Copper, VDSL2, ADSL2+ and IP Triple-Play Test Set vii
1 Introducing the Copper,
VDSL2, ADSL2+ and IP
Triple-Play Test Set
The AXS-200/635i Copper, VDSL2, ADSL2+ and IP Triple-Play Test Set is a
handheld unit that integrates the functionalities of the AXS-200/610 30 MHz
Copper Test Set and the AXS-200/630 VDSL2, ADSL2+ and IP Triple-Play
Test Set. The AXS-200/635i allows you to qualify and troubleshoot the
copper-loop plant and triple-play services from top to bottom by using
pass/fail-driven automated functionalities with one consolidated test set.
In addition to validating connectivity to the DSLAM, the AXS-200/635i
provides upstream and downstream parameters such as actual data rates,
attenuation and noise margin. It delivers advanced IPTV measurements:
packet jitter, packet loss, PCR jitter, MDI, PID viewer, and IGMP zap time;
both in Terminate (stand-alone) and Through mode operation. The
AXS-200/635i also monitors residential VoIP call flow and statistics,
facilitating VoIP QoS assurance.
Main Features
³ Clear Auto Test results with user-definable pass/fail criteria.
³ VDSL2, ADSL2+, AUTO-DSL, Ethernet and HPNA-coax tests in a
single unit.
³ IPTV testing over existing legacy DSLAMs (Lucent Stinger -
VDSL2-STGR) and newer solutions (Alcatel 7330 - VDSL2-ALCL).
³ Key IPTV qualification parameters with features such as set-top box
(STB) emulation, join/leave requests, PCR jitter analysis and MDI
reporting.
³ Superior network testing such as ping and traceroute measurements
as well as HTTP and FTP speed testing.
³ 30MHz spectrum analysis for single-ended VDSL2 pre qualification and
deployments; backward-compatible to ADSL2+.
³ Verification of traditional voiceband circuits

Introducing the Copper, VDSL2, ADSL2+ and IP Triple-Play Test Set
Main Features
Typical Applications
The AXS-200/635i allows you to test outside the customer premises over
VDSL1.5/2, ADSL1/2/2+ or inside over Ethernet. Both modes allow you to
use the Copper, VDSL2, ADSL2+ and IP Triple-Play Test Set for several
applications, such as:
³ IPTV analysis
³ Data analysis
³ VoIP analysis
³ Manual tests
³ Auto tests
In addition, the unit can be configured to run a series of fault isolation tools
to see if the cable is suitable for carrying digital subscriber line (DSL)
technologies such as:
³ POTS auto test
³ Multi-meter tests
³ VF tests
³ Fault location tests
³ Wideband tests

Red indicates that test
results have failed the
thresholds.
Green indicates that test
results were evaluated
against the
customer-defined

Electrical Safety Information
Do not use the unit outdoors in wet locations. For information about
equipment rating for temperature, environment, and power supply, refer to
the Safety Information chapter of the AXS-200 User Guide.
Introducing the Copper, VDSL2, ADSL2+ and IP Triple-Play Test Set
ADSL2+ Basic Principles
ADSL2+ Basic Principles
ADSL2+ based testing requires an ATU-C (ADSL Transceiver Unit - Central
Office) that resides in a DSLAM (Digital Subscriber Line Access Multiplexer)
in the Central Office/Local Exchange. At the customer premises, there is an
ATU-R (ADSL Transceiver Unit - Remote) that interfaces with a user's PC.
The Copper, VDSL2, ADSL2+ and IP Triple-Play Test Set allows you to
emulate the ATU-R (customer’s ADSL modem). Once a connection is
established with the ATU-C in the DSLAM at the service provider’s central
office or remote DLC, the AXS-200/635i displays the connection rates for
the upstream and downstream directions of the ADSL2+ link.
VDSL2
Very high speed digital subscriber lines (VDSL) is a standard that allows
extremely high speed internet access over existing copper cables. The
VDSL2 standard increases the spectrum allocation up to 30 MHz for even
higher performance than its predecessor VDSL1, and allows speeds up to
100 Mbps symmetrical (both up and downstream). VDSL2 also calls for
support of applications such as multi-channel high definition TV (HDTV),
video on demand, video-conferencing, and VoIP using the existing copper
telephone line infrastructure. Along with that, it also calls for ATM, Ethernet,
and IP compatibility, as well as multimode implementations to permit
interoperability with existing ADSL equipment.
VDSL2 gives carriers the flexibility to start rapidly deploying VDSL2
networks and offer new broadband services including triple-play services HDTV, VoD, high-speed data, VoIP, high-speed Internet access, video
conferencing, virtual private networks (VPNs), PBX Extension, and video
surveillance - to compete with cable companies.

Isolation Tools
The AXS-200/635i is designed to test basic twisted pair quality, identify and
locate faults, perform advanced single-ended loop tests, and troubleshoot
noise and signal issues all the way up to 30 MHz in support of the VDSL2
standard. These measurements offer a quick and thorough method to
determine if the cable is capable of supporting xDSL technology. In
addition, it utilizes noise measurements, longitudinal balance tests, and
power spectral density tests to assist in the installation, maintenance, and
troubleshooting of copper cables.
Note: Tests can be accessed and run directly from the Home menu.
To access/run fault isolation tools:
1. On the Home pane use the
up/down arrow keys to highlight
any one of the easy-access fault
isolation tools: Multi-meter,
Inactive Pair Test, Final/Active
Pair Test, or Fault Location, then
press .

Dialer Function
Dialer Function
The Dialer function provides a dial-up path from the AXS-200/635i to
another tester (or quiet termination or silent switchman) through a
switched circuit network. DTMF transmission is enabled via the AXS-200
keypad allowing you to place and receive POTS calls. The dialer can be
accessed from the Home pane and is also integrated into individual test
screens to give you quick access to the manual dialer function, speed dial
and last dialed lists, without exiting the current test application.
Dialer
The Dialer menu item/tab allows you to use the unit as a telephone (with a
headset) and the AXS-200 keypad as a dialer keypad when the Dialer is
invoked, whether in the test results screens or through the separate
dedicated Dialer application. It goes off hook immediately when entered
from the menu or when switched from another tab.This allows you to
quickly check if the circuit under test has dial tone or is a digital service.
Each parameter and button are described below:
³ The edit box is where you enter
the phone number you wish to
dial. You can add this number to
the Phone Book by pressing the
Add to Phone Book button.
³ Dial button is enabled whether or
not there is a number present in
the edit box. If there is a number, it
will be dialed. If not, pressing the
