BRI
A straight S-Bus cable with RJ-45 plugs is used to connect an ISDN NT or TE to the SmartNode or
interface card. See Figure 7 (telephone connection) and Figure 8 (NT connection) for the appropriate
information. For BRI ports with configurable pin outs ensure that the appropriate mode (NET or
USR) is configured.
Warning:
Network hazardous voltages are present in the BRI cables. If you detach the cable, detach
the end away from the SmartNode or interface card first to avoid possible electric shock. Network
hazardous voltages may be present on the device in the area of the BRI port, regardless of when
power is turned OFF.
Caution:
To prevent damage to the system, make certain you connect the BRI cable to the BRI Port
only and not to any other RJ-45 Socket.
