&In Dial Transmit Level for Cellular Auto

When Dial Transmit Level Type is set to Permissive, &In sets Dial Transmit Level to a value between ±10 and ±32 dBm. If Enhanced Throughput Cellular (ETC) is installed, &I99 and &I100 causes the level to be varied automatically according to conditions for ETC operation. &J0 overrides this command.

&I10 ±10 dBm &I11 ±11 dBm

&I32 ±32 dBm

&I99 Valid only if ETC is installed. Dial Transmit Level is automatically adjusted according to the ETC1.0 specification. 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. Dial Transmit Level is automatically adjusted according to the ETC1.1 specification. Set by &F6.

&Jn Dial Transmit Type

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

&L0 Disables leased-line operation.
