INTRODUCTION
The Multimessage M406 is an ADSL Ethernet Router. It is optimized
to address the growing demand for high-speed Internet access. With
an IEEE 802.3-compliant Ethernet interface, it provides connectivity
options without relying on host PC drivers.
The ADSL Ethernet Router is an "always-on" high-speed broadband
connection to the internet. Using existing twisted-pair telephone lines,
ADSL technology provides data rates more than 100 times as fast as a
traditional analogue modem, without an interruption in telephone service.
The ADSL Ethernet Router is fully compliant with the full-rate ADSL
(T1.413 Issue 2 and G.dmt) and the splitter less G.lite (G.992.2)
standards. With data transfer rates of up to 8 Mbps downstream and
1 Mbps upstream.

INSTALLATION
The M406 should already be fitted into the M400 chassis by an installation engineer. If the M406 has not been installed please follow the installation guide supplied with the unit.
Installation of ADSL Line
• The incoming ADSL line from your service provider should be
plugged into the ADSL line connector (see product illustration
P5).
Installation of Ethernet
• Plug your Ethernet cable from the Ethernet connector on the
M406 (P5) to a spare connector on your 10/100 Ethernet Switch
(M402).
• If you don’t have an M402 then your Ethernet cable needs to be
patched via the patch panel to the required computer. Follow the
procedure below.
• Select a socket in the room required to connect the computer to.
Note down the number on the socket.
• On the patch panel, link the corresponding numbered socket on
the patch side to the Ethernet connector on the M406, using the
appropriate coloured patch lead.
• Connect the computer’s Ethernet adaptor to the allocated room
socket, then power up the computer.
• Check on the M406 that the link indicator for the port being used
shows there is a connection.
• If the indicator shows that there is a link the network connection is
ready for use.

Test ADSL Synchronization: This test checks the ADSL Showtime. If
this test returns FAIL, all other tests will be skipped.
Test ATM OAM Segment Loop Back: This test sends ATM OAM F5
Segment loop back request cells to the CO. This test will pass if a
response cell is received. Since some service providers might not
Support this test, it could still work even if this test fails. If this test fails
consistently and the ADSL modem seems not to be working, make
sure the VPI and VCI are configured correctly.
Test ATM OAM End-to-End Loop Back: This test sends ATM OAM F5
End to End loop back request cells to the CO. This test will pass if a response cell is received. Since some service providers might not support this
test, it could still work even if this test fails. If this test return FAIL consistently and the ADSL modem seems not working, make sure the VPI and VCI
are configured correctly.
Test Ethernet Connect to ATM: This test checks that the ATM AAL5 mod-
ule is loaded correctly.
Test PPPoE Connection: This test checks the PPPOE connection.
Test PPP Layer Connection: This test checks the PPP authentication.

forward this packet to the DMZ host.
DMZ Host IP: The IP address of the DMZ host at LAN side.
DHCP Relay: If it is enabled, the DHCP requests from local PCs will
forward to the DHCP server runs on the WAN side. To have this function working properly, disable the NAT to run on router mode only, disable the DHCP server on the LAN port, and make sure the routing
table has the correct routing entry.
DHCP Target IP: The DHCP server runs on the WAN side.
IGMP Proxy: This is the global setting for IGMP Proxy. If it is enabled,
then the enabled IGMP Proxy on WAN PVCs will be working. Otherwise,
no WAN PVC can have IGMP Proxy working on it.
PPP reconnect on WAN access: If it is enabled, the PPP session will
be automatically established when there is a packet wants to go out the
WAN.
For the PPP connect on WAN access, the PPP will be automatically
reconnected when an URL is entered in the browser. For the Automatic
Reconnect, it will reconnect the PPP session whenever it is terminated
by ISP.
PPP Half Bridge: When the PPP Half Bridge is enabled, only one PC is
able to access the internet, and the DHCP server will duplicate the
WAN IP address from the ISP to the local client PC. Only the PC with
the WAN IP address can access the internet.
Reset to Factory Default
The Reset to Factory Default page allows users to reset the modem
to the original factory default configuration (factory reg).

There are four DNS proxy modes available.
• Disable DNS Proxy: The LAN port does not process the DNS query
message. For the DHCP requests from local PCs, the DHCP server
will set the user-configured preferred DNS server or alternate DNS
server whichever is available as the DNS server. All DNS query
messages will then be directly sent to the DNS servers.
• Use Auto Discovered DNS Servers Only: The DNS proxy will
store the DNS server IP addresses obtained from the DHCP client
or PPP into the table. All DNS query messages will be sent to one of
the dynamically obtained DNS servers.
• Use User Configured DNS Servers Only: The DNS proxy will use
the user-configured preferred DNS server and alternate DNS
server. All DNS query message will be sent to one of the DNS servers.
• Auto Discovery + User Configured: The DNS proxy's table has all
the IP addresses of dynamically obtained and user configured DNS
servers.

PPP
The router supports multiple PPP sessions per PVC. The PPP configuration in the WAN configuration page is for the first PPP session for e ach
PVC. The predefined PPP Account Name (Account ID) is "Simple
PPP Account 0" for PVCO and predefined PPP Connection Name is
"Simple PPP Session 0" for PVCO. For the other PVC X, the predefined account name and connection name will be Simple PPP Account X and Simple PPP Session X. X is the PVC number from 1 to 7.
It can support up to a total of 16 PPP sessions, and each PVC can
support up to 8 PPP sessions. The multiple PPP sessions may be
configured with any combination over 8 PVCs.
For the multiple PPP sessions, please go to PPP Configuration page.
Service Name: The service name of PPP is required by some ISPs.
If the ISP does not provide the service name, please leave it blank.
Disconnect Timeout: The Disconnect Timeout allows the users to set the
specific period of time to disconnect from the ISP. The default is 0,
which means never disconnect from the ISP.
MRU: Maximum Receive Unit indicates the peer of PPP connection the
maximum size of the PPP information field this device can be received.
The default value is 1492 and is used in the beginning of the PPP
negotiation. In the normal negotiation, the peer will accept this MRU
and will not send a packet with an information field larger than this
value.
MTU: Maximum Transmission Unit indicates the network stack of
any packet that is larger than this value will be fragmented before
the transmission. During the PPP negotiation, the peer of the PPP
connection will indicate its MRU and will be accepted. The actual MTU of
Page 22
22
the PPP connection will be set to the smaller one of MTU and the
Peer's MRU. The default value is 1492.
MSS: Maximum Segment Size is the largest size of data that TCP will send
in a single IP packet. When a connection is established between a LAN client and a host in the WAN side, the LAN client and the WAN host will
indicate their MSS during the TCP connection handshake. The default
value is 1432.
Automatic Reconnect: When it is checked, it will maintain the PPP connection all the time. If the ISP shuts down the PPP connection, it will automatically reconnect PPP session.
Authentication: When AUTO option is chosen, the PAP mode will run first
then CHAP.
Host Name: Required by some ISPs. If the ISP does not provide the host
name, please leave it blank.
IGMP
IGMP relay/proxy specification and environment:
• Support IGMP proxy/relay function for ADSL modem, based on the
following requirement and case.
• On CO side, there must be at least one IGMP querier (router) present. IGMP querier will send IGMP query packet. The ADSL modem
is responsible to relay these IGMP query to Ethernet.
• End-user multicast application device sends IGMP report while re-
ceiving IGMP query or being activated by user, the ADSL modem
should be responsible to proxy (that is, change source IP to ADSL
modem's WAN IP) the IGMP report to ADSL WAN side, include all
PVCs. The same case is for IGMP leave packet.

LAN and multiple WAN connections, and the LAN traffic is routed to
the appropriate WAN connections based on the destination IP addresses and Route Table. This eliminates the need for the static NAT
session configuration between multiple LAN clients and multiple
WAN connections.
When the Dynamic NAPT is chosen, there is no need to configure the
NAT Session and NAT Session Name Configuration.
NAT (Static): The NAT option only maps single WAN IP address
to the local PC IP address. It is peer-to-peer mapping. (1x1) For
each WAN interface, only one local PC IP address can be associated with each WAN interface. Click the link Session Name Configuration to add the session name for WAN interface.
Session Name: This field allows the user to enter his/her own session Name to distinguish different NAT session for different interfaces among different PPP sessions and different PVCs.
Interface: This field allows the user to choose specific WAN Interface (PVC
or PPP Session) for NAT Session.
NAT Session Name Status will be displayed at the bottom of this
page to show all the Session Names with its WAN Interface.
Click the link Go back to NAT Configuration to the NAT configuration
page. Select the NAT option. Input the session name and the PC IP
address, and choose the Add action. Click the Submit button and go to
the Save Settings to save this configuration.

manually assign an IP address and subnet mask for each PC on t he L A N,
or you can instruct the router to automatically assign them using
DHCP. The DHCP function is active by default.
PPP Configuration
The PPP Configuration page allows the user to configure multiple PPP
sessions for each PVC. It can support up to a total of 16 PPP sessions, and
each PVC can support up to 8 PPP sessions. The multiple PPP sessions
may be configured with any combination over 8 PVCs. To configure the
PPP, must go to the PPP Account Configuration page first to configure Account ID, Users Name and Password.

Account ID: This field allows the user to enter his/her own account ID to
distinguish different accounts.
User Name: Enter the PPP user name (usually provided by the ISP).
Password: Enter the PPP password (usually provided by the ISP).
PPP Account Configuration Status will be displayed at the bottom of
this page to show all the accounts with its Account Name and User
Name. (It does not show the password.)
Session Name: This field allows the user to enter his/her own session
name to distinguish different sessions for different PPP accounts and
different PVCs.
PVC: This field allows the user to choose the specific PVC for the
PPP session.
Service Name: The service name of PPP is required by some ISPs. If
the ISP does not provide the service name, please leave it blank.
Disconnect Timeout: The Disconnect Timeout allows the user to set
the specific period of time to disconnect from the ISP. The default is 0,
which means never disconnect from the ISP.
MRU: Maximum Receive Unit indicates for the PPP connection the maximum size of the PPP information field this device can be received. The
default value is 1492 and is used in the beginning of the PPP negotiation. In the normal negotiation, the peer will accept this MRU and will
not send a packet with an information field larger than this value.
MTU: Maximum Transmission Unit indicates that the network stack of
any packet that is larger than this value will be fragmented before the
transmission. During the PPP negotiation, the peer of the PPP connection will indicate its MRU and will be accepted. The actual MTU of
the PPP connection will be set to the smaller one of MTU and the
Peer's MRU. The default value is 1492.
MSS: Maximum Segment Size is the largest size of data that TCP will
send in a single IP packet. When a connection is established between a
LAN client and a host in the WAN side, the LAN client and the WAN host
will indicate their MSS during the TCP connection handshake. The defa ult
27
value is 1432.
Automatic Reconnect: When it is checked, it will maintain the PPP
connection all the time. If the ISP shuts down the PPP connection, it will
automatically reconnect the PPP session.
Authentication: When AUTO option is chosen, the PAP mode will run
first then CHAP.
PPP Configuration Status will be displayed at the bottom of this page
to show all the session names with its adapter (PVC number), mode
(PPPoA or PPPoE), service name, Account to Use (PPP Account ID),
Disconnect Timeout configuration, MRU, MTU, MSS, Authentication
Mode (Auto, CHAP or PAP), and Auto Reconnect configuration.
