PDH-SDH RRE “Rissa”

RRE “Rissa”

The description of system

The ruler of radio-relay stations “Rissa" is intended for the organization wireless, zones networks of transfer of figures and the information.

Use of such systems in places where making of cable systems is connected with technological and material difficulties and where the factor of time is of great importance is especially actual. The given equipment is executed on modern element base and according to the newest development in the field of wireless transfer of the information. The equipment possesses the following and features:

• In the big information capacity;
• High quality of reception and transfer of the information;
• Multifunctionality;
• Ecological safety;
• High reliability;
• Power profitability;
• Small time of deployment;
• Absence of necessity for special constructions;
• Compatibility with cable information systems;
• High noise immunity.

The given systems can be applied to the decision of such problems as:

• The organization of digital information networks, as the general(common), and special purpose(assignment,destination);
• The organization of networks of data transmission of local computer networks, telemetering and security systems;
• Expansion regional telephone and computer networks;
• Distribution of television programs to the analog and digital form.
