IDM GP2400
The IDM GP2400-8E1-30 Gigabit Network Optical Terminal features a 2.5G optical interface, providing up to 30 voice access channels, 8 groups of E1, 2 physically isolated wire-speed 1000M Ethernet ports, and 4 physically isolated wire-speed 100M Ethernet ports over fiber, with a standard SNMP network management interface.
I. Overview
The IDM GP2400-8E1-30 Ultra-Broadband Integrated Service Fiber Multiplexer utilizes 2.5G fiber transmission bandwidth (G.703 standard) with PCM30/31 framing, providing dual-fiber backup. It directly offers telephone service interfaces (up to 30 channels of FXO, FXS, or Magneto), 4 groups of physically isolated wire-speed 100M Ethernet (400M total), 2 groups of physically isolated wire-speed 1000M Ethernet (2000M total), E1 (1-8 E1 channels), HDMI HD video transmission, and various other user interfaces. The device is easy to install and suitable for various application environments.
It provides dual-fiber backup and can be combined with other devices to form multiple physically isolated Ethernet chain networks Telephone Optical Terminal, ring networks Telephone Optical Terminal, and point-to-multipoint star networks Telephone Optical Terminal.
