TECHNICAL DESCRIPTION

General Information
The FlexDSL GigaFlex product family is designed to support high speed data transmission over
copper and fiber cables with a complete Layer 2/3 Ethernet switching functionality. It fully 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 used for data
transmission over fiber-optic cables as well as 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.
