When Dial Transmit Level Type is set to Permissive, &In 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.

&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 Appendix H.

&Jn ± Dial Transmit Type

Sets the power output level of the transmit signal over dial lines. The &In command overrides the &Jn command.

&J0 Permissive (±9 dBm). Valid only for North America.

&Ln ± 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.
