Digital multimedia system Arris D5 Universal Edge-QAM

1

 ARRIS D5 Universal Edge-QAM (UEQ) is a solution for processing of SPTS and MPTS MPEG-streams received from IP-network, establishment of multiplex channels, and their transmission as QAM-modulated signal in HFC network.

This platform allows simultaneous injection of up to 3000 MPEG streams – via four GigabitEthernet interfaces located on network access module. Received video streams can be multiplexed and sent to any output RF-interface. Such traditional MPEG-processing functions as PSI/SI management, PID reassignment, recovery of PCR synchronization, and scrambling have been implemented as well. One chassis (2U form-factor) can comprise up to six modulator boards, each of which can form up to 24 QAM Channels (8 MHz). Due to such high density, number of QAM can be increased up to 144 – by installing the additional modulator cards.

Arris Edge-QAM D5 supports the transfer of direct DOCSIS channels within M-CMTS system, as well as the cut-through data transfer. Interaction with M-CMTS core is realized via DEPI interface. CableLabs DOCSIS Timing Interface (DTI) specification is fully supported as well. D5 platform enables simultaneous transmission of both direct DOCSIS channels and digital cable TV signals (in the same chassis).
