Signaling Interrupt Status.
This bit is one when the corresponding CASRL bit in the T1 Receive
Line Status and Timer Latch - R Address Y25 is set, and the corresponding CASRM bit in the T1
Receive Line and Timer Interrupt Mask - R/W Address Y45 is unmasked. This bit is cleared when
either this register, or the latched status register is read.
One Second Interrupt Status.
This bit is one when the corresponding ONESECL bit in the T1
Receive Line Status and Timer Latch - R Address Y25 is set, and the corresponding ONESECM
bit in the T1 Receive Line and Timer Interrupt Mask - R/W Address Y45 is unmasked. This bit is
cleared when either this register, or the latched status register is read.
Two Second Interrupt Status.
This bit is one when the corresponding TWOSECL bit in the T1
Receive Line Status and Timer Latch - R Address Y25 is set, and the corresponding TWOSECM
bit in the T1 Receive Line and Timer Interrupt Mask - R/W Address Y45 is unmasked. This bit is
cleared when either this register, or the latched status register is read.

E1 Counter Interrupt Mask - R/W Address Y45 is unmasked. This bit is cleared when either this
register, or the latched status register is read.
Frame Alignment Signal (FAS) Error Counter Overflow Interrupt.
This bit is one when the
corresponding FEOL bit in the E1 Counter Latched Status - R Address Y25 is set, and the
corresponding FEOM bit in the E1 Counter Interrupt Mask - R/W Address Y45 is unmasked.
This bit is cleared when either this register, or the latched status register is read.
Frame Alignment Signal (FAS) Error Counter Indication Interrupt.
This bit is one when the
corresponding FEIL bit in the E1 Counter Latched Status - R Address Y25 is set, and the
corresponding FEIM bit in the E1 Counter Interrupt Mask - R/W Address Y45 is unmasked.
This bit is cleared when either this register, or the latched status register is read.
Frame Alignment Signal (FAS) Bit Error Counter Overflow Interrupt.
This bit is one when
the corresponding BEOL bit in the E1 Counter Latched Status - R Address Y25 is set, and the
corresponding BEOM bit in the E1 Counter Interrupt Mask - R/W Address Y45 is unmasked.
This bit is cleared when either this register, or the latched status register is read.
Frame Alignment Signal (FAS) Bit Error Counter Indication Interrupt.
This bit is one when
the corresponding BEIL bit in the E1 Counter Latched Status - R Address Y25 is set, and the
corresponding BEIM bit in the E1 Counter Interrupt Mask - R/W Address Y45 is unmasked.
This bit is cleared when either this register, or the latched status register is read.
CRC-4 Error Counter Overflow Interrupt.
This bit is one when the corresponding CEOL bit in
the E1 Counter Latched Status - R Address Y25 is set, and the corresponding CEOM bit in the
E1 Counter Interrupt Mask - R/W Address Y45 is unmasked. This bit is cleared when either this
register, or the latched status register is read.
CRC-4 Error Counter Indication Interrupt.
This bit is one when the corresponding CEIL bit in
the E1 Counter Latched Status - R Address Y25 is set, and the corresponding CEIM bit in the
E1 Counter Interrupt Mask - R/W Address Y45 is unmasked. This bit is cleared when either this
register, or the latched status register is read.
Bipolar Violation Error Counter Overflow Interrupt.
This bit is one when the corresponding
VEOL bit in the E1 Counter Latched Status - R Address Y25 is set, and the corresponding
VEOM bit in the E1 Counter Interrupt Mask - R/W Address Y45 is unmasked. This bit is cleared
when either this register, or the latched status register is read.
