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.
