Network

Ethernet:
1 x Ethernet (RJ-45 Jack) LAN interface (10/100 Mb) up to 768kbps

To connect the system to a LAN, use the Ethernet cable provided by TANDBERG (or a standard
Ethernet cable).

The cable specification is:

1 ------------ 1
2 ------------ 2
3 ------------ 3
6 ------------ 6

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.

ISDN BRI Interface:
ISDN I.420 (RJ-45 Jack) Basic Rate Interface S/T (2B+D), 128 kbps per ISDN I/F
