Note: All bits in this register are latched and can create interrupts.
Bit 7: Jitter Attenuator Limit Trip Clear (JALTC). This latched bit is set when a jitter attenuator limit trip condition
was detected and then removed.
Bit 6: Open-Circuit Clear (OCC). This latched bit is set when an open-circuit condition was detected at TTIP and
TRING and then removed.
Bit 5: Short-Circuit Clear (SCC). This latched bit is set when a short-circuit condition was detected at TTIP and
TRING and then removed.
Bit 4: Loss of Signal Clear (LOSC). This latched bit is set when a loss-of-signal condition was detected at RTIP
and RRING and then removed.
Bit 3: Jitter Attenuator Limit Trip Set (JALTS). This latched bit is set when the jitter attenuator limit trip condition
is detected.
Bit 2: Open-Circuit Detect (OCD). This latched bit is set when an open-circuit condition is detected at TTIP and
TRING. This bit is not functional in T1 CSU operating modes (T1 LBO 5, LBO 6, and LBO 7).
Bit 1: Short-Circuit Detect (SCD). This latched bit is set when a short-circuit condition is detected at TTIP and
TRING. This bit is not functional in T1 CSU operating modes (T1 LBO 5, LBO 6, and LBO 7).
Bit 0: Loss of Signal Detect (LOSD). This latched bit is set when an LOS condition is detected at RTIP and
RRING.
