Interrupt

Hello guys, can I monitor interrupt0 of 8051 by any h/w means like by LED or something? I have connected RTC DS12887 IRQ to INT0 however I couldn't see logic 1 on DMM

Ya Westermark without connecting dallas chip 89c51 int0 pin is high
but as soon as I connect IRQ of DS12887 to INT0 of at89c51 the signal goes down (low level) so what does it mean?
