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 TWatch PRO commands. The DTE (or the external test
equipment) must provide a test pattern to check the DTE
interface.
