The Sangoma A108DE is an 8 Port T1 PCIe Card that supports eight T1/E1 or fractional T1/E1 data streams. The A108DE also offers 1024 tap (128ms) hardware based echo cancellation across 240 channels.
The A108DE offers support for up to 16.4Mbps of full-duplex data throughput, or as many as 240 simultaneous voice calls over eight T1 and or E1 lines, supporting high performance PCIe-based routing and telephony systems. Advanced clocking features allow E1 and T1 lines to be mixed with full synchronization.
The A108DE is also field upgradeable, which allows it to take advantage of hardware and software improvements as they become available.
