Restrictions
• the shortest distance of data transfer over one wire compared to other technologies
4.1.6 Multispeed DSL (MSDSL) technology
The MSDSL technology is a further development of the MDSL technology. It allows to run over
longer distances because of using a more progressive line code – CAP. In addition, it is possible
to install a CAP-splitter, which allows using the copper pair for both data transfer and telephoning
connection. The technology supports the installation of a line regenerator. However, the spectral
characteristics of the CAP code interfere with other xDSL systems, running over the neighboring
pairs in the same cable. The ADSL technology is exposed to the greatest influence.
