distances. The technology is implemented in MDSL and MSDSL, the latter one having a different line code. The MDSL technology uses 2B1Q line code. The transmission rate varies from 144 to 2320 Kbit/s. Regenerators are not used here.
