GQ-3670

Multi functional Edge QAM Modulator

Product Overview

GOSPELL’s GQ-3670 is a full IP Based Multi functional Edge QAM modulator, which can receive multiple transport streams from an IP network, and then multiplexing, scrambling as well as insert local information to the transport stream and finally output several adjacent QAM channels by RF interface after QAM modulation. Also, It supports up to 256QAM for maximized channel capacity and utilization.

GQ-3670 supports web browser and SNMP management for local and remote monitoring and controlling that can greatly reduce management time and operating expense (OPEX) of operators. It also supports flexible licensing management functions enabling scrambling functions and expand the numbers of QAM channels, Due to its flexibility and versatility, GQ-3670 can be widely applied to DTV head-end system that are located in core-to-edge TS processing and modulation.

Main Features

Supports TS re-multiplexing, scrambling and QAM modulation in 1RU Supports up to four DVB SimulCrypt CAS and DVB-CSA scrambling 3Mbps EMM bandwidth, up to 256 programs scrambled ITU-T J.83 Annex A/B/C compliant, 6MHz or 8MHz bandwidth Transport stream input via Gigabit Ethernet Supports RTP/UDP/ARP/ICMP/IGMP protocols Supports unicast and multicast (IGMP2.0/ 3.0) Supports PSI/ SI auto-generation or manual uploading during re-multiplexing Supports PID filtering, mapping, and pass-through, PCR auto-correction Output frequency range: 30 MHz to 860 MHz Dual RF output ports with up to 16/32 QAM channels output with 4/16-adjecent-frequency Outstanding out-of-band rejection, in-band EPL balance capability Supports Web/SNMP-based management and Multi-language GUI Supports device configuration import/export and online remote update
