TOPSPAN MSDSL

Product Overview

TOPSPAN-MSDSL (Multi-rate Symmetric Digital Subscriber Line), is a data & tele communication integration equipment by using Multi-rate DSL technology over one pair of twisted copper wires. It can provide transmission rate from 128 Kb/s to 2.304Mb/s at the distance from 3 to 7km without repeaters, respectively.

TOPSPAN-MSDSL can equip with EIA RS-530/V.35/RS-449 DTE interface for data transmission and G.703 T1/E1 or Fractional T1/E1 to support drop & insert functions. This accordingly makes our MSDSL the best choice on applications such as INTERNET access and leased lines service for the last mile solution.

Because of the state-of-the-art design and techniques, our TOPSPAN-MSDSL is of high reliability and best quality, and also saves time on installation, operation and maintenance in a cost-efficient way.
