Leased Line Configuration Options

V32bis Autorate: Enable

Nxt Enable Disable

This configuration option only appears when Leased Line Rate is configured for V.32 terbo or V.32bis 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.

The AT command is S-Register S82=n, where n is 0 for Enable and 1 for Disable.

V32bis Override: Disable

Nxt Disable 2400 1200

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

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

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

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

Leased Tx Level: The factory default setting is country dependent. It is 0 dBm in North America Nxt 0 ±1 ±2 ±3 ±4 ±5 ±6 ±7 ±8 ±9 ±10 ±11 ±12 ±13 ±14 ±15

Leased Transmit Level. Selects the modem's transmit power level over leased lines. The transmit output level can be selected in 1 dBm decrements from 0 dBm to ±15 dBm.

NOTE: The leased TX level is limited to ±1 dBm in all countries except North America.

The AT command is S-Register S45=n, where n is from 0 to 15 corresponding to 0 dBm to ±15 dBm.

Auto Dial Back: Disable

Nxt Disable Enable FastBackup

This configuration option is not available if the LeaseLine Rate is configured for TMp and the NetworkPosition is configured for Control.

Automatic Dial Backup. Allows the modem to dial the number stored in directory location 1 to restore communications with the remote modem when the leased lines fail.

NOTE: In point-to-point applications, this configuration option must be set to Enable in both the local and remote modem. The answering modem must have its Auto-Answer Ring Number configuration option enabled. Refer to the Line Dialer configuration option group for information regarding Auto-Answer.

NOTE: When this configuration option is enabled, the originating modem will attempt the dial backup for a maximum of 10 call attempts, with a 2-minute delay between calls. This function can be reset with a completed manual dial backup, a power cycle, or using NMS.

HFast Backup

Only used in special applications requiring a shortened delay time from the failure of the leased lines to the initiation of the automatic dial backup.

The AT command is S-Register S46=n, where n is 0 for Disable, 1 for Enable, and 2 for FastBackup.
