DTE Interface Loopbacks

The Nx56K/64K serial interface offers a DTE loopback. See
Figure 7-4.
DTE Loopback
Loops all data from the DTE back towards the DTE. This loopback
may be initiated by using the front panel or T-Watch PRO
commands. The DTE (or the external test equipment) must provide
a test pattern to check the DTE interface.
