International Communications Group Provides Customer Ease of SIM Card Replacement with Enhancements to NxtLink Product Series


Newport News, VA (October 1, 2009)—International Communications Group (ICG) announced today that it has enhanced its NxtLink product series with an upgrade to now incorporate the Configuration Identity Module (CIM). The CIM is an external SIM card reader that provides installation of up to 2 SIM cards. Previously, the external SIM reader was only compatible with the NxtLink 120A and 220A Iridium transceivers, but now supports the NxtLink ICS-100 and ICS-200 product line, as well.

“The CIM will allow operators to maintain SIM card information ( MSISDN, & Telephone Number) on the aircraft regardless of the NxtLink transceiver installed,” said ICG Vice President of Engineering, Darrell Andregg. “By maintaining the Iridium SIM card information on the aircraft, this will allow quick line changes for system upgrades or troubleshooting. Because the external SIM card reader is not physically located inside the transceiver unit, operators can switch service providers without removing the transceiver. They will be able to do so by simply inserting new SIM cards in the CIM module.”

Previously, the aircraft telephone number was associated with the SIM internal to the NxtLink transceiver and not the airplane, making SIM or unit replacement inconvenient, requiring reassignment of SIMs and transferring of telephone numbers within the Iridium network. The CIM permantently links the telephone number directly to the to the aircraft tail number. The CIM also reduces aircraft down time by allowing the technician to switch out SIM cards or LRUs quickly and efficiently without a requirement to open the device and obviate the ensuing “return to service” process.

The NxtLink ICS-200 incorporates two channels of Iridium that can support voice, fax and ACARS all in one unit. Its dual Iridium transceivers with an internal CTU provide a standalone, comprehensive communications system that can operate over a single coax and Iridium antenna. It works with either standard 2-Wire “Tip and Ring” circuits or 4-Wire audio connections to provide intercom calling, call transfer, conferencing and follow on dialing. The ICS-200 is simple to operate, with standard dialing conventions, PABX operations and familiar call progress tones. It is the ideal solution for aircraft requiring no more than six telephone connections and seamless global communications services without the inconveniences of hand-offs or no service areas.

“This CIM unit reduces the complexity of maintaining aircraft and simplifies the process of changing service providers or replacing or upgrading hardware,” Andregg concluded.
