Test Equipment BPV Selection: A 1 enables the decoder to detect cod-
ing violations as found in ‘Type 1’ test equipment. A 0 enables the decoder
to detect coding violations as found in ‘Type 0’ test equipment. The follow-
ing tables summarize the two decoding procedures for coding violations:
Path Signal Label Error Enable AIS: A 1 enables the channel to send
DS3 or E3 line AIS automatically towards the receive line, and path RDI
when a PSLERR or C2EQ0 alarm occurs. (See RAMRDI and RAISEN for
logic diagrams).
Reserved: Must be set to zero when register is written.

tors’ and the test pattern analyzer’s pattern to be 2
tern generators’ and analyzer’s pattern to be 2
Enable Analyzer: A 1 enables the 2
are counted in a 16-bit counter in locations XAEH and XAFH.
Transmit Analyzer Enable: A 1 connects the analyzer to the transmit
NRZ line (DS3/E3) signal after the line decoder. A 0 connects the analyzer
to the receive NRZ line data prior to the line coder function. A 1 must be
written to control bit ENANA (bit 3) for this bit to function (see Figure 36).
Transmit Test Pattern Generator Enable: A 1 enables the transmit test
pattern generator and disables the NRZ line decoder output.
Receive Test Pattern Generator Enable: A 1 enables the receive test
pattern generator and disables the NRZ line coder input from the desyn-
chronizer.
Test B3 Byte: A 1 transmits a B3 value written by the microprocessor in
location X40H. A 0 enables the test byte to become a test mask. When
configured as a test mask, a 1 in one or more bit positions causes those
bits in the transmitted B3 byte to be inverted from their calculated values.
