When you configure the parameter for the part number, the HSD-440 Mark 2 Terminal
calculates a CRC value for the overall ORT. The HSD-440 Mark 2 Terminal uses the
CRC value to indicate when the ORT has changed.
To configure the secure ORT part number or the user ORT part number:
1. In the list of ORT parameters, type the number next to the SECURE ORT P/N
parameter, or the USER ORT P/N parameter, and then press ENTER.
2. At the SECURE ORT P/N or the USER ORT P/N prompt, type in the part number,
and then press ENTER.
You can type up to 20 characters. The default is blank.
C. Configuring Cockpit Communication Parameters
(1) Configuring the Call Signaling Mode
The HSD-440 Mark 2 Terminal can announce an incoming call in the aircraft cabin
with a chime and light of ARINC

discretes. The call signaling parameter is in the secure ORT.
To configure the call signaling mode:
1. In the list of ORT parameters, type the number next to the COCKPIT CALL
SIGNALING MODE parameter, and then press ENTER.

type 1, and then press ENTER.
The default is CHIME/LIGHT.
(2) Configuring Outgoing Call Signaling
The HSD-440 Mark 2 Terminal can signal an outgoing call with a chime and a flashing
light. The outgoing call signaling parameter enables and disables these signals. This
parameter is in the secure ORT.
To configure outgoing call signaling:
1. In the list of ORT parameters, type the number next to the COCKPIT OUTGOING
CALL SIGNALING parameter, and then press ENTER.
2. To announce outgoing air to ground calls with a chime and light, type 1, or to
disable the chime and light, type 0, and then press ENTER.
The default is DISABLED.
(3) Configuring Ground Public Routing
The HSD-440 Mark 2 Terminal can route public calls from the ground to the cockpit,
to the CEPT-E1 interface, or not route the call (disallowed). The ground public routing
preference parameter is in the secure ORT.
