Leased Line Configuration Options

AutoDialStandby: Disable

Nxt Disable 15min 30min 1hr 4hr Test(2min) Adv15min Adv30min Adv1hr AdvTest2min

Automatic Dial Standby. Permits a modem operating on dial lines (regardless of the method of dialing origination) to check the quality of the leased lines periodically and, if they are good, to disconnect from the dial lines and resume operations on the leased lines.

This configuration option is not available on the Model 3820.

The time interval that the modem uses to check the quality of the leased lines is determined by the configuration option. These intervals are 15 minutes, 1 hour, and 4 hours.

The normal settings cause a lapse of data flow on the dial line while the leased-line connection is checked. The Advanced settings allow data flow to continue without interruption while the leased line is evaluated. If Advanced settings are used, then both modems must be configured to the same Advanced setting.

The Test(2min) selections are for testing this feature only.

The factory default is Disable.

AT command is S-register S47 = n :

S47 = 0	Disable
S47 = 1	15min
S47 = 2	1hr
S47 = 3	4hrs
S47 = 4	Test(2min)
S47 = 5	Advanced 15min
S47 = 6	Advanced 1hr
S47 = 7	Advanced 4hrs
S47 = 8	Advanced Test(2min)

CarrierOn Level: ± 43dbm

Nxt ± 43dbm ±26dbm

Carrier On Level. This configuration option controls the carrier detection threshold for leased lines. When the power level of the receive carrier signal drops 2 dBm below this level (either ±26 dBm or ±43 dBm), LSD turns Off. When the carrier signal is greater than this level, LSD turns ON.

The factory default is ±43dbm.

AT command is S-register S48 = n, where n is 0 for ±43 dBm or 1 for ±26 dBm.

FallFwdDelay: Disable

End Disable 5_mins 15_mins 1_hour

Fall Forward Delay. Provides an initial delay before leased or dial lines are monitored for fall forward conditions. After the timer expires, monitoring occurs as usual. Possible delay times are 5 minutes, 15 minutes, or 1 hour.

The factory default is Disable (no delay).

NOTE: Fall Forward Delay appears under both the Dial Line configuration options and the Leased Line configuration options, but the same setting is used for both. Changing it in one place effectively changes it in the other.

There is no analogous AT command, so this configuration option is not available for modems without a shared or integral DCP.
