Name/Description
Start Test-Pattern Generator.
Writing a 1 to this register will cause the genera-
tor to start generating a test pattern based on the pattern indicated in the test-
pattern style register. Writing a 0 to this register will stop the test-pattern genera-
tion and provide the opportunity to change the test-pattern style.
Start Test-Pattern Checker.
Writing a 1 to this register will cause the checker to
start locking on to a test pattern based on the pattern indicated in the test-
pattern style register. Writing a 0 to this register will stop the test-pattern check-
ing and provide the opportunity to change the test-pattern style.
Test-Pattern Generator Highway Data Rate.
These bits are used to indicate
the highway data rate of the transmit highway selected for test-pattern genera-
tion. It must match the Tx highway data rate which was set in transmit highway
configuration register (byte 2), HDR[1—0] bits. The transmit highway selection
for test-pattern generation is done using the connection store. Only one highway
at a time can be involved with test-pattern generation. Test-pattern generation
and checking does not affect the operation of other time slots or highways.

Test-Pattern Checker Highway Data Rate.
These bits are used to indicate the
highway data rate of the receive highway selected for test-pattern checking. It
must match the Rx highway data rate which was set in receive highway configu-
ration register (byte 2), HDR[1—0] bits. The transmit highway selection for test-
pattern generation is done using the test-pattern checker highway register. Only
one highway at a time can be involved with test-pattern checking. Test-pattern
generation and checking does not affect the operation of other time slots or high-
ways.
