Complete G.shdsl/HDSL2/SDSL/
HDSL/IDSL Multimode DSL Solution
The ZipWireMulti eight-port multimode DSL solution
i m p l e m e n ts Mindspeed Te c h n o l o g i e s ’L o o p W i za r d
technology to diagnose line problems without expensive
test equipment or truck rolls (see LoopWizard xDSL Loop
Diagnotic Software lite r a t u r e ) . The ZipWireMulti DSL
solution goes beyond simple compliance with the ITU G.shdsl
standard by supporting the optional enhanced perfo r m a n c e
asymmetrical PSD (EPAP) modes of operation.In addition,
it complies with the ANSI HDSL2 standard (ANSI T1.418)
and provides interoperability with Mindspeed’s
market-leading ZipWire™ transceivers by operating in
2B1Q multi-rate mode. The 2B1Q mode supports
AutoBaudfor SDSL interoperability, rate optimization,
fast connect times and standards-based HDSL operation.
The ZipWireMulti also runs in IDSL mode for inte r o p e r a b i l i t y
with basic-rate ISDN repeaters. The solution supports
Mindspeed’s proprietary modes, such as 32-PAM,64 Kbps
and 3.088 Mbps operation, which provide enhanced
spectral compatibility, e x tended subscriber-line reach
and high-speed operation. One hardware circuit (i.e.,one
t r a n s fo r m e r,c rystal and hybrid) supports all these modes,
which can be configured in real time via software control.
Embedded Microprocessor
The ZipWireMulti chipset includes an embedded A R M
m i c r o p r o c e ssor and a full suite of s o f t ware that
fa c i l it a tes speedy, s i m p l i fied development of s y s tems that
comply with all applicable ITU, ANSI and ETSI standards.
The embedded microprocessor and software handle the
EOC processing and many other functions often delegate d
to an external host controller in competing solutions. This
greatly reduces software-porting effort and eliminates
real-time processing requirements for an external host
controller. The host controls the ZipWireMulti through a
simple and well-defined software API structure while the
internal ARM processor handes all real-time processing.
UTOPIA and PCM Interfaces Operate
Simultaneously
The ZipWireMulti’s integrated framers include
full-featured UTOPIA Level 2 and PCM interfaces. The
UTOPIAinterface includes ATM TC-layer processing.
The DSL payload can be mapped to either interface, or
split between them to enable simultaneous connections
to ATM- and TDM-based syste m s. This feature is
programmable on a per-port basis, and supports a mix
o f channels transporting data, data plus time slot voice,
or only time slot voice.

Product Highlights
The framer automatically extracts and inserts DSL overhead
(i.e., EOC,indicator and Z-bits, CRC,sync word, etc.) and passes
it to the embedded microprocessor for processing.
In addition,the framer supports all G.shdsl, HDSL2, HDSL
and IDSL frame formats; EOC messaging protocols; and other
non-standard SDSL frame formats. For non-framed protocols,
the ZipWireMulti supports a framer bypass mode.
Integrated Line Driver and Frequency Synthesizer
The ZipWireMulti includes an integrated line driver and
frequency synthesizer for a full DSL solution.The integrated
line driver can drive the high line-power EPAPs for payload
rates of768; 1,544; 2,048; and 2,304 Kbps, in compliance with
the G.shdsl standard.The frequency synthesizer, along with
the rest ofthe ZipWireMulti,supports data rates from 64
Kbps to 3.088 Mbps, and requires only one external crystal.
This highly integrated DSL solution enables OEMs to design
and manufacture the most feature-rich, lowest-power, and
highest-density DSL equipment in the industry.
