He is referring to the last byte (last 2 hex digits) of an NSAP address.
The more or less defunct LANE technology used the selector byte to
differentiate among multiple services on the same switch.

Not sure what it is used for otherwise - most examples have it set to
00.

I am looking at the ATM cell structure. I do not see a selector byte.
Can
you elaborate?

Hello,

Can someone tell me what is the purpose of the selector byte in ATM?
