802.3ah compliant SHDSL EFM Line Cards for MALC

Overview

The MALC SHDSL EFM line cards have been designed to deliver high-speed Ethernet services over SHDSL. The line card provides high-density, EFM-compliant SHDSL aggregation with advanced features such as Zhone's Multimedia Traffic Management (MTM) and fully integrated OAM features for advanced management of Ethernet lines. Supporting both 802.3ah EFM standards as well as Zhone's proprietary Ethernet bonding technologies, the MALC EFM SHDSL line cards are the most flexible Ethernet aggregation product available. This dual-mode of operation allows existing customers of Zhone's legacy IPD12000/4000 IPD DSLAM and SHDSL extenders (i.e. SNE2000 and ETHX-2100 series extenders) to continue to use these devices, while easily migrating to the MALC platform and the newer generation of 802.3ah EFM compliant Ethernet extenders (e.g. ETHX-3000, ETHX-3200, ETHX-3300, and ETHX-3400 series devices).

Available in four (4) different models, the MALC-EFM-SHDSL-24 line cards offer a wide array of deployment options. All MALC-EFM-SHDSL-24 line cards support TCPAM4, TCPAM8, TCPAM16, and TCPAM32 constellations and can provide symmetric bandwidth of up to 5.7 Mbps per SHDSL port. Furthermore, all models support the ability to bond up to eight (8) SHDSL ports together to increase the total bandwidth available to the subscriber. Finally, when operating in the standards-based, 802.3ah EFM mode, cross-card bonding is supported to maximize the use of all available SHDSL ports in a MALC chassis.

Extended rate models (i.e. MALC-EFM-SHDSL-24-NTP-EXT / MALC-EFM-SHDSL-24-NTWC-EXT) can also be provisioned to support TCPAM64 constellations to increase the available bandwidth up to 12.7 Mbps per port. TCPAM64 constellations are most useful in in-building and/or campus environments where loop plant conditions are generally cleaner and where CAT5 cabling can be made available to maximize the available SNR margins and minimize the effects of extraneous noise.

The MALC-EFM-SHDSL-24-NTP / MALC-EFM-SHDSL-24-NTP-EXT cards can each provide a network timing reference and line power. This allows an SHDSL CPE to derive timing from the input of the SHDSL lines and use that timing/clocking to provide timing to other subtended devices. The line power feature can be used to power up to twelve (12) CPEs devices (such as Zhone's SkyZhone) to eliminate the need for local power at these remote sites.

The MALC-EFM-SHDSL-24-NTWC / MALC-EFM-SHDSL-24-NTWC-EXT cards can each provide a network timing reference and wetting current.
