ABSTRACT:
A host device, a point of deployment (POD), and a method for recognizing an operation mode are disclosed. The host device interfaces with a point of deployment (POD), and checks an operation mode of the POD. The interface unit includes CD1#, CD2#, VS1#, VS2#, VPP1, VPP2, and ISIO16# ports. The controller detects Card Information Structure (CIS) information from the POD if each of the VS1# and VS2# ports is set to ‘Logic Low’, and determines whether the POD supports an Internet Protocol (IP) Card S-Mode on the basis of the detected CIS information.
