Remote Node Configuration
This chapter covers remote node configuration.
20.1 Introduction to Remote Node Setup
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 ZyXEL Device to make a call automatically, i.e., Dial on Demand. The following
describes how to configure Menu 11.1 Remote Node Profile, Menu 11.2 - Remote Node
PPP Options, Menu 11.3 - Remote Node Network Layer Options and Menu 11.5 - Remote
Node Filter.

20.1.1 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 ZyXEL Device 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 us say 3 minutes. With minimum toll period, the ZyXEL Device will
try to use all the toll period. In the above case, the ZyXEL Device 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 ZyXEL Device is not always perfectly
synchronized with your telephone company, the ZyXEL Device 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.

20.2 Remote Node Profile Setup
To configure a remote node, follow these steps:
1 From the main menu, select menu option 11 to open Menu 11 Remote Node Setup.
2 When menu 11 appears as shown in the following figure, enter the number of the remote
node that you wish to configure.
