G.6.4.5.14 Bulk Consolidated Analog Status
This command is similar to the "BCS_" command, but returns MODEM analog parameters.
Command:
Response:
Note: Parameters 1 through 4 are dependent on carrier acquisition. If the decoder is not
locked, empty data blocks are returned (,,,).
G.6.4.5.15 Bulk Consolidated Status Faults
This command causes all modem fault status to be returned. To reduce the length of the
response, fault status is embedded into the bit structure of the characters that are returned.
Faults are indicated by a binary 1 in the designated bit position.
Command:
Response:
G–42

Where: pn =
Parameter 1 (p1): Receive signal level.
p1 = -nn, where "nn" is the value of the receive signal level in dBm.
Parameter 2 (p2): Raw BER.
p2 = nnnnE-4, where "nnnn" is the raw bit errors in 10000 bits.
Parameter 3 (p3): Corrected BER.
p3 = nE-e, where "n" is the mantissa and "e" is exponent (power of 10).
Parameter 4 (p4): EB/N0.
p4 = n.n, where "n.n" is E

Character "a": Modulator fault status character 1.
Bit 6 = 1 always.
Bit 5 = Modulator fault.
Bit 4 = RF output status, actual not programmed status
(1 = on, 0 = off).
Bit 3 through Bit 0 = Binary representation (0 to 10) of the
number of modulator stored faults.
Character "b": Modulator fault status character 2.
Bit 6 = 1 always.
Bit 5 = AGC fault.
Bit 4 = Modulator RF synthesizer fault.
Bit 3 = Bit clock fault.
Bit 2 = Transmit clock fault.
Bit 1 = I-channel fault.
Bit 0 = Q-channel fault.
