Cable Specifications
Warning:
The products are not designed to directly connect to cables that are routed external to a
building.
The RJ45 ports on the units (i.e. ISDN ports and LAN ports) are connected to other devices using standard
category 5 UTP patch cables. These may be supplied with the units but are also commercially available
from numerous retail outlets.
