2. Overview
2.1. Introduction
RC904-V35FE1-BL V.35 to E1 interface module converter extends
transmission distance of V35 data by utilizing long haul transmission of E1 line.
They provide a solution for remote connection of routers, and are very common
interface converter devices in WAN organizing.
RC904-V35FE1 provides one V.35 interface and one E1 interface to support
N×64Kbps（N=1~31）fractional E1 transmission.
RC904-V35FE1-BL series are module devices and can be installed in
Raisecom RC002-16 16 slots chassis, RC002-4 4 slots chassis and RC001-1
single slot chassis, SNMP network management is available and remote
device status also can be inquired.
2.2. Main feathers
zProvide a DCE interface for V35 synchronous data and is compliant with
ITU norm.
zProvide a 120Ωbalanced E1 interface compliant ITU-T G.703, and the
longest transmission distance is 1800m.
zUtilize ITU-T G.704 frame format to adjust the bandwidth of V35 interface.
zDiversified E1 cable alarms provide local and remote alarm index.
zSupport local and remote loop-back function for error code test.
zSupport both E1 fractional frame format and transparent frame format, and
in fractional mode all the time slots are available for configuration.
zProvide 3 kinds of clock mode: master clock (inside timing), slave clock
(follow E1 line for timing), V35 clock (follow V35 line for timing).
zThe remote device can detect the local device automatically to synchronize
time slot configuration when the devices are pair used in fractional mode.
zInside error code test module is available for variable loop back tests to
diagnose faults.
zBoth PCM30 and PCM31 are available in fractional mode, and CRC4
function is auto-adapted.
zSupport adjustment function of V35 Rx data phase.
zSupport fault pass through function, and the line fault can be tested from
the V35 interface.
zUtilize large scale ASIC chip and 4 layers of PCB, low power consumption
and high reliability.
