I found out something I did not know at the Aware website.
Aware’s Fast Retrain Technology Enables More Robust DSL Services
Aware’s Fast Retrain Technology Enables More Robust and Versatile DSL Services BEDFORD, Mass., January 19, 2000 — Aware, Inc. (NASDAQ: AWRE), a worldwide leader in DSL (digital subscriber line) technology for high-speed Internet access over existing telephone networks, today announced that its market-leading fast retrain technology is a key feature in the standards-based splitterless DSL that is gaining wide acceptance throughout the telecommunications industry. Fast retrain has a number of benefits that will allow service providers to offer improved DSL services.
When DSL service is offered without fast retrain, one approach to deployment is to install a voice-data splitter at the point where the phone line enters the home, and string a new phone line from the voice-data splitter to the DSL modem in the home. While this "splittered" approach works, it has certain limitations. Fast retrain technology, which has been standardized by the ITU standards body, provides a more robust and versatile ADSL service. Benefits of fast retrain include:
The ability for complete splitterless operation, which would eliminate the need for the voice-data splitter and the new phone line to the DSL modem.
The ability for complete microfilterless operation, which would eliminate or at worst limit the use of microfilters to only those phones whose voice quality is impaired by the DSL signal.
The ability to use any phone jack in the home as a high speed DSL outlet; not just the one jack provisioned by the separate phone line from the voice-data splitter.
The robustness of the in-home network is maintained as new devices, such as phones or answering machines, are installed after initial installation is complete.
Improved performance in changing noise and crosstalk environments.
Quicker connection times when turning DSL modems on.
Faster transitions from low power modes and sleep modes.
Fast Retrain is applicable to full rate splitterless DSL. I always though it was solely G.Lite.
