1. Introduction

This document is intended for First Office Acceptance test plan for NetComm’s ADSL2+ Broadband Access Switch solution (BAS). The Netcomm NCT240 Broadba nd Access Switch
contains 24 ADSL2/2+ circuits to deliver high-speed data, video and voice service over traditional twisted copper pairs by using DSL technology.
To meet the increasing demand for high-speed internet access and triple play application services. The next generation network offers a feasible functionality of integrated services with the most cost effective architecture. Next generation broadband access networks are designed to provide rich video contents, DSL , POTS and VoIP services over traditional copper wire infrastructure. These types of services will be supported on NGN architecture simultaneously. DSL is used as the data service platform for traditional POTS technology which is used for voice services. The multimedia and local content-rich appl ication s can als o be easily implemented on this NGN architecture.
xDSL (Digital Subscriber Line) is a technology for delivering high-bandwidth information over copper telephone lines. xDSL service can deliver POTS and high date rate services simultaneously over a single twisted-wire pair. The POTS and data service are simultaneous and independent; the xDSL data service does not affect the POTS service. xDSL uses the bandwidth above the 4-kHz POTS frequency to transmit duplex data using digital modulation techniques from the C.O side to the Customer Premises Equipment (CPE).
ADSL is a form of xDSL service that delivers an asymmetric data rate over a twisted copper pair. ADSL delivers a h igher rate downstream, towards the cust omer premises and lower rate upstream, from the customer premises. ITU standard compliant Full-Rate ADSL2+ can deliver data rates up to 25 Mbps downstream and 1 Mbps upstream; Full-Rate ADSL can deliver data rates up to 8 Mbps downstream and 800 kbps upstream; G.Lite ADSL can deliver up to 1.5 Mbps downstream and 512 kbps upstream. The actual data rate depends on the length, gauge, and condition of the twisted-wire pair, the bandwidth of the uplink depends on the data network, and the capacity of the network service provider.
Digital Subscriber Line (DSL) dominates broadband market. The position of national telecom operators in most countries has given the advantage in reaching out to customers with broadband services over DSL.
NetComm NCT240 Management Guide Release 1.0
The NCT240 Access system contains 24 ADSL2/2+ circuits to deliver high-speed data service over twisted copper pairs using industry standard Discrete Multi-Tone (DMT) line coding technology. The NCT240 complies with full-rate ADSL in accordance with ANSI T1.413 Issue 2, ITU-T G.992.1 (G.dmt), ITU-T G.992.2 (G.lite)ITU-T G.992.3 (ADSL2) and ITU G.992.5 (G.ADSL2+) protocols.
The NCT240 greatly expand broadband capabilities in the access network, enhancing the infrastructure for emerging services. With simple in-service upgrades, service providers obtain the capacity and Quality of Service (QoS) to support larger populations of narrowband and broadband users. For management, NCT240 can be easily configured by SNMP, Telnet, SSH, HTTP, HTTPS and RS-232 console.

This chapter introduces the command line interface and lists the available commands.
It is divided into 7 topics:
1. System:- Deal with system configuration and maintenance.
2. ADSL:- Introducing and configuring ADSL parameters.
3. Status :- Display the system status
4. Switch:- Deal with Switch functions, such as activates and configures IGMP,
RSTP and other protocol parameters. (NOTE: some of the functions describe in this topic is still under development).
5. IP:- Deal with IP (Internet Protocol) param eters configuration.
6. Statistics:- Deal with Error performance and statistic counters.
7. Config:- Deal with system parameters and display settings.
After login, help command can be accessed at any time. Help command can be accessed by typing “help” or a “h”. Help command lists all the available commands that are accessible to the user. The following is a screenshot of the system.
BAS0>help
help Display command list ? Display command list < sys > < adsl > < status > < switch > < ip > < statistics > < config > exit Return to upper level
Figure 1: Help menu under root directory
Figure 1 showed all the commands under root directory. User can access different directory by typing the corresponding directory name. For example, to enter system directory, just type “system” or simply “sys”. To return to parent directory, just type “exit”. To end CLI session, type “end” under root directory.
NetComm NCT240 Management Guide Release 1.0

Command format

Some commands required parameter(s). The number of parameter required is different for each command. To know each command’s parameters, just type the command name. For example, to know the command format for XXX, you can type XXX; the screen will show something like this: XXX <aaa|bbb|ccc|ddd> <eee|fff> [ggg] Each set of “<>” bracket represent a parameter and the possible options are enclosed within the bracket, separated by “|”. The option enclosed in the square bracket “[ ]” means this parameter is optional. In this example, we can see that command XXX has three parameters. There are 4 possible options for 1st parameter, namely aaa, bbb, ccc and ddd, and two possible option for 2nd parameter, namely eee and fff, and an optional 3rd parameter. For the command to be executed, you can either type: XXX aaa eee ggg or XXX aaa eee Both of them are valid input, since this command takes two OR three parameters.

ADSL:

This chapter explains how to configure NCT240 system’s ADSL ports. It also covers how to configure virtual channels and virtual channel profiles. A profile is a table that contains a list of pre-configured ADSL settings. Each ADSL port has one profile assigned to it. The profile defines the latency mode and upstream/downstream latency delay maximum and minimum upstream/downstream rates, the target upstream/downstream signal noise margins, and the maximum and minimum upstream/downstream acceptable noise margins of all the ADSL ports that have this profile. You can configure multiple profiles, including profiles for troubleshooting.

4. Troubleshooting Troubleshooting guide

Trouble PWR indicator does not light up after power on.
SYS indicator does not light up after startup.
ADSL2+ LINK
indicator does not light up after making a connection.
Possible cause
Power outlet, power cord, or internal power supply may be defective.
Microprocessor, SDRAM, Flash or Software may be defective.
NCT240 Switch, cabling, ADSL Line, or ADSL Switch Ports may be defective.
Solution
• Check the power outlet by plugging in another device that is functioning properly.
• Check the power cord with another
device.
• Verify that the switch is powered on.
• Check the boot-up statement from console. The boot up procedure is Boot -> kernel->application
•
• Verify that the Access Switch and attached CPE are powered on.
• Be sure the RJ-21 cables are plugged into the Access Switch from ADSL2+ modem through the Phone-line punch-down block.
UP LINK indicator does not light up after making a connection.
Network cable or Ethernet device attached to this port may be defective.
• Verify that the cable length does not exceed specified limits.
• Check the cable connections on the access Switch, punch-down block/patch panel, and the Extended Ethernet CPE for possible defects. Replace the defective cable if necessary.
• Verify that the access switch and attached device are powered on.
• Be sure an Ethernet cable is plugged into both the switch and attached device.
• Verify that the proper cable type is used and its length does not exceed specified limits.
• Check the network cable connections for possible defects. Replace the defective cable if necessary.
