The test programs in this Hg repository are being developed ahead of the needed
hardware.  These programs are intended to run on a machine equipped with an
icE1usb adapter (more specifically, one that is capable of bringing up both E1
interfaces on that adapter) and running osmo-e1d, with the two E1 circuits out
of icE1usb connected to A and Ater interfaces of Nokia TCSM2 bank-of-TRAUs
apparatus.

As of this writing, the additional TCSM2 components that bring out the E1
circuits have not been procured yet; the needed icE1usb device is likewise
still on order.  In the meantime, test programs that are ultimately intended
for exercising the TRAU are being developed in a virtual environment, using
osmo-e1d with vpair interfaces.
