The Osmocom icE1usb is a modern, software-defined open hardware and
open source firmware design for a USB E1 interface.  You can find more
information at https://osmocom.org/projects/e1-t1-adapter/wiki/IcE1usb

The hardware design can be found at https://git.osmocom.org/osmo-e1-hardware

The FPGA gateware and associated embedded firmware is hosted in the same
git repository. Some parts are in submodules (be sure to use recursive
clone)

This DAHDI driver allows t lothe use of the icE1usb just like any other
E1/PRI interface device supported by DAHDI.  When using this DAHDI
driver, osmo-e1d most not be used.  The DAHDI driver is a replacement /
alternative for osmo-e1d.
