ARPD

ARPD Next-Generation Modular Compact Demodulator

The Advanced RPD (ARPD) offers greater demodulator density in a more compact chassis than its predecessor, the RPD-2000. It offers a larger number of upstream demodulators in a smaller physical package. Performing the same functions as the RPD-2000 while saving rack space, the ARPD allows multiple upstream demodulators to be placed in each upstream path.

This modular 1 RU product supports the inclusion of up to six removable (hot-swappable) ADM-4000 demodulator modules. It increases the bandwidth capacity of each upstream return path, allowing the system to support increased VOD penetration and the introduction of new interactive features such as switched digital video.



Features
Support
  • Offers high-density compact design.
  • 1 RU chassis holds up tosix ADM-4000 Advanced Demodulator Modules* and can be functionally equivalent to three RPD-2000s, saving rack space.
  • Each ADM-4000 module includes two RF ports (input and output) and supports the ability to demodulate up to three different return channels.
  • A fully loaded ARPD chassis containing six ADM-4000 modules supports up to six different upstream paths and the ability to demodulate up to 18 different return channels.
  • The ADM-4000 demodulator modules are front-loading (cables connect in the back) and hot-swappable.
  • Tuner frequency range is from 5 to 65MHz, and the dynamic range is 20 dB (0 dBmV ±10 dB).
  • Receives and demodulates upstream data packets (MAC cells) transmitted by STBs and performs FEC, marking each received cell as perfect, corrected, or uncorrectable.
  • Performs power level measurement on each demodulated MAC cell to support the STB power leveling system.
  • Transmits the demodulated MAC cells containing interactive data and/or polling data to the NC1500 or RADD over UDP/IP/Ethernet.
  • Provides status and alarms using SNMP traps.
