2. Main Characteristics
a) Based on the state-art-of VLSI technology, high density integration,single PCB design, stable and reliable
performance, low power consumption;
b) The transmission distance is more than 25 kilometers without relay;Provide 10/100Base_T interface with bit rate of 100M.
c) When the device loses optical connection or runs out of sync,AIS alarms will be sent to all channels.
The alarms can be sent to the local or remote side at options,the alarming sound can be shielded,so
does the alarms of losing E1 channels.Instead,error indications will be provided.When the device loses
optical connection or runs out of sync,no other output comes from 2MB/S asynchronous data sampling
channels except output of AIS.
d) E1 interface complies with ITU-T G.703 recommendation, and all-digital timing and smooth PLL technology is
adopted.
e) LED indicates the alarms of local and remote side.
f) Optional power supply: 220V AC, -48V DC
