Equinox Systems Inc. designs and markets server-based communications products. Equinox categorizes its products by how they are attached to servers, either Bus-attached or LAN-attached. Bus-attached products plug directly into bus expansion slots in the server's motherboard, and LAN-attached products connect to the server through an Ethernet LAN. The Company's Bus-attached product offerings consist of the SuperSerial product line and the Modem Pool product line (with both Analog and Digital models). The Company's ELS Terminal Server and DSS product lines comprise its LAN-attached product offerings. The Company broadened its LAN-attached product offerings with the introduction of the Ethernet Serial Provider (ESP) in 1999. (Source: 10-K405)
