Register 0x049, 0x149, 0x249, 0x349, 0x449, 0x549, 0x649, 0x749:
This register allows control over the path status byte. For more details refer to the Operation
Section of this document.
G1[0]:
PRDI, EPRDI6, EPRDI7]:
TPOP Path Status
The G1[0] bit is inserted in bit 0 the Path Status Byte G1. This bit is currently undefined by
SONET/SDH standards and should be set to 0.
The PRDI, EPRDI6 and EPRDI7 bits are inserted in bits 5, 6 and 7 of the Path Status Byte
G1 respectively. The following describes the operation of these registers based on the
EPRDIEN and EPRDISRC configuration bits in register offset 0x40.
The value specified in the table by “AUTORDI” and “AUTOERDI” are the automatic path
RDI and enhanced PRDI responses as configured in the Auto RDI and Auto Enhanced RDI
configuration registers (offset 0x09, 0x0A and 0x0B). The path RDI response is enabled by
the channel AUTOPRDI bit in register offset 0x05.
When auto path alarm operation is desired, the APRDI, PRDI and G1[1:0] registers should
be set low.
