Analog Devices Eagle ADSL modems
ueagle* at uhub? port ?
driver provides support for USB
ADSL modems based on the Analog Devices Eagle chipset (revision I, II and
driver can only manage a single
ATM AAL5 virtual circuit. The segmentation and reassembly (SAR) of ATM cells
is done by software.
To achieve high rate downstream transfer with fast ADSL connections, the
driver uses USB isochronous pipes
instead of standard bulk pipes.
To establish a permanent virtual circuit (PVC) with a peer,
must be configured using the
typical invocation is:
# route add -iface <Peer IP> -link if:encap.vpi.vci_hi.vci_lo
The arguments to “-link” are as follows:
- Interface name. For example, “ueagle0”.
- Type of encapsulation to use. Possible types are:
- AAL5 VCMUX
- Use hex value 0x1.
- AAL5 LLC/SNAP
- Use hex value 0x3.
- See ISP's recommended setting for this. All values specified in hex.
- See ISP's recommended setting for this. All values specified in hex. The
VCI is specified as high_order_byte.low_order_byte. For example, a VCI of
35 would be specified as “0.23”.

The adapter needs some firmware files, which are loaded on demand:

driver only supports ADSL over
POTS. ADSL over ISDN is not supported. G.Lite modulation (aka splitterless)
has never been tested and probably won't work.
