Cisco Certified ExpertTraining Mode Options
DSLAMs sometimes have options for specifying the training procedure. For example, in the Cisco systems, you might encounter the options standard train and quick train, or standard train and fast train. Standard train relates to a training procedure specified in ANSI standards document T1.413, which is considered the standards reference for DMT ADSL. (Any manufacturer offering the option standard train should ensure that the option is T1.413 compliant.) Quick train, fast train, and so on can be more proprietary and perform best when used with the same manufacturer's modems (and usually the same DSL chipset) on both ends of the telephone line. Further, quick train might not always result in a faster train-up by the modems.
