Remote Control Operation

MN/SLM3650.IOM

A–21

Recall
Modem
Config.

Command:
Response:

<add/RMC_n'cr'
>add/RMC_n'cr''lf']

Where: n = 1, 2, 3, 4, or 5 (stored configuration number).

This command causes the modem to be reprogrammed with
configuration parameters previously saved using the 'SMC_'
command. One of five saved configurations can be specified.

Local Modem
AUPC Mode

Command:
Response:

Status:
Response:

<add/LMA_xxx'cr'
>add/LMA_xxx'cr''lf']

<add/LMA_'cr'
>add/LMA_xxx'cr''lf']

Where: xxx = ON or OFF.

This command configures the modem for the LOCAL MODEM
AUPC mode. When 'ON' is selected, the AUPC configuration can
be entered.

RTS TX-IF
Control Mode

Command:
Response:

Status:
Response:

<add/RTSM_xxx'cr'
>add/RTSM_xxx'cr''lf']

<add/RTSM_'cr'
>add/RTSM_xxx'cr''lf']

Where: xxx = ON or OFF.

This command configures the modem for the RTS TX-IF control
mode. If 'ON' is selected, the TX-IF output will only be turned on if
the incoming RTS signal is asserted (also the TX-IF output has to
be programmed ON and no major modulator faults are present). If
'OFF' is selected, the TX-IF output will operate normal ignoring
the RTS signal.

RF Mode
Control

Command:
Response:

Status:
Response:

<add/RFMD_xxxx'cr'
>add/RFMD_xxxx'cr''lf']

<add/RFMD_xxxx'cr'
>add/RFMD_xxxx'cr''lf']

Where: xxxx = NRM (Normal Mode), PWR (Turn RF off on power
up), COMM (Turn RF off on power up and loss of remote
communications after 10 seconds), CD (Turn RF ON when carrier
is detected, turn RF OFF when no carrier is detected. For the RF
ON condition, the TX-IF must be programmed ON. Note: RTS
TX-IF, when enabled over-rides CD).

This command allows for the RF output to be enabled or disabled
depending on the following described conditions. One application
for this command will be in demand network systems.

G.703 Line
Termination

Command:
Response:

Status:
Response

<add/G7LT_xxxxx'cr'
>add/G7LT_xxxxx'cr''lf']

<add/G7LT_'cr'
>add/G7LT_xxxxx'cr''lf']

Where: xxxxx = UNBAL (Unbalanced) or BAL (Balanced)

Note: Data is only returned if G.703 Personality PCB is installed.

Built In Self
Test

Command:
Response:






Status:
Response:

<add/BIST_xxxx'cr'
for (OFF or AUTO):
>add/BIST_xxxx'cr''lf']

for (RUN):
>add/BIST_xxxx'cr'
ST_xxx'cr''lf']

<add/BIST_xxxx'cr'
>add/BIST_xxxx'cr''lf']

Where: xxxx = OFF (self test disabled), RUN (run self test now),
AUTO (run self test on power up/software restart).




Self Test (OK/FLT)

Note: Allow 35 Seconds for response to RUN the Self Test.
