Configuring Modems for Restoral
You can configure the modem to automatically respond to deteriorating
leased-line conditions by switching operation to a back-up dial line.
For further details on the parameter options listed here, refer to the 3460
Fast’R Reference Guide (part no. T0022).
If you normally operate the modem on a leased line, you can set the
following options to enable it to switch operation to a backup dial line
when conditions warrant. The following example shows the default
options.
Parameter Option Comment
Answer Restoral AT * AS0=LL Fail
Answering modem:
When connected to the leased
line, the modem answers a dial
call only if the leased line fails.
This parameter does not apply
when AT*RE=0 (Off).
Lease to Dial
Threshold AT * DI1=Low/Fast The originating modem uses this
option to determine the threshold
for initiating restoral. Low/Fast is
the most sensitive option–if three
retrains occur within five
minutes, the modem initiates
restoral.
Hold Dial Line AT * HD0=Off The originating modem uses the
HD option to determine how to
hold a dial connection while
testing a leased line. Off means
that the modem disconnects from
the dial line as soon as it connects
to the leased line.
This parameter works only when
the Initiate/Terminate Restoral
parameter (*RE) is set to
NM/Fast’RVu/Auto (option 4).
Parameters and options shown shaded gray vary by country. For details, refer
to Appendix B of the 3460 Fast’R Reference Guide.
