Note: See Figure 5.3A for details on the signal flow for the status bits in the T3E3SR register.
Note: Bits that are underlined are read only; all other bits are read-write.
Bit 0 / Loss Of Signal Occurrence (LOS). This latched read only alarm status bit will be set to a one
when the T3 or E3 framer detects a loss of signal. This bit will be cleared when read unless a LOS
condition still exists. A change in state of the LOS can cause a hardware interrupt to occur if the LOS bit
in the Interrupt Mask for T3E3SR (IT3E3SR) register is set to a one and the T3E3SR bit in the Interrupt
Mask for MSR (IMSR) register is set to a one. The interrupt will be allowed to clear when this bit is
read. The LOS alarm criteria is described in Tables 5.3A and 5.3B
Bit 1 / Loss Of Frame Occurrence (LOF). This latched read only alarm status bit will be set to a one
when the T3 or E3 framer detects a loss of frame. This bit will be cleared when read unless a LOF
condition still exists. A change in state of the LOF can cause a hardware interrupt to occur if the LOF bit
in the Interrupt Mask for T3E3SR (IT3E3SR) register is set to a one and the T3E3SR bit in the Interrupt
Mask for MSR (IMSR) register is set to a one. The interrupt will be allowed to clear when this bit is read.
The LOF alarm criteria is described in Tables 5.3A and 5.3B
Bit 2 / Alarm Indication Signal Detected (AIS). This latched read only alarm status bit will be set to a
one when the T3 or E3 framer detects an incoming Alarm Indication Signal. This bit will be cleared
when read unless an AIS signal is still present. A change in state of the AIS detection can cause a
hardware interrupt to occur if the AIS bit in the Interrupt Mask for T3E3SR (IT3E3SR) register is set to a
one and the T3E3SR bit in the Interrupt Mask for MSR (IMSR) register is set to a one. The interrupt will
be allowed to clear when this bit is read. The AIS alarm detection criteria is described in Tables 5.3A and
5.3B
