Local Extended Area Service (EAS) Traffic “Local” traffic refers to calls that originate and terminate within the same calling area and do not incur a toll charge.

“Extended Area Service” indicates that end users in a specified geographic area have paid a higher flat monthly fee to call within a larger area rather than paying a lower flat monthly fee for a smaller area and incurring toll charges to the locations which would have been in the EAS.

Usually, this service is provided over the SS7 signaling protocol.
