Application
The KE3700 / KE3550 is a fast, easy to use and cost-e󰀨ective multitester
for installing and troubleshooting DSL services in hybrid ADSL1/2/2+ / VDSL2
and bundled networks. With its variety of interfaces, it supports broadband
network technologies such as vectoring, G.fast, bonding, SHDSL*, Gigabit
Ethernet and GPON*.
Usage
The KE3700 / KE3550 provides powerful fault diagnosis for immediate trou-
bleshooting in the network, outdoor cabling, customer devices or indoor
cabling. Even in hybrid networks, where FTTH is also installed, measure-
ments can be performed on any LAN port using the Ethernet ports of the
KE3700 / KE3550. Therefore, the KE3700 /KE3550 is the ideal solution for
many broadband technologies.
Operation
With its small dimensions, robust design and intuitive operation, it is the per-
fect tester for installers and service technicians. Automatic recognition of the
xDSL service and denable test procedures enable the user to complete his
orders quickly and e󰀩ciently. The large display increases the ease of use and
when saving the results, the technician has options for exporting the tests
and compiling reports.

18 V/DC! Damage to the device due to non-observance will be repai-
red at the owner‘s expense!
Always plug the power supply unit into the device rst and
then into the power outlet.
Note: Please fully charge the battery before rst use!
If the charge control LED changes from orange to green, charging is
complete. To check the charge indicator after initial charging, switch
the unit o󰀨 and on again for approx. 1 minute with the power supply
unit connected. During this time, the battery display calibrates and
shows the correct value.

Analysis
You can call up stored broadband and
copper measurements and analyze
them in the device. Not only the stored
snapshot is displayed, but the entire
measurement sequence from the start
of synchronization. In the selection
menu you can start the display with
F2 <Info> (depending on the duration
of the synchronization time this can be
a longer process). With F3 <Edit> you
can rename a measurement le and
with F4 <Delete> you can delete the
le. Since the display is not an active
representation of the measured values,
it is displayed with a di󰀨erent backg-
round colour and a red border.
Address book
In the Address book, you can create
phone numbers, IP addresses, VoIP
access data and SIP details, frequently
used URLs, user names and pass-
words.
With F1 > Add contacts you can crea-
te a new address entry and add details
to the categories above mentioned in
the next menu with F2.
These can then be called up in the cor-
responding menus (with the key)
and you do not have to repeat the entry.

For ISDN S0NT tests, please use the included red ISDN connection
cable.
ISDN and Analogue interface
(option)
The KE3700 / KE3550 with its optional
ISDN interface covers all functions for the
installation and maintenance of S0-/NT
and Uk0- as well as analogue connections:
It checks S0interfaces in TE, NT and
xed connection mode. You can choose
between the connection types Analogue,
ISDN S0TE, ISDN S0NT and ISDN Uk0.
VoIP (option)
The KE3700 /KE3550 works as a VoIP
terminal with active telephone function.
VoIP connections can be established via
xDSL and Ethernet. SIP (Session Initiati-
on Protocol) is available as VoIP signal-
ling protocol. To assess the voice quality,
the MOS and R-factor are determined and
displayed on the basis of the data stre-
am. All settings can be stored in proles
(xDSL, Ethernet and Wi-Fi).
IPTV (option)
IPTV proles are uploaded to the KE3700 /
KE3550 using the KE Manager. The de-
vice requests a data stream from a server
(replaces the set-top box (STB) or modem
depending on the connection type) and
checks the regularity of the incoming pa-
ckets, the loss of packets and the switch-
on or switch-over time of the program.

© Kurth Electronic GmbH, All Rights Reserved 13
Wi-Fi (option)
In addition to wired networks, you can also
connect wirelessly to a network that sup-
ports the IEE802.11 standard. In addition
to the ability to use a wireless network for
Internet access, you can also perform ge-
neral network tests and view the status of
the wireless access point.
Conguration
Select the interface <Wi-Fi> from the main
menu. You can now connect to a Wi-Finet-
work under Wi-Fi interface:
Select Network: Select an accessible
network and automatically connect to it if
necessary by entering the password. Here
you can also see the channel, the MAC ad-
dress and the signal strength of the access
point.
Manual network: Connect to a known
access point by manually entering all re-
quired data.
WAP: Automatically connect to an access
point via WAP.
Evaluation
The conguration and evaluation of net-
work tests via Wi-Fi works exactly as you
are used to from the other interfaces.

KE-Manager Software
You install the KE Manager software on your PC by double-clicking on the
setup le in the Explorer window. A Windows installation wizard guides you
through the necessary steps.
Connect the Multitester to your network /PC
Switch on the xDSL Multitester. Use an RJ45
Ethernet cable and connect the Multitester
via the management port (top of the device)
to an Ethernet port on your network or direc-
tly to the Ethernet port on your PC.
Starting the KE-Manager
Click on the KE Manager icon on your PC desktop. The KE
Manager loads and shows you the connection status to the PC
using various colours.
The connection status is displayed in the bottom line:
– Please click on a device to connect
– KE3x00 found → Connection to IP 192.xxx is established
– Connection to KE3x00 (serial number, IP 192.xxx) is OK
The green background indicates the established connection. The serial num-
ber and IP address are displayed in the window in the upper left corner. If
there are several KE multitesters in the network, you can nd the one you are
looking for by viewing the serial number. Now you can make settings for the
KE Multitester via the KE Manager.

The KE-Manager is a exible tool for managing the KE3700 / KE3550 and for
downloading measurement data. Like the KE3700 / KE3550, the KE-Manager
is well arranged and largely intuitive to operate.
Conguration
Creation of proles, settings
for basic options such as lan-
guage selection and licensing
as well as uploading channel
lists (IPTV proles) and up-
dating the device rmware.
Detailed update instructions
are stored in the KE Manager
under Help.
Result Centre
Gives precise information
about the active and stored
tests. Available for xDSL,
Ethernet, SHDSL and evalua-
tion of test errors. The display
of the parameters is individu-
ally congurable.
Important: Always connect
the KE Multitester to the
power supply before star-
ting the update process! If
you unintentionally switch
o󰀨 during the update, you
will have to send in the
device.

Firmware update
You can use the KE Manager to install rmware updates on your KE3700 /
KE3550. We recommend that you keep your device‘s rmware up to date to
take advantage of latest features and optimizations. The currently installed
rmware version can be viewed in the device under Setup > System Infor-
mation.
You can always download the latest rmware from our homepage at
www.kurthelectronic.de/software-downloads/?lang=en.
Click on Conguration in the KE Manager menu bar. A new window opens:
In the conguration menu you can select the desired language and press the
button Update Firmware at the bottom right for the software update.
You can select the KE-Multi-
tester rmware le from your
hard disk or an external drive
via the Explorer of your PC
(the les always have the ex-
tension .upd ). In the selection
window, click Open.
The KE-Manager checks
whether the selected rmwa-
re is more current than the
rmware already installed on
the KE Multitester. You can
then start the upload of the
le to the device. After suc-
cessful transfer, install the
new rmware on the device.
Once you have uploaded the.upd le to the device, the Software Updates
menu item under Setup is activated.
Warning: Do not perform software update with a SFP module plugged in!
Only perform the update with the power supply connected!

18
The update process is initiated by selecting this menu item. After this auto-
mated process, the device is restarted. If several modules are to be updated,
you may also need to initate their pending updates.
Activation of software options
You can activate software options for your device via the KE Manager. To do
so, connect the manager to your device and select the Licencing tab in the
Conguration menu item.
A window with available soft-
ware options of your device
and the activation status
opens. To unlock another
software option, double-click
on the desired option and en-
ter the corresponding license
key. After successfully ente-
ring the key, the option is acti-
vated on your device within a
few seconds and is available
after a restart.
