ZipWirePlusď›› G.shdsl Transceiver with Embedded Microprocessor
Multimode Operation: G.shdsl+, HDSL2, SDSL, and HDSL
The ZipWirePlus multimode DSL solution goes beyond simple
compliance to the ITU-T G.shdsl standard by supporting the optional
Enhanced Performance Asymmetrical PSD (EPAP) mode of
operation. In addition, it is compliant with the ANSI HDSL2 standard
(ANSI T1.418) and provides interoperability with Mindspeed’s
market-leading ZipWire transceivers through operation in 2B1Q
multirate mode. The 2B1Q mode includes support of AutoBaud for
SDSL interoperability, rate optimization and fast connect times, as
well as standards-based HDSL operation. The ZipWirePlus also
supports Mindspeed’s own proprietary modes, like 32-PAM, 64 kbps
and 4.6 Mbps operation, which provide enhanced spectral
compatibility, extended subscriber line reach, and high-speed
operation. All modes are supported by a single hardware circuit (i.e.,
one transformer, crystal, and hybrid) and can be configured in real
time via software control.
