IDM-30EN transmits up to 30 channels of voice, 2 channels of Ethernet and 4 channels of E1 over a pair of fiber (or one single fiber).With all FXO/FXS modules soldered to the main board, this model is more cost-effective than modular ones and also has a more stable performance. Besides, 4 E1 channels are able to provide users with extra 120 channels for 64Kbps voice/data signal transmission, which makes IDM-30EN also very expandable.

  2. Standard 19” 1U housing, easy to install.
  3. Fixed configuration, not modular, makes it very cost-effective.
  4. The amount of voice channels is variable within 30.
  5. DIP switch and LED alarm indication available.
  6. Two 10/100Mbps shared Ethernet ports supporting VLAN.
  7. 4 E1 transparent transmissions make it very expandable.
