Command Description
S HSSI Port State—When Configuration Mode (below) is Automatic, the Port State is an
informational display. In Automatic mode the HSSI data port is In Service when DTR is
presented by the DTE and it is Out of Service when the DTE fails to assert DTR.
When Configuration Mode (below) is set to Manual, the Port State command becomes a
toggle. If Mode = Manual and Port State = OUT OF SERVICE, then issuing the Port State
command will place the port IN SERVICE, whether or not any DTE is present and whether or
not it is asserting DTR. Conversely, if Configuration Mode = Manual and the Port State = IN
SERVICE, issuing the Port State command will place the port OUT OF SERVICE, stopping all
user data.
