Disconnected The port is administered but the associated digital link does not
respond. An administered port is put in a disconnected state after a
system reboot or circuit pack insertion. This state persists until a
link-reset-pass message is received from firmware on the circuit
pack.
In-Service When switch software receives a link-reset-pass message from the
port, the port is placed in service. If the link-reset-pass message is
missed, and an off-hook message is received while the port is in the
disconnected state, maintenance software will run an ID request test
and put the port into service upon receiving a correct response.
