International Communications Group’s (ICG’s) NxtLink ICS-400, has successfully completed the “Iridium Compatible Equipment Certification” (ICE) testing, conducted by Iridium Satellite LLC, and is approved for operation on the Iridium constellation and network. The ICS-400, which combines four Iridium transceivers (LBTs) with an internal cabin telecommunications unit (CTU), offers global voice service coupled with telephone services similar to those found in contemporary office Private Access Branch Exchange (PABX) systems. The NxtLink ICS-400 permits connections of conventional telephony devices, other sat-com systems or legacy CTU systems through either standard 2-Wire “Tip and Ring” circuits, 4-Wire audio connections or via CEPT-E1 digital circuits. Standard CTU features include intercom calling, call transfer, conferencing, follow-on dialing and voice prompts. Designed into a 4 Multi-point Control Unit (MCU) Line Replaceable Unit (LRU), the device can be installed on any size of aircraft as the sole communications facility or as an additional/restorative communications system.

The system architecture permits installation on any size airframe or aircraft model, providing flexible connectivity options and solutions for all communications requirements. The NxtLink 400 also provides ARINC 429 connections and a dedicated Short Burst Data (SBD) modem for ACARS services. The device is simple to operate offering standard dialing conventions and PABX operations with familiar call progress tones. It is the ideal solution for aircraft requiring up to 10 telephony connections and seamless global communications services without the inconveniences of hand-offs or no-service areas.
