Dial Line Configuration Options

V32bis Automode: Enable
Nxt Enable Disable System 85

This configuration option only appears when Dial Line Rate is configured for V.32 terbo, V.32bis, or
V.32 data rate.

V.32bis Automode. The modem automatically adapts to the modulation scheme and line rate of the remote
modem. However, the maximum data rate the modem uses is determined by the Dial Line Rate
configuration option.

System 85

Enables the full automode function with special provisions which are needed to work reliably in a
System 85 or similar PBX modem pool.

NOTE: When the V.32bis Automoding configuration option is enabled, the V.21 protocol (0–300 bps) is

excluded from the Automoding sequence. Instead, the modem uses the Bell 103J protocol for
0–300 bps operation.

The AT command is S-Register S78=

n, where n is 0 for Enable, 1 for Disable, and 2 for System 85.

V32bis Autorate: Enable
Nxt Enable Disable StartAt48 StartAt96

This configuration option only appears when Dial Line Rate is configured for V.32 terbo, V.32bis, or
V.32 data rate.

V.32bis Autorate. Once connected, the modem automatically lowers the line rate if line conditions become
impaired. When line conditions improve, the modem automatically shifts up to the highest data rate the line
can support. This autorating only occurs between 19,200 bps and 4800 bps during V.32/V.32bis/V.32 terbo
connections.

Start at 48 and Start at 96

Set the maximum connect rate for V.32/V.32bis/V.32 terbo connections.

The AT command is S-Register S76=

n, where n is 0 for Enable, 1 for Disable, 2 for Start at 48, and 3 for

Start at 96.

V32bis Override: Disable
Nxt Disable 2400 1200

This configuration option is ignored unless Dial Line Rate is 4800(V32b).

V.32bis Override. Activates the Paradyne Point-to-Point Diagnostic 2400 bps or 1200 bps modulation.
Allows the modem to use a non-standard, point-to-point modulation capable of secondary channel
diagnostics while running at 2400 bps or 1200 bps.

NOTE: This configuration option must be the same in both the local and remote modems.

NOTE: The 1200 bps selection is available only if the Proprietary 1200 device option is installed.

Dial TX Level: The factory default setting is country dependent. It is Permissv(–9) in North America
Nxt Permissv(–9) –10 –11 –12 –13 –14 –15 –16 –17 –18 –19 –20 –21 –22 –23 –24 –25 –26
–27 –28 –29 –30 –31 –32

Dial Transmit Level. Selects the modem’s transmit power level over dial lines. The transmit output level can
be selected in 1 dBm decrements from –9 dBm to –32 dBm.

NOTE: In North America the range of allowable values is –10 dBm to –32 dBm, plus Permissive (–9 dBm).

This configuration option is locked in other countries (the user cannot change the level).

The AT command is &

n, where n is from 10 to 32 corresponding to –10 dBm to –32 dBm.
