AVT MAGIC SDC
Redundancy Switch & Converter
The MAGIC SDC enables trouble-free switching of a redundant DAB multiplexer system. To achieve this, continuous time information must be transmitted to a downstream DAB transmitter. Jumps, for example in the time stamp, or even missing time stamps cause a considerable loss of the transmission, since the transmitter would have to synchronize completely again.
With the MAGIC SDC, the output signal of each DAB multiplexer is permanently monitored. If an error is detected in a multiplex, the system automatically switches to the redundant input. The timestamp can be regenerated in the output signal of the switch, so that a continuous timestamp is guaranteed at the transmitter. The switching criteria as well as the switching behaviour (monostable, bistable) can be freely defined by the user.
The system can be used as a classic ETI switch for E1 G. 703/G. 704 lines, or optionally as an EDI switch for IP networks.
If the EDI option is available, the system also enables conversion from EDI to ETI and vice versa, so that DAB multiplexers that no longer support a native ETI can still be integrated into the existing ETI infrastructure.
The system is configured via the PC software included in the scope of delivery and displays the status of the ETI/EDI input data streams and all system parameters in a very clear manner. The software can also be used to manually switch the input for e.g. service purposes. All events are stored in the device in a log file, which can be retrieved via the PC software or alternatively stored in a network folder.
MAGIC SDC supports SNMP v1/v2c protocol for connection to up to four independent network management systems.
The two or four available LAN interfaces are freely programmable in terms of configuration, monitoring, SNMP and EDI input/output.
