IDM-30FN 30chs Telephone Optical Multiplexer transmits up to 30 channels of voice/telephone or data signals over a pair of fibers or one single fiber. It could accommodate more than ten types of plug-in cards including FXO, FXS, 4-wire E&M, 2-wire E&M, V.24, etc. All plug-in replaceable cards could be inserted into or removed from the slots on the main board at will and 8E1 channels are able to provide users with extra 240 channels for 64Kbps data signal transmission, all of which makes IDM-30FN not only very flexible but also supremely expandable.
Features
1. Transmission medium is fiber .
2. Standard 19” 1U housing, easy to install.
3. Modular configuration and 8 E1 channels make it flexible and expandable.
4. The amount of voice channels is variable within 30.
5. DIP switch and LED alarm indication available.
6. Four 10/100Mbps shared Ethernet ports supporting VLAN.
