Hi to all here.
In the following post, you will learn about XDSL technologies.
xDSL: Principles and Applications
xDSL Technology OverView
DSL Standard
· Currently, there are many organizations working on DSL standards. The most important organizations are the American National Standards Institute (ANSI), the European Telecommunications Standards Institute (ETSI), and the International Telecommunication Union (ITU). In ANSI, the T1E1 committee is responsible for network interfaces, power, and protection, and the T1E1.4 working group is responsible for the standardization of DSL access. In ETSI, the TM6 workgroup is responsible for DSL access standards.
· ANSI and ETSI are regional standard organizations, while ITU is a global standard organization. Currently, the ITU defines the following DSL standards:
§ G.991.1 first-generation HDSL standard
§ G.991.2 second-generation HDSL standard (HDSL2 or SDSL)
§ G.992.1 full-rate ADSL standard (G.dmt)
§ G.992.2 ADSL standard without splitter (G.lite)
§ G.993 is reserved future VDSL standard
§ G.994.1 DSL handshake process (G.hs)
§ G.995.1 DSL overview
§ G.996.1 DSL test process (G.test)
§ G.997.1 DSL physical layer maintenance tool (G.oam)
ADSL Standard
§ G.991.1 first-generation HDSL standard
§ G.991.2 second-generation HDSL standard (HDSL2 or SDSL)
§ G.992.1 full-rate ADSL standard (G.dmt)
§ G.992.2 ADSL standard without splitter (G.lite)
§ G.993 is reserved future VDSL standard.994.1 DSL handshake process (G.hs)
§ G.995.1 DSL overview.996.1 DSL test process (G.test)
§ G.997.1 DSL physical layer maintenance tool (G.oam)
ADSL2 Standard
VDSL2 Standard
· In ITU-T, the standard numbering is G.993.2, which is a formal standard released by ITU-T in May 2005. To launch the VDSL2 standard, ITU formulated the RFC3728 MIB standard in October 2004.
This is a bit preamble for the xDSL technologies. Wait for the next post, remember: click on ♥, share and comment. Thanks.
