void Int_timer_tf2 (void) Interrupt 7 using 2{... source lines ...}

There is keywords:
Interrupt xDefines the interrupt number. This number tells compiler which vector address of you want. See also the manual "Cx51 Compiler User ' s guide-chapter 3 Language extensions-function declarations-interrupt functi Ons "on p. 125. Look at the table "Interrupt number" to "Adress"!

using xdefines the desired register bank access for the interrupt function.

in the example mentioned above, the function INT_TIMER_TF2 ()Would be called if a TF2 event occurs, because the interrupt vector address is 0x003b. This function is use of the Register Bank 2 (registers in Addr 0x10 to 0x17).

If you want to get other interrupt vectors addresses than the standard one described in the manual you had to define Y Our own interrupt vector addresses with theIntvector and INTERVAL control directives. Please read the manual.
