DAB+ operation in expanded networks that use EDI and ETI multiplexers as sources can prove challenging. Implementing legacy ETI and EDI transmitters in parallel as well as operating DAB in already existing infrastructures not intended for DAB (e.g. DVB-S/S2 or ASI) may also cause obstacles. 2wcom says that its new DAB-4c converter addresses these issues and offers several features that are designed to help users easily navigate switchover phase.
The DAB-4c converter allows operators to receive data signals from legacy ETI and EDI multiplexers simultaneously to converting the signals to the EDI/ETI transmitters in the field. As a high-density solution, the device offers four ETI outputs and four ETI bidirectional interfaces (I/O) to increase the number of ETI outputs if required.
Moreover, the unit is equipped with two Ethernet I/O data interfaces and features an optional satellite tuner for the integration of already existing satellite distribution systems and coverage optimization in regions still lacking broadband IP.
For the synchronization of all sites, the DAB-4c uses PTPv2 or an external 10 MHz signal. In the case of failure, an internal recovery from the EDI stream by jitter removal ensures ongoing synchronized transmission.
For monitoring purposes, the device measures the main DAB+ parameters and provides realtime statistics. On air monitoring at transmitter sites is also possible by means of an optional DAB tuner.
