MtH2405 SDSL2/HDSL2 Dual Transceiver
(Product Brief)
Advanced Multi-Mode DSLTM Integration
The MtH2405 chipset solution is integrated in Metalink's Multi-Mode DSLTM, and can operate in the following DSL modes: Multirate SDSL2, HDSL2, Multirate SDSL and HDSL.
Key Features :
Dual SDSL2/HDSL2 Transceiver
Metalink's MtH2405 Chipset Solution implements a low power Dual SDSL2/HDSL2 transceiver. Each transceiver implements PAM 4, 8, 16 line codes with trellis coded modulation and by-passable OPTIS spectral mask shaping.
ANSI, ETSI and ITU Standards Compliant
Flexible internal architecture that enables the MtH2405 to be compliant to both the ANSI HDSL2 (PAM16 line code with Trellis Coded Modulation and OPTIS spectral mask) and the emerging ETSI-SDSL standards.
Optimized for High Density SDSL2 Line Card Designs
Metalink's MtH2405 has a high level of functionality and interface integration, minimal power consumption and a small real estate.
2B1Q Backward Compatibility
Backwards compatible 2B1Q mode fully interoperable with Metalink's 2B1Q SDSL chipsets. Supports all the Metalink software features already available in the Metalink SDSL1/HDSL1 solutions and uses same API.
Superior Performance
The Metalink Dual SDSL2/HDSL2 Chipset Solution enjoys a performance improvement of up to 6db compared to HDSL1 chipsets, and reaches the full CSA loop coverage over a single copper pair. This performance improvement translates into an improved system distance reach of more than 2000 feet (650 meters) at 2,320 Kbps, and of more than 6500 feet (2000 meters) at the lower transmission rates.
Applications:
SDSL2 line cards in Broadband access
DSLAMs
Suitable for the Transport of Both Voice and Data
With a minimal transmission delay of less than 0.5 msec., Metalink's SDSL2/HDSL2 Dual Transceiver is ideally suited for the transport of voice, data or a mix of voice and data communications.

MtH2415 Metalink's Dual SDSL2/HDSL2 DSP
The MtH2415 SDSL2/HDSL2 DSP is a dual SDSL2/HDSL2 transceiver on chip. It performs digital functions such as channel precoding of the SDSL2/HDSL2 Transceiver to achieve a high quality echo free signal, with optimal decoding. The DSP includes Metalink's proprietary algorithmic innovations for optimal decoding with reduced power consumption.

MtH2446 Metalink's SDSL2/HDSL2
Metalink's MtH2446 Analog Front End provides the analog interface to the copper pair. The MtH2446 AFE transmit and receive filters can be user programmed for upstream or downstream operation for the generation of a standards compliant OPTIS spectral mask. The MtH2446 AFE is particularly suitable for multirate DSL operation and enables the MtH2405 SDSL2/HDSL2 Transceiver to transmit at up to 16.5 dBm over the copper pair.
