Dial Transmit Level. Sets the power output level of the transmit signal over dial lines.

Permissive (±9 dBm) ± The modem transmits data at approximately ±9 dBm. This is true whether the modem is connected to an RJ11-type permissive jack or to an RJ41 or RJ45 programmable jack.

ETC 1.0_Cell ± Transmit level is automatically adjusted in response to line conditions according to the proprietary Enhanced Throughput Cellular (ETCt) 1.0 specification. Use only with remote modems set to ETC 1.0_Cell, and limit the data rate to 4800 bps.

ETC 1.1_Cell ± Transmit level is automatically adjusted in response to line conditions according to the proprietary Enhanced Throughput Cellular 1.1 specification.

The factory default is Permissv(±9).

AT command equivalent s are &In and &Jn.

V22b Guard Tone: Disable

Nxt Disable 550Hz 1800Hz

V.22bis Guard Tone. Determines whether the V.22bis guard tone is disabled, set to 550 Hz, or set to 1800 Hz.

Disable ± No guard tone.

550 Hz or 1800 Hz ± When the modem is in Answer mode, it transmits the guard tone at this frequency.

The factory default is Disable.

AT command equivalent is &Gn.

Train Time: Long

Nxt Long Short

Train Time. Controls V.34, V.32terbo, V.32bis, and V.32 train. Determines whether minimum or maximum time durations are used during the handshaking sequence for both dial and leased line applications.

NOTE: This configuration option only appears when the Dial Line Rate configuration option is set for V.34, V.32terbo, V.32bis, or V.32.

Long ± Selects long train. Use this setting whenever far-end frequency offset (phase roll) may be encountered. This is usually only required when transmitting over satellite links.

Short ± Allows the modem to train-up faster.

The factory default is Long.

AT command equivalent is S-register S43=n.
