CMTS & NMS

Highly integrated DOCSIS compatible CMTS with excellent

performance. Compatible with both DOCSIS1.1 &

Euro-DOCSIS1.1.

1. Feature

Compatible with both EURO DOCSIS1.1 & US DOCSIS1.1，it also compatible

with DOCSIS2.0 cable modem

Support QoS

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

Available for VOIP service

Support up-stream frequency automatic jumping to avoid disturbing frequency

point

According to detecting up-stream 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

Support up-stream modulate mode and baud rate automatic change to insure

perfect balance of up-stream transmit efficiency and the ability to resist

disturbance

Support DHCP relay agent and PPPoE dial-up

Bandwidth limit of both 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 operators.

Both CM and CPE could choose layer-2, layer-3, even mixed layer-2 & layer-3

working mode.

It can be configured and operated by CLI、COM、SNMP

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.

Optional internal high integrated DHCP/TFTP services mode.

While this CMTS is used for household and hotel, such kind of small network

scope, it can realize most simple way broadband access by highly integrated

internal DHCP/TFTP server to reduce installation and operating cost.

Integrated RF digital up-converter. It is easy to set RF frequency and power level

by the VFD and function key on the panel.

Adopt high performance CPU to improve data processing capability

Web management interface for convenient and cost effective operating

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

expanded.

Network Management Software

Ensuring data transmit stability and safety of all configuration, monitoring,

maintaining, operating and security warning system of CMTS, cable modem,

CPE etc. Based on SNMP agreement, this software adapts intuitionistic

and laconic all English interface and combined with characteristics of CMTS

and its CM system network management software. NMS is mainly used to

ensure security and normal running of network transmission channel (both

upstream and downstream) and real time omni bearing detection to equipment

itself and network transmission channels. Once abnormities occurred, it will

warn related principal. It helps CATV operator to establish “manageable &

administrable” network platform and cut cost of operating to ensure its

stability and continuable development. This software, several CMTS under the

same interface can be managed concentrately which greatly cut the cost of

user and improved system administrator’s management efficiency. Meanwhile,

its remote control management function enables safe remote control of CMTS

on optical nodes and branch front end displaced in the front end.
