Ethernet:
To connect the system to a LAN, use the Ethernet cable provided by TANDBERG (or a
standard Ethernet cable). If no LAN is available and the codec is connected directly to a
computer, use a crossover cable.
The crossover cable specification is:
If such a connection is needed, the system and the PC must use ‘static’ TCP/IP settings
because no DHCP server is controlling the small “LAN”, which has been created between the
computer and the system. When configuring a back-to-back connection between the PC and
the system, make sure both static IP addresses exist on the same subnet.
BRI ISDN Interface:
To connect the system to BRI, use the ISDN cable provided by TANDBERG (or a standard
BRI cable).
