Test Pattern Test
This test allows you to test the local MT56DSU-R, the
communications link, and the remote MT56DSU-R.
With this test enabled, the MT56DSU-R sends and detects a pre-
defined 15-bit pseudo-random test pattern. When an error is
detected by the MT56DSU-R, the NS (No Signal) LED flashs.
To enable the Test Pattern Test, perform the following.
1.
Set the DIP switch # 10 on both the local and remote
MT56DSU-R boards to the down position.
2.
The test pattern is generated and either detected as a good test
pattern (test patterns match) or as a failed test (test pattern
received does not match the pattern sent).
