For Trunk Mode: The BRI circuit can be plugged directly into the NT1 Termination. Use an
RJ45 patch cable.
For S-Bus Mode: The ISDN terminals can be plugged directly into the RJ45 connector on
the BRI card. If more than one terminal is connected run a 2 pair cable to an RJ45 socket then
daisy-chain the connection to the additional ISDN terminals. For pin-out information for S-
Bus connections, refer to BRI (2/4/8BRIU) Interface PCB (Figure 2-15) (page 2-34).
Repeat for each BRI circuit.
Note that the polarity of the RJ45 connector is set by SW102 to SW802 on the BRI PCB
