BRI
A straight-through S-Bus cable with RJ-45 plugs is used to connect an ISDN NT or TE to the SmartNode or
interface card. See
figure 92
(telephone connection) and
figure 93
on page 147 (NT connection) for the appro-
priate information. For BRI ports with configurable pin outs ensure that the appropriate mode (NET or USR)
is configured.

Hazardous network 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.
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.
