Connecting cables
Installing the IC-4BRV-8V interface card cables
A straight-through S-Bus cable terminated with RJ-45 plugs is used to connect an ISDN NT or TE to the
interface card ports (see
table 38 for port pin-out listing). If you are connecting a BRI to an ISDN telephone,
see figure 75 ; or see figure 76 on page 119 if you are connecting a BRI to an NT. For BRI ports with config-
urable pin-outs ensure that the appropriate mode (NET or USR) is configured.
Note
Pins not listed are not used.
The Interconnecting cables shall be acceptable for external use and shall be
rated for the proper application with respect to voltage, current, anticipated
temperature, flammability, and mechanical serviceability

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.
