Loopback Options

DSU Internal Loopback	This loopback mode does not affect the external
	interface but it does loop the local transmit data back to
	the receive data within the EIM. This test is useful for
	verifying that the EIM is connected and is working
	properly from a digital integrity perspective.
DSU Internal and	This loopback mode performs the internal loopback
External loopback	mentioned above along with looping the external
	transmit to the external receive to allow manual testing
	of the remote interface.
