In telecommunication network transmission media is very precious. CDMA network elements (e.g. MSC/VLR, SMSC (Short Message Service), HLR and SCP are connected via dedicate E1 (PCM) links for signaling (CCS7), which is very vulnerable or low redundancy. The CDMA refers to such a technology that the transmitting end modulates the signals that it sends using mutually different and (quasi) orthogonal pseudo-random address codes, and the receiving end detects the corresponding signals by demodulating the mixed signals using the same pseudo-random address codes.
