IDM STM1

Overview:

The IDM GE/STM1 is an intelligent aggregation bridge developed based on customers' high-capacity Ethernet private line access requirements. It enables aggregation of 63 groups of E1 to Gigabit Ethernet and can be directly interconnected with SDH transmission equipment. The 1 to 63 channels can be arbitrarily allocated according to different bandwidth requirements, transparently carrying Ethernet data with the channel as the link unit. At the same time, the application of this product reduces the cost of network construction and maintenance for operators, enhances the response capability of private networks, ensures end-to-end analysis capability for customers, and enables customers to monitor the entire network.

Features:

• Provides 2 STM-1 interfaces, operating in SDH ring networks and chain networks, with 1+1 protection support;
• Provides 2 Gigabit Ethernet interfaces (1 optical + 1 electrical);
• Automatically allocates bandwidth within the channel based on the number of E1 lines, supporting asymmetric transmission of E1 lines;
• Strong compatibility, supporting mixed networking applications with single/multiple E1 bridges from different manufacturers as remote devices;
• Adopts standard 19-inch 1U chassis with dual power supply redundancy design; easy to maintain, supporting unified network management across the entire network.
