>add/MINP_snn.n'cr''lf']
>add/MINP_snn.n'cr''lf']

Where: snn.n = -30.0 to -5.0, in 0.1 steps (nominal range
in dBm).

Notes:

1. The nominal power range is modified relative to

the value specified by the modulator power offset
(MPO_).

2. ASYNC or AUPC Overhead only.

Where: nn.n = 3.2 to 16.0, in 0.1 increments (Eb/N0 in
dB).

Note: ASYNC or AUPC Overhead only.

Command:
Response:
Status:
Response:

>add/MAXT_n.n'cr''lf']

Where: n.n = 0.5 to 6.0, in 0.5 increments (max tracking
rate in dBm/minute).

Note: ASYNC or AUPC Overhead only.

AUPC Local
Carrier Loss
Action

Command:
Response:
Status:
Response:

>add/LCL_xxxx'cr''lf']

AUPC
Remote
Carrier Loss
Action

Command:
Response:

Where: xxxx = HOLD, NOM, or MAX (power level setting
when remote carrier loss).

Note: ASYNC or AUPC Overhead only.

Remote
Modem
AUPC
Commands

Notes:

1. Always wait 3 seconds between consecutive remote modem command/status polls.
2. If Local AUPC is not enabled, status commands will return last known condition. They will also request status

from the remote modem. This allows a second request to return proper status.

Remote
AUPC

Command:
Response:

>add/RPC_xxx'cr''lf'

Where: xxx = ON or OFF (remote AUPC enable).

Note: ASYNC or AUPC Overhead only.

Command:
Response:
Status:
Response:

>add/RISP_xxx'cr''lf']
>add/RISP_xxx'cr''lf']

Where: xxx = ON or OFF (remote transmit 2047 pattern
enable).

Notes:

1. Transmit 2047 Pattern.
2. ASYNC or AUPC Overhead only.

Loopback

Command:
Response:
Status:
Response:

Command:
Response:
Example:
Command:
Response:

>add/RRES_nE-e'cr''lf']

>add/RRES_2E-6'cr''lf']

Where:

n = 1 to 9 (error rate number).
e = 2 to 6 (exponent).

Notes:

1. Received 2047 Pattern.
2. AYNC or AUPC Overhead only.

This command returns 2047 BER from the remote AUPC
modem. If data is not valid, the message 'No_Data' is
returned in lieu of BER data.
