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 -link if:encap.vpi.vci_hi.vci_lo
The arguments to ``-link'' are as follows:
if Interface name. For example, ``ueagle0''.
encap Type of encapsulation to use. Possible types are:
AAL5 VCMUX Use hex value 0x1.
AAL5 LLC/SNAP Use hex value 0x3.
vpi See ISP's recommended setting for this. All values specified
in hex.
vci_hi
vci_lo 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''.
