Abstract:
1. A transmission system using a dying gasp, the transmission system being implemented for a communication terminal connected over an Ethernet, comprising: a Switching Mode Power Supply (SMPS) for supplying power to an Ethernet-based lower level system, detecting a state of a power fault, and outputting a dying gasp alarm signal; a Central Processing Unit (CPU) for receiving the dying gasp alarm signal from the SMPS, and generating and transmitting an alarm packet; a Physical layer (PHY) chip for receiving the alarm packet from the CPU, and uplinking the alarm packet so that the alarm packet is transferred to a higher level network; and a Layer-3 (L3) switch for receiving the alarm packet from the PHY chip and determining whether a power fault has occurred in the lower level system.
