3.5.2 ATM Settings The page is for ATM PVCs’ QoS mode setting. The device supports 4 QoS mode — UBR / CBR /rt-VBR / nrt-VBR. You can click the “ATM Setting” on the WAN Interface setting screen. ATM QoS: Select the Quality of Service types for this Virtual Circuit. The ATM QoS types include CBR(Constant Bit Rate), VBR(Variable Bit Rate) and UBR (Unspecified Bit Rate). These QoS types are all controlled by the parameters specified below, including PCR, SCR, and MBS. CBR is for connections that support constant rates of data transfer. The only parameter you need to worry about in CBR is PCR. UBR is for connections that have variable traffic. The only parameter you need to worry about in UBR is PCR. rt-VBR is for connections that, while having variable traffic, require precise timing between traffic source and destination. PCR, SCR and MBS must all be set for rt-VBR. nrt-VBR is for connections that have variable traffic, do not require precise timing, but still require a set bandwidth availability. PCR, SCR and MBS must all be set for nrt-VBR. PCR: Peak Cell Rate (PCR) is the maximum rate at which the sender can send cells. This parameter may be lower (but not higher) than the maximum line speed. 1 ATM cell is 53 bytes (424 bits), so a maximum speed of 832 Kbps gives a maximum PCR of 1962 cells/sec. This rate is not guaranteed because it is dependent on the line speed. 39
SCR: Sustained Cell Rate (SCR) is the mean cell rate of a bursty, on-off traffic source that can be sent at the peak rate, and a parameter for burst-type traffic. SCR may not be greater than the PCR; the system default is 0 cells/sec. MBS: Maximum Burst Size (MBS) is the maximum number of cells that can be sent at the PCR. After MBS is reached, cell rates fall below SCR until cell rate averages to the SCR again. At this time, more cells (up to the MBS) can be sent at the PCR again. “Apply Changes”: Set new PVC QoS mode and values for the selected PVC. “Undo”: Discard your settings. 3.5.3 ADSL Settings You can set ADSL connect mode here.

Appendix A: Glossary Address mask A bit mask select bits from an Internet address for subnet addressing. The mask is 32 bits long and selects the network portion of the Internet address and one or more bits of the local portion. Sometimes it called subnet mask. AAL5 ATM Adaptation Layer - This layer maps higher layer user data into ATM cells, making the data suitable for transport through the ATM network. ADSL Asymmetric digital subscriber line ATM Asynchronous Transfer Mode - A cell-based data transfer technique in which channel demand determines packet allocation. ATM offers fast packet technology, real time, and demand led switching for efficient use of network resources. AWG American Wire Gauge - The measurement of thickness of a wire Bridge A device connects two or more physical networks and forward packets between them. Bridges can usually be made to filter packets, that is, to forward only certain traffic. Related devices are repeaters which simply forward electrical signals from one cable to the other and full-fledged routers which make routing decisions based on several criteria. Broadband Characteristic of any network multiplexes independent network carriers onto a single cable. Broadband technology allows several networks to coexist on one single cable; traffic from one network does not interfere with traffic from another.

Refers to equipment located at a Telco or service provider's office. CPE Customer Premises Equipment located in a user's premises 65
66DHCP (Dynamic Host Configuration Protocol) 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 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 layer 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 transport layer (TCP), and 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 File Transfer Protocol. The Internet protocol (and program) transfer files between hosts. Hop count A measure of distance between two points on the Internet. It is equivalent to the number of gateways that separate the source and destination.
HTML Hypertext Markup Language - The page-coding language for the World Wide Web. HTML browser A browser used to traverse the Internet, such as Netscape or Microsoft Internet Explorer. http Hypertext Transfer Protocol - The protocol carry world-wide-web (www) traffic between a www browser computer and the www server being accessed. ICMP Internet Control Message Protocol - The protocol 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 organizations 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 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. 67
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 in Internet transport protocols to distinguish among multiple simultaneous connections to a single destination host. POTS Plain Old Telephone Service - This is the term describe basic telephone service. PPP Point-to-Point-Protocol - 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. RFC can be found at www.ietf.org. 68
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 is 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 of 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. 69
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 Address 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 as 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. TFTP Trivial File Transfer Protocol. A simple file transfer protocol (a simplified version of FTP) that is often 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 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 datagram without acknowledgments or guaranteed delivery. Best suited for small, independent requests, such as requesting a MIB value from an SNMP agent, in which first 70

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).
Important Note According to Annex3 of the ERC/REC 70-03 publication, the use of Wideband Data Transmission systems has the following National Restrictions: Frequency range: 2400-2483.5MHz Country Restriction Reason/Remark France Outdoor use limited to 10 mW e.i.r.p. within the band 2454-2483.5 MHz Military Radiolocation use. Refarming of the 2.4 GHz band has been ongoing in recent years to allow current relaxed regulation. Full implementation planned 2012 Italy If used outside of own premises, general authorization is required Luxembourg None General authorization required for network and service supply(not for spectrum) Norway Implemented This subsection does not apply for the geographical area within a radius of 20km from the centre of Ny-Alesund Russian Federation Only for indoor applications 72
