After that, the DSLAM switches the data over an ATM network to an aggregation router, a layer 3 device where the subscriber's IP connection then expires.
A neural signal is another way of characterizing the electrochemical message that neurons send to each other. When a neuron receives sufficient stimulation in the form of EPSPs, voltage-gated ion channels open, and a signal is sent down the axon to the axon terminal. That is the electrical part of the message.
