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

Three clock modes are selectable

The circuit is designed simply, the device works steadily
