Touch Dial is a feature that will automatically cause the link to be dialed and connected when there is terminal traffic, and disconnect when there is no terminal traffic. The disconnect timer can be set for a value of 1 to 99 minutes. One Touch Dial is a high performance, low cost way to use ISDN dial up for users with low traffic volume from a remote office to the host computer. With One Touch Dial , charges accrue only when someone is using the link, not all day long. And, ISDN connects and disconnects almost instantly.
Connection takes less than half a second, disconnection takes just a few milliseconds.
Set the ISDN TA to synchronous, auto answer. Set the SPL to synchronous leased line operation. Switch position 2 of the 6 position DIP switch must be up, the other 5 positions down. Configure register S0 with the phone number that is to be dialed. Configure for synchronous operation.
