Currently, the design of confidential communications multi-user access systems encourages a particular interest of transmission methods, which provide not only an increase of channel capacity, but also improve the security of transmitted signals. Transmission security is one of the important indicators of noise immunity and it determines the ability of a system to resist the actions aimed at detection of a signal and scanning of its parameters.The article proposes a method of forming a group signal based on a plurality of multi-level timer signal designs with their division according to the level. To improve the structural security of information signals of individual channels, the system uses multi-level timer signals, which are then combined into a group signal. In order to reduce the effectiveness of unauthorized access means for the procedure of decoding of an intercepted signal the method of division of timer signal constructions according to the level is used.The purpose of the article is to develop a method of forming a group signal based on a plurality of multi-level timer signal designs with their division according to the level.The proposed method of forming signal designs can be recommended for the construction of confidential multi-user access systems, in which additional measures are taken to protect the information on the first level of the reference model OSI
