DTE With Test Pattern
The
DTE
WITH
TP
(test pattern) test is similar to the

described previously except the test pattern is generated in the
DSU using the DSU/CSU internal test pattern generator. This test
can be used to detect deficiencies within the internal drivers and
receivers of the DSU IV ESP. Figure 13-8 illustrates the loopback
point and the data paths for this test.
