Figure 9-22. Ethernet Port BERT Diagram
The Full Channel (Roundtrip) Test requires a loopback at the far end (on the right side of the diagram). The S132
Packet BERT Pattern Generator sends a BERT Pattern to the S132 Transmit Ethernet Port. The BERT Monitor
verifies that the data returned at the Receive Ethernet Port is error free.
The Half Channel (one-way) Test requires an equivalent BERT Tester at the far end (on the right side of the
diagram). The S132 Packet BERT Pattern Generator sends a BERT Pattern to the S132 Transmit Ethernet Port.
The far end must use a BERT Pattern Monitor to verify that the data is received error free. Similarly, the far end can
transmit a BERT Pattern in the opposite direction. The S132 BERT Monitor can be used to verify that the data is
received error free.
The Packet BERT Engine can be enabled at the same time as the TDM BERT. The two BERT Engines share
several register settings, so the TDM and Packet BERT tests are not independent of each other. For Half Channel
Packet BERT Testing the Generator and Monitor must be programmed to match what is expected at the far end
(right side of Figure 9-22). There is no register setting to program the BERT Test Engine to “Full” or “Half” Channel
Testing. The connections that are external to the S132 determine the Full vs. Half Channel application.
The S132 Packet BERT Engine uses an Encap BERT Generator and a Decap BERT Monitor. The
MD.EBCR.ETBE enable/disables the Packet BERT Generator and MD.EBCR.ETBBS selects the TXP Bundle that
the generated BERT Test Pattern is to be inserted into. The BERT Test Pattern is placed in the Payload section. If
a Bundle that is programmed to support sub-channel CAS Signaling is assigned to a Packet BERT Test, the sub-
channel CAS Signaling is unaffected (not tested) by the BERT Test. The MD.DBCR.DRBE enable/disables the
Packet BERT Monitor and MD.DBCR.DRBBS selects the RXP Bundle that is to be monitored.
The Packet BERT Engine supports 3 Test Pattern Types: Pseudo-Random Bit Sequence (PRBS), Quasi-Random
Bit Sequence (QRSS) and Repetitive Patterns. The Packet BERT Generator Test Pattern Type is programmed
using EB.BPCR.PTS and EB.BPCR.QRSS. The Packet BERT Monitor Test Pattern Type is programmed using
DB.BPCR.PTS and DB.BPCR.QRSS.
For the Pseudo-Random pattern, the “z” coefficient, “y” coefficient and Seed for the X + Xy +1 PRBS pattern is
selected for the Generator using EB.BPCR.PTF, EB.BPCR.PLF and EB.BPCR.BPS; and for the Monitor using
DB.BPCR.PTF, DB.BPCR.PLF and DB.BPCR.BPS.
For the Quasi-Random pattern the PTF, PLF and BPS registers are ignored and the X20 + X17 +1 QRBS pattern is
used. The Quasi-Random pattern is similar to a PRBS pattern but with the number of “consecutive zeros" in the
pattern limited to 14.
For the Repetitive pattern, the pattern length and pattern value are selected for the Generator using EB.BPCR.PLF
and EB.BPCR.BPS; and for the Monitor using DB.BPCR.PLF and DB.BPCR.BPS. The PTF settings are ignored.
The EB.BCR register is used to program the Packet BERT Generator for New Test Pattern Load (TNPL; initiate
generation of the test pattern) and Test Pattern Inversion (TPIC).
