Características |
|
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 with greater speed.
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 ringbuffer
DMA architecture, the A301 provides 132 Mbps of PCI bus transfer capacity with minimal real-time processor load.
The A301 Clear Channel T3/E3 Card is based on the same advanced engineering design as the award-winning AFT Product Line. Trust the Sangoma® name to deliver optimum data support on standard telecommunications networks. |
