+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.
