Introduction
ISDN-PRI Card
Figure 5-2 shows an application where a user needs less than 23 B channels (say 6 B channels
for video), and some dedicated DS0s (say 12 for LAN-WAN interconnect). In this case, the D
channel, B channels, and the DS0s all run on the same facility from the equipment to the
carrier. Inside the carrier’s facility access point, the D and B channels are extracted from the
facility and sent to the ISDN switch, and the 12 DS0s are extracted from the facility and sent
to the carrier's dedicated DACS network. In this example, 5 timeslots are unused.
