Digital Test
The Digital Test (DT) verifies operation of a pair of
DSUs and the data circuit between them. When a Digital
Test is performed on a specific port, data transmission is
not affected on the other ports.
For a DSU operating in single-port mode and having
either nondisruptive diagnostics or rate adaption in effect,
an additional selection for Aggr or Prt1 appears.
Selecting Aggr tests the looped data path; in-band
communication transport data is not allowed.
End-to-End Test
The End-to-End (EE) test analyzes a control and a
tributary DSU or DBM and the network circuit between
them in both directions independently. Refer to Document
No. 3610-A2-GB46 for additional information.
Bit Error Rate Test
The Bit Error Rate Test (BERT) is session-disruptive
and transmits a test pattern to analyze the network circuit.
Refer to Document No. 3610-A2-GB46 for additional
information.
Dial Tone Test
The Dial Tone test (DTone) allows a DBM to test for
dial tone. This selection does not appear in the DSU’s Test
branch.
