DSR-4400MD Satellite Multiplex Decrypter


Product Code: MOT-DSR-4400MD


The Motorola DSR-4400MD is a powerful digital headend product, capable of simultaneous decryption of up to 24 services. Whether your application is to feed a 256 QAM channel or a 64 QAM channel, the DSR-4400MD is the answer. With the DSR-4400MD, you can output a full MPEG-2 multiplex at an information rate of 38.8 Mbps or 26.97 Mbps, depending on your needs.

The Motorola DSR-4400MD comes equipped with industry standard interfaces that enable seamless connection to DigiCipher II IRT-1000/2000, MPS Remultiplexer and other head-end equipment for cable encryption and cable modulation.

The ASI and DHEI inputs provide additional flexibility for the Motorola DSR-4400MD by allowing loop-through decryption capabilities when more than 24 services of decryption are required. They also provide a convenient mechanism for monitoring and troubleshooting the signal as it passes through the cable headend.

The full range of DigiCipher II system symbol and code rates is supported, including the higher combined symbol rate of 29.27 Msps, rate 3/4 to enable 40.46 Mbps information rate transmission. With the lower SCPC rates, the DSR-4400MD becomes a flexible product that supports partial transponder utilization. Packaged in a 1RU chassis, the DSR-4400MD offers local monitoring of a single service and the ability to step through the authorization and encryption state of each service. In the event of a transport stream fault, or loss of authorization for any of the provided services, the DSR-4400MD will trigger an alarm indication for the user.
