Overview:

The IDM-30F series integrated service multiplexer adopts a 19-inch 1U standard chassis with a transmission rate of 155M. It supports 4 shared line-rate 100M Ethernet channels with VLAN partitioning and 8 groups of transparent E1 channels, while allowing flexible configuration of 20+ types of service interface cards.

The IDM-30FN2 provides 2 groups of optical interfaces, suitable for point-to-point and chain network topologies. With a single fiber optic line resource, it can provide voice and data services for 8 user nodes. Each node can be configured with 30 channels of 64K services, deployed in bus or point-to-point topology. All nodes on the entire fiber link share the line-rate 100M Ethernet interface.

Product Features:

• Supports multiple voice, data, and video service access;
• RJ45 user interface design for easy installation and maintenance;
• Nyquist frequency signal system sampling;
• Powerful audible and visual alarm functions;
• Comprehensive monitoring functions for timely line status diagnosis;
• Provides 4 groups of shared line-rate 100M Ethernet interfaces and 8 groups of transparent E1 interfaces;
• Supports access of 30 channels of 64K or N×64K voice, data, and video user interfaces.
