• Unscreened; however: screened for unfavourable conditions, for example, near a strong
transmitter or an electrical power line
Analogue: Prevent interferences. Avoid laying long lengths of parallel lines, especially next
to the mains. Twist the pairs.
Accessories and service parts can be bought at specialised stores.

Ethernet Port

Requirements:
• For Internet access: Broadband Internet connection (e. g. DSL router, TV cable router)
•
Existing network (LAN) or single switch (for VoIP terminals) with a data transmission rate
of 100 Mbit/s
Note: For VoIP data communication in combination with the transmission of additional
data (e. g. downloads), we recommend a data transmission rate of 100 Mbps. For a
reliable support of 100 Mbps, you need cables and wall sockets of at least Category 5
(CAT 5).
Note: When using a switch with PoE function, a separate power supply (e. g. via a
power plug) is not required for connected VoIP telephones, always provided they
support PoE.
• For the use of DiffServ for prioritising language packages: DiffServ support of all
active network components is available and enabled.
• NAT traversal should be carried out either by the PBX or by a well-functioning SIP-
aware router.
Note: If the router is not SIP aware, several of the ports on the router necessary for
VoIP data communication must be enabled (RTP port and SIP UDP ports) (port
forwarding). A list of the ports used in the PBX can be found in the web interface of the
PBX under Administration > Network > Ports.
Caution: Opening a port on the NAT router is a security risk.
• Take additional protection measures.
Important: If you want to integrate the PBX into an existing network, contact the
responsible system administrator. Making changes to an existing network can cause
considerable malfunctions.
