Dial Line Configuration Options

Automode: Enable

Nxt Enable Disable System 85

Automode. Allows the modem to automatically detect the remote modem's modulation.

Enable ± The modem automatically adapts to the modulation scheme and line rate of the remote modem, and the VF line condition. However, the maximum data rate the modem uses is determined by the Dial Line Rate configuration option. Bell 103J protocol is used for data rates of 0±300 bps.

Disable ± Connection fails if the remote modem does not support the selected modulation.

System 85 ± Modifies parameters used by the connection process. Specify System 85 only if your modem is in a modem pool attached to a System 85 Private Branch Exchange (PBX).

The factory default is Enable.

AT command equivalent is S-register S78 = n.

Autorate: Enable

Nxt Enable Disable StartAt48 StartAt96

Autorate. Controls the modem's ability to adjust its speed upward and downward to accommodate the conditions of the VF line.

Enable ± 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, limited by the value of the Dial Line Rate configuration option. This autorating only occurs between 4800 bps and 19,200 bps during V.32bis and V.32terbo connections and between 2400 bps and 33,600 bps during V.34 connections.

Disable ± Line rate does not vary after the initial line rate selection during startup.

StartAt48, StartAt96 ± Useful for lines with known noise problems, these settings cause the modem to connect at 4800 bps (StartAt48) or 9600 bps (StartAt96). If line conditions warrant it, the modem shifts up to the next higher rate until the value of Dial Line Rate or the highest possible rate for the line is reached.

The factory default is Enable.

AT command for Autorate is S-register S76=n.
