Remote Node Configuration
A remote node is required for placing calls to a remote gateway. A remote node represents both the remote
gateway and the network behind it across a WAN connection. Note that when you use Menu 4 to set up
Internet access, you are actually configuring one of the remote nodes. Once a remote node is configured
correctly, traffic to the remote network will trigger your Prestige to make a call automatically, i.e., Dial On
Demand.

In this chapter, we will discuss the parameters that are protocol independent. The protocol-dependent

5.1 Remote Node Setup
This section describes the protocol-independent parameters for a remote node.
5.1.1
Minimum Toll Period
Phone calls are normally charged per basic time unit with the time being rounded up to the nearest unit
when bills are calculated. For example, the Prestige may make a call but drop the call after 10 seconds
(maybe there was no reply) but the call would still be charged at a minimum time unit, let’s say 3 minutes.
With minimum toll period, the Prestige will try to use all the toll period. In the above case, the Prestige
tries to extend the idle timeout to the nearest 3 minutes (basic charging unit of time). If there is traffic
during the extended 2 minutes and 50 seconds, the idle timeout will be cleared and a second call is
eliminated. Since the session time calculation by the Prestige is not always perfectly synchronized with
your telephone company, the Prestige drops the channel 5 seconds before the toll period you set, to
compensate for any lag. As such, you must not set the minimum toll period to less than 5 seconds.
