In the HF system, the RMPs are used for HF1 and HF2 frequency control. The HFDR 1 transceiver is connected to the Air Traffic Service Unit The HFDR transceivers have 2 serial input ports: (ATSU) for direct exchange of data between the A/C and ground systems - serial input port A, like A/C report or weather report. - serial input port B. The HFDR transceivers are also connected to the Data Loading Routing In normal conditions, both transceivers are tuned through port A from Box (DLRB), which is used to load the HFDR software. any RMP. The secondary port is dedicated to RMP2 when RMP1 and RMP3 have failed.

The AMU acts as an interface between the users and the HF systems for transmission and reception of audio signals. The Push-to-Talk (PTT) key line is a ground signal sent to the transceiver through the AMU. The SELective CALling (SELCAL) system gives visual and aural indications to the flight crew, concerning calls received through the HF system. NOTE: The SELCAL function is integrated in the AMU. The ACPs are used for HF transmission or reception selection mode and control of the received audio signal levels through the AMU. A BITE is integrated in the HF transceiver, for maintenance purposes. The BITE maintains 2-way communications with the Central Maintenance G7508471 - G7UT0TU - FM23D2000000002 Computers (CMCs) through ARINC 429 buses. The BITE is used to detect and identify internal and external transceiver failures, to store maintenance data in a memory, to inform the external maintenance monitor, the CMC, and to execute tests. Through the Landing Gear Control and Interface Unit (LGCIU) 1/2 a discrete ground signal is sent to the HF transceivers, when the A/C is in flight with L/G down or not.

DATA TRANSMISSION Each VDR transceiver can operate in VOICE mode or DATA mode. In position 3 only, the VDR is active in DATA mode. The ATSU sends data packages to the VDR 3 transceiver for modulation. The obtained VHF signal is then sent to the antenna for emission. Upon receipt of VHF signals, the transceiver, when tuned on the selected frequency, transforms the signal into digital format, and transmits the data to the ATSU.

PA signals are broadcast from the cockpit or cabin crew stations through all the cabin loudspeakers. To make PA announcements, the cabin crew uses the cabin handsets. The quickest way to initiate a PA from the cockpit is to use the cockpit handset, directly connected to the Directors. The cockpit crew can also send a PA using the PA key on the ACP and the cockpit acoustic devices. A Pre-Recorded Announcements and boarding Music (PRAM) sends pre-recorded announcements and boarding music to the Directors to be broadcast through the PA system. There are two types of PRAM, which have identical functions. It can be a flash memory type plugged into the FAP or an audio tape reproducer installed in the avionics bay. The PRAM, whatever its type, is controlled from the FAP. Note that PA announcements are also broadcast to the passenger headsets via the IFES. In the event of a PA, the cabin crew is informed by messages on the AIPs and the cockpit crew by a message on the EWD.

The cabin crew can initiate a call to another cabin crew station or to the cockpit by dialing on the handset. To call the cabin crew from the cockpit, the overhead CALLS panel is used. To speak to a cabin crew member from the cockpit, the CABin transmission key and the CABin reception key on the ACP are adjusted accordingly. In the cabin, the cabin crew is aware of a call by visual indication on the AIPs and ACPs, associated to the called station. Hi-lo chimes are also broadcast in the assigned zones through the cabin loudspeakers.

They are fully identical and have the same outputs and inputs. They provide to each other their operational status through a discrete signal and data and failure information through ARINC 429 buses.In normal operation, Director 1 is operative and Director 2 is in hot stand-by. This means that Director 2 receives and computes the same data as Director 1 but its outputs are disabled. The Directors are linked with the Flight Attendant Panel (FAP) through two wire types: - by Ethernet for data exchange, - by discrete for each hard key. System reconfiguration for the installation of options, cabin reconfiguration or CIDS expansion is limited to software database changes. These database are the On Board Replaceable Module (OBRM) and the Cabin Assignment Module (CAM). They are downloaded from the FAP.. The CIDS is also designed to detect internal and external faults. The CIDS is a type 1 system. It is connected via the Directors to the Central Maintenance System (CMS) for maintenance purposes (BITE and G7508471 - G7UT0TU - FM23D7000000003 tests).
