Advanced>UPnP Your modem is Universal Plug ‘n Play Capable, for security this feature is disabled by default. UPnP is a method of allowing devices and computer software on your Network to be able to configure ‘unblocked’ ports through your modem (and through your modem’s firewall). This makes it easier to run Network games and Programs like Microsoft Messenger etc. To Enable UPnP click the Enable UPnP box and choose the WAN connection (usually ‘PPPoE’). Select the LAN Connection (e.g.
Advanced>SNTP SNTP (Simple Network Time Protocol) allows your modem to update its time automatically using an SNTP server. To enable this feature, click the Enable SNTP tick box. YML754 Rev1 www.netcomm.com.
Option Primary, Secondary, Tertiary SNTP Servers Description This allows you to enter three different SNTP server addresses. If one of these servers is unavailable your modem will use an alternative. An example of an NTP server on the Internet is 128.250.36.3. Timeout: The number of seconds your modem will attempt to connect to an SNTP server before trying an alternative server should the server you are trying to connect to be unavailable.
Advanced>IPQoS IP QoS (Quality of Service) allows you to set priorities for traffic travelling through your modem. For example, you may want to prioritize your UDP traffic over your TCP traffic. Typical UDP traffic would be your VoIP (Voice over Internet Protocol) traffic. This section describes how to make use of your modem’s IPQoS feature. The NB5Plus4/W should have two primary sections for setting up IP QoS services: 1.
Rule definitions will be defined by the user by allowing the user to select matching based on Source IP, Destination IP, IP Protocol, Source Port, Destination Port, and Incoming Mac Port (switched LAN Port). These selections will define a rule and be associated with a particular queue priority: High, Medium, and Low.
One Expedited Forwarding (EF) Queue: High Priority queue with non-preemptible service. The EF queue is always scheduled first prior to the medium and low priority queues and runs to completion Two Queues (Medium and Low Priority) with Weighted Round Robin service. Based on the associated weights, packets on these queues share the remaining link bandwidth (after the EF service). The low priority queue corresponds to Best Effort service.
The Medium and Low priority queue lengths will be proportionally calculated via the queue weights selected in 1.) Queue Priorities above. Total queue length for all three queues will sum to the transmit queue length set in the system. Packets overflowing their queues will be tail-dropped, penalizing stochastically the greediest flow within each queue. Future implementations may introduce a “buffer stealing” policy.
The weighted values used for the WRR scheduler will be calculated based on the percentage weights the user inputs in the Web UI as stated above in 1.) Queue Priorities. Example: User selects a Medium Queue Weight = 60 %, and Low Queue Weight = 40%. Then the O(1) scheduling array will look like {L, M, M, L, M, M, L, M, M, L} where L and M represents a scheduling cycle for the respective Low and Medium queues.

getting direct access to LAN computers while still being able to access services hosted on the designated DMZ Computer. When using NAPT to share your internet connection, LAN computers will still be able to access the Internet when the DMZ host is enabled. Any direct communication to the WAN port of your Modem that is not a reply to the original NAPT request is forwarded to the DMZ host. Option Description Select your WAN Connection: Select the connection to which your DMZ client is connected to.
bers. Some applications specify a range of ports in which case you will need to know both the starting and ending port numbers in the range, which are mapped by the start port and end port fields. The Destination Port Map field specifies the internal port that the data will be directed to on the LAN Client. When dealing with port ranges, the Internal Port (designated by the Port Map field) will be the same as the first port in the range. When you simply want to forward a single port from outside (i.e.
Destination Port Start & Destination Port End. Destination Port Map: TIP: The ports on the remote client from which data is being sent to your modem’s corresponding ports. These will be the same if you are forwarding only a single port. If there is a range, then port start is the first number in the range, and port end will be the last number. This is the port number that the data should be forwarded to on the specified LAN IP (i.e. the inside port). This is usually the same as the port start figure.
table, click on the Port Forwarding menu item to return to the main Port Forwarding screen. User-created rules will be shown in the Available Rules list when the User Category radio button is selected. You can now apply the rule(s) by selecting it and clicking Add. This will add the rule to list of applied rules.
Modem Firewall. The default ‘Firewall On’ setting blocks all anonymous Internet traffic. Access control enables the user to selectively direct such traffic, for example to a Web Host in the DMZ or to specific ports opened for such applications as Web, Telnet or FTP. CAUTION: This dialog box indicates that you should not disable LAN Web Access or else you might not be able to connect to the device. If you become locked out of the device perform a Restore Factory Default as detailed earlier in this manual.
Idle Timeout: If there is no activity by the admin user logged into the modem for the number of minutes specified in this field, the user will be required to login again. Apply: Click Apply to save the changes. WARNING: It is strongly recommended that you change the default username and password to something unique. Tools>Update Firmware To update your NB5Plus4/W’s firmware, browse an update image file or configuration file and then click the Update Gateway button.

between a single sender and multiple receivers on a network. It is used when data needs to be sent from one to many devices. Typical uses might include the updat- ing of mobile personnel from a home office or the periodic publishing of an online newsletter. Multicasting provides efficiencies which enable it to use less network bandwidth than the sending of the same data by other means [e.g. SMTP]. To access Multicasting, click on Advanced>Multicast. NB5Plus4/W User Guide 58 YML754Rev1 www.netcomm.com.
To enable Multicast, open the multicast screen and select the Enable IGMP Multicast. If you have multiple connections setup on your modem you will be able to choose which connection to enable IGMP Multicast for. Click the Apply button to save the settings. Advanced > Static Routing If the Router is required to serve more than one network, you will need to set up a Static Route between the networks.
To save changes, click on Apply. Advanced>Dynamic Routing Dynamic Routing makes use of the RIP Protocol to allow the ADSL Router to automatically adjust to physical changes in the network. The NB5Plus4/W, using the RIP protocol, will determine the network packet route based on the least number of hops between the Source and the Destination. The RIP protocol regularly broadcasts routing information to other Routers on the network and is part of the IP Suite.
Select ‘In’: The NB5Plus4/W will only incorporate received RIP information. Select ‘Out’: The NB5Plus4/W will only send out RIP information. Select ‘Both’: The NB5Plus4/W will both incorporate received RIP information and send out updated RIP information. Advanced>Port Forwarding Port Forwarding is necessary because NAT [=Network Address Translation] only forwards traffic from the Internet to the LAN if a specific port mapping exists in the NAT translation table.
Thus Port Forwarding is necessary to run certain games, chat clients, video-conferencing and other kinds of applications. You might also need to configure port-forwarding if you intend to host a web server or mail server that is to be visible outside your LAN.

10BASE-T A designation for the type of wiring used by Ethernet networks with a data rate of 10 Mbps. Also known as Category 3 (CAT 3) wiring. See also data rate, Ethernet. 100BASE-T A designation for the type of wiring used by Ethernet networks with a data rate of 100 Mbps. Also known as Category 5 (CAT 5) wiring. See also data rate, Ethernet. ADSL Asymmetric Digital Subscriber Line. The most commonly deployed type of DSL for home users.
both routing and bridging. Typically, when both functions are enabled, the device routes IP data and bridges all other types of data. See also routing. broadband A telecommunications technology that can send different types of data over the same medium. DSL is a broadband technology. Broadcast To send data to all computers on a network.
Straight and crossover cable configuration There are two types of the wiring: Straight-Through Cables and Crossover Cables. Category 5 UTP/STP cable has eight wires inside the sheath. The wires form four pairs. Straight-Through Cables has same pinouts at both ends while Crossover Cables has a different pin arrangement at each end. In a straight-through cable, wires 1,2,3,4,5,6,7 and 8 at one end of the cable are still wires 1~8 at the other end.
ponent in DSL is a digital signal. See also analog. DNS Domain Name System. The DNS maps domain names into IP addresses. DNS information is distributed hierarchically throughout the Internet among computers RJ-11 Connector Pin Assignment 1 2 3 4 5 6 Normal Assignment Not Connected Not connected Line Line Not Connected Not Connected called DNS servers. When you start to access a web site, a DNS server looks up the requested domain name to find its corresponding IP address.
domain name A domain name is a user-friendly name used in place of its associated IP address. For example, www.globespan. net is the domain name associated with IP address 209.191.4.240. Domain names must be unique; their assignment is controlled by the Internet Corporation for Assigned Names and Numbers (ICANN). Domain names are a key element of URLs, which identify a specific file at a web site, e.g., http://www.globespan.net/index.html. See also DNS.
destination. Alternatively, the maximum number of hops that a packet is allowed to take before being discarded , See also TTL. host A device (usually a computer) connected to a network. HTTP Hyper-Text Transfer Protocol HTTP is the main protocol used to transfer data from web sites so that it can be displayed by web browsers. See also web browser ICMP Internet Control Message Protocol An Internet protocol used to report errors and other network-related information. The ping command makes use of ICMP.
Mbps Abbreviation for Megabits per second, or one million bits per second. Network data rates are often expressed in Mbps. Microfilter In splitterless deployments, a microfilter is a device that removes the data frequencies in the DSL signal, so that telephone users do not experience interference (noise) from the data signals. Microfilter types include in-line (installs between phone and jack) and wall-mount (telephone jack with built-in microfilter). See also splitterless.
PPP Point-to-Point Protocol A protocol for serial data transmission that is used to carry IP (and other protocol) data between your ISP and your computer. The WAN interface on the My ADSL Modem uses two forms of PPP called PPPoA and PPPoE. See also PPPoA, PPPoE. PPPoA Point-to-Point Protocol over ATM One of the two types of PPP interfaces you can define for a Virtual Circuit (VC), the other type being PPPoE. You can define only one PPPoA interface per VC.
splitterless A type of DSL installation where no splitter is installed, saving the cost of a service call by the telephone company. Instead, each jack in the home carries both voice and data, requiring a microfilter for each telephone to prevent interference from the data signal. ADSL is usually splitterless; if you are unsure if your installation has a splitter, ask your DSL provider. See also splitter, microfilter. subnet A subnet is a portion of a network.
Internet. USB Universal Serial Bus A serial interface that lets you connect devices such as printers, scanners, etc. to your computer by simply plugging them in. The My ADSL Modem is equipped with a USB interface for connecting to a standalone PC. VC Virtual Circuit A connection from your ADSL router to your ISP. VCI Virtual Circuit Identifier Together with the Virtual Path Identifier (VPI), the VCI uniquely identifies a VC. Your ISP will tell you the VCI for each VC they provide. See also VC.
