FRITZ! – 6 FRITZ!data 41
You do not need a user name or password to connect to
the AVM Data Call Center. On other servers, however,
this information may be required since access is often
restricted to certain users (see the section “Access Pro-
tection” from page 43)
4. Select the transmission protocol. This selection should
be the same as the protocol used at the remote site.
The AVM Data Call Center uses the IDtrans protocol.
In order to set up a connection to a remote computer
with FRITZ!data, the same transfer protocol must be se-
lected on both computers.
5. For the IDtrans protocol, two more options can be acti-
vated: 2-channel transfer and data compression.
If you activate the “2-channel transfer” option, both
Bchannels of your ISDN line are used for file transfer.
This doubles the data transfer rate to 128 kbit/s.
When using 2-channel transfer, please remember that
your ISDN provider charges you for each B-channel
connection.
You may also select the internal data compression option
to accelerate data transfer. The data is then automatically
compressed for transmission over the ISDN connection.
Data compression is only advantageous if the files being
transferred have not already been compressed using ar-
chive utilities. The option is recommended for highly com-
pressible data such as image and text files.
6. If you activate the option “CAPI SoftCompression
X.75/V.42bis” in addition to FRITZ!data’s own compres-
sion function, data transfer rates can be increased signifi-
cantly, depending on the data type. The remote system
must also support V.42 data compression.
7. Click “OK” to confirm these entries and begin dialing.
When the connection has been established, the files and
folders of the AVM Data Call Center appear in the right half of
the window. The title bar of the window which has the focus
is highlighted.
