Synchronization Interrupt. When unmasked (SYNI = 0) an interrupt is
initiated when a loss of basic frame synchronization condition exists.
Interrupt vector = 10000000.
Remote Alarm Indication Interrupt. When unmasked (RAII = 0) a
received RAI will initiate an interrupt. Interrupt vector = 01000000.
Alarm Indication Signal Interrupt. When unmasked (AISI = 0) a received
AIS will initiate an interrupt. Interrupt vector = 01000000.
Channel 16 Alarm Indication Signal Interrupt. When unmasked (AIS16I
= 0), a received AIS16 will initiate an interrupt. Interrupt vector =
01000000.
Loss of Signal Interrupt. When unmasked (LOSI = 0) an interrupt is
initiated when a loss of signal condition exists. Interrupt vector =
01000000.
Frame Error Interrupt. When unmasked (FERI = 0), an interrupt is
initiated when an error in the frame alignment signal occurs. Interrupt
vector = 00100000.
Bipolar Violation Counter Overflow Interrupt. When unmasked (BPVO
= 0), an interrupt is initiated when the bipolar violation error counter
changes form FFFFH to 0H. Interrupt vector = 00010000.
SLIP Interrupt. When unmasked (SLPI = 0), an interrupt is initiated when
a controlled frame slip occurs. Interrupt vector = 00000100.
