Larscom's Orion 2000 provides standard-based Inverse Multiplexing over ATM (IMA),
offering connectivity up to 12 Mbps over T1 lines, or up to 16 Mbps over E1
lines. The Orion 2000 is ideal for applications where higher-rate ATM WAN
connections are either unavailable or cost prohibitive. Built to central office
standards, the Orion 2000 is equally suited to private ATM LAN interconnection
and deployment by Network Service Providers. The Orion 2000 offers superior
traffic management, with an exceptionally large 1 MB buffer divided into four
queues (a total of 16,384 cells) to effectively handle high-rate bursts. Sizes
and thresholds for three of the queues, plus discard and congestion-management
options, are user configurable for optimal performance. Sophisticated ASCII
terminal and SNMP management interfaces enable local or remote configuration,
performance monitoring, alarm notification, and diagnostic testing. The Orion
2000 is interoperable with all leading DSLAMs, IMA concentrators, ATM core
switches, and routers, ensuring you a proven, readily-available, rock-solid IMA
solution for a wide range of applications .
The basic function of the Orion 2000 is to interconnect ATM
devices point-to-point across a wide area using multiple T1/E1 lines. Virtually
any ATM device (e.g., routers, switches, DLSAMs, hubs, workstations) can be
interconnected, as long as each has a DS3, E3, or OC-3c/STM-1 UNI/NNI port. Use
of inverse-multiplexed T1s or E1s for the WAN link provides major cost and
availability benefits over DS3, E3, or OC-3c/STM-1 ATM WAN links.
