T1 Transceiver 1 Receive Interrupt.
When any bit in the T1 Transceiver 1 - T1 Receive Line and
Timer Interrupt Status - R Address Y35 (Y=1) is set to one, this status bit is one; otherwise, it is
zero. The corresponding bit in the T1 Interrupt Vector Mask - R/W Address 902 must be unmasked
for this operation to function.
T1 Transceiver 1 Sync Interrupt.
When any bit in the T1 Transceiver 1 - T1 Receive and Sync
Interrupt Status - R Address Y34 (Y=1) is set to one, this status bit is one; otherwise, it is zero. The
corresponding bit in the T1 Interrupt Vector Mask - R/W Address 902 must be unmasked for this
operation to function.
T1 Transceiver 0 HDLC Interrupt.
When any bit in the T1 Transceiver 0 - T1 & E1 HDLC Interrupt
Status - R Address Y33 (Y=0) is set to one, this status bit is one; otherwise, it is zero. The
corresponding bit in the T1 Interrupt Vector Mask - R/W Address 902 must be unmasked for this
operation to function.
T1 Transceiver 0 Elastic Interrupt.
When any bit in the T1 Transceiver 0 - T1 Elastic Store
Interrupt Status - R Address Y36 (Y=0) is set to one, this status bit is one; otherwise, it is zero. The
corresponding bit in the T1 Interrupt Vector Mask - R/W Address 902 must be unmasked for this
operation to function.
T1 Transceiver 0 Receive Interrupt.
When any bit in the T1 Transceiver 0 - T1 Receive Line and
Timer Interrupt Status - R Address Y35 (Y=0) is set to one, this status bit is one; otherwise, it is
zero. The corresponding bit in the T1 Interrupt Vector Mask - R/W Address 902 must be unmasked
for this operation to function.
T1 Transceiver 0 Sync Interrupt.
When any bit in the T1 Transceiver 0 - T1 Receive and Sync
Interrupt Status - R Address Y34 (Y=0) is set to one, this status bit is one; otherwise, it is zero. The
corresponding bit in the T1 Interrupt Vector Mask - R/W Address 902 must be unmasked for this
operation to function.

E1 Transceiver 3 HDLC Interrupt.
When any bit in the E1 Transceiver 3 - T1 & E1 HDLC Interrupt
Status - R Address Y33 (Y=3) is set to one, this status bit is one; otherwise, it is zero. The
corresponding bit in the E1 Interrupt Vector Mask - R/W Address 902 must be unmasked for this
operation to function.
E1 Transceiver 3 National Interrupt.
When any bit in the E1 Transceiver 3 - E1 National Interrupt
Status - R Address Y36 (Y=3) is set to one, this status bit is one; otherwise, it is zero. The
corresponding bit in the E1 Interrupt Vector Mask - R/W Address 902 must be unmasked for this
operation to function.
E1 Transceiver 3 Counter Interrupt.
When any bit in the E1 Transceiver 3 - E1 Counter Interrupt
Status - R Address Y35 (Y=3) is set to one, this status bit is one; otherwise, it is zero. The
corresponding bit in the E1 Interrupt Vector Mask - R/W Address 902 must be unmasked for this
operation to function.
E1 Transceiver 3 Sync Interrupt.
When any bit in the E1 Transceiver 3 - E1 Sync Interrupt Status
- R Address Y34 (Y=3) is set to one, this status bit is one; otherwise, it is zero. The corresponding
bit in the E1 Interrupt Vector Mask - R/W Address 902 must be unmasked for this operation to
function.
E1 Transceiver 2 HDLC Interrupt.
When any bit in the E1 Transceiver 2 - T1 & E1 HDLC Interrupt
Status - R Address Y33 (Y=2) is set to one, this status bit is one; otherwise, it is zero. The
corresponding bit in the E1 Interrupt Vector Mask - R/W Address 902 must be unmasked for this
operation to function.
