How to Share Time Slots of Redundant Device in Exchanger

摘要

The present invention relates to a method for sharing a time slot of a duplicated device in an all-electronic exchange, wherein after requesting a time slot to be allocated by a telephony processor, if the device can not allocate a desired time slot in the telephony processor, If a time slot can be allocated, the device changes its time slot to the requested time slot. Since the device sends a response to the changed time slot confirmation by the changed time slot confirmation request from the device, the changed time slot between the device and the telephony processor If the device is configured to be redundant, the device in the standby state requests time slot information from the active device to share the time slot with the telephony device, and in the active device, When the device in the active state is switched, the device in the standby state becomes active, and normal communication with the telephony device is performed, thereby increasing the stability of the system operation and providing a high-quality service. There is an effect that can be.
