D3-B Series
D3-B family is the upgrade version of D3 family, running DOCSIS 3.0 and C-DOCSIS protocol. The D3-B family includes the following forms of CMTS: compact rack-mountable type (1U), high-density type(3U) and D-node type (outdoor).
The benefits of D3-B family over D3 family are listed as follows:
◆ Upgrade from Dual core to Quad core processor for data forwarding;
◆ Upgrade from DDR2 to DDR3 RAM;
◆ Improved power management;
◆ Migrate to Linux operating system;
With these changes, the D3-B family provides faster forwarding capabilities and larger throughput for IP packet (especially smaller size packet or fragment packet are optimized).
All D3-B family products implement CMTS channel bonding technology, providing up to 16 QAM channels with total 1Gbps for DS (Down-Stream), and up to 4 QPSK/QAM channels with total 160 Mbps for US (Up- Stream). The DS can be easily configured to run as either data channel or IPQAM channel. It provides both electrical (RJ45) and optical (SFP, 1.25Gbps) connection for data forwarding. D3-B family also implements layer 3 routing function, QoS, DHCP/TFTP services, and DHCP relay.
Users have 3 management methods, including CLI withTelnet, Web interface and third-party tool via SNMP.
◆ Users can use CLI by login with Telnet (direct connection to the CMTS).
◆ Users can remote login to the CMTS embedded web interface through internet.
◆ Users can use third-party Network Management System that supports SNMP to manage the CTMS.
D3-B family is capable to run with DOCSIS 3.0/2.0 client cable modems, set-top boxes (built-in with modems) and eMTA.
