[SatNews] International Communications Group’s (ICG’s) NxtLink ICS-400 has successfully completed the Iridium Compatible Equipment Certification (ICE) testing, conducted by Iridium Communications Inc., and is approved for operation on the Iridium constellation and network.

The ICS-400, which combines four Iridium channels with an internal cabin telecommunications unit (CTU), offers global voice service coupled with telephone services similar to those found in contemporary office PABX systems. The NxtLink ICS-400 can be integrated with conventional telephony devices, other satcom systems or legacy CTU systems through standard 2- Wire “Tip and Ring” circuits, 4-Wire audio connections or CEPT-E1 digital circuits. Standard CTU features include intercom calling, call transfer, conferencing, follow-on dialing and voice prompts. Designed into a 4 MCU Line Replaceable Unit (LRU), the ICS-400 can be installed on any size 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 ICS-400 also provides ARINC 429 connections and a dedicated Short Burst Data (SBD) transceiver to support ACARS messaging. 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.
