1 Product overview
1.1 Overview
The RC1104-FE-4W is the G.SHDSL modem developed by Raisecom, supporting the
G.SHDSL.BIS feature. It uses two pairs of twisted-pair cables (bare wire) for transmission
with the maximum transmission rate of 2 ×11.4 Mbit/s. The RC1104-FE-4W can be used to
transmit signals through networks when the rate keeps at 2 ×5.7 Mbit/s and the Ethernet lines
are extended to 2.6 km.
The RC1104-FE-4W adopts the serialization design, featuring high versatility and
intellectuality. Moreover, it is a modular device, characterized by high reliability, small size,
low power consumption, easy operation, and friendly maintenance. The RC1104-FE-4W can
be inserted into a 19-inch 3U standard RC002-16 chassis (providing 15 service slots) installed
in the rack. It can also be inserted into the single-slot chassis RC001-AC to work at the user
end independently. Through the NView NNM system, comprehensive configurations and
monitoring of local and remote devices can be realized.
1.2 Features
Support dual-line pair transmission with the wire diameter of 0.4 mm, and support the
transmission distance of 2.6 km at the rate of 2 ×5.7 Mbit/s and 4.3 km at the rate of 2 ×
2.3 Mbit/s.
The transmission rate can be adjusted according to the transmission distance and line
quality. The rate of each line pair ranges from 64 Kbit/s to 11392 Kbit/s.
Support ETH interface rate limiting, ETH interface performance statistics, and
G.SHDSL interface performance statistics.
The G.SHDSL interface supports EFM bonding.
The G.SHDSL interface supports Lineprobe and AutoPAM.
Support the maximum frame length of 1589 Bytes.
Support the transmission mode: full duplex and echo cancellation.
The user interface is 10/100 Mbit/s self-adaptive Ethernet interface.
Be easy in use and installation, and be able to configure and manage remote devices.
Support good heat dissipation, which can effectively lower the temperature.

3.2 Verifying cable type
0.4 mm (American standard 26 AWG)/0.5 mm/0.6 mm telephone wire
3.3 Connecting to other device (G.SHDSL interface)
Requirements are as below:
STU-C and STU-R are configured in pair.
The rate should be configured in the same range.
The Annex mode should be the same.
The PAM mode should be the same.
The Tx power should match (the standard G.SHDSL supports auto-negotiation).
When remote network management is used, the local device and remote device should
be configured to master and slave modes respectively.
3.4 Connecting to the same device
When the RC1104-FE-4W series devices are interconnected with each other, the following
requirements on models should be met. Otherwise, the link is disconnected or the data are
transmitted improperly.

3.9 Actual line measurement
The common telephone wire (wire diameter: 0.4 mm/0.5 mm/0.6 mm) is used as the
connecting line. Use a multimeter to measure the impedance of the loop after the carrier
makes the telephone wire into a loop.

The table above provides the rate of the G.SHDSL single-line pair. The rate of the dual-line
pair doubles that of the single-line pair. Moreover, the comparison table lists the result tested
in the laboratory without consideration of the interference noise. In actual applications, the
transmission distance may vary due to the line quality and interference. So this table is just for
your reference.
