TB3 - Global after T=15 in TDi–1
For T=1 protocol the first TB
i encodes Block Waiting Integer and Character Waiting Integer. The high nibble encodes BWI. The low nibble encodes CWI.
For T=15 protocol TB
i the coding is defined in the document
ETSI TS 102 221 V10.0.0 (2011-12) chapter "6.3.3 Global Interface byte"

T=1 protocol
The list above is not really informative since both BWI and CWI are coded in the same byte.

T=15 protocol
I my list I have only 5 cards with a TB
3 for T=15. They all have the value TB
3 = 0xA0 for "UICC-CLF interface supported as defined in TS 102 613".
