IEEE 1588 PTP (precision time protocol) is used to synchronise all the nodes within a network. To achieve this one of the nodes must become the master clock and distribute time packets to the others. The AVN-GMC is designed to perform this role simply and accurately, acting as a GPS receiver and enabling sub micro second synchronisation between all nodes.

In normal operation, the unit has PTPv2 time stamping resolution to 8nsec. The AVN-GMC combines a GPS receiver, a PLL (phase lock loop) and a specialist on-board clock device to create the precise, low jitter clock signals required to drive the physical transceiver's time stamping circuitry, also providing holdover if the GPS signal is lost.

The DHY-04HD is an HD Voice & GSM hybrid for handling high quality voice calls, ideal for studios in remote locations, for OB vans and trucks on the move, and in emergency situations where a telephone landline can't be guaranteed. Using a 3G or GSM cellular network, it can receive and make high quality broadcast calls of 7kHz bandwidth, converting the 3G or GSM call to the 4 wire audio signal to and from a connected mixing console. The module used in the DHY-04HD is quad-band GSM and 5 band UMTS/HSPA+, so it can take and make calls on any 2G GSM, or 3G network.
