Forget requirements like "real-time" dialing. And, remember that the calls of the most advanced POTS of digital ISDN is delayed a several seconds after dialing, because ISDN has a wonderful feature of optional and variable length subaddresses. Remember also that the delay occurs for all the calls even though virtually no one is using the subaddresses.
