JH-HE 2086 CMTS Operation Guide

This chapter mainly describes the appearance characteristics, installation, configuration and how to deal

with general breakdown of the JH-HE 2086 CMTS with examples.

ummary

1

Brief Introduction

Chongqing Jinghong High-tech Co., Ltd is a professional manufacturer of CMTS (Cable Modem

Termination System) equipment in China. Since the first CMTS being produced in January 2000, we

have launched several models of products in CMTS series.

JH-HE 2086 is a new generation of CMTS that we launched in March 2007. Based on its original model,

this improved version has a bunch of remarkable new functions. The product is compliant with

DOCSIS1.1 standard. It offers not only gateway services to HFC network and external network, but also

broadband data and video transmission services that based on IP. It is especially suitable for the Cable

TV operators and Multi-service operators (MSO) to offer stable and reliable broadband services for their

Bidirectional HFC network users.

JH-HE 2086 CMTS adopts 1U structure. It has integrated digital upconverter so that users can set

proper downstream frequencies according to the network situation discretionarily. The equipment has

four upstream channels and one downstream channel.

JH-HE 2086 CMTS use QNX OS a distributed, embedded, real-time operation system similar to UNIX

(in accord with POSIX) - as its operation system.

Features

Compatible with both EURO DOCSIS1.1 & US DOCSIS1.1it 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.

Customized design for cost sensitive operators

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

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.

Support upstream modulate mode and baud rate automatic change to insure perfect balance of

Upstream transmit efficiency and the ability to resist disturbance.

Support DHCP relay agent and PPPoE dial-up.

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.

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 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.

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 its 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.

Note Pay especial attention to differentiate the input and output marks when coaxial cable

connect with the splitter

It is important to maintain reliable earthing (also known as grounding) of

rack-mounted equipment. Make sure that the rack you use for the system is properly

earthed at all times.

Turn on and turn off

3.1 steps of turning on the equipment

Turn on the CMTS power source.

About 30 seconds after CMTS turned on, system prepares to be ready.

Connect a CM to test whether the CMTS works normally. If the CM can smoothly connected, it

indicated that the CMTS runs normally.

3.2 steps of turning off the equipment

normally turn off: you should input "shutdown", 5-50 seconds later, shut off the power

on special conditions, if really necessary to turnoff CMTS, you can shutdown power directly

The input level of Cable Modem4575 dBVmaximum not exceeding 90dBV;

The SNR of HFC network upstream is required not below 20 dB. DOCSIS protocol requires the

indices not below 25dBthere is in favor of allowance

Note the effective way to detect whether bidirectional HFC network fits for CMTS operation is: user

transmits a signal that frequency range is 5-42or 65MHz 100 dBVyoud better use a signal produce

instrument. If the incoming level of CMTS reaches 60 dBV it can satisfy the equipment operating

requirement. The power level of every upstream signal that entering upstream mixer should be the

same.

DHCP relay agency configuration

This part mainly introduces the conception of DHCP relay agency and its mode. It also presented how to

configure and test DHCP server

. DHCP relay agency

The relay agent is a procedure that transfers DHCP / BOOTP info between client PC and server in

different subnet. According to RFC, a standard documentation describes protocol design and relative

operation, DHCP/BOOTP relay agent is a part of DHCP and BOOTP standard and function.

DHCP relay agent transfer broadcasting mode DHCP/BOOTP info from one of its connected physical

port (e.g. both upstream and downstream channels ) to other physical ports even other long-distance

subnet.

Jinghong CMTS DHCP relay agent function can transfer DHCP requests from network of CM, CPE and

DHCP server then divided CM and CPE into different network section.

Setup CMTS network parameter and realize DHCP relay agent

In those network of CM and CPE (HFC plant), CMTS, as gateway, needs to configure gateway add. Of

CPE and CM (please check network management software user manual for more details). The gateway

adds Should be at the same network section as CPE and CM that worked under DHCP field but can not

conflict with each other.

In order to enable the DHCP requests could be sent to correct DHCP server, you should setup DHCP

server IP add on CMTS. (Please check NMS user manual 6.3 for more details)

Suppose that an HFC plant IP programming is as follows: (all later parameters in this article should take

this supposed parameter as the standard)

1CM IP add is172.16.4.0 / 22

2CPE IP add is172.16.8.0 / 22

3DHCP server and CMTS Ethernet network is 172.168.0.0 / 24more details are as follows

Configuration of CMTS is just one of the part to realize DHCP relay agent , on the other side, you have to

configure the DHCP server, the procedure is as follows:

Confirm TFTP Server root default route, click ok

Deploy static router on DHCP server

If CM or CPE works at layer-3 router mode, the CMCPE & DHCP server will work at different network,

therefore, the DHCP server will send info to CM/CPE, It must make sure that gateway sent to CM/CPE

CM gateway IP add172.16.4.1 mask code255.255.252.0the gateway of network 172.16.4.0 / 22

CPE gateway IP add172.16.8.1 mask code255.255.252.0the gateway of network 172.16.8.0 / 22

Configuration of static router of DHCP server is as following:

Purpose network172.16.4.0 mask code255.255.252.0 gateway 172.168.0.200(cmts WAN access)

Purpose network172.16.8.0 mask code255.255.252.0 gateway 172.168.0.200(cmts WAN access)

Note

The external network router related to CMTS must be setup to CPE network static router then the

CPE could visit that external network.

VDHCP relay agent funct ion test

Establish a simple network status, connect one CM at least. Pay attention to that whether the CM could

got IP add of CM working field after distance measurement and whether it can download configuration

files successfully after got the IP add.

Once the CM got IP add and download configuration files and then register successfully, connect at least

one PC to CM, setup it into automatically got IP add mode. Detect whether the PC could got IP add in

the CPE working field.

All mentioned above successfully tested, it indicates that the DHCP relay agent works at a normal

status.
