This device provides 1-4* E1 interface, standard 2-wire telephone as engineering order-wire (optional).
This device provides 1-4* E1 interface, Standard 2-wire telephone as engineering order-wire (optional). It is very flexible. It has an alarm function. The work is reliable, stable, and low power consumption, high integration, small size.
● Based on self-copyright IC
● Modular wide dynamic optical detector
● Uses standard 2 wire telephone(non-telephone handles) set as engineering order-wire hotline(optional)
● E1 interface complies with G.703, adopts digital clock recovery and smooth phase-lock technology
● When the optical signal is lost, it can detect the remote device is powered off or the fiber is disconnected and indicates an alarm by LED
● The local device can view the remote device’s working condition
● Provide command the remote interface Loop Back, ease line maintenance
● The transmission distance is up to 2-120Km without interruption
● AC 220V, DC-48V, DC+24V can be optional
● DC-48V/DC+24V power supply with automatic polarity detection function, when installed without distinction between positive and negative
