Troubleshooting ISDN-BRI/ASAI problems can be a complex and involved
procedure. The reason for this is that ISDN-BRI devices communicate with the
SPE over the Packet Bus, as opposed to the TDM Bus. Therefore, it is possible
for failures of other Packet Bus-related system components to cause problems
with ISDN-BRI devices.
