SAFETY RULES

The change from cold to hot environments can cause the formation of

condense inside the device. To avoid malfunctioning, wait at least 2 hours

before connecting the device to the supply mains.

Do not access internal parts of the device (and/or of the power supply unit).

If objects or liquids penetrate inside the device, immediately disconnect the

power supply cable. Before using the device again, have it checked by

specialised staff.

Refer to qualified staff for service.

In case of intervention, always check that the power supply has been

completely and successfully disconnected.

In case of fire, absolutely avoid using water to extinguish it.

WARNINGS

ATTENTION:

Many of the components used in this device are sensitive to

electrostatic charge.

In case of manipulation of the connection cables, disconnect the

power supply and avoid direct contacts with the connector terminals.

When handling electronic components, to eliminate any static

electricity touch a grounded surface. If possible, wear a grounding

armband.

Failure to comply with these warnings could cause permanent

damage to device.

To guarantee continuous protection for operator safety, only use the

mains adapter supplied with the instrument.

1 INTRODUCTION

With the VX2000 option, the D2000Pro is able to perform tests over WAN/datacom

lines with a bit rate up to 2.048 Mbit/s.

Thanks to the possibility to emulate both DTE (Data Terminal Equipment) and DCE

(Data Communications Equipment), the D2000Pro allows to carry out quality tests,

bit error rate (BER), in end-to-end mode over datacom line, or checks toward the

User’s DTE (CSU, router, or other WAN equipment).

The criteria monitoring and the possibility to manage local loops (LL), allow to

extend controls over datacom line.

The interfaces supported are: V.35, V.36 and V.11 (X.21),

Fig. 1-1 (single end)

The following paragraphs refer to various tests available using the D2000Pro

interface, further information about the D2000Pro are available in the User’s Manual

of the device.

1.1 Opening the Manual Test Screen

To select the manual test:

1

Open the TEST MENU.

The last used setup appears on the screen.

2

Select the ACCESS field.

3

Select the type of access, V/X INTERFACE.

Quick Guide VX2000

8

GB

4

Select the ACT AS field.

5

Select the instrument mode, e.g. DTE.

The lower section of the screen shows the selected

network configuration. The yellow LED that corresponds to

the selected mode goes on.. It’s possible to choose

between DTE and DCE

6

Select MANUAL TESTS.

7

Select the test UNFRAMED BER.

In order to connect to the line, use the appropriate cable

according to the selected mode. In case of DCE mode, an

appropriate cable, to order separately, is needed.

1.2 Common Setup

This page is used to setup the common parameters for the various tests.

1

GB

1

The COMMON SETUP page can be selected from any

test

2

Choose the desired field

The following parameters can be defined for the V/X INTERFACE access:

Interface type: Choose the interface to use among:

• V.35, V.36, V.11 (X.21)

Line rate: Select the line rate, in Kbit/s, used by the device to transmit the data.

Only if Clock TX = Inside and mode = DCE

Ignore criteria: Enable or disable the criteria control

Quick Guide VX2000

10

GB

• NO, the device guarantees and controls the C108, C107, C105, C106 and C109i

criteria

• YES, the management and the check of these criteria, between DTE and DCE, is

disabled

Clock RX: Define the type of clock used to receive data; with CLOCK RX:

LOOPED, the device samples data received with the clock coming from DTE

(C113). Only DCE.

In DCE mode, the clock TX is fixed at “INSIDE”, whereas in DTE

mode, the device uses the clock coming from the DCE over

C114 criterion.

Loop3 (C141): Set “YES” to ask the DCE to perform a local loop (LL) of the data.

Only DTE.

The LL (local loop) request is supported by V.35 and V.36

interfaces only.

1.3 UNFRAMED BER Test

In order to run a line quality test, select from the manual test menu, the

UNFRAMED BER and set the following parameters:

Duration: Choose the duration of the test. Select from the defined list or define your

own duration

Pass/Fail test: Choose the BER value. This value is used to determine the pass or

fail test condition. Selecting G.821, the result is compared with the quality

performance required by G.821. Only for line rate 64Kbit/s.

Error injection: Choose the BER value used for manual or automatic bit error

injection

Bit sequence: Set the pseudo-random pattern to be used. Select from the list

Quick Guide VX2000

11

GB

HRX(%): Enter the variation percentage for the DM and SES thresholds. Only for 1

channel bandwidth

DM Threshold: Choose the number of errors per minute to consider it as degraded.

Use the G.821 (4) default value when no other value is preferred. Only for line rate

64Kbit/s

SES Threshold: Choose the number of errors per second to be considered as

severely errored. Use the G.821 (64) default value when no other value is preferred.

Only for line rate 64Kbit/s

Auto print: Choose the autoprint condition for the test results between:

• Time interval: every 15 or 30 minutes

• DM: when the DM threshold value is exceeded

1.3.1 Running an Unframed BER Test

VX2000 adapter is fed directly by the D2000Pro, this cause a

decrease of the battery duration.

The test can be carried out both end-to-end and single end mode. In the first case is

necessary to put another D2000Pro/VX2000 at the remote end of the line (fig. 1-2).

In single-end mode, is necessary to carry out a loop over the line. The loop can be

request to DCE with C141 criterion, through a specific command given to the DCE

or carrying out a physical loop between TX side and RX side (see figure 1-1).

Fig. 1-2 (end-to-end)

When you have defined the setup for the Unframed BER test, continue as follows:

1

Select ‘Use this setup for testing’ in the first SETUP page.

2

Connect the instrument as displayed on the screen and

press the RIGHT CURSOR key.

Quick Guide VX2000

12

GB

3

Start the BER test.

The LED RUN goes on and the test results appear on the screen.

4

Scroll through the result pages.

The pages show the following results for each call:

The status line indicates the status of the test.

• Bit Error Rate (BER)

• Received bits

• Errored bits transmitted

• Errored bits received

• Synchronization and time without synchronization expressed in h, m, s (S-loss).

• Result of the PASS/FAIL test

Quick Guide VX2000

13

GB

• G.821 data: SES (severely errored seconds), DM (degraded minutes), ES

(errored seconds), US (unavailable seconds) in absolute value and percentage,

result of the PASS/FAIL test according the G.821 quality targets.

2 SMART STATUS

To have a complete description of the Smart Status feature, see the specific

chapter in the D2000Pro User’s Manual.

2.1 V/X Interface status

The 2

nd

page, relative to V/X INTERFACE access, shows the activity of the used

interface.

1

Goes to page 2.

The Clock Rx value, is displayed on the Status pages only if the

clock value has been set as ‘Looped’, in the common setup.

Selecting the relative interface field and pushing ENTER, it is possible to insert a

loop on the data, the device will send, in transmission, the data received from the

remote. Perform the same operation to remove the loop.

The 3

rd

page shows the state of criteria toward DCE and DTE

2

Goes to page 3.

Quick Guide VX2000

14

GB

The criteria displayed are:

• C103, C104, data transmitted respectively from DTE and from DCE

• C113, C115, clock transmitted respectively from DTE and from DCE

• C105 (RTS), C106 (CTS), C107 (DSR), C108 (DTR), C109 (DCD)

• C141, loop request from DTE to DCE
