Detailed Product Description
Overview
IDM-300ME provides 2 shared 10/100Mpbs FE interfaces, 6 transparently transmitted E1 interfaces and at most 300 FXO/FXS interfaces with “caller ID display” feature.
IDM-300ME also provides 13 slots, which would be able to accommodate 1 MCU (main control unit), 10 user’s units and 2 power units. All of these units are hot-swappable.
Features
1. Transmission medium is fiber and the optical line rate is 155Mbps.
2. 1 MCU unit and 10 user’s unit, each of which provides 30 channels of 64kbps voice.
3. The capacity of IDM-300ME is 300 channels.
4. Two 10/100Mbps shared FE interfaces with VLAN feature.
5. 6 transparently transmitted E1 interfaces, 4 of which is 75ohm and the other 2 are 120ohm.
6. Rack-mountable 6U frame, easy to install and maintain.
7. 6*E1 transparent transmissions make it very expandable.
8. Dual power supplies to make up a 1+1 redundancy.
