COMSPHERE 392xPlus Modems
Automode: Enable
Nxt Enable Disable System 85
This configuration option only appears when Dial Line Rate is configured for V.32 or V.34 families data rate.
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.
Autorate: Enable
Nxt Enable Disable StartAt48 StartAt96
This configuration option only appears when Dial Line Rate is configured for V.32 or V.34 families data rate.
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, and V.32 terbo connections and 33.6 and 2400 bps for
the V.34 family.
Start at 48 and Start at 96 – Set the maximum connect rate for V.32, V.32bis, and 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
This configuration option is ignored unless Dial Line Rate is 4800(V32b).
V.32bis Override. Activates the AT&T Paradyne Point-to-Point Diagnostic 2400 bps modulation. Allows the modem to
use a non-standard, point-to-point modulation capable of secondary channel diagnostics while running at 2400 bps.
NOTE: This configuration option must be the same in both the local and remote modems.
Dial Tx Level: Permissv(–9)
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 to –32 dBm, plus Permissive (–9 dBm). This configuration
option is locked in other some countries (the user cannot change the level).
NOTE: The factory default setting is country dependent. Default is Permissv(–9) in North America.
The AT command is &I n , where n is from 10 to 32 corresponding to –10 dBm to –32 dBm.
