BRI works over the same wiring that is in place for analog
telephone lines. The difference is in the equipment you attach
and signaling used.
ISDN Basic Rate Interface
Physical Appearance
At your site, the ISDN lines will use RJ45 wall jacks and cables,
each of which, in ISDN, make up the S/T interface. RJ45
connectors have 8 pins. See Figure 1 below. The connectors, or
cables, for attaching the NETServer Plus modems to the jacks
installed by your service provider are in the package.
Figure 1. RJ45 Connector and Jack
Your ISDN service provider adds a line card at its end of each
BRI that adapts the line for ISDN.
