Taicom Data Systems Co Ltd AWL1000G User Manual

MRU: The MRU (Maximum Receive Unit) field indicates the maximum size IP packet that the
peer of PPP connection (this device) can receive. During the PPP negotiation, the peer of the PPP
connection will indicate its MRU and will accept any value up to that size.

Range: 0-32767

Default: 1492

MTU: Maximum Transmission Unit (MTU) is the largest size packet that can be sent by the
modem. If the network stack of any packet is larger than the MTU value, then the packet will be
fragmented before the transmission. During the PPP negotiation, the peer of the PPP connection
will indicate its MRU and will accept any value up to that size.

Range: 0-32767

Default: 1492

MSS: Maximum Segment Size is the largest size of data that TCP will send in a single,
unfragmented IP packet. The LAN client and the WAN host will indicate their MSS during the
TCP connection handshake.

Range: 0-32767

Default: 1432

Lcp Echo Interval: It is the time interval, in seconds, between PPP session connection attempts.

Range: 0-32767

Default: 10

Lcp Echo Maximum Consecutive Failure: It is the number of times a PPP session can fail
while trying to connect before stopping. If a PPP session fails this number of times, you must
manually reconnect the PPP session.

Range: 0-32767

Default: 6

Authentication: The different types of available authentications are:

Auto (default): When auto is selected, PAP mode will run by default. However, if PAP fails,

then CHAP will run as the secondary protocol. This is the default setting.

PAP: Password Authentication Procedure. Authentication is done through username and

password.

CHAP: Challenge-Handshake Authentication Protocol. Typically more secure than PAP,

CHAP uses username and password in combination with a randomly generated challenge
string which has to be authenticated using a one-way hashing function.

Automatic Reconnect: When it is checked, the Router will reconnect a PPP session when it is
terminated by the ISP. If a PPP session is terminated under any other conditions (i.e. by
Disconnect Timeout or manual disconnect), the Automatic Reconnect will not reconnect the
session. This box is unchecked by default.

PPP Configuration Status: A table will be displayed at the bottom of this page to show all
related information of PPP configuration.
