5.3.4. PPPoE
Settings for the connection used Point-to Point Protocol over the Ethernet.
PPPoE is a protocol for encapsulating the PPP link over Ethernet, thus providing the benefits of PPP,
such as security (encryption) and control of connection (data rate) over an 802.3 network.
It is used for broadband Internet connections, such as DSL or ADSL, thus it is useful when the WAN
connection of Bytton LTE is achieved by a cable or ADSL modem instead of the HSDPA network.

Settings are the same as for “normal” PPP, except that the modem-related parameters and command
strings are missing here.
Username
: The user name used for log-in to the Internet account supplied by your ISP. Ask your Internet
provider for details! Some Internet providers need the complete account name together with the hosting
domain, the same as for an e-mail address:
, while other ISPs require that you type
here just the name of your account.
Password
: The password used for authenticating to your Internet account.
Redial Period
: time in seconds until redialing a connection, if it was broken, such as 5 seconds.
Idle Time
: Bytton LTE can disable the connection when there is no more data traffic. If no data packet is
sent through the interface for a specified period of time, the Internet connection will be broken. This is
useful in case of connections where you pay per connected time.
You can specify this time interval, in seconds.
When the interval is too short, even a momentary lack of activity (no data traffic) will cause the Internet
connection to be interrupted.
If you set the time interval to 0 (zero), the connection will remain always on, even if there is no data traffic
on the remote interface.
This feature is especially important for connections where you are charged for the total connection
time, no matter the data traffic: to avoid unnecessary expenses, you should set BYTTON to disconnect
when there is no data traffic.
MTU
: value for the Maximum Transmission Unit. MTU is the largest physical packet size, measured in
bytes, which a network can transmit. Messages larger than this will be fragmented into several packets.
Different networks have different values for MTU, which is set by the network administrator.
It is important to set the optimal MTU value, if it is incorrectly set the data transfers will be slow.
The default MTU size is 576 for many PPP connections, 1024 for a modem connection, 1500 for Ethernet
networks, etc. The same applies for MRU (maximum
receive
unit).
