Description
FE1/V.35 interface converter is designed based on an ASIC chip. The chip adopts special patent technology of reduced dithering, digital phase locked and distill clock, E1 anti-jamming, etc. The inner software and hardware are all modularity, integrating coding, decoding, message insertion and alarm, and make the circuit simple so as to improve the reliability of the device. FE1/V.35 interface converter convert V.35 to E1, and V.35 interface works at DCE mode.
Characteristics
1) Dithering tolerance and dithering transmission characteristic of E1 channel have high performance, which is superior to industry standard
2) Support CAS and CCS mode
3) Support CRC-4 verifying
4) Follow remote device settings can be set
5) Data rate of E1 interface N×64kbps(N=1~32)is adjustable
6) Support autosense V.35 phase
7) Three clock modes are selectable
8) The circuit is designed simply, the device works steadily

Power Supply
AC socket: AC 220V input.
DC socket:
If the power supply is +48V, connect the device + pole with power +48V pole, the device – pole with power GND. +24V power supply must be used with DC+24V model device:
If the power supply is -48V, connect the device + pole with power GND pole, the device – pole with power -48V:
NOTE:
Please check the power polarity carefully, and connect after everything is confirmed. Otherwise the equipment may be caused the forever damages and we won’t take any responsibility because of this!
