Test Pattern Error Counter Status Register
All of the HDSL overhead status bits in this register are latched active High when detected, and
remain High until a write is done by the microprocessor.
Address: 16
Abbreviation: PATSTAT
Read/Write
Demux Power Status Register
Address: 17
Abbreviation: DXPSSTAT
Read/Write
All of the HDSL overhead status bits in this register are latched active High when detected, and
remain High until a write is done by the microprocessor.
Note:
Although the HDSL overhead indicator bits are active Low on the HDSL data stream, all status bits
in this register are active High, i.e., the status bits are inverted from what was received on the loop.
