2. Management via Console Port

Step 1. Connect the Console Port to the Serial Port

For the first configuration of this router, you need to use terminal emulator software on a workstation and connect it to the router through the console port. Connect the 9-pin end of the console cable (9-pin to 9 -pin console cable supplied) to the console port of the router and the 9-pin end to a serial port (COM1, COM2 or other COM port) of your workstation.

Step 2. Configure the Serial Port

For the best access to the router, use your terminal emulation program (such as HyperTerminal in Windows) to set your COM protocol to the following settings:

Baud rate: 115200 bps Data bits: 8 Parity: None Stop bits: 1 Flow control: None

Step 3. Connect All Cables to the Network

The procedure for connecting cables differs depending on whether or not your telephone equipment is connected to a POTS splitter.

15

POTS Splitter Configuration (ADSL over POTS)

A POTS splitter separates data signals from voice signals on your telephone line. The POTS splitter works by running a separate data line from the voice line, so that the ADSL router has a dedicated cable for data transmission. Hereunder shows the connection of all cables to the Router.

Note: The POTS splitter may also be installed on the outside of the house adjacent to the telephone network interface device (NID).

3.3 Connecting the ADSL Router to your network

Unlike a simple hub or switch, the setup of the ADSL Router consists of more than simply plugging everything together. Because the Router acts as a DHCP server, you will have to set some values within the Router, and also configure your networked PCs to accept the IP Addresses the Router chooses to assign them. Generally there are several different operating modes for your applications. And you can know which mode is necessary for your system from ISP. These modes are router, bridge, PPPoE+NAT and NAT and PPPoA+NAT. Actually all these are for IP address of WAN.

1. If your ISP provides RFC1483 Routed mode, it means the IP address of LAN will be routed via WAN. You should set the "Router" mode in the ADSL router for this situation, also set the IP address / netmask of LAN and VPI/VCI of WAN. Then save and reboot Router, it will work fine with your whole system. The computer should be set the fixed assigned IP address with the same domain at this mode.

2. If your ISP provides RFC1483 Bridge mode plus PPPoE, it means the IP address of computer or router will be assigned automatically via PPPoE. There are two methods you can use at this mode. First you can set the "bridge" mode, give VPI/VCI of WAN and install PPPoE driver on your computer. Then save and reboot router, it will work fine with your whole system. You need to use Dial_Up_Network to get the IP address of computer every time. Second method you can set the "PPPoE+NAT" mode, give VPI/VCI of WAN and set user's name & password for PPPoE on your router. Then save and reboot router, it will work fine with your whole system. The computers should be set as DHCP client to get IP dynamically.

3. If your ISP provides RFC2364 mode, it means the IP address of router will be assigned automatically via PPPoA. You can set the "PPPoA+NAT" mode, give VPI/VCI of WAN and set user's name & password for PPPoA on your router. Then save

19

and reboot router, it will work fine with your whole system. The computers should be set as DHCP client to get IP dynamically.

4. If your ISP provides RFC1483 Routed and the serial static IP address for you, there are two methods you can use at this mode. First you can set the "router" mode and give VPI/VCI of WAN. Then save and reboot router, it will work fine with your whole system. The computers should be set the fixed assigned IP address at this method. Second method you can set the "NAT" mode, give VPI/VCI/ IP address /netmask of WAN. Then save and reboot router, it will work fine with your whole system. The computers should be set as DHCP client to get IP dynamically.

3.4 The relative configuration on your computers

Please follow the steps to install your system via web server at first time:

1. Power everything down, including your PCs, and ADSL Router.

2. Connect a crossover network cable from one of your PCs' Ethernet ports to the LAN port on the back of the Router or connect a straight network cable from hub (or switch) to the LAN port on the back of the Router.

3. Connect the power-adaptor to the Power port on the rear of the Router, then connect to a power outlet using the power cord included in the Router's packaging.

4. Power on one of your PCs and login if you are asked to. When you reach the desktop, click the Start button, select Settings, and then select Control Panel.

5. Double-click the Network icon.

6. In the Configuration window, highlight the TCP/IP that has been associated with your network card or adapter. (Do NOT configure TCP/IP->Dial-up Adapter.) Click Properties. If the TCP/IP Protocol isn't listed in the Configuration window, try to install it.

32

6. Forwarding

The feature allows Internet users to communicating directly with a computer that resides inside a firewall using Network Address Translation (NAT) to hide the identity of internal machines from the outside world.

Virtual Server has the highest priority, port forwarding is secondary. Port triggering is used to deal with application protocols that create separate sessions so it is less priority.

If there are some applications on your network the highest priority application will get the port(s) for communication and the others will be disconnected and reconnected until the highest one releasing the port(s).

33

7. Multiple NAT and Multiple DMZ

Multiple NAT

NAT (Network Address Translation), it allows an organization to present itself to the Internet with one address. NAT converts the address of each LAN node into one IP address for the Internet and vice versa. It also serves as a native firewall by keeping individual IP address hidden from the outside world.

This deivce provides grouping local IP range access Internet via more than one WAN IP.

Multiple DMZ

DMZ (DeMilitarized Zone) is a middle ground between an organization's trusted, internal network and an untrusted, external network such as the Internet. The DMZ is a subnetwork (subnet) that may sit between firewalls or off one leg of a firewall.

You can set more than one DMZ host in this DMZ parameter to expose host/server to the Internet.

When the DMZ host is mapped to a WAN IP, please enable the local host as DMZ host in the DMZ page simultaneously.

Page 18: FCC Part 68 - :: TECNICAL SUPPORT :)support.loxinfo.co.th/adsl/pdf/micronet3352.pdf ·  1 CE Declaration of conformity This equipment complies with the requirements relating to

34

8. DMZ

DMZ setting exposes an internal host to the Internet. Check the box and key in the host IP to enable this feature.

9. DDNS

DDNS (Dynamic DNS) service points a fixed hostname to a dynamic WAN IP address or static IP address, allowing your computer to be accessed from various locations on the Internet without knowing your current IP. With a DDNS connection you can host your own web site, email server, FTP site and more at your own location.

35

10. Save & restart

To update the configuration, the server must be restarted. When you click on the Save button, the router will restart and your browser session will be disconnected.It may appear that your browser session doesn' t work. When the ADSL Router restarts after a few seconds, you can click on the Reload button, or close your browser and then re-open it.

4.3 Advanced Configuration

1. Static Route

Static Route forwards data packets from local area network to another based on routing tables and routing protocols.

This page let you key in the remote network information.

2. RIP

RIP (Routing Information Protocol) is part of the TCP/IP protocol suite. It indicates that the path used to pass traffic between routers is based on the fewest number of hops between the source and destination IP addresses included within the packet. It should be concerned that RIP wastes bandwidth and reduces the router’s performance.

Chapter 6 Troubleshooting

This chapter gives information about troubleshooting your ADSL Router. After each problem description, instructions are provided to help you diagnose and solve the problem.

Basic Function

• After you turn on power to the Router, the following sequence of events should occur: The Router performs a self-test and loading program for 40 seconds, during which the Diag LED should blink and then turn off. The OP LED starts to flash at the 1 second interval. The OP LED must always flash.

• The Local Ethernet connections are correctly made to operational devices, and LAN LED should be on. And Link/Act LED will flash with data transferring.

• The WAN port is connected successfully with the ADSL line from Telecom, the LNK LED should be on. And the LNK LED will flash with data transferring. If any of these conditions does not occur, refer to the appropriate following section.

Diag LED Not Flash at the beginning of power on

• Make sure that the power cord is properly connected to your Router and that the power supply adapter is properly connected to a functioning power outlet.

• Check that you are using the 9Vdc (1.5A) power adapter for this

product. If the error persists, you have a hardware problem and should contact technical support.

59

LAN LED Not On

If the LAN LED does not light when the Ethernet connection is made, check the following items:

• Make sure you are using the correct cable.

• Make sure that the Ethernet cable connections are secure at the Router and at the hub or workstation.

• Make sure that power is turned on to the connected hub or workstation.

- If you are connecting one of LAN port of ADSL Router directly to the uplink (MDI) port of a hub, use the straight-through network cable.

- If you are connecting one of LAN port of ADSL Router to a normal (MDI-X) hub port, use the crossover network cable.

Troubleshooting the ISP Connection

• If your Router is unable to access the Internet, you should first determine whether the Router is able to obtain a WAN IP address from the ISP.

• Unless you have been assigned the static IP address, your Router must request an IP address from the ISP.

• You can determine whether the request was successful using either the Browser interface or the C onsole interface.

To check the WAN IP address from the Console interface: • Go to Console interface - Monitor- WAN- Active

• Check that an IP address is shown for the WAN Port If it is "NO" on active table, your Router has not obtained an IP address from your ISP.

Page 31: FCC Part 68 - :: TECNICAL SUPPORT :)support.loxinfo.co.th/adsl/pdf/micronet3352.pdf ·  1 CE Declaration of conformity This equipment complies with the requirements relating to

60

If your Router is unable to obtain an ISP address from the ISP, the problem may be one of the following:

• Your Router may be set incorrectly the login name and password for PPPoE or PPPoA mode. Or your Router may be set wrong WAN IP address fo r routing mode. If you use bridge mode, you should take care the setting of your workstation.

• Your ISP may check for your PC's Host Name. Assign the PC Host Name of your ISP account to the Router as System Name, or as Host Name in the browser-based Setup Wizard.

• Your ISP only allows one MAC address to connect to Internet, and may check for your PC's MAC address. Inform your ISP that you have bought a new network device, and ask them to use the Router's MAC address.

If your Router can obtain an IP address, but your PC is unable to load any web pages from the Internet:

• Your PC may not recognize any DNS server addresses. A DNS server is a host on the Internet that translates Internet names (such as www addresses) to numeric IP addresses. Typically your ISP will provide the addresses of one or two DNS servers for your use. If you entered a DNS address during the Router's configuration at NAT mode, reboot your PC and verify the DNS address. Alternatively, you may configure your PC manually with DNS addresses, as explained in your operating system documentation.

• Your PC may not have the Router configured as its TCP/IP gateway. If your PC obtains its information from the Router by DHCP, reboot the PC and verify the gateway address.

61

Troubleshooting a TCP/IP Network Using a Ping Utility

• Most TCP/IP terminal devices and Routers contain a ping utility that sends an echo request packet to the designated device. The device then responds with an echo reply. Troubleshooting a TCP/IP network is made very easy by using the Ping utility in the built-in Console interface at NAT mode or in your PC or workstation.

Testing the LAN Path to Your Router

You can ping the Router from your PC to verify that the LAN path to your Router is set up correctly.

To ping the Router from a PC running Windows operating system:

• From the Windows toolbar, click on the Start button and select Run.

• In the field provided, type Ping followed by the IP address of the Router at the NAT mode, as in this example: ping 192.168.8.1

• Click on OK.

You should see a message like this one: Pinging with 32 bytes of data If the path is working, you see this message: Reply from < IP address >: bytes=32 time=NN ms TTL=xxx If the path is not working, you see this message: Request timed out

If the path is not functioning correctly, you could have one of the following problems:

• Wrong physical connections -Make sure the Local LAN LED is on. -Check that the corresponding Link LEDs are on for your network interface card and for the hub ports (if any) that are connected to your workstation and Router.

Page 32: FCC Part 68 - :: TECNICAL SUPPORT :)support.loxinfo.co.th/adsl/pdf/micronet3352.pdf ·  1 CE Declaration of conformity This equipment complies with the requirements relating to

62

• Wrong network configuration - Verify that the Ethernet card driver software and TCP/IP software are both installed and configured on your PC or workstation. -Verify that the IP address for your Router and your workstation are correct and that the addresses are on the same subnet.

Testing the Path from Your PC to a Remote Device After verifying that the LAN path works correctly, test the path from your PC to a remote device:

• From the Windows run menu, type PING -n 10 followed by the IP address of a remote device such as your ISP's DNS server. If the path is functioning correctly, replies as in the previous section are displayed.

If you do not receive replies:

• Check that your PC has the IP address of your Router listed as the default gateway. If the IP configuration of your PC is assigned by DHCP, this information will not be visible in the control panel network utility. Go to the Run... window and run winipcfg in Win98 (or ipconfig in Win2000). The IP address of t he Router should appear as the Default Gateway.

• Check to see that the network address of your PC (the portion of the IP address specified by the netmask) is different from the network address of the remote device.

• Check console to verify the WAN status. If the menu indicates the WAN status as down, check that your ADSL line is connected and functioning. Or check the VPI/VCI setting of the Router with right values.

• If your ISP assigned a host name to your PC, enter that host name as the Router name.

63

• Your ISP could be rejecting the Ethernet MAC addresses of all but one of your PCs. Most broadband ISPs restrict access by only allowing traffic from the MAC address of your ADSL Router, but some ISPs additionally restrict access to the MAC address of a single PC connected to that modem. If this is the case, you must configure to allow the Router to "borrow" the MAC address from the authorized PC.

Troubleshooting the Console Interface Refer to the following instructions if you cannot access the Console interface by the serial port or by using the Telnet Protocol.

If you cannot access the Manager interface by the serial port: Verify that the Router is connected to the serial port of your terminal or computer using the included cable.

Check the configuration parameters of your terminal or communications program. The connection should be configured as follows: • VT100 terminal emulation 115200 bits per second. • No parity, 8 data bits, 1 stop bit, no flow control.

If you cannot access the Console by using the Telnet Protocol: Verify the Ethernet connection between your PC and the Router.

Frequently Asked Questions

What should I do when I forgot the user's name and password of management?

For security reason you should assign a password to proted your router against hacker attacks. When you forgot the user's name and password, you can do the procedure of Backup configuration file . There is a default configuration file named adsl.cfg in the disk.

What is the maximum number of IP addresses that the ADSL Router will support?

The Router will support to 253 IP addresses with NAT mode.

Where is the ADSL Router installed on the network?

In a typical environment, the Router is installed between the ADSL line and the LAN.

Plug the ADSL Router into the ADSL line on the wall and Ethernet port on the Hub (switch or computer).

How do I get Napster to work with the Router?

How can I not receive corrupted FTP downloads?

If you are experiencing corrupted files when you download a file with your FTP client, try using another FTP program.

65

The user may have many private addresses behind this single address provided by the ISP. Does the ADSL Router support any operating system other than Windows 95/98/2000/Me, or Windows NT?

Yes, it provides technical support for setup, configuration or trouble shooting of any non-windows operating systems.

What is Network Address Translation and what is it used for?

Network Address Translation (NAT) translates multiple IP addresses on the private LAN to one public address that is sent out to the Internet. This adds a level of security since the address of a PC connected to the private LAN is never transmitted on the Internet. Furthermore, NAT allows the ADSL Router to be used with low cost Internet accounts which only one TCP/IP address is provided by the ISP.

Web page hangs, corrupt downloads, or nothing but junk characters is being displayed on the screen. What do I need to do?

Force your NIC to 10Mbps or half duplex mode, and turn off the "Auto-negotiate" feature of your NIC as a temporary measure. (Please look at the Network Control Panel, in your Ethernet Adapter's Advanced Properties tab.).

Is the Router cross-platform compatible?

Any platform that supports Ethernet and TCP/IP is compatible with the Router.

With which type of firewall is the ADSL router equipped?

The ADSL Router uses NAT and TCP/IP port inspections.

66

Will the Router allow me to use my own public IPs and Domain, or do I have to use the IPs provided by the Router?

The Router mode allows for customization of your public IPs and Domain.

How can I check whether I have static DHCP IP Addresses?

Consult your ISP to confirm the information.

Why does the router dial out for PPPoE or PPPoA mode very often?

Normally some of game, music or anti_virus program will send out packets that trigger the router to dial out, you can close these program. Or you can set the idle time to 0, then control to dial out manually.

Why is that i can ping to outside hosts, but not access Internet websites?

Check the DNS server settings on your PC. You should get the DNS servers settings from your ISP. If your PC is running a DHCP client, remove any DNS IP address setting. As the router will assign the DNS settings to the DHCP-client-enabled PC.

How to use the DDNS?

DDNS means Dynamic DNS. You can vi sit http://www.dyndns.org to apply a Host name for your own web site. For example: www.smart.com. Save the Host name, user name and pass word in DDNS record. It doesn't matter your ADSL line with a fixed or dynamic IP. Users always access your web site by www.smart.com.

How to configure SP3352 working with VoIP device?

You can find the ports for VoIP in the list and open the ports on your Router device.

TCP port:

1025: Q.931/H.225 gatekeeper mode 1027: H.245 1045: H.245 1502: T.120 1718: Gatekeeper discovery 1720: H.323 Call Setup 1731: Audio Call Control

UDP port:

1024: RAS, adjustable 1719: Gatekeeper RAS 16384–16479: RTP/RTCP, adjustable

On SP3352, it can be configured much easier than that. Please assign a DMZ Host for VoIP then you do not have to set any port for this application.

SP3352 DMZ Host is a software emulated Host. It opens a virtual IP for user accessing from Internet. Please note that the priority of DMZ Host is lower than Virtual Sever. If you enable DMZ Host on SP3352 please do not assign any Virtual Server for other application. Thus you can avoid VoIP packets be sent to improper port to due to miss connection.

Please set DMZ Host from "Basic à DMZ" to assign a local IP for VoIP application. Save your setting and reboot it to enable the function. Please try it.

How to configure SP3352 when I use eMule?

Please set Port Forwarding to open TCP port 4662, 4711 and UDP port 4672. Save the setting then it can work fine.

68

Why can't I connect to the Web Configurator?

You can remove the proxy server settings in your web browser.

How to use Virtual Server in ADSL/Broadband Router?

Virtual Server feature allows Internet users to access standard Servers on your LAN, via the Internet IP Sharer. Normally, Internet users would not be able to access a server on your LAN because your Server does not have a valid external IP Address.

Attempts to connect to devices on your LAN are blocked by the firewall in this device. The "Virtual Server" feature solves these problems and allows Internet users to access to your servers. However, your LAN must have an existing connection to the Internet.

We can divide Virtual Server in two types. One is Port Forwarding, the other is Virtual Server. There are some standard service ports for most popular applications.

Service Port Service Port Echo 7 HTTP 80 FTP 21 PoP3 110

TELNET 23 NNTP 119 SMTP 25 SNMP 161 DNS 53 SNMP Trap 162

Finger 79

The other one is NAT Virtual Server mapping. If your ADSL account within multi-real IP Addresses then Multi -Global IP mapping function is a useful feature for Internet application. The Multi -Global IP mapping function helps you dividing the client PCs on the LAN into several groups and each group access Internet through one real IP Address. You also can set single local IP Address map to single Global IP Address. Thus it empowers the management and provides much wider application over ADSL line.

DHCP is software that automatically assigns IP addresses to client stations logging onto a TCP/IP network. DHCP eliminates having to manually assign permanent IP addresses to every device on your network. DHCP software typically runs in servers and is also found in network devices such as Routers.

DMT

Discrete Multi-Tone frequency signal modulation

71

Downstream rate

The line rate for return messages or data transfers from the network machine to the user's premises machine.

DSLAM

Digital Subscriber Line Access Multiplex

Dynamic IP Addresses

A dynamic IP address is an IP address that is automatically assigned to a client station (computer, printer, etc.) in a TCP/IP network. Dynamic IP addresses are typically assigned by a DHCP server, which can be a computer on the network or another piece of hardware, such as the Router. A dynamic IP address may change every time your computer connects to the network.

Encapsulation

The technique used by layered protocols in which a layer adds header information to the protocol data unit (PDU) from the layer above. As an example, in Internet terminology, a packet would contain a header from the physical layer, followed by a header from the network layer (IP), followed by a header from the t ransport layer (TCP), followed by the application protocol data.

Ethernet

One of the most common local area network (LAN) wiring schemes, Ethernet has a transmission rate of 10 Mbps.

FTP

Hypertext Transfer Protocol - The protocol used to carry world-wide-web (www) traffic between a www browser computer and the www server being accessed.

ICMP

Internet Control Message Protocol - The protocol used to handle errors and control messages at the IP layer. ICMP is actually part of the IP protocol.

Internet address

An IP address is assigned in blocks of numbers to user organiza tions accessing the Internet. These addresses are established by the United States Department of Defense's Network Information Center. Duplicate addresses can cause major problems on the network, but the NIC trusts organizations to use individual addresses responsibly. Each address is a 32-bit address in the form of x.x.x.x where x is an eight- bit number from 0 to 255. There are three classes: A, B and C, depending on how many computers on the site are likely to be

73

connected.

Internet Protocol (IP)

The network layer protocol for the Internet protocol suite

IP address

The 32-bit address assigned to hosts that want to participate in a TCP/IP Internet.

ISP

Internet service provider - A company allows home and corporate users to connect to the Internet.

MAC

Media Access Control Layer - A sub-layer of the Data Link Layer (Layer 2) of the ISO OSI Model responsible for media control.

MIB

Management Information Base - A collection of objects can be accessed via a network management protocol, such as SNMP and CMIP (Common Management Information Protocol).

NAT

Network Address Translation - A proposal for IP address reuse, where the local IP address is mapped to a globally unique address.

NVT

Network Virtual Terminal

PAP

Password Authentication Protocol

PORT

The abstraction used by Internet transport protocols to distinguish among multiple simultaneous connections to a single destination host.

POTS

Plain Old Telephone Service - This is the term used to describe basic telephone service.

PPP

Point-to-Point-Proto col - The successor to SLIP, PPP provides router-to-router and host-to-network connections over both synchronous and asynchronous circuits.

PPPoE

PPP over Ethernet is a protocol for connecting remote hosts to the Internet over an always-on connection by simulating a dial-up connection.

Remote server

A network computer allows a user to log on to the network from a distant location.

RFC

Request for Comments - Refers to documents published by the Internet Engineering Task Force (IETF) proposing standard protocols and procedures for the Internet. RFCs can be found at www.ietf.org..

75

Route

The path that network traffic takes from its source to its destination. The route a datagram may follow can include many gateways and many physical networks. In the Internet, each datagram is routed separately.

Router

A system responsible for making decisions about which of several paths network (or Internet) traffic will follow. To do this, it uses a routing protocol to gain information about the network and algorithms to choose the best route based on several criteria known as "routing metrics".

routing table

Information stored within a router that contains network path and status information. It is used to select the most appropriate route to forward information along.

Routing Information Protocol

Routers periodically exchange information with one another so that they can determine minimum distance paths between sources and destinations.

SNMP

Simple Network Management Protocol - The network management protocol of choice for TCP/IP-based Internet.

SOCKET

(1) The Berkeley UNIX mechanism for creating a virtual connection between processes.

(2) IBM term for software interfaces that allow two UNIX application programs to talk via TCP/IP protocols.

Spanning-Tree Bridge Protocol (STP)

Spanning-Tree Bridge Protocol (STP) - Part of an IEEE standard. A mechanism for detecting and preventing loops from occurring in a multi-bridged environment. When three or more LAN's segments are connected via bridges, a loop can occur. Because a bridge forwards all packets that are not recognized as being local, some packets can circulate for long periods of time, eventually degrading system performance. This algorithm ensures only one path connects any pair of stations, selecting one bridge as the 'root' bridge, with the highest priority one as identifier, from which all paths should radiate.

Spoofing

A method of fooling network end stations into believing that keep alive signals have come from and returned to the host. Polls are received and returned locally at either end

Static IP Addresses

A static IP address is an IP address permanently assigned to computer in a TCP/IP network. Static IP addresses are usually assigned to networked devices that are consistently accessed by multiple users, such a s Server PCs, or printers. If you are using your Router to share your cable or DSL Internet connection, contact your ISP to see if they have assigned your home a static IP address. You will need that address during your Router's configuration.

Subnet

For routing purposes, IP networks can be divided into logical subnets by using a subnet mask. Values below those of the mask are valid addresses on the subnet.

TCP

Transmission Control Protocol - The major transport protocol in the Internet suite of protocols provides reliable, connection-oriented full-duplex streams.

77

TFTP

Trivial File Transfer Protocol - A simple file transfer protocol (a simplified version of FTP) that is often used to boot diskless workstations and other network devices such as routers over a network (typically a LAN).

Telnet

The virtual terminal protocol in the Internet suite of protocols - Allows users of one host to log into a remote host and act as normal terminal users of that host.

Transparent bridging

So named because the intelligence necessary to make relaying decisions exists in the bridge itself and is thus transparent to the communicating workstations. It involves frame forwarding, learning workstation addresses and ensuring no topology loops exist (in conjunction with the Spanning-Tree algorithm).

UDP

User Datagram Protocol - A connectionless transport protocol that runs on top of TCP/IP's IP. UDP, like TCP, uses IP for delivery; however, unlike TCP, UDP provides for exchange of datagrams without acknowledgments or guaranteed delivery. Best suited for small, independent requests, such as requesting a MIB value from an SNMP agent, in which first setting up a connection would take more time than sending the data.

UNI signaling

User Network Interface signaling for ATM communications.

78

Virtual Connection (VC)

A link that seems and behaves like a dedicated point-to-point line or a system that delivers packets in sequence, as happens on an actual point-to-point network. In reality, the data is delivered across a network via the most appropriate route. The sending and receiving devices do not have to be aware of the options and the route is chosen only when a message is sent. There is no pre-arrangement, so each virtual connection exists only for the duration of that one transmission.

WAN

Wide area network - A data communications network that spans any distance and is usually provided by a public carrier (such as a telephone company or service provider).
