multiple xbees sending to 1 coordinator

hi, i need to configurate 15 xbees talking to 1 coordinator, i assume tthe 15 can tell about their status with the sleep mode, and the coordinator can ask about it, say each 10 seconds. I'm not sure about this, but there's no documentation online about this, but in the other hand, nowhere says the contrary. Am I thinking on the right proccess? I need some advice. TIA!
