CMTS Cable Modem Termination System

CMTS Cable Modem Termination System gateway services to HFC network external network,broadband data and video transmission CMTS Cable Modem Termination System   Features

l      Compatible with both EURO DOCSIS1.1 & US DOCSIS1.1,it also compatible with DOCSIS2.0 cable modem.

l      Support QoS.

l      Available in both 1X1(1DS,1US) ,1 X 2(1DS,2US),&1X4(1DS,4US).

l      Available for VOIP service.

l      Customized design for cost sensitive operators

l      Support up stream frequency automatic jumping to avoid disturbing frequency point.

l      According to detecting upstream data error-code status, CMTS could estimate whether the current Working frequency points were disturbed or not .Once disturbed, the CMTS will jump frequency to spare frequency point to avoid frequency disturbing. You can set five frequency points each time.

l      Support upstream modulate mode and baud rate automatic change to insure perfect balance of Upstream transmit efficiency and the ability to resist disturbance.

l      Support DHCP relay agent and PPPoE dial-up.

l      Bandwidth limit of both upstream and downstream.

Bandwidth limit of upstream and downstream to single CM could avoid impropriating from BT downloading. Different kind of service as requested of various users offer convenient management to CATV operators.

l       Both CM and CPE could choose layer-2,layer-3 even mixed layer-2 & layer-3 working mode.

l      It can be configured and operated by CLICOMSNMP.

Log into CMTS by Telnet, configure and operate CMTS by command lines ,it is convenient for network administrator to manage and maintain both network and users as well as remote log in to upgrade all software.       

l      Optional internal high integrated DHCP/TFTP services mode.

l      While this CMTS is used for household and hotel, such kind of small network scope, it can realize most simple way broadband access by its highly integrated internal DHCP/TFTP server to reduce installation and operating cost.

l      Integrated RF digital up-converter. It is easy to set RF frequency and power level by the  VFD and function key on the panel.

l      Adopt high performance CPU to improve data processing capability.

l      Web management interface for convenient and cost effective operating.

l      Minimized 1U platform design,cost effective,easy to be piled and expanded.
