Larscom's New Orion 4510 Provides Economical Delivery of Ethernet Services
Across DS-3 Facilities For Carriers and Enterprise 


NEWARK, Calif., June 21  /PRNewswire-FirstCall/ -- Responding to the increasing
demand for Ethernet Services, Larscom (NASDAQ:LARS) today announced that it has
added another cost-effective Ethernet delivery solution to its product
portfolio.  The Orion 4510 Ethernet over DS-3 unit makes it simple and
economical for carriers and enterprises to provide broadband access, deliver
high-speed Ethernet services, and extend the LAN services within the
enterprise, including the transport of Ethernet services to remote locations.

The Orion 4510 is optimized to support Fast (100 Base-T) Ethernet. Depending on
the application, it maps Ethernet frames into a DS-3 bit stream or maps DS-3 to
Ethernet to enable Ethernet transport across the existing infrastructure.

It includes Larscom's comprehensive, easy-to-use installation and management
facilities.  Traffic flow control ensures Ethernet service quality.

The compact Orion 4510 form factor is designed to minimize space requirements
and operating expenses for deployment at the customer premises.

"Many of our customers are looking for economical ways to deliver and transport
Ethernet services across their existing infrastructure," said Gurdip Jande,
vice president of marketing at Larscom.  "Now Larscom offers a new price point
for Ethernet over DS-3 and combines it with our hallmark ease of use, to
provide a complete solution that integrates easily into any carrier or
enterprise DS-3 network."

The new Orion 4510 is the next step in Larscom's Ethernet solutions strategy,
which also includes the Orion 7400 Ethernet Multi-Service Access Platform for
the delivery of Ethernet over SONET.  The Orion 4510 is available today.
