Understanding the Three Dial-in Scenarios
17
6
In the Idle Timer field, enter the length of inactivity before the LAN Modem drops
the incoming call. By default this value is 900 seconds (15 minutes).
7
In the ISP Selection field, select the service provider that this dial-in user can access
when dialing into the LAN Modem.
8
In the Data Compression field, choose to have data compression active or inactive.
By default compression is disabled. (In order for compression to occur, the other
end of the connection must have the same compression active.)
Callback Parameters
This section allows you to enable and configure callback functionality. Callback
occurs when, upon a successful connection of dial-in a user, the LAN Modem
drops the incoming call and places a return call to the dial-in user.
To specify your Callback parameters, do the following. In order for callback to
occur, the other end of the connection must support callback functionality and
have it enabled. For more information refer to “Callback Feature”.
1
In the Enable Callback field, check to activate Callback for this dial-in user. By
default Callback is disabled.
2
In the Callback Telephone Number field, enter the number the LAN Modem will
call back when this dial-in user accesses the LAN Modem, to verify the dial-in
user’s authenticity. Note that this value will override the telephone number
provided by the client, should the client provides a different number.
3
In the Callback Multilink Number field, enter a second ISDN telephone to be used
for either Multilink PPP or as a second number to try if the call cannot be
established with the first telephone number.
4
In the Callback Authentication field, check the box to require callback
authentication. Note that Callback Authentication is not required for callback
functionality, but provides a further level of security by confirming the server’s
authenticity to the dial-in user.
5
In the Callback Username and Password fields, enter the username and password
which the client will use to verify the server’s authenticity. If the dial-in client is a
LAN Modem, these values will match the username and password of the client
LAN Modem’s Callback Login and Password fields, located on the client LAN
Modem’s service provider parameters page.
6
In the B Channel Rate field, choose to use either 64 Kbps or 56 Kbps for the
connection. By default this field is set to 64 Kbps.
7
In the Callback Delay field, enter the amount of time in seconds to wait until the
dial-in user is called back. By default this is set to 5.
Caller ID Authentication Parameters
1
If you would like CLID Authentication (Calling Line ID) field, check the
Enable
box
which indicates that CLID authentication must be present for the callback to
continue. CLID authentication is used to verify the telephone number of the dial-in
client. If enabled, the dial-in client cannot call from any other telephone number
except the number specified in the Remote CLID field.
2
Remote CLID Phone Number 1: If you are requiring CLID authentication, enter the
first expected telephone number for this dial-in user.
