Binaural Audio Support: Provides high-quality audio with ANR (Active Noise Reduction) and dual headset capability per position.
Up to 60 radio channels and intercom networks can be accessed through the IPCSU when used with a full ATR CCU. Receive and Transmit channels are selected via simple push-button keys. When a channel is selected, its status LED is illuminated and its volume is automatically set to mid-range or to the level set after power-on. Panel LEDs also display the channels selected for transmit and their associated security level. Receive and transmit indicators can be programmed to flash if there is receive or transmit activity on a given channel. The panels can be customized to allow for additional control features. These include crypto switching, modem switching, clear/secure selection, radio relay and others. The panel can also be set up to allow selection of several conference intercom nets, direct access channels to crew positions or dial-up calling. Other typical panel features are ICS Disconnect, Alternate ICS and PTT ICS/radio select.
The CDU is a microprocessor-based control and display unit that gives the crew member access to radio and intercom audio channels. The full-function keyboard allows the user to control transmit and receive functions such as assignment of all communication assets including crypto units, data-link modem switching, radio relay and display of Built-In-Test (BIT) readouts. Complete status of the communication assets for each.
The CCU networks and controls the links between communication assets and crew members. The CCU is a modular, microprocessor controlled, TEMPEST qualified secure unit that is integrated into the communications suite to provide the necessary control and switching of all internal and external, clear and secure voice and data lines by the crew members.
The CCU is available in half and full ATR size depending on system and redundancy requirements. The unit can be interfaced to mission computing via MIL-STD-1553B data buses or optional Ethernet connections. Its modular circuit card assembly design allows the CCU hardware to be tailored to meet multiple platform requirements. Flexible firmware functionality enables a single CCU type to be used on multiple platforms with different configurations and communication plans. It is this flexibility that enables its use from small internal/external communication systems up to full command and control systems. Larger and more complex systems can include crypto and data link assignments, clear/secure radio relay, clear/secure simulcast, unlimited internal conference networks and/or selective dial-up.
The MSU provides interphone channels to remote aircraft locations for maintenance functions or remote crew interphone stations. Each MSU provides a headset connection, adjustable volume control, HOT MIC, and CALL functions. MSUs come in a variety of sizes.
The ACU provides access to radio and intercommunication channels in a small form factor. Up to 30 radio and/or intercom channels can be assigned to the panel pushbuttons.
The Flight Deck Audio Panel (FDAP) provides flight crewmembers access to conference interphone networks, radio channels, guard channels, NAVAIDs, and selective interphone networks. The panel features separate volume controls for the individual channels as well as a master volume control. LEDs above channel selector buttons indicate whether channels have been selected for receive or transmit and also flash when receive or transmit channels have activity. The FDAP supports multiple levels of security and can operate as a stand-alone unit or in conjunction with legacy flight deck audio control panels.
The Audio Switching Unit (ASU) provides the connections between the communications assets and each crew member. The ASU is a modular TEMPEST secure digital unit that is integrated into the communications suite to provide the necessary control and switching of all internal and external, clear and secure voice and data lines. The ASU features multi-level security, non-blocking digital switching using TDM buses. The high speed TDM approach has high capacity and very low, deterministic latency, thus providing high quality of service and high-quality audio. The ASU interfaces with communications assets can include T1/E1 (PSTN), Gigabit Ethernet (wire or fiber optic), analog (four-wire or two-wire), ISDN and VoIP. The modular architecture of the ASU allows for the addition of interface cards for new interface standards as they develop, or addition of new protocols utilizing software changes to existing cards. The ASU can operate as a stand-alone unit or with multiple ASUs. ASUs interface with each other via redundant high speed (OC3) serial data links.
The MSU provides interphone channels to remote aircraft locations for maintenance functions or remote crew interphone stations. Each MSU provides a headset connection, adjustable volume control, HOT MIC, and CALL functions. MSUs come in a variety of sizes.
The Mission Audio Panel (MAP) provides access to internal and external communications channels while supporting multiple levels of security. The MAP is a binaural unit, which gives the user complete control and status of the communications assets. Controls allow the users to select radio and intercom channels for receive and transmit as well as set the volume, stereo balance or spatial location for each channel. The keypad allows one to control selective intercom, VOX, Hot Mic, channel security, recorder playback, and so on. The color LCD display shows the level of security, radio frequency, channel name, along with receive and transmit activity for each channel. The MAP has master volume controls for two users.
The Handset Audio Panel (HAP) provides access to internal communications channels. The HAP connects to a handset with a wall hook to provide the user audio interface. The keyboard allows the user to call other crewmembers on conference or selective intercom channels.
