SBS Rolls Out DS3/E3 ATM AdvancedMC Module for Telecommunications

3/24/2005 - SBS Technologies, Inc. (NASDAQ: SBSE), a leading designer and manufacturer of modular communication solutions, continues its role as an embedded network industry market leader by introducing the newest member of its Telum 1000 line - the Telum1001-DE DS3/E3 ATM network adapter. The single-wide, full height Telum 1001-DE adapter is designed for applications requiring full-duplex DS3/E3 ATM Wide Area Network (WAN) connectivity such as DSLAMs, wireless networking, router/gateways, streaming video, and protocol internetworking.

"The TELUM 1001-DE marks the second entry for SBS Technologies in the company's AdvancedMC module line-up. Customers are demanding the high bandwidth capabilities of PCI Express, manageability with IPMI and hot swap capabilities that existing solutions such as PMC/PTMC cannot deliver. We recognized the need for modular, high-performance mezzanine cards very early, introducing the industry’s first WAN AdvancedMC in June of 2004," said Rubin Dhillon, General Manager of the SBS Technologies Communications design center in Massachusetts. "Our new DS3/E3 ATM AMC WAN module is the latest in a line of field-hardened ATM networking products and is part of our comprehensive line of telecomm, datacomm, Ethernet, storage and enterprise I/O modules."

The TELUM 1001-DE is a PICMG AMC.0 & AMC.1 module that complies with ATM Forum UNI 3.1 and TM 4.0 specifications and is based on an advanced ATM Segmentation and Reassembly (SAR) Controller designed to optimize bus transfers. The TELUM 1001-DE supports one full-duplex ATM DS3/E3 port for protocol data unit sizes as small as two cells. The traffic management co-processor within the SAR supports Constant Bit Rate (CBR) and Variable Bit Rate (VBR) among other bit rates. Users can assign parameters to the xBR traffic block to maximize line utilization by automatically scheduling each virtual channel connection (VCC).

In accordance with AMC.0 specifications, an IPMI microcontroller subsystem initializes board-level parameters, monitors board voltage and temperature, maintains system status and hot-swap operations. The Channel and Digital Service Unit (CSU/DSU) network management subsystem provides line alarm conditions and performance data monitoring statistics to help managers keep tabs on line performance. The CSU/DSU functions run in an on-board microcontroller allowing Facilities Data Link functions to be performed in hardware rather than on the hosts system like other competing products.

SBS provides a portfolio of drivers which are based upon a set of libraries, known as the Driver Development Kit (DDK). The DDK architecture is common to all SBS WAN products and enables customers to use High-level drivers or low-level function calls for applications development. The TELUM 1001-DE product is provided with Carrier Grade LINUX, VxWorks & Windows drivers as well as the comprehensive DDK.

Price and Availability
Available now, the full-duplex Telum 1001-DE DS3/E3 ATM AMC module lists for US$1836.
