-12 V, Implied Decimal Point and Minus Sign (ex: 118 =
-11.8 V)
Degrees C, Implied Decimal Point (ex: 490 = 49.0 °C)
Temperature is measured at the output amplifier, and does
not represent the overall internal temperature
Ignore These Bytes
Note: The following byte applies only if an asynchronous
interface card or an IDR or IBS interface card is installed,
and the AUPC option is installed and the AUPC is
enabled. If not, ignore this byte.
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)
Note: The following two bytes apply only if an
asynchronous interface card or an IDR or IBS interface
card is installed, and the AUPC option is installed and the
AUPC is enabled. If not, ignore Note: The following two
bytes.
Unsigned Binary Value, Decimal Point Implied
Note: The following byte applies only if an IDR or IBS
interface card is installed. If not, ignore this byte.
0 = Daughter Card OK, 1 = Daughter Card Faulted
Note: The following byte applies only if an IDR OR IBS
interface card is installed and the modem is in IDR mode.
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)
Bit 2 = Terrestrial CRC Lock Fault (PCM-30C and PCM-31C
