Functional Description
7
EBI
Receive E-bit Interrupt. When unmasked an interrupt is initiated when a
(0)
receive E-bit indicates a remote CRC-4 error. 1 - unmasked, 0 - masked.
Interrupt vector = 00100000.
6
CRCI
CRC-4 Error Interrupt. When unmasked an interrupt is initiated when a
(0)
local CRC-4 error occurs. 1 - unmasked, 0 - masked. Interrupt vector =
00100000.
5
CEFI
Consecutively Errored FASs Interrupt. When unmasked an interrupt is
(0)
initiated when two consecutive errored frame alignment signals are
received. 1 - unmasked, 0 - masked. Interrupt vector = 00100000.
4
BPVI
Bipolar Violation Interrupt. When unmasked an interrupt is initiated when
(0)
a bipolar violation error occurs. 1 - unmasked, 0 - masked. Interrupt vector
= 00100000.
3
RCR0I
RAI and Continuous CRC Error Interrupt. When unmasked an interrupt
(0)
is initiated when the received A bit has been one, and the received E bits
have been zero, continuously for greater than 10 milliseconds (see page
04H, address 19H) 1- unmasked, 0 - masked. Interrupt vector = 00100000.
2
RCR1I
RAI and Continuous CRC Error Interrupt. When unmasked an interrupt
(0)
is initiated when the received A bit had been set, and the received E bits
were low, continuously for greater than 10 milliseconds, but less than 450
milliseconds (see page 04H, address 19H). 1 - unmasked, 0 - masked.
Interrupt vector = 00100000.
1
BERI
Bit Error Interrupt. When unmasked an interrupt is initiated when a bit
(0)
error occurs. 1 - unmasked, 0 - masked. Interrupt vector = 00100000.
0
SIGI
Signalling (CAS) Interrupt. When unmasked and any of the receive ABCD
(0)
bits of any channel changes state an interrupt is initiated. 1 - unmasked, 0 -
masked. Interrupt vector = 00000001
