We strongly recommend that you read this user manual before using LineCrypt.
Deutsche Telekom cannot be held liable for any possible damage caused to
the device or other facilities arising from the failure to follow the instructions in
this manual.
Overview of pictorial symbols
Safety symbol to warn against danger for people and property is identified with
a triangular warning sign.
Important messages for data security are identified with the hand icon.
Important messages for operation of the LineCrypt DSL are identified with the
bulb icon.
Safety notes
Do not open the LineCrypt. By opening the four screws on the base of the
•
housing you may endanger the user and any warranty claim will be waived.
Allow no liquids to seep into the LineCrypt.
•
Assemble the device as described in the section “Assembly”.
•
Do not plug in or detach any connections to the LineCrypt during a thunder-
•
storm.
The LineCrypt is only intended for use in dry indoor areas.
•
Lay the cables in such a way that they cannot be stood on or tripped over by
•
anyone.
Before any maintenance work on the LineCrypt pull out the mains plug.
•

General
Only terminal equipment that delivers SELV voltage and/or corresponds
•
with ETS 300 047 may be connected to the LineCrypt DSL.
Connect the device to a freely accessible earthed socket so that you can pull
•
out the mains plug without delay when required.
Power failure
The configuration remains unchanged in case of a power failure.
The LineCrypt DSL is not provided with an emergency operation. In the event of
a power failure you cannot communicate via the LineCrypt DSL.

Function Overview
Function Overview
The T-TeleSec LineCrypt DSL provides protected data transfer via networks
that uses the PPPoE protocol.
The LineCrypt DSL acts as a link between a protected internal network and an
unprotected external network. The LineCrypt DSL is based on IP communication. That means: All other protocols, IPX for example, are not forwarded between internal and external sides by LineCrypt DSL.
LineCrypt DSL transfers the encrypted data through an IP Tunnel. In this way,
two or more LineCrypt in an unprotected network allow a protected Virtual Private Network (VPN) to be set up.
The LineCrypt DSL can set up IP tunnels to LineCrypt DSL, L and SOHO. If the
IP addresses are assigned dynamically for the connection configuration, two LineCrypt DSL require a directory service, which can be provided, for example,
by a LineCrypt L. The option of unencrypted connections with other IP equipment can also be configured.

Plug the connection to your internal network into the 10BaseT internal socket.
The connection to InternetGateway is made via the 10BaseT
external socket. As the pin assignment of the Ethernet socket corresponds to
the pin assignment of a network card, the following applies for the cable to be
used:
Use a crossed cable when connecting to a network card (e.g. PC).

Installation place
Place or hang the LineCrypt DSL in a suitable place. For wall mounting, please
use the enclosed drilling template and mount the LineCrypt with the sockets on
the underside. The installation place should be dry and free from dust. The LineCrypt is designed for an environmental temperature range of +41°F to
+104°F. Therefore, do not expose the LineCrypt in direct sunlight and be sure
that there is sufficient ventilation.

Start-Up
Start-Up
After the appropriate installation, connect the LineCrypt DSL with the mains cable plug to a earthed socket. The LineCrypt DSL perform a self-test. After 10 to
15 seconds it will start up normal operation.
It is not possible to set up connections with other equipment in the delivery
status. To be able to configure encrypted connections with other LineCrypt
equipment or unencrypted connections with other Ethernet devices, a corresponding configuration of the LineCrypt DSL is required. Use the provided PC
program “lcc” to configure the LineCrypt.
Via the local management you also have the option of configuring authorized
system administrators for remote maintenance.
CD/configuration software.
The settled CD contains the configuration software for the LineCrypt DSL, the
operating instructions for the software as well as further documents. Latest information can be found in the file “readme.txt”

LED on the top side
On the top side of the LineCrypt there are three multi-colored light-emitting diodes (LED), which are labeled, On, I and II.
The On LED signals the ready status of the equipment. The I LED serves to display the data traffic on the network. The II LED serves to display key exchanges
and faults in the equipment management.

(also called datagrams) are transported by the IP as independent data
packets (even in the case of identical senders and receivers). IP
guarantees neither observance of a particular sequence nor delivery to
the receiver (that is, datagrams can be lost on account of network
overload, for example). There are no receive acknowledgements on the IP
layer.
IP Network
Network based on the Internet Protocol. Every device in the network is
addressed through an IP number.
IP Tunnel
A connection between two subnetworks, which conceals the precise
addresses of the communication partners. At the start of the tunnel, all
data packets receive an additional header that refers to the tunnel end.
Here the external frame is removed and the original data packet is
forwarded to its actual receiver.
