• DSL Sync State: Out of Sync, Acquiring Sync, In Sync, or Losing Sync.

NOTE: DSL Link State vs. DSL Sync State—The DSL link state describes whether
the DSL is training (in progress), linked (success), deactivated (we don’t have an
option to deactivate the modem, so the user should not see this), or idle.

The DSL sync state describes whether no sync words have been found (out of sync),
there are no sync word errors (in sync), or whether we are transitioning from out of
sync to in sync (acquiring sync) or vice versa (losing sync). Typically, when the link is
training, the sync state goes from out of sync to acquiring sync to in sync.

overhead).
