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.
