Installation and Commissioning
Network Provider
Connecting the Ethernet Port with the Internet/LAN
downloads), we recommend upgrading to a data transmission rate of
100 Mbps. For this purpose, replace not only all of the active network compo-
nents (e. g. switch and router), but also all of the passive network compo-
nents (e. g. cables and wall sockets). For a reliable support of 100 Mbps, you
need cables and wall sockets of at least Category 5 (CAT5).
– To use DiffServ to prioritise speech packets: DiffServ support of all active network
components 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 configuration manager of the PBX under Overviews > Ports.
• Patch cable
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. In addition, note the PBX factory
settings for the Ethernet configuration (see chapter Commissioning >
Opening the Configuration Manager of the PBX via PC in the Same Network).
1. Insert one end of the patch cable into the output socket on the router or into an
existing network outlet.
Note: To connect the router to the network provider, read the documentation
provided by the network provider, as well as the documentation of the router.
2. Insert the other end of the patch cable into the Ethernet socket of the PBX.
3. Use a cable tie to attach the cable to the straps for strain relief at the bottom of the
casing.

Caution: Opening a port on the NAT router is a security risk.
• Take additional protection measures.
