For Immediate Release:CXR/Larus Announces New SpeederLAN©
New Generation of LAN
Extension Solutions over Copper
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.
