XBee ZNet 2.5 (formerly Series 2)

What i meant was....How to use a device as router or end device

suppose i have 15 Xbee modules in my network.
1 as co-ordinator. Now out of other 14 i want 10 to act as end device and rest 4 as router. all of them have firmware version 1241 flashed on them.Now how do i make a device to act as router and other as end device.

I think it will be governed by the sleep mode value i set.
If i set ATSM 0 (sleep mode off) then it will act as router and for ATSM 1 and ATSM 2 as end device.

Comments???
