iDen Network Problem!

Hello, I have some experience over it. iDEN is called Integrated Dispatch Enhanced network. It is based on TDMA technology which is very useful for communication. iDEN is a TDMA based digital wireless designed to work for special frequencies originally designated for analog Specialized Mobile Radio networks. iDEN is invented by Motorola. Motorala remains the primary manufacturer of iDEN devices. Due to sending, this cause has received a request to route the call through a particular transit network which it does not recognize. Due to equipment sending this cause does not recognize the transit network either because the transit network does not exist.The interconnect side of the iDEN network uses GSM signalling for call set-up and mobility management. I hope i have answered your query well.
