ICG NxtLink ICS-120B

The ICG NxtLink Series ICS-120B Iridium communications system incorporates a single-channel Iridium transceiver with CTU features, providing a standalone comprehensive communications system. The ICS-120B permits connections of conventional telephony devices or legacy CTU systems via standard 2-Wire “Tip and Ring” circuits or 4-Wire audio connections.

This CTU features include intercom calling, call transfer, conferencing and follow-on dialing. 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 no more than six telephony connections and seamless global communications services without the inconveniences of hand-offs or no service areas. The ICS-120B has a connection for an optional external SIM card reader making them a true LRU.
