— In this paper we suggest a new presentation and overview of telecommunication networks or GSM network. It is a great opportunity for me to manipulate and do to many actions inside the GSM network that equip with hundred electronic systems like: Mobile Station (MS), Base Station Controller (BSC), and Base Transceiver Station (BTS), Mobile Switching Center (MSC), Transcoder Rate Adaptation Unit (TRAU),Home location Register (HLR), Service Control Point SCP, Service GPRS Support Node (SGSN), Gateway GPRS support Node( GGSN) , Add Drop Multiplexer( ADM ) for SDH transmission. Element Network based on Information theory/Signal processing (ENIS) used in cascade configuration is the key to understand more about methods, architectures, algorithms used in information theory, signal processing and protocols even if the network is complex. The important thing is whatever the equipment in network it can be presented with one or two ENIS, with the specific ENIS we can learn more about many issues hidden for example: source coding/decoding, channel coding/decoding, interleaving /de interleaving, encryption/decryption, modulation /demodulation. But in practice protocols of communication is often apply for trouble shooting and control.
