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 ’

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

AutoBaud

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.
