High efficiency Docsis 3.0 Cable Modem DOCSIS Devices High bandwidth

 
High efficiency 1U Indoor Docsis 3.0 , High bandwidth DOCSIS Devices Wide coverage Chassis CMTS
 
Overview

All LTCMTS100H CMTS series from Lootom are developed based on DOCSIS3.0 and C-DOCSIS protocols.
 
There are kinds of product types such as rack mount, outdoor and D-node.
LTCMTS100H series adopt channel binding technology, for downstream (DS), there are 16 QAM channels which has 1.1Gbps data rate; for upstream, there are 4 QPSK/QAM channels which could reach up to 160Mbps. LTCMTS100H’s downstream can be configured to data channels or IP QAM channel, for data port, there are 1000Mbps power port (RJ45) and 1000Mbps 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 LTCMTS100H’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 LTCMTS100H: use CLI after log in via serial port Telnet, use CLI to realize remote log in via web and use network management software based on OAM.
 
LTCMTS100H series can compatible with DOCSIS3.0/2.0/1.1/1.0 cable modem.
 
 LTCMTS100H is one of a chassis CMTS with 19 inch 1U standard chassis, it is tailor made for front end room deployment. It is suitable for small broadband user’s scaled network. It has wide coverage and high efficiency. Completely isolated upstream channels can reduce the funnel mixture noise, 8dB. With the large screen panel display, users can check all parameters, real time running status and upstream spectrum analysis directly.
 
 Features

• 4 US channels bound, could be configured to QPSK, 3-8 grade QAM mode, data rate could reach up to 160Mbps.
• Flexible on channels bound quantity set for operator’s convenient planning and use of channel resource.
• Layer 3 routing functions, support static route, VLAN,NAT and DHCP relay agent.
• There are 1000M RJ45 port and SFP on data port, convenient and flexible.
• Built-in DHCP/TFTP server, support PPPoE.
• Load balancing.
• 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.
• Real time upstream spectrum analysis function which helps to check US channel signal and noise status rapidly.
• 4 upstream channels could be choiced physical independent, reduce 8dB overlay return noise from the combination .
• Support three management ways: use CLI after log in via serial port Telnet, use CLI to realize remote log in via web and network management software based on SNMP.
