For Immediate Release: CXR/Larus Announces New SpeederLAN©
San Jose, Calif., May 31, 2005 – CXR/Larus, a manufacturer of network timing, test and access solutions today announced the newest generation of LAN extension solutions over copper, the SpeederLAN family. Based on CAP SDSL or TC-PAM G.SHDSL technology, and upgradeable by the user, this Ethernet bridge switch has the capability to concentrate several DSL links or aggregates them into one high speed trunk, in order to increase the rate of the LAN interconnection up to 13.8Mbps. First shown at CeBIT 2005 in Hanover, Germany, the SpeederLAN brings innovative and cost-effective solutions for LAN-to-LAN interconnection over unused copper or in-service phone wire pairs. The SpeederLAN is designed for military campuses, harbor/airport/underground infrastructures, or industrial complexes, or for connecting remote installations in an urban community. The SpeederLAN-DU concentrates two independent LAN extensions from two Ethernet interfaces through two SDSL links up to 4.6Mbps or with G.SHDSL (2.3Mbps) to achieve a reach of up to 7.2km (4.47 miles) with 26 AWG/0.4mm wire, or 22km (13.67 miles) on 19 AWG/0.9mm wire. The DSL links would be terminated by either a CopperLAN or a CopperLAN-SW or with the popular MD20BT that has been widely deployed worldwide. The SpeederLAN-DU can be used to support the concentration of up to 16 DSL links in a 19’’ rack. The SpeederLAN-AG aggregates three SDSL links to provide a high- speed trunk and can aggregate up to 4 G.SHDSL links. This solution provides users with a LAN extension full duplex rate of up to 13.8Mbps. This bridge can also act as a micro-DSLAM, supporting up to three independent loops with speeds up to 4.6Mbps SDSL or 2.3Mbps G.SHDSL terminated by a CopperLAN, CopperLAN-SW or MD20BT CPE unit. The SpeederLAN’s simple plug-and-play installation comes from its automatic rate adaptation from 64Kbps to 4.6Mbps, depending on line quality and length. The SpeederLAN-AG has an elaborated Level 2 HDLC layer, enabling fully-automatic link control when a new copper pair is installed or when a line is failing. Its advanced 10/100Base-T bridge is transparent to VLAN frames. This allows either a transparent or filtering transport of the local traffic thanks to its 1,280 Ethernet frame buffer and storage capacity of more than 1,000 MAC addresses, and the permanent control of the Ethernet traffic during transmission. Like a DSL switch, the SpeederLAN-SW is able to create a port-based VLAN. The SpeederLAN, like all new CXR/Larus equipment for LAN extension over copper, PDH or SDH, is highly manageable with current status and 24 hour statistics available locally or over the LAN. It answers ping requests and setup via a Telnet session. It may be controlled by an SNMP manager with GET and TRAP. A graphical MIB is supplied for SNMPC. SpeederLAN is available in a desktop model with a metallic case, AC or DC supply, or in a rack card for CXR systems with centralized SNMP management. About CXR/Larus CXR/Larus Corporation is comprised of three telecommunication units of EMRISE Corporation, an international manufacturer of defense and aerospace electronic components, subsystems and telecommunications equipment with operations in the US, France, UK and Japan. Together, these business units combine common technologies and markets to develop transmission and network access products, timing and synchronization systems, and test instruments for a global marketplace. The focus is on providing equipment to meet the emerging requirements for voice, data and video transport, synchronization and timing, and testing for public and private networks.
