1.1 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.
1.2 Characteristics
Dithering tolerance and dithering transmission characteristic of E1
channel have high performance, which is superior to industry
standard
Support CAS and CCS mode
Support CRC-4 verifying
Follow remote device settings can be set
Data rate of E1 interface N×64kbps(N=1~32)is adjustable
Support autosense V.35 phase
