The document discusses the Answer to Reset (ATR) from a UICC card during initialization. The ATR provides information about the card's capabilities and requirements for communication. It consists of start characters followed by optional interface and historical characters, and a check character. The ATR puts the card in specific or negotiable mode depending on the presence of an interface character TA2. It also discusses the optional PPS procedure for negotiating transmission speeds between the mobile equipment and UICC card.
