Pattern-2047 BERT Test
In the Pattern-2047 BERT test, the DSU sends a 2047 bit error rate test (BERT)
pattern to the carrier network without initiating loopback (Figure 4-8)
.
Figure 4-8. Pattern-2047 BERT Test
This test allows you to connect a BERT tester at the remote end of a DDS line to
verify that data is passing over the line.
Telco-Activated Loopback
In addition to the tests you can initiate in the Configuration Manager, the
DSU/CSU supports two standard DDS loopback conditions to test local loops and
DDS termination equipment. The Telco facility initiates these tests upon customer
request:
CSU Loopback -- Isolates trouble in the network
DSU Loopback -- Like Digital Loopback, tests the local DSU/CSU and the
Telco circuit
