NAME

ueagle — Analog Devices Eagle ADSL modems

SYNOPSIS

ueagle* at uhub? port ?

DESCRIPTION

The ueagle driver provides support for USB ADSL modems based on the Analog Devices Eagle chipset (revision I, II and III).

The ueagle 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 ueagle driver uses USB isochronous pipes instead of standard bulk pipes.

To establish a permanent virtual circuit (PVC) with a peer, ueagle must be configured using the route(8) command. A typical invocation is:

# route add -iface <Peer IP> -link if:encap.vpi.vci_hi.vci_lo

The arguments to “-link” are as follows:

See also EXAMPLES below.

HARDWARE

The following modems should work:

FILES

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

These firmware files are not free because Analog Devices refuses to grant distribution rights.

A prepackaged version of the firmware can be installed using fw_update(1).

EXAMPLES

To establish a PVC (vpi=8, vci=35, vcmux) with host 192.168.1.2:

# route add -iface 192.168.1.2 -link ueagle0:1.8.0.23

To establish a PVC (vpi=0, vci=6, llc/snap) with host 192.168.1.3:

# route add -iface 192.168.1.3 -link ueagle0:3.0.0.6

SEE ALSO

HISTORY

The ueagle driver first appeared in OpenBSD 3.8.

AUTHORS

The ueagle driver was written by Damien Bergamini <damien@openbsd.org>.

CAVEATS

The ueagle 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.
