[Term] Internet Protocol [Definition] 
Refers to the connection type of a merchant’s point of sale set-up. Examples of IP connections are high-speed Internet connections, T1 lines, cable modems, DSL, etc. In order to be considered an IP merchant, the merchant must only use an IP connection. If an IP merchant’s terminal needs to be reprogrammed, the download must be performed on a dedicated analog phone line, not an IP line.
