- Timeout-counter is not in the NT1 equip. ISDN exchange can detect which
- type equipments are attached to customer ISDN busline, and ISDN exchange
- subsystem will answer as "There is no equipment you can talk with....."
- IN THE CASE OF caller is ordinal analog telephone system.
-
- If caller uses ISDN, caller will get various ISDN indication information
- from remote side; "Callee refuses you", "There is no equip for you", or
- "Something wrong in net" answered by ISDN exchange....
