The A301 card is a 2U PCI
adapter that supports clear channel T3 (44.7 Mbps) and E3 (34.4 Mbps)
over dual BNC connectors.
Based on bus mastering PCI technology supported by a ring-buffer DMA
architecture, the A301 provides 132 Mbps of PCI bus transfer capacity
with minimal real-time processor load. The A301 is ideal for larger
organizations or ISPs that have outgrown their multiple T1 or DSL
links. The A301 allows these users to take advantage of the relatively
low cost of T3/E3 connections when compared to multiple T1 or E1 lines.
