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 transi-
tioning 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.
• DSL Actual Rate: The actual rate at which the DSL link is running (minus DSL overhead).
• DSL Line Condition: Good or Poor.
