Bit 0 = AUPC Communication Error
Bits 1-2 = Eb/No Status
0 = Eb/No is Invalid
1 = Eb/No is Valid
2 = Eb/No is Smaller Than Indicated Value

3 = Eb/No is Larger Than Indicated Value

Unsigned Binary Value Decimal Point Implied


Note: The following byte applies only if an asynchronous

interface card, IDR or IBS interface card is installed, and
the AUPC option is installed and the AUPC is enabled. If
not, ignore this byte.

0 = Daughter Card OK

1 = Daughter Card Faulted

The following byte applies only if an IDR or IBS interface

card is installed and the modem is in IDR mode. If not,
ignore this byte.

Bit 0 = Backward Alarm 1
Bit 1 = Backward Alarm 2
Bit 2 = Backward Alarm 3
Bit 3 = Backward Alarm 4
Bits 4 – 7 = Spare
(0 = Not Transmitted, 1 = Transmitted)

0 = Front Panel, 1 = Terminal, 2 = Computer

Bit 0 = Terrestrial Frame Lock Fault (all modes)
Bit 1 = Terrestrial Multiframe Lock Fault (PCM-30 and

PCM-30C only)
