31.3.2.1 Outgoing Authentication Protocol
Generally speaking, you should employ the strongest authentication protocol possible, for
obvious reasons. However, some vendor’s implementation includes a specific authentication
protocol in the user profile. It will disconnect if the negotiated protocol is different from that in
the user profile, even when the negotiated protocol is stronger than specified. If you encounter
a case where the peer disconnects right after a successful authentication, please make sure that
you specify the correct authentication protocol when connecting to such an implementation.
31.3.2.2 Always-On Connection
An Always-On (nailed-up) connection is a dial-up line where the connection is always up
regardless of traffic demand. The LAN-Cell does two things when you specify an always-on
connection. The first is that idle timeout is disabled. The second is that the LAN-Cell will try
to bring up the connection when turned on and whenever the connection is down. An always-
on connection can be very expensive for obvious reasons.
Do not specify an always-on connection unless your telephone company offers flat-rate
service or you need a constant connection and the cost is of no concern.
The following table describes the fields not already described in Table 197 on page 466.
31.3.2.3 Metric
See Section on page 92 for details on the Metric field.
31.3.3 PPTP Encapsulation
If you change the Encapsulation to PPTP in menu 11.1, then you will see the next screen.
Table 198 Fields in Menu 11.1 (PPPoE Encapsulation Specific)
FIELD DESCRIPTION
Service Name If you are using PPPoE encapsulation, then type the name of your PPPoE service
here. Only valid with PPPoE encapsulation.
Authen This field sets the authentication protocol used for outgoing calls.
Options for this field are:
CHAP/PAP - Your LAN-Cell will accept either CHAP or PAP when requested by this
remote node.
CHAP - accept CHAP only.
PAP - accept PAP only.
Telco Option
Allocated
Budget
The field sets a ceiling for outgoing call time for this remote node. The default for this
field is 0 meaning no budget control.
Period(hr) This field is the time period that the budget should be reset. For example, if we are
allowed to call this remote node for a maximum of 10 minutes every hour, then the
Allocated Budget is (10 minutes) and the Period(hr) is 1 (hour).
Schedules You can apply up to four schedule sets here. For more details please refer to
Chapter 42 on page 563.
Always On
Connection
This field specifies if you want to make the connection to this remote node an always-
on connection. More details are given earlier in this section.
Session
Options
Idle Timeout Type the length of idle time (when there is no traffic from the LAN-Cell to the remote
node) in seconds that can elapse before the LAN-Cell automatically disconnects the
PPPoE connection. This option only applies when the LAN-Cell initiates the call.
