I. Overview

The IDM MINICP equipment is a new-generation multi-service optical transmission/access device based on SDH technology, launched by Beijing Raytrans Digital Technology Co., Ltd. It integrates three technologies — SDH transmission, PBX switching, and all-optical Ethernet switching — into one platform, and incorporates audio/video command & dispatch functions. It can be widely applied in private networks such as public security, electric power, railway, and mining, as well as public networks operated by China Mobile, China Unicom, and China Telecom.

The MINICP equipment adopts a 19-inch, 3U, plug-in card chassis structure. Depending on actual requirements, different quantities and types of tributary service boards can be configured to provide multi-service access. It provides uplink STM-1/STM-4 optical interfaces and supports 1+1 optical board protection. The optical access board types include: STM-1 access boards and STM-4 aggregation boards. Downlink services include Gigabit Ethernet, Fast Ethernet, telephone, data, and various 64K service access.

The MINICP equipment is primarily used for service access, transmission, and aggregation at the access layer of data communication networks. It features complete synchronization and timing functions, a powerful non-blocking cross-connect matrix at both VC12 and 64K levels, and aggregation capabilities for voice, IP, and V24 Ethernet services. By configuring the audio/video command & dispatch module and leveraging the multiple transmission and access methods of MINICP, an audio/video command & dispatch system can be established, suitable for emergency command and other scenarios, meeting the requirements of network edge users for diverse access technologies, diverse transmission services, and diverse network topologies.

The network management platform can adopt the Netguard network management system from Beijing Raytrans Digital Technology Co., Ltd., providing powerful server/client-based, hierarchical management capabilities, including configuration management, fault management, performance management, permission management, and log management.

IV. Typical Applications of the Equipment

When the IDM-MINICP equipment forms point-to-point connections with the MSAP155-24, MSTP155-24, and MSTP155-16 equipment, it can use either single-fiber connections or dual-fiber connections to implement 1+1 channel line protection. The equipment transmits services over optical fiber, facilitating user access to nearby fiber-optic networks. Two units connected via a pair of optical fibers can provide E1 services, Ethernet services, V.35 data services, and PCM voice services, enabling point-to-point service aggregation.

Each regular board in the IDM-MINICP centralized equipment can form two ring networks or chain networks, and can be used in conjunction with MSAP155-24 equipment as required to implement complex star or ring network topologies.

A ring network can be formed using one IDM-MINICP centralized equipment unit with multiple MSAP155-24 optical transmission equipment units. The 1+1 channel protection mechanism ensures the real-time and accurate transmission of all data and voice services within the ring network. The optical ports of the IDM MSAP155-24 can be readily connected to nearby communication networks (such as mobile base station SDH networks, China Netcom/China Telecom SDH edge networks, and military SDH transmission networks), enabling it to support various communication services during regional emergency situations.
