note the installed DSU DIM
• Detailed Node Statistics— show DSU DIM installation

#Enter Selection:
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
External loopback
This loopback mode performs the internal loopback
mentioned above along with looping the external
transmit to the external receive to allow manual testing
of the remote interface.
