IDM-8ENT
8channels telephone 8E1 8Ethernet PCM multiplexer IDM-8ENT
IDM-8ENT transmits at most 8channels of telephone (FXO/FXS), 8E1 and 8FE 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
l Transmission medium is fiber.
l 8Ethernet channels, 8E1 transparent transmission channels, 8telephone channels and 2 RS232 (V.24) channels.
l Standard 19” 1U housing, easy to install Fixed configuration, not modular, cost-effective.
l The amount of FXO/FXS ports is variable within 8.
l LED alarm indication.
l 8E1 transparent transmissions make it very expandable.
l “Caller ID display” feature supported.
l DC-48V or AC220V for power supply. Dual power supplies available too.
