IDM-8ENT transmits at most 8 channels of telephone (FXO/FXS), 8 E1 and 8 FE signals over a pair of fiber (or one single fiber).IDM-8ENT is a fixed configuration, with FXO/FXS modules soldered to the main board, this model is more cost-effective than modular ones and also has a more stable performance.
Features
1. Transmission medium is fiber.
2. 8 Ethernet channels, 8 E1 transparent transmission channels, 8 telephone channels and 2 RS232 (V.24) channels.
3. Standard 19¡± 1U housing, easy to install.
4. Fixed configuration, not modular, cost-effective.
5. The amount of FXO/FXS ports is variable within 8.
6. LED alarm indication.
7. 8 E1 transparent transmissions make it very expandable.
8.¡°Caller ID display¡± feature supported.
