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.

Summary

1Brief 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 OSa distributed, embedded, real-time

operation system similar to UNIX (in accord with POSIX) - as its operation system. 2Features

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


8/20

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, itcan 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 function key on the panel. Adopt high performance CPU to improve data processing

capability. Web management interface for convenient and cost effective operating. VFD and

Minimized 1U platform designcost effectiveeasy to be piled and expanded. 3

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

not below 25dBthere is in favor of allowanceNotethe 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 presentedhow 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

indifferent 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


14/20

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

a PC to DHCP server to see whether it can acquire right IP address.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 points to CMTS WAN access. See as following: 1CM IP add is172.16.4.0

gateway172.168.0.200(cmts WAN access) NoteThe 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 function 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 registersuccessfully, 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.

The methods to control the quantity of the CM and to band the MAC address

Operation step

1. Handtailor special configuration files for the CMs which need to limit the number of PC and tie

the MAC to PC. 2. Put the configuration file to the list that the TFTP severs selected. 3. Hold an IP

address for the CM in the action scope of DHCP servers. 4. Configure the action field in the

reserved address. Change the configure files name in the option into the configure files name

which the CM cunstom-builted. 5. After restart the CM, it will download the configure files. The

files include the information about the number of PC and the MAC address. 6. Configuration goes

into effect when the files download successfully. Connect a HUB with CM, and connect a PC with

HUB. PC cant get rightIP address when the MAC addresses of PC net card and that set in the

configuration files are different.

Create configuration files

1About configure files builder Configuration files editor is a professional tool software. It can

create configuration files based on the necessary. For example, it can configure the PC quantity

that connect with the CM (16 at most), configure the highest upstream rate(bit/s), tie the MAC

address of the PC net card that connected with theCM. There are various kinds of configuration
