1Basic Functions
The WLL550 Pro supports voice and G3-fax calls via GSM network in combination with a
broadband internet access via LTE or UMTS with HSPA+ or HSDPA and a SMS short
messaging option. Fully equipped with two radio modules all services are available at
the same time.
The sockets for fax and telephone are located on the back panel. To connect a G3 fax
machine use the connector tagged with 'Fax'. Please consider that you need a SIM-card
with an extra number for fax service. Telephone devices are connected to the 'Tel'
connector. Please use this connection for voice calls. The 'Tel' connector is also used if
the WLL550 Pro is setup as a local loop interface on a PABX. The internet connection
uses the LAN jack on the front panel. A SIM card with high speed data capabilities is
mandatory at this point.

WLL550 Pro –Operating manual
WLL550Pro_EN_V2.1.pdf -6/34 www.kuhnt.com 2015-04-10
1.1 Phone
The WLL550 Pro supplies an analogue local loop interface (FXS). This is designed for the
use with custom telephone and PABX devices (FXO/POTS). It is the basic function of all
types of WLL550 Pro. To use this basic function you need a valid SIM card, a suitable
antenna and a power supply. If your SIM is PIN protected you can execute the PIN
request by entering DTMF digits on the telephone device or within the WLL550 Pro
service session with 'AS55X-Service' software of course.
For further settings please refer to 2.1
1.2 Fax G3
The second basic feature of WLL550 Pro is a special local loop interface which supports
the operation of an analogue G3 fax machine to transmit and receive facsimiles via the
GSM mobile network.
Generally fax transmissions over the GSM network are difficult to handle because the
handshake is very time critical. For better results the WLL550 Pro splits the trans-
mission into two phases:
First the fax is submitted from the sending fax station to the WLL550 Pro buffer to be
forwarded from the WLL550 Pro buffer to the receiving fax station with a time-delay.
The WLL550 Pro tries up to three attempts to submit a fax document. During this time
the 'GSM' LED is flashing continuously and no further fax or voice call is possible via this
radio channel. However a fax transmission can fail for some reason and by splitting the
transmission handshake it might happen that the first phase of the transmission is
successful but the second phase fails. To ensure that the sender gets information about
an unsuccessful transmission the WLL550 Pro can generate a receipt for all successful
and failed fax transmissions via a response receipt.
A SIM card with an additional fax number is mandatory for fax transmissions via mobile
phone network. Incoming fax calls to this number are automatically forwarded to the
analogue fax port. Outgoing fax calls are send via radio channel two (WLL550 Pro with
two channels). All settings in global and individual call setup are exclusively for voice
calls and do not concern fax calls.
Hint: There is no fax service available within the LTE and UMTS networks.
For programming instruction see 2.2

WLL550Pro_EN_V2.1.pdf -7/34 www.kuhnt.com 2015-04-10
1.3 Internet
To fulfil the requirements for a mobile office use the WLL550 Pro can work as a
broadband-internet access which is the third basic function of the WLL550 Pro. The
related radio channel with an LTE or UMTS/HSPA+/HSDPA module is the radio channel
one. A SIM card with high speed data capabilities is mandatory in this case. Please also
check the details of your mobile phone contract for a special data tariff to avoid
unexpected high charges.
The internet speed depends on various parameters, such as the capabilities of your
mobile phone network, the local field strength quality and the operating grade of the
shared medium. Providing you have the optimal conditions an internet speed of
7,2 MB/s is possible with UMTS and up to 40 MB/s with LTE.
The WLL550 Pro connects to the internet, if valid APN information is configured
manually or when the 'Go online' box is checked in the 'Internet' settings or the DTMF
code #721# is entered on the POTS interface.
For the use with a single computer you can connect the WLL550 Pro directly to the LAN
interface of the WLL550 Pro. But you need an external NAT-router if the internet access
should be available for further network devices.
Single radio channel versions of the WLL550 Pro generally do not support broadband
internet access.
For further information please refer to 2.3 and 2.4
1.4 SMS short message
Due to the fact the WLL550 Pro has no display or keyboard an external controlling
software is necessary to manage SMS short messages.
An easy-to-use solution is the ‘SMS Center‘- client software for Windows operating
system. This is free software and it works similar to a custom messenger-client via
the WLL550 Pro LAN interface.
Use the TELNET connection or the short message-API for third party software to get
direct access to the WLL550 Pro radio modules for SMS short messaging.
‘SMS Center‘,‘SMS API‘ and ‘TELNET ‘ are 'Extended feature' that needs to be enabled
within the WLL550 Pro.
For further information please refer to 2.5

2Installation - configuration
The minimum requirements to put a WLL550 Pro into operation are a suitable power
supply, an antenna and one valid SIM card. But to supply all services a WLL550 Pro two
valid SIM cards are mandatory. One SIM for the broadband-internet access in SIM reader
of the first radio channel GSM1 with ability for LTE or UMTS/HSPA+ connections and a
second SIM with an additional GSM fax service in SIM reader of radio channel GSM2.
The connectors for the power supply, the antenna and the interfaces for phone and fax
are on the back panel of the device. The SIM readers and the LAN interface are located
on the front panel.
Usually the configuration is made with the 'AS55X-Service' configuration software via a
LAN connection. But some basic settings like entering the PIN number can be done by
DTMF sequences at the analogue telephone interface (also refer to 2.8 ). Some settings
should to be checked in a service session with the service tool.
The service tool for WLL550 Pro ‘AS55X-Service' is available as a direct download at:
> www.kuhnt.com/down/55xwin32.zip < .
If the WLL550 Pro is set to factory defaults it works as a DHCP server that can be directly
connected with the LAN of your computer. Check the network settings of your
computers network interface and activate DHCP if it is not running already.

Now select from ‘Access Type ‘> ‘Access via LAN ‘from ‘AS55X-Service' menu to start a
service session. If you are not sure about the IP of the WLL550 Pro try to detect it in your
LAN by using ‘Search for AS55X in LAN ‘.
The default IP-address of the WLL550 Pro is: 192.168.0.2 .
If you cannot access your WLL550 Pro via LAN check your LAN setup or try to reset the
WLL550 Pro to factory default by using the RESET button*. Press and hold the button
then plug in the power supply. Keep holding the button until the Power LED is on.
* Hint: Using the RESET button will delete all configuration and security data!

2.1 Phone/Fax (POTS settings)
By factory default phone and fax calls are routed via different interface . A voice call is
forwarded to the telephone interface ‘Tel‘ and all fax calls are always signalised at the
fax connector ‘Fax‘. Unless the WLL550 Pro is set to work in the ‘trunk mode‘ at a PABX
or with a Tel/Fax combination device. In the ‘trunk mode‘ all fax calls are routed via the
telephone socket ‘Tel ‘ as well.
An outgoing voice call chooses the next available radio channel by factory default. Fax
calls use exclusively the radio channel two 'GSM2' (except WLL550 Pro equipped with
just a single radio channel which uses the 'GSM1' channel only). But by configuring the
‘GSM groups ‘and the ‘ Global- ‘or ‘ Individual call setup ‘you can define your own
routing for outgoing voice calls. .
The configuration of the analogue telephone interface is made within the FXS settings
‘POTS interface settings ‘:
Operation mode / Fax call prefix:
There are two ways to run a fax machine with the WLL550 Pro. First you can
attach your phone and fax directly to its dedicated connectors. The second way is
to attach the WLL550 Pro to an analogue PBX or a Phone/Fax combo. With the
factory defaults all incoming faxes and calls are routed to individual FXS
interfaces. In ‘trunk mode’ all calls are routed to the phone connector 'Tel'. To
separate outgoing fax calls from voice calls in ‘trunk mode’, you have to dial an
additional fax prefix (e.g. *8 004944130005…) for each fax to identify the service.
This prefix (*8) is not a part of the called number is deleted by the WLL550 Pro.
Default value: Phone and fax at different interfaces
Fax call prefix
Default value: not reported

WLL550Pro_EN_V2.1.pdf -15/34 www.kuhnt.com 2015-04-10
Timeout for autostart / Amount of digits for autostart in international order –
On a FXS interface all dialling is always made digit by digit but a GSM call setup
is en bloc only. Therefore the WLL550 Pro must collect all digits until the dialled
number is complete.
We have two ways to indicate the number to be complete:
1st: Define a fix amount of digits for dialling to the GSM network. Set this
amount to the maximum number of digits referring to your destination
numbers.
2nd: Define a timeout for waiting for the next digit. After this timeout expires,
the call-setup to the GSM network starts immediately.
At the menu item 'Timeout for autostart', the timeout for waiting for the next digit
can be chosen.
Default value: 4.0 seconds
At the menu item 'Amount of digits for autostart in international order', the fix
amount of digits can be chosen. Select the maximum length of the called numbers
in international form. E.g. for the longest number [phone] select 12
digits.
Please note! If you are not sure about the maximum lengths of the number set it
to a value higher than 15.
Default value: 21

2.2 Fax function (fax settings)
To improve the fax transmission within the GSM network, the WLL550 Pro is buffering
the fax data. Sending and receiving station do not communicate directly.
Due to this two step transmission all error indications must be generated by the WLL550
Pro. If you need to know if a fax transmission has been successful or not fill in this free
form text boxes.
For further information about the fax function see also 1.2.

2.3 Configuration internet
A basic function of the WLL550 Pro is supplying a mobile broadband internet access via
LTE or UMTS with HSPA+ or HSPDA.
You can activate the internet access temporarily without the use of the service program
by DMTF code at the FXS interface. Just enter #721# with the telephone device that is
connected to the 'TEL' jack. This must be repeated if the power supply was interrupted.
Please use the AS55X-service software to activate the internet access permanently or to
enter the APN details settings manually.
AS55X-service menu:
‘GSM access ‘/ ‘Internet ‘to check the 'Go Online' box or
to enter the APN* information manually.
* Glossary / Tips
The internet access is activated by checking the 'Go Online' box or by entering the APN
information within the form fields. When the LTE/UMTS radio module is successfully
logged into the mobile phone network and WAN connection is complete the WLL550 Pro
is continuously online.
To check, whether the gateway is successfully connected to the internet or not, please
open menu ‘Services ‘/ ‘View WAN status ‘. The internet connection is ready when an IP
address and the DNS server are assigned by the proxy.
All WLL550 Pro Rev2 additionally indicate an active internet access with the 'Online' LED
on the front panel.
To disconnect the WLL550 Pro from the internet the device must be switched off or all
internet settings have be removed from the configuration setup.

WLL550Pro_EN_V2.1.pdf -19/34 www.kuhnt.com 2015-04-10
2.4 Configuration of network
To setup the internet connection some network skills are useful but not necessarily
mandatory. Usually the factory settings of WLL550 Pro is ‘default gateway with DHCP ‘
which will suite to mostly all LAN configurations. Depending on the amount of
computers that should use the internet access via the WLL550 Pro there are different
scenarios for the LAN setup of the WLL550 Pro. This is caused by the fact that it has
neither an integrated firewall nor any internal routing so all connections are directly
relayed to the connected LAN device.
- Single computer setup
If you want to connect a single computer to your WLL550 Pro, set the LAN-interface of
the WLL550 Pro to ‘default gateway with DHCP‘and activate DHCP on your computer
too. Otherwise you can configure the network interface of your computer manually. For
a manual setup first define the computer's IP within the same IP range as the WLL550
Pro and enter a valid network mask e.g. (192.168.0.3/255.255.255.0). Then set the
standard gateway and the DNS server to the IP-address of your WLL550 Pro (default:
192.168.0.2). Please note! You need a cross cable or a LAN-hub if the LAN interface of
your computer does not support ‘auto-sensing‘.
- Multi-computer/Router setup
To establish a small local network with the WLL550 Pro as internet gateway you need an
external NAT-router. The routers WAN input must be connected to the WLL550 Pro and
all computers and LAN devices to the LAN or WLAN of the router. If possible try to
establish a point-to-point connection ‘Direct connection to endpoint ‘between router and
WLL550 Pro. But the WLL550 Pro will work as ‘default gateway ‘as well if the routers
WAN interface is set to DHCP client.

2.5 Configuration of short messaging
Please connect your WLL550 Pro to a computer via LAN network. Check the extended
features (software options) of your WLL550 Pro for an ‘SMS Center‘ or ‘TELNET ‘
subscription. You need at least one of them.
The ‘SMS Center‘ is a free client software that is available at www.kuhnt.com. It uses the
LAN to communicate with the WLL550 Pro. Basic requirements are a Microsoft
Windows operation system with .NET Frameworks 2.0 or higher.
TELNET is a system-independent standard protocol to transmit modem commands via
TCP. Some applications for managing SMS short messages like ‘SMS comfort‘ are able to
access directly to the TELNET Ports of the WLL550 Pro. Others may additionally require
a virtual COM-Port driver. TELNET based application work on Apple or Linux operation
systems, too.
Please look for further information at www.kuhnt.com or ask your dealer for support.
