Chapter 22 Dial-in Setup

202

This chapter shows you how to configure your ZyXEL Device to receive calls from remote 
dial-in users including telecommuters and remote nodes. This is done in SMT menus 13 and 
14.

There are several differences between dial-in users and remote nodes, as summarized in the 
next table.

This section covers the default dial-in parameters. The parameters in menu 13 affect incoming 
calls from both remote dial-in users and remote nodes until authentication is completed. Once 
authentication is completed and if it matches a remote node, your ZyXEL Device will use the 
parameters from that particular remote node.

CLID (Calling Line IDentification) authentication affords you the security of limiting a user to 
only initiate connections from a fixed location. The ZyXEL Device uses the caller ID sent by 
the switch to match against the CLIDs in the database. Please note that for CLID 
authentication to work on the ZyXEL Device, your telephone company must support caller ID. 
If the remote node requires mutual authentication, please fill in the O/G Username and O/G 
Password fields. You must also fill in these fields when a dial-in user to whom we are calling 
back requests authentication. 

Table 70   Remote Dial-in Users/Remote Nodes Comparison Chart

Your ZyXEL Device will only answer calls from 

remote dial-in users; it will not make calls to 

them.

Your ZyXEL Device can make calls to and 

receive calls from the remote node.

All remote dial-in users share one common set 

of parameters, as defined in the Menu 14 

Default Dial-in User Setup.

Each remote node can have its own set of 

parameters such as Bandwidth On Demand, 

Protocol, Security, etc.
