Product Description

All D3 CMTS series from Versa are developed based on DOCSIS3.0 and C-DOCSIS protocols. There are kinds of product types such as rack mount, outdoor and D-node. D3 series adopt channel binding technology, for downstream (DS), there are *6 QAM channels which has 1.1Gbps data rate; for upstream, there are 4 QPSK/QAM channels which could reach up to **0Mbps. D3's downstream can be configured to data channels or IP QAM channel. For data port, there are GE port (RJ*5) and GE optical port (SFP). With layer 3 routing function and perfect  QoS,  they can meet all kinds of working conditions and requirements from different operators. Due to D3's high bandwidth, perfect QoS, it is very suitable for IPTV or VOD, such kind of video service. It is cost effective for cut down cost then, add value for traditional HFC network. 

There are three ways to manage D3: 

CLI after log in via serial port or by telnet; 

Remote log in embed web NMS; 

External NMS server based on SNMP protocols which run windows OS. 

D3 series can compatible with DOCSIS3.0/2.0 cable modem. 

VX****0I is one of a chassis CMTS with *9 inch 1U standard chassis, it is tailor made for head end room deployment. It is suitable for small broadbanduser's scaled network. It has wide coverage and high efficiency. 

2. Features 

Compatible with DOCSIS3.0, C-DOCSIS standard, work with all cable modem based on DOCSIS, support both EURO DOCSIS and DOCSIS. 

*6 DS channels bound, *4/**6/***4QAM modulation mode optional. Data rate could reach up to *@********************US channels bound, could be configured to QPSK, **8 grade QAM mode, data rate could reach up to **0Mbps. 

Flexible on channels bound quantity set for operators convenient planning and use of channel resource. 

Layer 3 routing functions, support static route, VLAN, NAT and DHCP relay agent.

There are GE RJ*5 port and SFP on WAN port, convenient and flexible. 

Built-in DHCP/TFTP server, support PPPoE. 

Load balancing based on quantity of CM either DS or US. 

Support IPV6, multicast function. 

QoS based on service flow ensures bandwidth needs for various services. 

Ensure network transmit safety via various kinds of methods such as BPI+, CM identification, anti-DOS attack, user isolation and IP source checking. 

Support US channel spectrum analysis via Web and NMS management 

Support three management ways: CLI after log in via serial port or by telnet; Remote log in embed web NMS; External NMS server based on SNMP protocols which run windows OS.
