3 TECHNICAL DESCRIPTION
3.1 General Information
The FlexDSL GigaFlex product family is designed to support high speed data transmission over
copper andfiber cables with a complete Layer2/3 Ethernet switching functionality. Itfully complies
with the field-proven ITU-T G.991.2 SHDSL technology and IEEE 802.3ah Ethernet in the First
Mile (EFM) encapsulation. Unlike ATM encapsulation, the EFM frames have the same structure
as Ethernet IEEE 802.3 frames. This makes the bandwidth utilization more effective. The EFM-
based G.SHDSL transceiver operates as PHY (Physical Layer of OSI model). It can combine
several physical links into one logical link for obtaining more bandwidth. This process is called
bonding. SHDSL represents the best of several symmetric DSL technologies that have been
combined into a single industry standard providing rate adaptation, greater reach and
performance, spectral compatibility, lower power and application flexibility.
The FlexDSL GigaFlex product family offers the following features:
•A dual wide range 24/48VDC power input in case power supply redundancy is needed.
•An USB 2.0 Host interface to connect an additional USB flash stick for saving/restoring
configuration/firmware.
•A microSD card tray to insert a formatted microSD card with any capacity for
saving/restoring configuration/firmware.
•A Factory Default button to switch the devices configuration to factory default settings.
•Two cages for SFP modules support the 1000Base-X standard. They can be usedfor data
transmissionover fiber-optic cables as wellas copper cables (Ethernet 10/100/1000Base-
TX or VDSL2), depending on inserted SFP modules.
•Four standard 10/100/1000Base-TX Ethernet interfaces.
•Up to four SHDSL interfaces with up to 60Mbps.
•Two configurable RS232/422/485 serial interfaces.
•Two Inputs (current detection) and two Outputs (relays).
•Easy installation on DIN-rail (TS 35, EN 50022).
•Robust metal housing.

3.3 GigaFlex Interface Description
3.3.1 SHDSL Interface
The GigaFlex models are available with 2 or 4 EFM-based SHDSL channels. Every channel can
operate independently or two and more interfaces can create a group. This process is called
bonding. Up to two bonding groups can be created. A single SHDSL channel or a group of
channels carry useful data traffic, called payload.
The EFM acronym means Ethernet on a First Mile. The EFM-based SHDSL transceiver operates
as PHY (Physical Layer of OSI Model). Upper Layers of OSI Model forms data flow that should
be transmitted over physical media. The SHDSL transceiver encodes data flow using TC-PAM
(Trellis-Codded Pulse Amplitude Modulation) and sends a data flow to the receiving end over a
twisted copper pair cable.
3.3.1.1 Modulation and Data Rates
The GigaFlex firmware supports TC-PAM4/8/16/32/64/128 modulations. Here the digit means the
number of levels in a signal pulse. Less number of levels means more distance between them.
More distance between the levels means more immunity to any kind of noise.
From the other hand, a modulation with low number of signal levels carries less data bits per
single pulse. This means that high data rates are not available for modulations with low number
of signal levels.

•Normal Mode: only TC-PAM16 and TC-PAM32 modulations are supported.
•Extended Mode: offers all modulations from TC-PAM4 to TC-PAM128; extends maximum
possible data rates for TC-PAM16 and TC-PAM32 modulations.
3.3.1.2 SHDSL Annex A/B
The GigaFlex models support two PSD (Power Spectral Density) operation modes: Annex A and
Annex B. The Annex A is designed for the use in North America and has less impact on ADSL
systems if they work over neighbor pairs in the same cable. The output signal level is 13.5dBm
@ 135Ohm. The Annex B is designed for the use in Europe. The output signal level is 14.5dBm
@ 135Ohm.
3.3.1.3 Bonding Group
The GigaFlex models support up to two bonding groups. Any two from four SHDSL channels can
create bonding group 1, while other two channels can create bonding group 2. Three or
four independent channels can be added into bonding group as well. If bonding is not required,
four independent channels can work into four independent directions.
3.3.1.4 Master and Slave Mode
An SHDSL link can be created if two transceivers on it ends operate in different modes. It is
required that one transceiver is configured as Master and the other one as Slave. The GigaFlex
models can have up to four SHDSL transceivers. They all work independently and must be
configured separately. The available SHDSL settings are dependent on the Master/Slave
transceiver operation mode.

3.3.1.5.3 Daisy Chain (Line Structure)
In a daisy chain you connect the devices in series and in each device, you can add/drop
Ethernet data. This can be realized with just one or multiple copper pairs.
Figure 3-6. Daisy chain connection
3.3.1.5.4 Ring Structure
A ring structure is mainly realized to have redundancy for the data transmission. It means when
a single copper connection fails, you still have a correct working application. For a ring structure
you must enable the RSTP protocol.

circuit the Input switches its state to "closed". The Input changes its state into "open" if no current
detected in the electric circuit.
NO (normally open)
NC (normally closed)
Figure 3-10. Schematics of the inputs
Output is a pair of contacts (normally-open and normally-closed) and common wire connected to
a relay. The relay may stay either on "active" or in "inactive" state. Active state means that the
current passes through the relay coil and the common contact is connected to the normally-open
contact. Inactive state means that no current passes through relay coil and the common contact
is connected to the normally-closed one.
Figure 3-11. Schematic of the outputs
The IO status is transmitted over an IP-based channel either by UDP or by TCP messages. Point-
to-Point and Point-to-Multipoint network scenarios are supported.
Detailed configuration examples can be found in the GigaFlex Configuration Manual.
3.3.5 LCT USB Connector
The Local Craft Terminal (LCT) Type Mini-B USB connector allows local access to the command
line interface of the GigaFlex models. If connected to a PC, a new serial port will be available for
communication with the device. Start your favorite terminal emulation program and select new
serial interface to initiate configuration session.
3.3.6 SD Card and USB Host
A Micro SD card and USB flash stick can be used for saving and restoring configuration and
firmware. Check the configuration manual for details.
3.3.7 Factory Default Button, Default IP Address
It is possible to restore the default configuration of a unit if the Factory Default (FD) button will be
pressed and held for 15 seconds during boot process. The IP address will be overwritten to the
default IP address 192.168.0.235.
