Infineon releases ADSL2 transceiver chipset
MUNICH,
GERMANY -- Infineon Technologies has recently released
its new asynchronous digital subscriber line (ADSL)
transceiver chipset supporting the specifications of
ADSL2 (G.dmt.bis), the latest international standard
for ADSL services. With this, telecom equipment providers
worldwide can now offer improved data rates and longer
reach to customers providing broadband services to residential
and business customers.
The
ADSL2 standard, designated as G.992.3/G.992.4 by the
International Telecommunications Union (ITU) increases
loop reach to serve a higher customer base with ADSL
service, as well as an extensive line diagnostic capabilities
and sophisticated power saving modes. Other important
features defined by the standard and supported by Infineon's
chipset are fast startup, all-digital loop (ADL) and
channelized voice.
To
support the new standard, Infineon upgraded its Geminax
(Global Enhanced Multiport Integrated ADSL Transceiver)
chipset with an ADSL2 compliant data pump. The new chip
is plug-in compatible with the existing Geminax chipset.
Equipment providers can easily upgrade their existing
line card designs by simply replacing the data pump
chip, providing significant time-to-market advantage.
The
Geminax chipset makes it possible for Infineon customers
to provide carriers with cost-effective, high density
and low power access network systems supporting transmission
of data-only or combined voice and data services. Used
in central office (CO) digital subscriber line access
module (DSLAM) and digital loop carrier (DLC) systems,
each Geminax chipset supports eight standards compliant
ADSL ports and is fully programmable to meet ADSL and
legacy analog telephony specifications. This combination
of standards compatibility and programmability simplifies
manufacturing and deployment logistics and reduces total
system cost.
Infineon
produces data-only and integrated voice/data (IVD) versions
of the Geminax chipset. The IVD version is the only
available ADSL transceiver chipset with a fully integrated
POTS splitter and support for baseband voice processing.
This level of integration can significantly reduce bill
of material (BoM) costs compared to multiboard solutions
that require bulky and expensive external POTS splitters,
ADSL line cards and a traditional POTS voice line card
for lifeline voice service. Samples of the Geminax chipset
with support for ADSL2 are now available.
