ISDN BRI
The ISDN ports are connected to ISDN terminals (Phones PBXs) or an ISDN NT using cables terminated
with RJ-45 connectors. Use straight-though cables to connect to the S/T port of your NT or phones/PBX.
Figure 15. Connecting an ISDN device
The interconnecting cables shall be acceptable for external use
and shall be rated for the proper application with respect to volt-
age, current, anticipated temperature, flammability, and
mechanical serviceability.
When this device is used in North America, it shall be connected
to a Network Termination Device and not connected directly to
an outside POTS line.
