About D3 - C Series

The D3-C series is the third edition of Jinghong's DOCSIS3.0 CMTS product platform. There are various product forms such as indoor type, D-node (outdoor type), and modular type to meet various deployment scenarios.

Compared with earlier versions, the D3-C series uses the latest MAC/PHY chips and a more powerful multi-core network processor from Broadcom. On the basic of maintaining the original features, its bandwidth has doubled. It can support 1000 CMs simultaneously online.

Bundled with 32 QAM channels for downstream (sharing one RF port), the data rate could be up to 2Gbps. The downstream can be configured flexibly as data channels or IPQAM channels. It also supports multicast capabilities.

Bundled with 10 QPSK/QAM channels for upstream (sharing one RF port), the data rate up to 400Mbps. It also provides the upstream spectrum analysis function.

D3-C can run in L3 or L2 mode. It has perfect QoS mechanism, built-in DHCP/TFTP/ToD servers, supports DHCP relay, and supports IPv6. It can adapt to varieties of operation environment to meet various business requirements.

There are three ways to manage the D3-C series: one is to log in through Telnet on the local machine, use the command line (CLI) for configuration management; the second is based on the embedded Web mode, which can be remotely logged into the device; the third is through network management software based on SNMP protocol and supports network management software from third parties.

D3-C series can be compatible with cable modem which conforms to DOCSIS 3.0/2.0 standard, as well as the built-in cable modem set-top box, eMTA and other terminal equipment.
