184 Chapter 8: Using DSL to Access a Central Site

Setting the Training Mode

Two training modes are available—standard and quick. Standard train relates to a training

procedure speciﬁed in ANSI standards document T1.413, which is considered the standards

reference for DMT ADSL. Quick train, also called fast train, uses a vendor-speciﬁc training

sequence that is shorter than the standard training sequence.

To modify the training mode in a DMT proﬁle, use the following command:

dmt training-mode {standard

quick}

In Example 8-5, the command sets the ccnp proﬁle’s training mode to quick.
