3.3 Frequently asked questions
This section provides solutions to problems regarding your MicroLink 56k Fun
II, which our support team has already worked through for other customers.
Question How can I configure an analog modem for a private
branch exchange (PBX)?
The analog modem is connected to a PBX. A connection cannot be
established. Every time a dial sequence is run, the following messages are
displayed:
'Error 680: No dial tone'
'Error 678: The dialed computer is not answering' or 'Error 678: No
answer'
Cause A PBX requires a number for accessing an outside line. Usually this is
specified with a single digit (0-9), while some systems use several digits or
the flash button. When you first setup your Internet connection, Windows
prompts you to enter this number in the 'General Information'. Even if the
number for accessing an outside line is entered, problems can occur when
trying to establish a connection. If this is the case, check the following
settings:
Solution (1. disable
dial tone detection) With the Windows standard configuration, the modem waits for a
dial tone before dialing. This function has to be disabled.
Windows 98
Under My Computer Dial-Up Networking, click the dial-up connection
you have created with the right mouse button. Under the 'Properties' entry,
click Configure. On the 'Settings' tab, disable the 'Wait for dial tone before
dialing' option.
Windows Me
Under Start  Settings  Dial-Up Networking, select your dial-up
connection using the right mouse button. Under the 'Properties' entry, click
Configure. On the 'Connection' tab, disable the 'Wait for dial tone before
dialing' option.
Windows 2000
Click Start Settings Control Panel Phone and Modems Options.
On the 'Modems' tab, select your modem. Click on Properties. On the
'General' tab, disable the 'Wait for dial tone before dialing' option.

|Appendix 15
|devolo MicroLink 56k Fun II |
EN
Windows XP
There are various ways to configure this aspect under Windows XP. For more
information, please refer to your Windows XP documentation.
Click Start Control Panel Printers and Other Hardware Phone
and Modems Options. On the 'Modems' tab, select your modem. Click on
Properties. On the 'General' tab, disable the 'Wait for dial tone before
dialing' option.
For advanced users: The dial tone can also be ignored by using the AT
command X3. This is entered in the modem properties under 'Advanced' in
the 'Extra Settings' field.
Solution
(2. specify
numbers for
outside lines)
A PBX requires a number for accessing an outside line in order for a
connection to be established.
Windows 98
Select Start Settings Control Panel  Modems and select your
modem. Click Dialing Properties and enter the numbers needed for
accessing an outside line for both local and long-distance calls.
Windows Me
Select Start Settings Control Panel  Modems and select your
modem. Click Dialing Properties and enter the numbers needed for
accessing an outside line for both local and long-distance calls.
Windows 2000
Under Start Settings Control Panel Network and Dial-up
Connections, select the connection you have created by clicking it using the
right mouse button. Under 'Properties', enable the option to Use dialing
rules. Click Rules and then Edit. Now enter the numbers needed for
accessing an outside line for both local and long-distance calls.
Windows XP
There are various ways to configure this aspect under Windows XP. For more
information, please refer to your Windows XP documentation.
Under Start Control Panel Network and Internet Connections 
Network Connections, click the connection you have created using the
right mouse button. Under 'Properties', enable the option to Use dialing
rules. Click Dialing Rules and then Edit. Now enter the numbers needed
for accessing an outside line for both local and long-distance calls.

Appendix |
|devolo MicroLink 56k Fun II |
16
EN
For advanced users: Numbers for accessing outside lines and wait commands
can also be typed in manually in front of the phone number. Because a delay
can occur after the number for an outside line is dialed and before the outside
line is connected by the PBX, you may have to specify pauses between the
outside line number and the phone number (indicated by one or more
commas, for example: 0,,12345), or better yet, use the wait command (w). For
most private branch exchanges, 0w (e.g. 0w12345) is sufficient. Under
Windows 2000, letters cannot be used in dialing parameters. Instead, use
commas after the outside line number (e.g. 0,,12345).
Question What are driver and software signatures?
When installing software under the Windows 2000 and Windows XP
operating systems, messages may appear, respective of the operating
system, regarding driver and software signatures (Windows logo testing).
Simply continue the installation regardless, and confirm any and all such
prompts by clicking Yes or Continue Installation.
Anytime a new device is installed, Windows checks by default whether the
drivers are Microsoft-certified. Very few drivers are actually certified with
Microsoft, however, because driver certification with Microsoft is quite
consuming. The drivers that you receive directly from devolo have all been
subjected to extensive testing, so you can ignore the Windows warnings with
complete confidence.
Question Why does my Internet connection suddenly disconnect
without me wanting it to, and why is it so slow (slower
than on other analog connections)?
Causes The hardware installation within the computer case has to be clean and
correct. By clean and correct, we mean: few junction boxes, and tightly,
cleanly and correctly connected electrical connections (using screws and
fasteners), etc. Magnetic and electric fields, such as halogen desk lamps
placed on the modem, can cause interference.
For lack of enough available phone jacks, two devices may have to share
the same physical line. To this purpose, multiplexers are installed at the
customer junction line point. Often, these are labeled, for example with
“PCM-2” (for two users). If a multiplexer is in use, fast V.90 connections
are not possible. Instead, the top transfer rate will be 33.6 Kbps. You can
contact your telephone service company for more information and to find
out if a multiplexer is installed on your line. In Germany, business

|Appendix 17
|devolo MicroLink 56k Fun II |
EN
subscribers call Telekom at 0800/3301172, and residential subscribers
call 0800/3302000.
Find out whether any additional services are enabled for the analog
network, such as call charge metering, call waiting, etc. The signals sent
over your line by such services have little effect on voice calls. However,
they act as noise interference on a data line and should be disabled for
the duration of data connections. In apartment buildings especially, many
phone jacks are installed and used on many floors. Often, the
installations of these terminals are parallel, which is a code violation in
Germany. Germany's telephone networking codes require that the house
connection is nonreflecting at a specific impedance. Connecting several
devices having the same impedance in parallel reduces the total
impedance. This should be avoided as much as possible. A clean
technical solution to this is the so-called telephone toggle switches,
which prevent a second phone to listen in on an existing call, or small
branch exchange systems, which usually allow you to make in-house
calls as well.
The fast transfer protocols based on V.90 and 56kflex cannot be compared to
the classic modulation protocols. Unlike, for example, V.34, these protocols
are based on a different technology. In principle, the maximum achievable
speed is determined by the amount of available line bandwidth. This can vary
greatly from one line to the next and therefore, the actual connection speed
can vary significantly.

6 Additional regulations
a) The above conditions define the complete scope of devolo's legal liability.
b) The warranty gives no entitlement to additional claims, such as any refund in full or in part.
Compensation claims, regardless of the legal basis, are excluded. This does not apply if e.g.
injury to persons or damage to private property are specifically covered by the product lia-
bility law, or in cases of intentional act or culpable negligence.
c) Claims for compensation of lost profits, indirect or consequential detriments, are excluded.
d) devolo is not liable for lost data or retrieval of lost data in cases of slight and ordinary ne-
gligence.
e) In the case that the intentional or culpable negligence of devolo employees has caused a
loss of data, devolo will be liable for those costs typical to the recovery of data where pe-
riodic security data back-ups have been made.
f) The warranty is valid only for the first purchaser and is not transferable.
g) The court of jurisdiction is located in Aachen, Germany in the case that the purchaser is a
merchant. If the purchaser does not have a court of jurisdiction in the Federal Republic of
Germany or if he moves his domicile out of Germany after conclusion of the contract, devo-
lo's court of jurisdiction applies. This is also applicable if the purchaser's domicile is not
known at the time of institution of proceedings.
h) The law of the Federal Republic of Germany is applicable. The UN commercial law does not
apply to dealings between devolo and the purchaser.
