High-Speed Digital Subscriber Line Commands (HDSL)
The following HDSL commands are used to manage the HDSL link for an HDSL router.
General Information about HDSL

Line activation
Line activation is independent of network settings. During activation, the Link light (on the front panel of
the router) first is yellow and then turns green when the link becomes active.
The router at the CPE end will try auto-speed detection, starting at 384 and then try to detect the next
higher speed (for about 30 seconds per speed). The WAN light should turn yellow, then green, when the
link has activated.
Auto-speed detection can be turned off with the command hdsl speed noauto.
If the line was previously set to Òno auto-speedÓ (noauto), the Link light will be amber instead, when the
line tries to activate.
The ifs command displays the Link as either off or opened when successfully activated. Following is a
sample output.

Auto-speed sequence
Auto-speed starts with the lower speed (384) and then tries to activate for 30 seconds. If no activation
takes place, it attempts the next higher speed. The time intervals between activation may change if the
modems donÕt activate as expected. Following is a correct activation output.
