IDM-ENT448 is a multiservice multiplexer. It transmits 8 channels of telephone (FXO/FXS), 4 E1s and 4 FE signals over a pair of fiber (or one single fiber).
Features
1. The transmission medium is fiber.
2. 4 E1 transparent transmission channels, 4 Ethernet channels and up to 8 telephone channels.
3. Fixed configuration, not modular, makes it very cost-effective.
4. The amount of FXO/FXS ports is variable within 8.
5. Standard 19” 1U housing, easy to install.
6. LED alarm indication.
7. 4 10/100M Ethernet ports supporting VLAN.
8. 4 E1 transparent transmissions make it very expandable.
9.“Caller ID display” feature supported.
