Once the Teleset has been completely programmed, it is possible for the serving switch to change the Teleset’s programming. This feature is called Auto-Parameter Downloading. Like all features, there are pluses and minuses to it. On the plus side, the Teleset will always be in agreement with the switch. On the minus side, the switch can erase Speed Dial keys, remapped keys, etc. without the user’s knowledge.
