&I n – Dial Transmit Level for Cellular Auto
When Dial Transmit Level Type is set to Permissive, &I n sets Dial Transmit Level to a value between –10 and – 32 dBm.
&I99 and &I100 cause the level to be varied automatically according to conditions for ETC operation. &J0 overrides this
command, and is the default for North America.
&I0 – 0 dBm
&I7 –7 dBm
&I8 –8 dBm
&I9 –9 dBm
&I10 –10 dBm
&I11 –11 dBm
&I12 –12 dBm
&I13 –13 dBm
&I14 –14 dBm
&I15 –15 dBm
&I16 –16 dBm (Set by &F5)
&I32 – 32 dBm
&I99 Valid only if ETC is installed. Automatically adjusted according to the ETC1.0 specification. Set by &F6. Use
only with remote modems set to &I99, and limit the data rate to 4800 bps (S41 = 5).
&I100 Valid only if ETC is installed. Automatically adjusted according to the ETC1.1 specification.
NOTE: The default and permitted settings of this option are country-dependent. See
&J n – Dial Transmit Type
Sets the power output level of the transmit signal over dial lines. The &I n command overrides the &J n command.
&J0 Permissive (–9 dBm). Valid only for North America.
&L n – Leased Mode
Sets the modem for 2-wire leased-line operation in Answer mode or in Originate mode.
&L0 Disables leased-line operation.
&L1 2-wire originate leased-line operation.
&L3 2-wire answer leased-line operation.
The &L command will cause the modem to reset before entering or exiting Leased-Line mode. Therefore, it must be
entered as the last command in an initialization string.
WARNING: Do not configure the modem for leased line operation if the modem is connected to the PSTN.
