Chapter 1. RC802-30B-FV35 Introduction
RC802-30B-FV35 series modular N*64kbps V.35 interface fiber optic modems are devices that
are deployed to transmit V.35 signals on fiber optics. They are widely used equipment in
constructing Wide Area Networks, and provide solutions for connecting Routers distantly.
RC802-30B-FV35 supports remote management function, and it can be deployed at the local site
to realize the remote management.
1.1 Description
● Complies with G.704 frame definition，realize bandwidth control on V.35 interface
● Provides three clock mode: master clock、slave clock、V.35 terminal clock
● Fault pass function: transfer alarms of receiving and transmitting E1 side to DCD、CTS
signal of V.35 interface
● Optional reciprocal relations between data and clock of transmitting and receiving at V.35
interface are provided to conform to different branded routers.
● Transparent E1: data rate is 2048Kbps on V.35 interface
● Fractional E1: data rate can be configured N×64Kbps（N=1~31）
● When the devices work in pair by fractional E1 mode，they enable remote loop-back on E1
channel
● When the devices work in pair by fractional E1 mode，the bandwidth of remote site will
follow local site automatically
