Information Technology: Minicom DX-series Telecommunications systems

2021: MiniCom DX-500

According to information for April 2021, the MiniCom DX-500 telecommunications system is a single digital platform for the modernization of communication networks of large enterprises and departments, which is able to optimally fit into almost any corporate communication system.

Appointment:

• For connection with communication networks of other departments;
• To access public networks;
• For operation in digital networks with service integration (ISDN);
• In manual maintenance operator subsystems;
• In dispatch centers;
• In information and passenger centres;
• To create a DECT microcell communication system;
• For interfacing with trunking and satellite communication systems;
• For multiplexing and transmission of up to 4 (up to 12) digital streams E1 by one (over two) optical fibers and semi-permanent switching of individual CSCs and providing data transmission.

Thanks to the support of common digital trunk protocols (DLPs) widely used in the Russian Federation's Interconnecting Communication Network (SCN), the MiniCom DX-500 system can be used as a PBX included in the OGSTFS (national automated telephone system) as a substation. The connection to the GATS, which allocates part of its capacity at the trunk level, is carried out at a primary rate of 2048 kBit/s, which provides 30 B-channels of 64 kBit/s for information transmission and one D-channel of 64 kBit/s for signaling. Interaction with SCS is organized using standard signaling 2VSK (R 1.5), SSN No. 7. MiniCom DX-500 can interact with rural PBXs via two-way SL with two or one FRS. The response to the request of the ANI equipment, implemented in the standard way, makes it possible to include the MiniCom DX-500 in the automatic long-distance communication network as a terminal.
