Wanpipe WAN API

Legacy API Modes

The Sangoma AFT DATA API is a common DATA (non-voice) api for the following data cards:

WAN API Modes:

HDLC Mode
The sample application runs on top of a hdlc interface and receives
HDLC formated frames. HDLC framing is done in AFT hardware.
----
Transparent (Bitstreaming) Mode
The sample application runs on top of a raw transparent interface and receives
all bits on the line in configurable block size. HDLC framing is turned off in hardware.
-----
Protocol API Mode
The AFT API can run on top of a protocol interface such as: PPP, CHDLC, ATM, Frame Relay.
We treat the protocol interface as data pump and are able to receive and transmit
protocol payload only. The interface protocol in the driver is responsible for attaching
appropriate protocol headers on tx and rx.
