The ISDN (Integrated Service Digital Network) SOHO (Small Office Home Office) router is a
network product used to connect LAN to the Internet or to the head office through the high-speed
ISDN interface.
The advanced all-in-one design can ease a your installation for connecting a your Ethernet card
directly to the built-in hub port. Apart from the flexible router capability, it also provides full ISDN
TA functions for both data and voice communication. This design supports two analog ports for the
normal telephony application, allowing you to connect the regular telephone, fax machine, and
answering machine to the analog port to make an outgoing call or receive an incoming call. One
data port allows you to configure the router and connects outside ISDN device with data protocol
like V.110, V.120. The SOHO router also features an optional soft-fax function to simulate the
G3/G4 fax operation with PC to save the fax investment.
The router provides a Windows based easy configuration software to help out with the entire
relative configuration. You can easily click the mouse to select the settings. The router also comes
with an easy-setup mechanism from telephone keypad, enabling some of the configuration being
made through the regular telephone while checking the setting on the LCD panel.
The router supports BACP (Bandwidth Allocation Control Protocol)/ BOD (Bandwidth On
Demand) function which allows you to utilize the 128k ISDN bandwidth with a demanded manner.
When using the ML-PPP (Multi-Link PPP) connection, the entire 128k ISDN bandwidth is used
for accessing the Internet. With the aid of BOD, the router automatically releases one B channel as
soon as the phone receiver is picked up to make a call. It also tells router to returns to two B
channels for 128k ML-PPP connection when the phone receiver hung up. Upon an incoming call,
the router releases one B channel automatically and return to 128k ML-PPP connection as soon as
one gets off the phone.
The RIP (Routing Information Protocol) and DHCP (Dynamic Host Configuration Protocol) save
the network administrator a lot of effort on maintaining the entire relative network configuration.
E-mail sharing capability allows a connected LAN user to have the e-mail address distinguished,
while using the same e-mail address in ISP. The router will automatically distinguish the
transmitting/receiving mail to the designated person.
The router complies with ITU-T Q.921, and Q.931 for D channel protocol as well as provides
switching type selections for different countries. The router is equipped with flash EPROM for
future software upgrade through the data port.

1.1 Features
•Integrated all-in-one design for ISDN TA, NT1, hub, and router
It saves the expense on purchasing NT1 and hub device. Moreover, it eases the cable
connection and separates installation for the all-in-one design.
•One page quick configuration guidance
With the one-page quick configuration guidance, the end-user can install the router following
the step-by-step procedure and operate the router easily. Even the first-time user will have no
problem following the instruction to link to ISP (Internet Service Provider) and connect the
LAN correctly.
•On line remote maintenance
The router has a built-in a remote maintenance facility to help the end-user to troubleshoot.
The maintenance center can dial in remotely to diagnose and correct the wrong settings to fasten
connection to the ISDN network.
•Two analog ports supported for normal telephony application
It allows you to use regular telephone to make outgoing/incoming calls just like using a regular
telephone at home.
•Support BACP/BOD for dynamic bandwidth demand
With the voice priority first mechanism at work, it fully utilizes the 128K ISDN bandwidth to
ensure no voice calls missing. Under ML-PPP connection, the router can automatically release
one B channel for voice communication and return to 128K bandwidth when the receiver hung
up.
•Dial On Demand to save communication cost
Dial-On-Demand activates the PPP link when needed. Whenever there is an outgoing packet,
the router makes an outgoing connection automatically and disconnects the PPP link after the
system is idle for specific amount of time (configured by the user) to save cost on
communication.
•Dial-in and call back security
The dial-in function enables you to remotely access your LAN. The call-back security can
protect your LAN from any attempts of illegal accessing.
ISDN Router Manual V.1.1

•Two standard RJ45 modular jack for S/T interface
The built-in two standard RJ45 S/T ports are for constructing a multi-drop connection to share
the same ISDN line.
•LCD display panel and LED indication
They provide visual display for you to monitor every status and message during the whole
connection process. You can see the calling party number (Caller-ID) immediately on the LCD
whenever the router receiving an incoming voice or data call. You can also check all of the
settings on the LCD panel.
•Battery backup utility
It automatically switches over to battery mode when local power source is off. In the battery
backup mode, you can still make outgoing calls or receive incoming calls.
•DHCP (Dynamic Host Configuration Protocol) function supported
DHCP allows the router to assign the IP address dynamically for the connected host on the LAN
that supports DHCP client. This saves the network administrator’s effort in maintaining the IP
address on the LAN and makes the IP address reusable.
•NAT (Network Address Translation) function supported
The NAT function converts all inside IP addresses to one single outside IP address. By doing so
you can translate all of the connected workstations’ IP addresses to single one and pay only one
IP account cost to the ISP.
•E-mail sharing
The e-mail sharing capability allows you to pay and use only one e-mail address account for all
of the users connected to the router. The router automatically receives and allocates mails to
designated mail users.
•RIP (Routing Information Protocol) function supported
With RIP the router can exchange renewed routing information with other routers automatically.
This help saves expense and manual labor on maintaining the routing table.
•Firewall security built-in
The built-in firewall can stop unauthorized communication between an organization’s intranet
and the outside, preventing the system being hacked from the outside.

other ISDN devices through these useful data protocols. You can use any terminal program like
HyperTerminal and make a data connection with other ISDN TA using the above protocol.
•Soft-Fax function
The router can bundle with the RVSCOM package (an end-user needs to order this RVSCOM
CD) running on PC to simulate a G3/G4 fax machine. With this function you can transmit
/receive G3/G4 fax in Word, Excel, Power Point format automatically. This not only saves the
budget on a fax machine but also eases the management of the fax files directly from PC.
•Local supplementary service
The router can simulate mini-PBX function for voice application such as inner intercom, call
waiting, call transfer, call forwarding, and three party conference all locally without doing it via
the internet.
•Easy setup from telephone keypad
The router also provides a quick setup mechanism through regular telephone. The end-user
may press some sequence code to enter the programming mode and setup some configuration
directly from the telephone keypad while checking the result displayed on the LCD panel.

4. Installing the Router
4.1 Entering AT command mode
To operate the router, you need to set up the necessary configuration. Follow these steps to setup
the router.
(1) Connect your PC with RS232 cable to router’s DTE port.
(2) Use any terminal programs that support ASCII file transfer function, such as HyperTerminal.
(3) Enter into the terminal mode and make sure that the terminal program had set the following
configuration.
l 115200 baud rate
l 8 data bit, no parity, 1 stop bit (8N1)
l Hardware flow control
(4) Type AT and check router responded with “OK”. If the router responded “OK”, meaning that
you have successfully entered into AT command mode. Otherwise please check the RS232
cable to see if it’s connected ok, or check if the COM port setting was correctly.
4.2 Setting ISDN telephone number
Similar with the regular PSTN (Public Switch Telephone Network) line, it has an unique
telephone number. When you apply the ISDN line from PTT or service provider, you will be
assigned an ISDN line number. But due to 2B+D technology, the ISDN allows you to have
two numbers in one ISDN line. The local PTT or service provider may assign two different
numbers to you. One is the line-number ( registered as the number of this ISDN line), the
other one is the DDI (Direct Dial In) number (allowing someone to call in directly using this
DDI number). Therefore you can apply two different numbers for both analog ports of TEL-A
and TEL-B. If you apply only one set of number (line number), the router will ring TEL-A and
ISDN Router Manual V.1.1
14
TEL-B alternatively upon an incoming call. You may setup to ring TEL-A only or TEL-B only
by AT$CG (global call select setting) and AT$CP (receive priority setting). Telephone
numbers of TEL-A and TEL-B can also be distinguished by sub-addressing.
To setup the telephone number for TEL-A and TEL-B, you issue the following AT command.
lSetup line number to TEL-A
AT!D1 = 3930219 (where 3930219 is the applied line number from PTT)
lSetup telephone number to TEL-B
AT!D2 = 3930217 (where 3930217 is the applied DDI number from PTT)
lSetup SPID to TEL-A
AT!S1 = 50839302190101 (where 50839302190101 is the SPID number from PTT)
lSetup SPID to TEL-B
AT!S2 = 50839302170101 (where 50839302170101 is the SPID number from PTT)
lSetup data port number
AT%N = 3930217 (assign the telephone number to data port)
Note: SPID is necessary only for the Northern American users that connect with AT&T 5ESS or Nortel
DMS100 switch type or NI1 switch type.
4.3 Setting ISDN switch
To make your router work and connect to the ISDN network, you need to setup correct switch type
with your local ISDN exchange. Different countries may have different ISDN switch types.
Therefore you should consult your local PTT to setup the right switch type.
Type AT!Wn to Setup switch type:
n = 0 AT&T 5ESS
n = 1 Nortel DMS-100
n = 4 European NET3
n = 5 Australia switch
n = 6 Japan INS64 switch
n = 7 NI-1
Make an incoming or outgoing call to test the setting.
Note: if the switching type is setup wrong, the router may not place incoming or outgoing calls.
ISDN Router Manual V.1.1

4.4 Quick Configuration
To minimize the configuration setting and connect into the ISDN network for voice and
Internet access. The router provides a one-page quick configuration procedure to ease all of
the necessary setting. Follow the this quick configuration to enable you to connect to the
Internet within a couple of minutes. Please see Chapter 5 for quick configuration guidance.
4.5 User Interface
One of the strong features of the SOHO router is that comes with the ISDN TA functionality. Hence
the router user interface also incorporates the AT command interface. This allows users who are
already familiar with TA command to continue using the TA functions of the router. We call this
interface the AT Command Interface.
The user interface that is used to operate the routing (not the TA) functionality of the SOHO router
is called the Command Line Interface (CLI). The CLI user interface is designed for the
sophisticated user to setup the router configuration more directly.
Basically, with just the AT Command Interface and the Router, the CLI user can drive SOHO to its
full capability. However, in order to make the router easy to configure and setup, we added a menu
driven interface so the user doesn't have to learn all the AT commands and the CLI commands to
operate the router.
This user interface contains:
* AT Command Interface
* Router Command Line Interface
When the unit first powered on, the AT Command Interface is activated. To display a list of
available commands to configure the ISDN interface, enter the following command:
ATI0
The following menu appears,
•ISDN interface can also be configured in Router CLI interface.

5. Router Command Line Interface
To access the Router Command Line Interface (CLI), enter the following command:
AT:
The SOHO router then presents a log on banner where you type in your ID and password to log on.
If logged on successful, the user is presented with the Router CLI Interface prompt that looks like
this.
at:
OK
Router Command Line Interface
Console Login: admin
Please note: The default Console Login is admin and Password is also admin.
As its name implied, the Command Line Interface is an interface where every command must be
entered in a single line.
A command is a sequence of tokens or words that are separated by spaces or tabs and terminated by
a carriage return. Each token represents as a sub-menu or level, and a choice of the next token is
available at every level. To exit CLI and return to AT command interface, type exit then the router
will return to the AT command mode.
Once at the command prompt, the user can get the available commands at that level by entering ? or
help for all the command with a description of each command that looks like this:
ISDN Router Manual V.1.1
18
CLI> ?
? config connect date exit flash help hwinfo
log menu ping reset show trace version
CLI> help
? -- Display menu options
config -- Change the configuration
connect -- Start a PPP connection
date -- Set the date
exit -- Exit the current session
flash -- Operations on the flash-based file system
help -- Display this help
hwinfo -- Display hardware information
log -- Operations on the log
Entering Command
There are two ways to enter commands to configure the router.
1. Enter multiple commands at the top level and terminate with a carriage return.
2. Enter a single command (one token) at the top level followed by a carriage return and goes
down one level of menu at a time until the desired command is completed. At each level, the
user can type help or ? to get a complete list of command for that particular level.
Example:
To configure the ethernet interface with the IP address 192.168.70.1 and with the subnet mask of
255.255.255.0
Method 1:
CLI> config interface ether ip address 192.168.70.1 255.255.255.0
CLI>
ISDN Router Manual V.1.1

Method 2:
Note: The user can type the remaining of the command at anytime in Method 2 in order to
complete the entire command sequence.
Tips: Some of the commands don’t need to be type all out. The number of
character(s) required for that command depends on if there is a similar
command (spelling) to it.
CLI> config

5.1 Quick Configuration to Internet
Before you can connect your LAN to the Internet you must obtain an ISDN internet account
from your local Internet Service Provider (ISP). Your local ISP should provide you the
following information when you register with them:
1. Account user ID and password
2. Dial in telephone number, you may need to have two phone numbers if you wish to
run Multilink Point-to-Point Protocol (ie. MLPPP).
When the above information is ready, you can configure the router with it to connect your LAN
to the internet. Configuring the router is very easy with the quick config "qconfig" command.
The router will prompt you to enter the ethernet IP address for the router, the ISP user ID,
password, and the ISP phone number. When you’re done typing the information, the router will
return you to the CLI prompt. At this point we recommend you to save all your configuration
by entering the command:
> config save
Now you are ready to launch the connection to the internet. To do this please use the connect
command:
> connect <user id>
The router shall attempt to connect you with your local ISP. If succeed you should see a
message indicating that connection with the internet is successful. At this point, depending on
weather your LAN has private IP addresses or not, you may want to configure NAT (Network
Address Translation) to translate all of your private IP addresses to the public IP address. This
can be done with the this command:
> config ip nat add isdn
Simple as that! Now you can start surfing.
Quick configuration is designed to help users with limited network knowledge to setup the SOHO
router and connect to the internet with ease within the least amount of time.
To start quick configuration for the internet, enter qconfig at the command prompt. An example of
the quick configuration screen is displayed as shown below.
ISDN Router Manual V.1.1

5.3 Configure Ethernet Interface
config interface ether ip address <IP address> <netmask>
Configure the ethernet interface with the <IP address> and the <netmask>
Every machine connected to the TCP/IP network must have an unique IP address. The IPaddress is always presented by dotted decimal format (four 8-bit number between 0 to 255
separated by periods), e.g. 123.97.35.7. The IP address was defined by the IANA (Internet
Assigned Numbers Authority). The IANA had reserved the following IP address for the private
network, therefore it is recommended that you follow the defined rules.
10.0.0.0- 10.255.255.255
172.16.0.0- 172.31.255.255
192.168.0.0- 192.168.255.255
An IP address consists of network ID and host ID. The netmask is used to extract the network ID from the
dotted decimal notation. The router will automatically calculate the network ID from the IP address and
netmask. This command configures the IP address and network mask for the LAN of this router.
ISDN Router Manual V.1.1

config interface ether physical show
Display the current physical address of the ethernet
The physical ethernet address is a 48-bit unique address preset during manufacturing. The
physical address is the lowest hardware ID for that ethernet device and was assigned by the
manufacturer. Use this command to check the physical ethernet address.
config interface ether show
Display the current settings of the ethernet interface
5.4 Configure ISDN Interface, Authentication and VJ compression
config interface isdn ip address <IP address> <netmask>
Configure the ISDN interface with the IP address <IP address> and the netmask <netmask>
Like the IP address and netmask configured for the LAN interface, sometimes you need to setup
the IP address and netmask for the WAN/ISDN (Wide Area Network) interface for LAN-toLAN application or static IP address requested by the ISP (Internet Service Provider) site. Under
normal situation you don’t need to setup the WAN IP address as most of the ISP will
assign the IP address to the router dynamically.
config interface isdn ppp authen <pap,chap,both>
Configure the authentication protocol when the PPP or ML-PPP connection is established.
When establishing the connection with the remote site under PPP or ML-PPP protocol, it is
necessary to specify the authentication mechanism by both parties. If pap (Password
Authentication Protocol) is selected the router will use PAP only, the PAP will send username and
password in plain text for authentication. If chap (Challenge Handshake Authentication
Protocol) is selected the router will use CHAP only, the CHAP will scrambles the password
And sent for authentication. If both is selected, the router will try PAP when remote site
requested PAP or it will try CHAP when remote site requested CHAP.
config interface isdn ppp ipcp vjcompression
Turn on the VJ (Van Jacobson) compression function for IP header.
The VJ compression is a mechanism to compress the IP header of a packet during transmission
ISDN Router Manual V.1.1
24
by reducing the size of IP header for speeding up transmission performance. The remote site
must also support the VJ compression, otherwise the router won’t compress the IP header if the
remote site did not support the VJ compression.
It is suggested to turn on VJ compression.
config interface isdn ppp ipcp none
Turn off the VJ compression function.
5.4.1 Configure Dial-In and Call Back Function
config interface isdn ip pool <initial_ip_addr>
Configure the IP address assignment of the PPP connection.
This command is used for the remote dial-in function. The router can accept the remote user to
dial in with PPP connection and assign the IP address for the remote site if the remote site did not
setup its own IP address. By the remote dial-in function the remote user can access the LAN
resource just like it is connected the router locally. The router will check both the username and
password for valid access.
Configure the user account for PPP or ML-PPP connection.
The router allows you to store multiple user accounts for both dialing in and out purpose. For
example, you can store different usernames and passwords for corresponding ISP when dialing
out. Also if the router received an incoming call for remote dial in, it will check the valid
username and password based on the stored User Account Table. The router will compare if the
dial-in username and password was defined in the User Account Table. If it is a valid account,
the router will accept the call and connect, after that the remote site can access the LAN resource
through the router. If the user account is invalid, the router will disconnect immediately.
The maxchan specifies to use 1-B channel for PPP connection or 2-B channel for ML-PPP
connection. For 1-B channel (64k, PPP) connection you need to setup phone#1, the router will
make an outgoing connection based on phone#1. For 2-B channel (128K, ML-PPP) connection
ISDN Router Manual V.1.1
25
you need to setup phone#1 and phone#2, the router will make an outgoing connection by dialing
phone#1 and phone#2. If under ML-PPP connection but just setup phone#1 then the router will
make an outgoing connection by dialing the phone#1 twice.
If callback is set to ‘yes’, then after the router checks valid dial-in username and password, it
disconnects immediately. It also calls back to the remote site based on the remote site’s
telephone number. The router supports MS-CBCP (MicroSoft Call Back Control Protocol)
therefore when the remote user enables MS-CBCP function for call back, the router will
automatically disconnect and call back the remote site.
config interface isdn ppp set user <username> password <password> maxchan {1,2}
callback {yes,no} phone <phone#1> <phone#2>
Modify the current password and relative settings for the specified username in the User
Account Table.
config interface isdn ppp delete user <username>
Delete the current user account entry.
This command will delete all of the setting in the User Account Table for the specifiedusername. After this command the deleted username become no longer available to the router.
5.4.2 Configure DOD (Dial On Demand)
config interface isdn ppp dod {on, off} user <username> <idle_timer>
Set dial-on-demand to remote user.
If dod is ‘on’ for the specified username, whenever there is an outgoing packet, the router
will search the first username which enabled dod ‘on’ in the User Account Table, and make an
outgoing connection automatically. If there are several usernames enabled dod ‘on’ in the UserAccount Table, the router will always search sequentially the first one which labeled dod ‘on’
and make an outgoing call based on that telephone number.
The idle_timer (unit: second) defines the idle time for disconnection. If there’s no packet
transmission occurred within the defined idle time, the router will disconnect the link
automatically to save the communication cost and to prevent any mistake for disconnecting.
ISDN Router Manual V.1.1
26
5.4.3 Configure BOD (Bandwidth On Demand)
config interface isdn ppp bod incre <increase> decre <decrease>
Set bandwidth-on-demand to router. By default BOD is enabled on the router.
Bandwidth on Demand (BOD) is a feature that allows the second telephone line connection
to the internet to be made only if there is enough traffic between the router and the internet which exceeds the capacity of the first telephone line connection. Since it is likely that there
are many periods of little activity where there may be no data to be sent between the router
and the internet, this feature helps the user to save a considerable amount on connection with
the ISDN phone line.
To enable BOD (throughput BOD) enter the following command at the CLI prompt:
> config int isdn ppp bod incre 80 decre 20
This tells the router that it should bring up the second telephone line connection when the
traffic level on the first telephone line exceeds 80% of its capacity. At the same time if the
traffic level on the first telephone line connection drops below 20% of its capacity, the
second telephone line connection should be terminated.
To disable BOD, i.e., if you don’t want the second telephone line connection to be brought
down even if there is no traffic on the line, enter the following command:
> config int isdn ppp bod decre 0
The other BOD function (resource BOD) acts as voice priority first manner. When the router
connected by 2B channels (ML-PPP), if you want to place an outgoing voice call, the router
will automatically drop 1B channel for your dialing to the destination. As soon as you hang up,
the router will automatically connect the second B channel again to return ML-PPP connection.
The same mechanism works also under ML-PPP connection: If someone made a voice call to
the router, it will drop 1B channel to accept the call and ring TEL-A or TEL-B. As soon as the user
hang up, the router will again connect the second B channel and back to ML-PPP.
ISDN Router Manual V.1.1
27
5.4.4 Configure ISDN Switch Type and Directory Number
config interface isdn switch type {etsi,ntt,ni1}
Configure the switch type for an ISDN interface
Check with your local PTT to setup proper ISDN switch type otherwise the router may not
operate correctly.
etsi : European DSS1 switch (also called NET3)
ntt: Japan INS64 switch (also called NTT-KDD)
ni1 : Northern American National ISDN-1 switch
You should check the supported switch type by your router by typing ATI2 in AT command
mode.
Note: you can also use AT!W to setup the appropriate switch type in AT command mode.
Configure the service provider id and directory number for an ISDN interface
Setup the telephone number and Service Profile Identifier (SPID) to TEL-A and TEL-B. The
spid#1 and dn#1 will be assigned to TEL-A. The spid#2 and dn#2 will be assigned to TEL-B.
The SPID is always obtained from your local PTT for service and identification purpose.

The ping is a useful internet program to check the if the specified IP address host device is alive
or not. If the destination host is alive then the router should receive the echo from the host and
display the message. Otherwise if the destination host did not reply after time out, the router will
display timeout message.
qconfig
Quick configuration of the router to connect the internet.
The qconfig is a very useful command to setup the minimum requirement of the router. After the
quick configuration procedure you should be able to connect into the internet and place voice
call. The qconfig will request you to enter IP address, IP mask, switch type, directory number,
and remote destination number. Please see Chapter 5 for detail operation.

5.6 Configure IP Routing Table
There are two ways to construct the routing table. One is by manually setup one-by-one, so called
static route. The other is setup automatically by the router, so called dynamic route.
addAdd an entry to the firewall/accounting rule list
deleteDelete an entry from the firewall/accounting rule list
flushThis causes all entries in the firewall chain to be removed except the fixed default
policy enforced by the kernel (index 65535). Use caution when flushing rules, the
default deny policy will leave your system cut off from the network until allow
entries are added to the chain.
zero <index>When used without an index argument, all packet counters are cleared. If an index is
supplied, the clearing operation only affects a specific chain entry.
rejectDrop the packet, and send an ICMP host or port unreachable (as appropriate) packet
to the source.
allowPass the packet on as normal. (aliases: pass and accept)
denyDrop the packet. The source is not notified via an ICMP message (thus it appears
that the packet never arrived at the destination).
countUpdate packet counters but do not allow/deny the packet based on this rule.The
search continues with the next chain entry.
allMatches any IP packet
icmpMatches ICMP packets
tcpMatches TCP packets
ISDN Router Manual V.1.1
32
udpMatches UDP packets
The address specifies from <address/mask>[port] to <address/mask>[port] [via <interface>]
You can only specify port in conjunction with protocols which support ports
(UDP and TCP).
The via is optional and may specify the IP address or domain name of a local IP interface, or an
interface name (ie, isdn or ethernet ) to match only packets coming through this interface.
Example commands for firewall
This command will deny all packets from the host 129.97.34.1 to the telnet port of the host
192.168.34.1 by being forwarded by the router:
>config firewall add deny tcp from 129.97.34.1 to 192.168.34.123
The next example denies any TCP traffic from the entire 129.98.3.0 network (a class C) to the
192.168.34.1 machine (any port).
>config firewall add deny tcp from 129.98.3.0/24 to 129.99.1.2
Firewall is an internet traffic filtering process which is used to keep certain type of traffic from
entering or leaving a specific site. This control mechanism is used mainly for security purpose
where an organization can selectively reject traffic on the internet.
There are currently two distinct types of firewalls in common use on the Internet today. The first
type is more properly called a packet filtering router, where the kernel on a multi-homed machine
chooses whether to forward or block packets based on a set of rules. The second type, known as
proxy servers, rely on daemons to provide authentication and to forward packets, possibly on a
multi-homed machine which has kernel packet forwarding disabled.
The router uses the first type of the packet filtering process to implement the firewall. A fairly
sophisticated level of packet filtering process has been implemented on the router; therefore, it is
expected that a novice user may take sometime to get familiar with all of the firewall commands
and features.
The firewall can filter the following type of traffics:
ISDN Router Manual V.1.1
33
•IP, ICMP, TCP, UDP
•It can reject the above traffic from a certain machine given its IP address
•It can reject the above traffic on a certain port. This is useful because one can configure
firewall to selectively reject Telnet, Ftp, IRC, News, Web surfing, etc.
Let us try to answer this question by picking up an example, hopefully this example can help you to
understand the steps required in configuring a firewall better.
Let‘s say you want to configure firewall to disallow someone on the internet to telnet into the
company computers on the LAN. Since we know that telnet always use TCP port #23, we will
configure the router to deny any TCP traffic on this port. The commands are as follow:
Enter the rule for denying TCP traffic on port #23
> config firewall add deny tcp from any to any:23 via isdn
By default, firewall will be off. When it is turned on, all traffic will be denied. After that you can
add in your own rules to selectively let some or all of the traffic to go through the router.
The firewall also allows you to add new rule in between existing rules. For example if there are
two existing rules with index number 100 and 200, then we can add a new rule in between those
two rules:
>config fire add 150 allow ip from any to any
then this rule will be placed between 100 and 200.
config ip nat add isdn
The NAT configuration has been separated from the firewall configuration. That is if the
firewall is not turned on, then in order to have NAT you must enter the command.
The router has the capability to perform IP routing with the addition of changing the IP
address in the packets on the fly, i.e. as the data is passed through from the LAN to the
Internet. In router this feature is called Network Address Translation (NAT). It allows
multiple machines connected to a LAN access the Internet through only 1 IP address. For
this reason routers with NAT are also called IP Share devices.
Configuring NAT on the router is easy. When the connection has been established with the
Internet, enter the following command:
ISDN Router Manual V.1.1
34
When the firewall is turned on, in order to have NAT you must enter the command :
>config fire add divert ip from any to any via isdn
5.8 Connecting/Disconnecting ISDN
connect <username>
Start a PPP or ML-PPP connection with the username.
This is a manual method to make connection. The router will automatically extract the telephone
number associated with the username and make an outgoing call to connect with the destination
site. The PPP/ML-PPP connection will be decided by the maxchan set of the username stored in
the User Account Table. You can connect two username at the same time under PPP
connection for each user. Therefore the router can connect two different destinations
simultaneously.
disconnect <username>
Stop a PPP or ML-PPP connection of the current user.
When disconnect one destination link, you need to specify the corresponding username.
Because the router may connect two separated link with two username, each under PPP
connection. Therefore you must specify which one to be disconnected.
5.9 Save and Delete Configuration
config save
Save the configuration from memory to flash. All the changes up to this point are saved onto
EPROM and will take effect at the next reboot.
delete all
Delete all of the current configuration. Only take effect after resetting the power of the router.

5.12 Router Test Setup Procedure
There are three steps to the router test setup:
Connect the router to your ethernet network
Connect the router to the ISDN interface (ARCA box and Total Control Hub)
Configure the router
The following figure is used as an example to illustrate how to connect the router to various
network components and configure the router:

The labeled addresses will be used to configure the IP addresses for all the corresponding devices.
Connect all the network components as shown in the figure.
After loading up the AT command interface on your PC, which has the IP address 129.97.35.58, the
router can be configured as follows:
Type AT: to go to router command interface mode.
Configure the ethernet ip address for the router:
CLI> config int ether ip add 129.97.35.1 255.255.255.0
ISDN Router Manual V.1.1
39
Configure the user name and password for authentication:
CLI> config int isdn ppp add user john pass master phone 3840001
Alternatively, the router can be configured to use both data channels to increase the bandwidth:
CLI> config int isdn ppp add user john pass master maxchan 2 phone 3840001 3840101
To insure the router is working properly the router can be tested as follows:
On your PC, test the router’s ethernet interface:
ISDN Router Manual V.1.1
43
ping 129.97.35.1
The router shoud respond. If it does not respond then there should be a problem.
The following tests are done similarly:
Test the router’s ISDN interface:
ping 192.168.1.2
Test the connectivity with the Total Control hub:
ping 192.168.1.1
Test the connectivity with the NT server:
ping 192.97.34.1
ISDN Router Manual V.1.1

5.14 Setup LAN-to-LAN Connection
To setup a LAN-to-LAN connection you need to have the following information before you can
do it.
•Remote router ISDN telephone numbers
•Remote router logon user ID and password
•Remote router ISDN IP pool and ISDN IP address must be configured before dialing in can
take place. You can usually decide on an arbitrary IP address and IP pool for the purpose of
doing LAN-to-LAN connection. For example using 192.168.1.1 for IP address and
192.168.1.2- for IP pool would be an acceptable choice.
With the above information can begin to configure your remote and local router for LAN-toLAN connection.
Configure Remote Router for LAN-to-LAN Connection
If the remote router is also the same model of router then follow the following steps:
1. Setting up you account for dialing in
> config int isdn ppp add user <user id> pass <password>
2. Configure IP address
> config int isdn ip address 192.168.1.1 255.255.255.0
3. Configure IP pool
> config int isdn ip pool 192.168.1.2
That's it, you are done with configuring the remote router. In the case that the remote router
is not the same model then you should consult the router's documentation in order to do
similar configuration for LAN-to-LAN connection.
Configure Local Router for LAN-to-LAN connection:
Assuming that the local router is the current router, the following steps are used to configure
the router:
ISDN Router Manual V.1.1
45
1Setting up dialing out user account, including telephone numbers for dialing out
> config int isdn ppp add <user id> pass <password> max 2 phone <dial out phone
#1> <dial out phone #2>
2Issue the connection command
> connect <user id>
Your local router should make the connection to the remote router, after that you should be
able to establish any TCP/IP connection from one LAN to another.

6. AT COMMAND
6.1 Description of AT Command
Hayes command set is a standard for Hayes modem commands for its Smartmodem 300. Most
modem manufacturers have adopted this command set in order to have Hayes compatible. The
command set used by the Smartmodem 300, as well as most modems today (with a few additional
new advanced commands), is known as the AT command set. AT stands for attention, and is placed
in front of actual content of command so that the router knows what follows is an command
directed at the modem or router. With the exception of some “A/” and “+++” command, “AT”
command is the process to place command to the router.
Different modems or routers may have slightly different command sets, but generally speaking,
most of the routers follow the standard set by Hayes.
6.1.1 AT Command
When you connect terminal equipment (like PC) with the router, after typing AT command ending
with [ENTER] key, TA will process the command and then return the result code to the terminal
equipment. Each AT command must starts with “AT” and end with [ENTER] key (with the
exception of “A/” and “+++” commands).
Command Format
The following is the format of AT command:
AT
CommandvaluecommandvalueCRLF
Result code has two styles (Verbose and Numeric). The following are their formats:
CRLFResult code(Verbose)CRLF
Result code(Numeric)CR
S register
The S register is used to store the settings including
auto answer mode
escape sequence character
V.110 connect speed .....etc.
