标准简介：G.99~DSL Recommendations facilitate transmission of digital data over the copper pair. G.993.1 provides a foundation for transceivers that may support both asymmetric and symmetric operations at much higher data rates when compared to G.991.1 and G.991.2 for symmetric date rates and G.992.1 and G.992.2 for asymmetric data rates. In the Fibre-to-the-exchange (FTTEx) type of deployment, G.993.1 transceivers would provide less loop plant coverage than the G.991.1, G.991.2, G.992.1 and G.992.2 transceivers. The coverage can however be increased using the Fibre-to-the-cabinet (FTTCab) type of deployment. G.993.1 based transceivers would be able to coexist with underlying narrow-band POTS or ISDN services, as is the case with G.992.1 and G.992.2. The Network Operators would also be able to choose to provide VDSL on access lines without any narrow-band services.
