Telematics Communication Interface Control Module

The ERA Glonass Telecommunications Platform (TCP) system communicates with various infotainment components via Ethernet. The ERA Glonass system uses Global System for Mobile Communication (GSM) to communicate data and voice signals over the national cellular network. The Telematics Communication Interface Control Module (TCICM) supports entertainment WiFi hotspots by providing a connection to the cellular network for internet access. The module is capable of up to 4G LTE speeds and houses 2 technology systems, one to process Global Positioning System (GPS/Glonass) data, and another for cellular information.

The telematics communication interface control module has two antenna inputs, a cellular signal and a GPS/Glonass signal. The ERA Glonass system uses the Global Navigation Satellite System (GNSS), which is a combination of United States Global Positioning System (GPS) signals and Russian Glonass satellite system. GPS/Glonass signals are used to provide location on demand.

Dedicated circuits are used to connect the telematics communication interface control module to a microphone, button assembly, radio and backup speaker. When equipped, the TCICM may contain a Back-Up Battery (BUB) which is internal to the control module and replaceable through an access cover. The telematics communication interface control module communicates with the rest of the vehicle over the serial data bus and Ethernet. Power is provided by a dedicated, fused B+ circuit. Ground is provided through the vehicle wiring harness attached to the module. The power mode state is determined by the telematics communication interface control module through serial data messaging. The telematics communication interface control module will power down 3 seconds after the button assembly LED shuts off.
