1. Overview
1.1. Introduction
RC802/804/806-30B-FV35 series modular 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.
RC802/804/806-30B-FV35 is modular type device and can be installed in our
company’s RC002-16, RC002-4 and RC001-1 chassis. It supports network management
function based on SNMP protocol, and it can be deployed at the local site to realize the
remote management.
1.2. Main Features
z
Provide a V.35 synchronized data DCE interface complied with ITU standard.
z
Provide a dual- fiber or a single fiber dual-wavelength fiber interface.
z
Complies with G.704 frame definition, realize bandwidth control on V.35 interface
z
Whole fiber line alarm and internal E1 detection alarm, and provides local and remote
alarm indication
z
Provide local and remote loop-back test function to monitor line and help to deploy and
maintain device.
z
Support internal E1 data channel’s fractional /unframed (transparent) transfer mode. It
can distribute timeslot freely in fractional mode.
z
Provides three clock mode: master clock(internal clock),slave clock(follow fiber line
clock),V.35 terminal clock( follow V.35 interface clock).
z
When use fractional mode in a pair, the remote timeslot can follow local timeslot’s
configuration.
z
Internal error code test unit can make line detection and line test with several kinds of
loop-back type.
z
In fractional mode PCM30/PCM31 mode are optional and CRC4 verification function is
auto-negotiation.
z
Provide phase adjustment function of V.35 receiving data.
z
Provide Fault pass function to transfer alarm of data line to V.35 interface, so that to
judge E1 signal errors through router.
z
Very large scale ASIC chips, low consumption; four level PCB design, high reliability.
