Chapter 16Bandwidth ManagementNBG4604 User’s Guide14816.3  What You Need To KnowYou can limit an application’s uplink or downlink bandwidth. This limit keeps the traffic from using up too much of the out-going interface’s bandwidth. This way you can make sure there is bandwidth for other applications. Use the following guidelines:•The sum of the bandwidth allotments that apply to the WAN interface (LAN to WAN, WLAN to WAN) must be less than or equal to the Uplink value that you configure in the Bandwidth ManagementGeneral screen. •The sum of the bandwidth allotments that apply to the LAN port (WAN to LAN, WAN to WLAN) must be less than or equal to the Downlink value that you configure in the Bandwidth ManagementGeneral screen.  16.4   General Configuration Use this screen to enable bandwidth management and assign uplink/downlink limits. You can use either one of the following types:•Priority Queue. Enable bandwidth management to give uplink traffic that matches a bandwidth rule priority over traffic that does not match a bandwidth rule. (This type does not apply to downlink traffic.)  •Bandwidth Allocation. Enabling bandwidth management also allows you to control the maximum or minimum amounts of bandwidth that can be used by traffic that matches a bandwidth rule.Note: You cannot apply both bandwidth management types at the same time.Click Management> Bandwidth MGMT to open the bandwidth management General screen.Figure 82   Management > Bandwidth MGMT > GeneralCompany Confidential

NBG4604 User’s Guide 159CHAPTER 18Universal Plug-and-Play (UPnP)18.1  Overview This chapter introduces the UPnP feature in the Web Configurator.Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP for simple peer-to-peer network connectivity between devices. A UPnP device can dynamically join a network, obtain an IP address, convey its capabilities and learn about other devices on the network. In turn, a device can leave a network smoothly and automatically when it is no longer in use.18.2  What You Can DoUse the UPnP screen (Section 18.4 on page 160) to enable UPnP on the NBG4604.18.3  What You Need to KnowHow do I know if I'm using UPnP? UPnP hardware is identified as an icon in the Network Connections folder (Windows XP). Each UPnP compatible device installed on your network will appear as a separate icon. Selecting the icon of a UPnP device will allow you to access the information and properties of that device. NAT TraversalUPnP NAT traversal automates the process of allowing an application to operate through NAT. UPnP network devices can automatically configure network addressing, announce their presence in the network to other UPnP devices and enable exchange of simple product and service descriptions. NAT traversal allows the following:Company Confidential
Chapter 18Universal Plug-and-Play (UPnP)NBG4604 User’s Guide160•Dynamic port mapping•Learning public IP addresses•Assigning lease times to mappingsWindows Messenger is an example of an application that supports NAT traversal and UPnP. See the NAT chapter for more information on NAT.Cautions with UPnPThe automated nature of NAT traversal applications in establishing their own services and opening firewall ports may present network security issues. Network information and configuration may also be obtained and modified by users in some network environments. When a UPnP device joins a network, it announces its presence with a multicast message. For security reasons, the NBG4604 allows multicast messages on the LAN only.All UPnP-enabled devices may communicate freely with each other without additional configuration. Disable UPnP if this is not your intention. 18.4  UPnP ScreenUse this screen to enable UPnP.

NBG4604 User’s Guide 167CHAPTER 19SNMP19.1  OverviewSimple Network Management Protocol (SNMP) is a protocol for collecting and managing information about network devices. Your NBG4604 supports SNMP agent functionality, which allows a manager station to manage and monitor the NBG4604 through the network. The NBG4604 supports SNMP version one (SNMPv1) and version two (SNMPv2c).Note: Only configure the SNMP feature with settings provided by your ISP.19.2  What You Need to KnowAn SNMP managed network consists of two main types of component: agents and a manager. Figure 96   SNMP Management ModelCompany Confidential
Chapter 19SNMPNBG4604 User’s Guide168An agent is a management software module that resides in a managed device (the NBG4604). An agent translates the local management information from the managed device into a form compatible with SNMP. The manager is the console through which network administrators perform network management functions. It executes applications that control and monitor managed devices. The managed devices contain object variables/managed objects that define each piece of information to be collected about a device. Examples of variables include such as number of packets received, node port status etc. A Management Information Base (MIB) is a collection of managed objects. SNMP allows a manager and agents to communicate for the purpose of accessing these objects.SNMP itself is a simple request/response protocol based on the manager/agent model. The manager issues a request and the agent returns responses using the following protocol operations:•Get - Allows the manager to retrieve an object variable from the agent. •GetNext - Allows the manager to retrieve the next object variable from a table or list within an agent. In SNMPv1, when a manager wants to retrieve all elements of a table from an agent, it initiates a Get operation, followed by a series of GetNext operations. •Set - Allows the manager to set values for object variables within an agent. •Trap - Used by the agent to inform the manager of some events.19.3  SNMP ScreenUse this screen to enable SNMP.

NBG4604 User’s Guide 171CHAPTER 20ACS20.1  OverviewThis chapter shows you to configure the NBG4604’s ACS settings so that it can be remotely configured by an Auto-Configuration Server (ACS).An administrator can use an ACS to remotely set up the NBG4604, modify its settings, perform firmware upgrades, and monitor and diagnose it. In order to do so, you must enable the TR-069 feature on your NBG4604 and then configure it appropriately. (The ACS server which it will use must also be configured by its administrator.)20.2  What You Can Do in this Chapter•Use the General screen (Section 20.4 on page 172) to configure set up the ACS server information on your NBG4604.•Use the Certificate screen (Section 20.5 on page 175) to upload encrypted security certificates to your NBG4604.20.3  What You Need to KnowThe following terms and concepts may help as you read this chapter.ACSAn Auto-Configuration Server (ACS) centralizes the management and configuration of a variety of networking devices such as routers, set-top boxes, Voice over IP (VoIP) gateways, and other Customer Premises Equipment (CPE). It is based on the TR-069 standard.Company Confidential

The OUI field is the first three octets in a MAC address and uniquely identifies the manufacturer of a network device.STUNSTUN allows a device to find the public IP address assigned by a NAT router and/or a firewall between it and the public Internet.20.4  General ScreenThe General screen allows you to set up the ACS server information on your NBG4604 so it can be remotely updated. Only use information provided by your network administrator.20.4.1  STUNSTUN (Simple Traversal of User Datagram Protocol (UDP) through Network Address Translators) allows the NBG4604 to find the presence and types of NAT routers and/or firewalls between it and the public Internet. STUN also allows the NBG4604 to find the public IP address that NAT assigned, so the NBG4604 can embed it in the SIP data stream. STUN does not work with symmetric NAT routers or firewalls. See RFC 3489 for details on STUN.The following figure shows how STUN works. 1The NBG4604 (A) sends SIP packets to the STUN server (B).2The STUN server (B) finds the public IP address and port number that the NAT router used on the NBG4604’s SIP packets and sends them to the NBG4604.Company Confidential

Chapter 20ACSNBG4604 User’s Guide17620.6  Technical ReferenceTR-069 is an abbreviation of “Technical Reference 069”, a protocol designed to facilitate the remote management of Customer Premise Equipement (CPE), such as the NBG4604. It can be managed over a WAN by means of an Auto Configuration Server (ACS). TR-069 is based on sending Remote Procedure Calls (RPCs) between the ACS and the client device. RPCs are sent in Extensible Markup Language (XML) format over HTTP or HTTPS. Figure 101   TR-069 ExampleIn this example, the NBG4604 receives data from at least 3 sources: A SIP server for handling voice calls, an HTTP server for handling web services, and an ACS, for configuring the NBG4604 remotely. All three servers are owned and operated by the client’s Internet Service Provider. However, without the configuration settings from the ACS, the NBG4604 cannot access the other two servers. Once the NBG4604 receives its configuration settings and implements them, it can connect to the other servers. If the settings change, it will once again be unable to connect until it receives its updates from the ACS.The NBG4604 can be configured to periodically check for updates from the auto-configuration server so that the end user need not be worried about it.SIPACSHTTPCompany Confidential

NBG4604 User’s Guide 211APPENDIX  A IP Addresses and SubnettingThis appendix introduces IP addresses and subnet masks. IP addresses identify individual devices on a network. Every networking device (including computers, servers, routers, printers, etc.) needs an IP address to communicate across the network. These networking devices are also known as hosts.Subnet masks determine the maximum number of possible hosts on a network. You can also use subnet masks to divide one network into multiple sub-networks.Introduction to IP AddressesOne part of the IP address is the network number, and the other part is the host ID. In the same way that houses on a street share a common street name, the hosts on a network share a common network number. Similarly, as each house has its own house number, each host on the network has its own unique identifying number - the host ID. Routers use the network number to send packets to the correct network, while the host ID determines to which host on the network the packets are delivered.StructureAn IP address is made up of four parts, written in dotted decimal notation (for example, 192.168.1.1). Each of these four parts is known as an octet. An octet is an eight-digit binary number (for example 11000000, which is 192 in decimal notation). Therefore, each octet has a possible range of 00000000 to 11111111 in binary, or 0 to 255 in decimal.Company Confidential
Appendix AIP Addresses and SubnettingNBG4604 User’s Guide212The following figure shows an example IP address in which the first three octets (192.168.1) are the network number, and the fourth octet (16) is the host ID.Figure 123   Network Number and Host IDHow much of the IP address is the network number and how much is the host ID varies according to the subnet mask. Subnet MasksA subnet mask is used to determine which bits are part of the network number, and which bits are part of the host ID (using a logical AND operation). The term “subnet” is short for “sub-network”.A subnet mask has 32 bits. If a bit in the subnet mask is a “1” then the corresponding bit in the IP address is part of the network number. If a bit in the subnet mask is “0” then the corresponding bit in the IP address is part of the host ID. The following example shows a subnet mask identifying the network number (in bold text) and host ID of an IP address (192.168.1.2 in decimal).Table 73   Subnet Mask - Identifying Network Number1STOCTET:(192)2NDOCTET:(168)3RDOCTET:(1)4TH OCTET(2)IP Address (Binary)11000000101010000000000100000010Subnet Mask (Binary) 111111111111111111111111 00000000Company Confidential
 Appendix AIP Addresses and SubnettingNBG4604 User’s Guide 213By convention, subnet masks always consist of a continuous sequence of ones beginning from the leftmost bit of the mask, followed by a continuous sequence of zeros, for a total number of 32 bits.Subnet masks can be referred to by the size of the network number part (the bits with a “1” value). For example, an “8-bit mask” means that the first 8 bits of the mask are ones and the remaining 24 bits are zeroes.Subnet masks are expressed in dotted decimal notation just like IP addresses. The following examples show the binary and decimal notation for 8-bit, 16-bit, 24-bit and 29-bit subnet masks. Network SizeThe size of the network number determines the maximum number of possible hosts you can have on your network. The larger the number of network number bits, the smaller the number of remaining host ID bits. An IP address with host IDs of all zeros is the IP address of the network (192.168.1.0 with a 24-bit subnet mask, for example). An IP address with host IDs of all ones is the broadcast address for that network  (192.168.1.255 with a 24-bit subnet mask, for example).Network Number 110000001010100000000001Host ID00000010Table 74   Subnet MasksBINARYDECIMAL1STOCTET 2NDOCTET 3RDOCTET 4THOCTET8-bit mask 11111111 00000000 00000000 00000000 255.0.0.016-bitmask 11111111 11111111 00000000 00000000 255.255.0.024-bitmask 11111111 11111111 11111111 00000000 255.255.255.029-bitmask 11111111 11111111 11111111 11111000 255.255.255.248Table 73   Subnet Mask - Identifying Network Number1STOCTET:(192)2NDOCTET:(168)3RDOCTET:(1)4TH OCTET(2)Company Confidential
Appendix AIP Addresses and SubnettingNBG4604 User’s Guide214As these two IP addresses cannot be used for individual hosts, calculate the maximum number of possible hosts in a network as follows:NotationSince the mask is always a continuous number of ones beginning from the left, followed by a continuous number of zeros for the remainder of the 32 bit mask, you can simply specify the number of ones instead of writing the value of each octet. This is usually specified by writing a “/” followed by the number of bits in the mask after the address. For example, 192.1.1.0 /25 is equivalent to saying 192.1.1.0 with subnet mask 255.255.255.128. The following table shows some possible subnet masks using both notations.

 Appendix AIP Addresses and SubnettingNBG4604 User’s Guide 215SubnettingYou can use subnetting to divide one network into multiple sub-networks. In the following example a network administrator creates two sub-networks to isolate a group of servers from the rest of the company network for security reasons.In this example, the company network address is 192.168.1.0. The first three octets of the address (192.168.1) are the network number, and the remaining octet is the host ID, allowing a maximum of 28 – 2 or 254 possible hosts.The following figure shows the company network before subnetting.  Figure 124   Subnetting Example: Before SubnettingYou can “borrow” one of the host ID bits to divide the network 192.168.1.0 into two separate sub-networks. The subnet mask is now 25 bits (255.255.255.128 or /25).The “borrowed” host ID bit can have a value of either 0 or 1, allowing two subnets; 192.168.1.0 /25 and 192.168.1.128 /25. Company Confidential
Appendix AIP Addresses and SubnettingNBG4604 User’s Guide216The following figure shows the company network after subnetting. There are now two sub-networks, A and B.Figure 125   Subnetting Example: After SubnettingIn a 25-bit subnet the host ID has 7 bits, so each sub-network has a maximum of 27 – 2 or 126 possible hosts (a host ID of all zeroes is the subnet’s address itself, all ones is the subnet’s broadcast address).192.168.1.0 with mask 255.255.255.128 is subnet A itself, and 192.168.1.127 with mask 255.255.255.128 is its broadcast address. Therefore, the lowest IP address that can be assigned to an actual host for subnet A is 192.168.1.1 and the highest is 192.168.1.126. Similarly, the host ID range for subnet B is 192.168.1.129 to 192.168.1.254.Example: Four Subnets The previous example illustrated using a 25-bit subnet mask to divide a 24-bit address into two subnets. Similarly, to divide a 24-bit address into four subnets, you need to “borrow” two host ID bits to give four possible combinations (00, 01, 10 and 11). The subnet mask is 26 bits (11111111.11111111.11111111.11000000) or 255.255.255.192. Company Confidential

 Appendix AIP Addresses and SubnettingNBG4604 User’s Guide 219The following table is a summary for subnet planning on a network with a 16-bit network number. Configuring IP AddressesWhere you obtain your network number depends on your particular situation. If the ISP or your network administrator assigns you a block of registered IP addresses, follow their instructions in selecting the IP addresses and the subnet mask.If the ISP did not explicitly give you an IP network number, then most likely you have a single user account and the ISP will assign you a dynamic IP address when the connection is established. If this is the case, it is recommended that you select a network number from 192.168.0.0 to 192.168.255.0. The Internet Assigned Number Authority (IANA) reserved this block of addresses specifically for private use; please do not use any other number unless you are told otherwise. You must also enable Network Address Translation (NAT) on the NBG4604. Once you have decided on the network number, pick an IP address for your NBG4604 that is easy to remember (for instance, 192.168.1.1) but make sure that no other device on your network is using that IP address.The subnet mask specifies the network number portion of an IP address.

You don't need to change the subnet mask computed by the NBG4604 unless you are instructed to do otherwise.Private IP AddressesEvery machine on the Internet must have a unique address. If your networks are isolated from the Internet (running only between two branch offices, for example) you can assign any IP addresses to the hosts without problems. However, the Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of IP addresses specifically for private networks:•10.0.0.0     — 10.255.255.255•172.16.0.0   — 172.31.255.255•192.168.0.0 — 192.168.255.255You can obtain your IP address from the IANA, from an ISP, or it can be assigned from a private network. If you belong to a small organization and your Internet access is through an ISP, the ISP can provide you with the Internet addresses for your local networks. On the other hand, if you are part of a much larger organization, you should consult your network administrator for the appropriate IP addresses.Regardless of your particular situation, do not create an arbitrary IP address; always follow the guidelines above. For more information on address assignment, please refer to RFC 1597, Address Allocation for Private Internets and RFC 1466, Guidelines for Management of IP Address Space.Company Confidential

NBG4604 User’s Guide 247APPENDIX  D Wireless LANsWireless LAN TopologiesThis section discusses ad-hoc and infrastructure wireless LAN topologies.Ad-hoc Wireless LAN ConfigurationThe simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects a set of computers with wireless stations (A, B, C). Any time two or more wireless adapters are within range of each other, they can set up an independent network, which is commonly referred to as an Ad-hoc network or Independent Basic Service Set (IBSS). The following diagram shows an example of notebook computers using wireless adapters to form an Ad-hoc wireless LAN. Figure 157   Peer-to-Peer Communication in an Ad-hoc NetworkBSSA Basic Service Set (BSS) exists when all communications between wireless stations or between a wireless station and a wired network client go through one access point (AP). Intra-BSS traffic is traffic between wireless stations in the BSS. When Intra-BSS is enabled, wireless station A and B can access the wired network and communicate Company Confidential
Appendix DWireless LANsNBG4604 User’s Guide248with each other. When Intra-BSS is disabled, wireless station A and B can still access the wired network but cannot communicate with each other.Figure 158   Basic Service SetESSAn Extended Service Set (ESS) consists of a series of overlapping BSSs, each containing an access point, with each access point connected together by a wired network. This wired connection between APs is called a Distribution System (DS).This type of wireless LAN topology is called an Infrastructure WLAN. The Access Points not only provide communication with the wired network but also mediate wireless network traffic in the immediate neighborhood. Company Confidential
 Appendix DWireless LANsNBG4604 User’s Guide 249An ESSID (ESS IDentification) uniquely identifies each ESS. All access points and their associated wireless stations within the same ESS must have the same ESSID in order to communicate.Figure 159   Infrastructure WLANChannelA channel is the radio frequency(ies) used by IEEE 802.11a/b/g wireless devices. Channels available depend on your geographical area. You may have a choice of channels (for your region) so you should use a different channel than an adjacent AP (access point) to reduce interference. Interference occurs when radio signals from different access points overlap causing interference and degrading performance.Adjacent channels partially overlap however. To avoid interference due to overlap, your AP should be on a channel at least five channels away from a channel that an adjacent AP is using. For example, if your region has 11 channels and an adjacent AP is using channel 1, then you need to select a channel between 6 or 11.RTS/CTSA hidden node occurs when two stations are within range of the same access point, but are not within range of each other. The following figure illustrates a hidden node. Both stations (STA) are within range of the access point (AP) or Company Confidential
Appendix DWireless LANsNBG4604 User’s Guide250wireless gateway, but out-of-range of each other, so they cannot "hear" each other, that is they do not know if the channel is currently being used. Therefore, they are considered hidden from each other. Figure 160    RTS/CTSWhen station A sends data to the AP, it might not know that the station B is already using the channel. If these two stations send data at the same time, collisions may occur when both sets of data arrive at the AP at the same time, resulting in a loss of messages for both stations.RTS/CTS is designed to prevent collisions due to hidden nodes. An RTS/CTS defines the biggest size data frame you can send before an RTS (Request To Send)/CTS (Clear to Send) handshake is invoked.When a data frame exceeds the RTS/CTS value you set (between 0 to 2432 bytes), the station that wants to transmit this frame must first send an RTS (Request To Send) message to the AP for permission to send it. The AP then responds with a CTS (Clear to Send) message to all other stations within its range to notify them to defer their transmission. It also reserves and confirms with the requesting station the time frame for the requested transmission.Stations can send frames smaller than the specified RTS/CTS directly to the AP without the RTS (Request To Send)/CTS (Clear to Send) handshake. You should only configure RTS/CTS if the possibility of hidden nodes exists on your network and the "cost" of resending large frames is more than the extra network overhead involved in the RTS (Request To Send)/CTS (Clear to Send) handshake. If the RTS/CTS value is greater than the Fragmentation Threshold value (see next), then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented before they reach RTS/CTS size. Note: Enabling the RTS Threshold causes redundant network overhead that could negatively affect the throughput performance instead of providing a remedy.Company Confidential
 Appendix DWireless LANsNBG4604 User’s Guide 251Fragmentation ThresholdAFragmentation Threshold is the maximum data fragment size (between 256 and 2432 bytes) that can be sent in the wireless network before the AP will fragment the packet into smaller data frames.A large Fragmentation Threshold is recommended for networks not prone to interference while you should set a smaller threshold for busy networks or networks that are prone to interference.If the Fragmentation Threshold value is smaller than the RTS/CTS value (see previously) you set then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented before they reach RTS/CTS size.Preamble TypeA preamble is used to synchronize the transmission timing in your wireless network. There are two preamble modes: Long and Short.Short preamble takes less time to process and minimizes overhead, so it should be used in a good wireless network environment when all wireless stations support it. Select Long if you have a ‘noisy’ network or are unsure of what preamble mode your wireless stations support as all IEEE 802.11b compliant wireless adapters must support long preamble. However, not all wireless adapters support short preamble. Use long preamble if you are unsure what preamble mode the wireless adapters support, to ensure interpretability between the AP and the wireless stations and to provide more reliable communication in ‘noisy’ networks. Select Dynamic to have the AP automatically use short preamble when all wireless stations support it, otherwise the AP uses long preamble.Note: The AP and the wireless stations MUSTuse the same preamble mode in order to communicate.IEEE 802.11g Wireless LANIEEE 802.11g is fully compatible with the IEEE 802.11b standard. This means an IEEE 802.11b adapter can interface directly with an IEEE 802.11g access point (and vice versa) at 11 Mbps or lower depending on range. IEEE 802.11g has Company Confidential
Appendix DWireless LANsNBG4604 User’s Guide252several intermediate rate steps between the maximum and minimum data rates. The IEEE 802.11g data rate and modulation are as follows:IEEE 802.1xIn June 2001, the IEEE 802.1x standard was designed to extend the features of IEEE 802.11 to support extended authentication as well as providing additional accounting and control features. It is supported by Windows XP and a number of network devices. Some advantages of IEEE 802.1x are:•User based identification that allows for roaming.•Support for RADIUS (Remote Authentication Dial In User Service, RFC 2138, 2139) for centralized user profile and accounting management on a network RADIUS server. •Support for EAP (Extensible Authentication Protocol, RFC 2486) that allows additional authentication methods to be deployed with no changes to the access point or the wireless stations. RADIUSRADIUS is based on a client-server model that supports authentication, authorization and accounting. The access point is the client and the server is the RADIUS server. The RADIUS server handles the following tasks:•Authentication Determines the identity of the users.•AuthorizationDetermines the network services available to authenticated users once they are connected to the network.•AccountingKeeps track of the client’s network activity. RADIUS is a simple package exchange in which your AP acts as a message relay between the wireless station and the network RADIUS server.

 Appendix DWireless LANsNBG4604 User’s Guide 253Types of RADIUS MessagesThe following types of RADIUS messages are exchanged between the access point and the RADIUS server for user authentication:•Access-RequestSent by an access point requesting authentication.•Access-RejectSent by a RADIUS server rejecting access.•Access-AcceptSent by a RADIUS server allowing access. •Access-ChallengeSent by a RADIUS server requesting more information in order to allow access. The access point sends a proper response from the user and then sends another Access-Request message. The following types of RADIUS messages are exchanged between the access point and the RADIUS server for user accounting:•Accounting-RequestSent by the access point requesting accounting.•Accounting-ResponseSent by the RADIUS server to indicate that it has started or stopped accounting. In order to ensure network security, the access point and the RADIUS server use a shared secret key, which is a password, they both know. The key is not sent over the network. In addition to the shared key, password information exchanged is also encrypted to protect the network from unauthorized access. Types of Authentication This appendix discusses some popular authentication types: EAP-MD5,EAP-TLS,EAP-TTLS,PEAP and LEAP.The type of authentication you use depends on the RADIUS server or the AP. Consult your network administrator for more information.EAP-MD5 (Message-Digest Algorithm 5)MD5 authentication is the simplest one-way authentication method. The authentication server sends a challenge to the wireless station. The wireless station ‘proves’ that it knows the password by encrypting the password with the challenge and sends back the information. Password is not sent in plain text. Company Confidential
Appendix DWireless LANsNBG4604 User’s Guide254However, MD5 authentication has some weaknesses. Since the authentication server needs to get the plaintext passwords, the passwords must be stored. Thus someone other than the authentication server may access the password file. In addition, it is possible to impersonate an authentication server as MD5 authentication method does not perform mutual authentication. Finally, MD5 authentication method does not support data encryption with dynamic session key. You must configure WEP encryption keys for data encryption. EAP-TLS (Transport Layer Security)With EAP-TLS, digital certifications are needed by both the server and the wireless stations for mutual authentication. The server presents a certificate to the client. After validating the identity of the server, the client sends a different certificate to the server. The exchange of certificates is done in the open before a secured tunnel is created. This makes user identity vulnerable to passive attacks. A digital certificate is an electronic ID card that authenticates the sender’s identity. However, to implement EAP-TLS, you need a Certificate Authority (CA) to handle certificates, which imposes a management overhead. EAP-TTLS (Tunneled Transport Layer Service) EAP-TTLS is an extension of the EAP-TLS authentication that uses certificates for only the server-side authentications to establish a secure connection. Client authentication is then done by sending username and password through the secure connection, thus client identity is protected. For client authentication, EAP-TTLS supports EAP methods and legacy authentication methods such as PAP, CHAP, MS-CHAP and MS-CHAP v2. PEAP (Protected EAP)Like EAP-TTLS, server-side certificate authentication is used to establish a secure connection, then use simple username and password methods through the secured connection to authenticate the clients, thus hiding client identity. However, PEAP only supports EAP methods, such as EAP-MD5, EAP-MSCHAPv2 and EAP-GTC (EAP-Generic Token Card), for client authentication. EAP-GTC is implemented only by Cisco.LEAPLEAP (Lightweight Extensible Authentication Protocol) is a Cisco implementation of IEEE 802.1x. Dynamic WEP Key ExchangeThe AP maps a unique key that is generated with the RADIUS server. This key expires when the wireless connection times out, disconnects or reauthentication times out. A new WEP key is generated each time reauthentication is performed.Company Confidential
 Appendix DWireless LANsNBG4604 User’s Guide 255If this feature is enabled, it is not necessary to configure a default encryption key in the Wireless screen. You may still configure and store keys here, but they will not be used while Dynamic WEP is enabled.Note: EAP-MD5 cannot be used with dynamic WEP key exchangeFor added security, certificate-based authentications (EAP-TLS, EAP-TTLS and PEAP) use dynamic keys for data encryption. They are often deployed in corporate environments, but for public deployment, a simple user name and password pair is more practical. The following table is a comparison of the features of authentication types.WPA(2)Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption, authentication and key management than WPA. Key differences between WPA(2) and WEP are improved data encryption and user authentication.    EncryptionBoth WPA and WPA2 improve data encryption by using Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC) and IEEE 802.1x. In addition to TKIP, WPA2 also uses Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining Message authentication code Protocol (CCMP) to offer stronger encryption. Temporal Key Integrity Protocol (TKIP) uses 128-bit keys that are dynamically generated and distributed by the authentication server. It includes a per-packet key mixing function, a Message Integrity Check (MIC) named Michael, an extended initialization vector (IV) with sequencing rules, and a re-keying mechanism.Table 85   Comparison of EAP Authentication TypesEAP-MD5 EAP-TLS EAP-TTLS PEAP LEAPMutual Authentication No Yes Yes Yes YesCertificate – Client No Yes Optional Optional NoCertificate – Server No Yes Yes Yes NoDynamic Key Exchange No Yes Yes Yes YesCredential Integrity None Strong Strong Strong ModerateDeployment Difficulty Easy Hard Moderate Moderate ModerateClient Identity Protection No No Yes Yes NoCompany Confidential
Appendix DWireless LANsNBG4604 User’s Guide256TKIP regularly changes and rotates the encryption keys so that the same encryption key is never used twice. The RADIUS server distributes a Pairwise Master Key (PMK) key to the AP that then sets up a key hierarchy and management system, using the pair-wise key to dynamically generate unique data encryption keys to encrypt every data packet that is wirelessly communicated between the AP and the wireless clients. This all happens in the background automatically.WPA2 AES (Advanced Encryption Standard) is a block cipher that uses a 256-bit mathematical algorithm called Rijndael.The Message Integrity Check (MIC) is designed to prevent an attacker from capturing data packets, altering them and resending them. The MIC provides a strong mathematical function in which the receiver and the transmitter each compute and then compare the MIC. If they do not match, it is assumed that the data has been tampered with and the packet is dropped. By generating unique data encryption keys for every data packet and by creating an integrity checking mechanism (MIC), TKIP makes it much more difficult to decode data on a Wi-Fi network than WEP, making it difficult for an intruder to break into the network. The encryption mechanisms used for WPA and WPA-PSK are the same. The only difference between the two is that WPA-PSK uses a simple common password, instead of user-specific credentials. The common-password approach makes WPA-PSK susceptible to brute-force password-guessing attacks but it's still an improvement over WEP as it employs an easier-to-use, consistent, single, alphanumeric password.  User AuthenticationWPA or WPA2 applies IEEE 802.1x and Extensible Authentication Protocol (EAP) to authenticate wireless clients using an external RADIUS database. If both an AP and the wireless clients support WPA2 and you have an external RADIUS server, use WPA2 for stronger data encryption. If you don't have an external RADIUS server, you should use WPA2 -PSK (WPA2 -Pre-Shared Key) that only requires a single (identical) password entered into each access point, wireless gateway and wireless client. As long as the passwords match, a wireless client will be granted access to a WLAN. If the AP or the wireless clients do not support WPA2, just use WPA or WPA-PSK depending on whether you have an external RADIUS server or not.Select WEP only when the AP and/or wireless clients do not support WPA or WPA2. WEP is less secure than WPA or WPA2.Company Confidential
 Appendix DWireless LANsNBG4604 User’s Guide 25727.1.2  WPA(2)-PSK Application ExampleA WPA(2)-PSK application looks as follows.1First enter identical passwords into the AP and all wireless clients. The Pre-Shared Key (PSK) must consist of between 8 and 63 ASCII characters (including spaces and symbols).2The AP checks each wireless client's password and (only) allows it to join the network if the password matches.3The AP derives and distributes keys to the wireless clients.4The AP and wireless clients use the TKIP or AES encryption process to encrypt data exchanged between them.Figure 161   WPA(2)-PSK Authentication27.1.3  WPA(2) with RADIUS Application ExampleYou need the IP address of the RADIUS server, its port number (default is 1812), and the RADIUS shared secret. A WPA(2) application example with an external RADIUS server looks as follows. "A" is the RADIUS server. "DS" is the distribution system.1The AP passes the wireless client's authentication request to the RADIUS server.2The RADIUS server then checks the user's identification against its database and grants or denies network access accordingly.3The RADIUS server distributes a Pairwise Master Key (PMK) key to the AP that then sets up a key hierarchy and management system, using the pair-wise key to dynamically generate unique data encryption keys to encrypt every data packet that is wirelessly communicated between the AP and the wireless clients.

 Appendix FOpen Software AnnouncementsSTB-2101H User’s Guide 267PreambleThe licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Pub-lic License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all itsusers. This General Public License applies to most of the Free Software Foundation's software and to any other program whoseauthors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General PublicLicense instead.) You can apply it to your programs, too.When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make surethat you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive sourcecode or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know youcan do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender therights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it.For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights thatyou have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so theyknow their rights.We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permissionto copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyoneunderstands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want itsrecipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the originalauthors' reputations.Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a freeprogram will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clearthat any patent must be licensed for everyone's free use or not licensed at all.The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be dis-tributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "workbased on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing theProgram or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translationis included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, dis-tribution and modification are not covered by this License; they are outside its scope. The act of running the Program is notrestricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent ofhaving been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that youconspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact allthe notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy ofthis License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your optionoffer warranty protection in exchange for a fee.2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copyand distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions:a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change.b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or anypart thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for suchinteractive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and anotice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program underthese conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but doesnot normally print such an announcement, your work based on the Program is not required to print an announcement.)Company Confidential
Appendix FOpen Software AnnouncementsSTB-2101H User’s Guide268These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program,and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply tothose sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which isa work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other lic-ensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this sec-tion to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control thedistribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based onthe Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does notbring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under theterms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms ofSections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost ofphysically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributedunder the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with theinformation you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommer-cial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsec-tion b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executablework, complete source code means all the source code for all modules it contains, plus any associated interface definition files,plus thescripts used to control compilation and installation of the executable. However, as a special exception, the source code distributedneed not include anything that is normally distributed (in either source or binary form) with the major components (compiler, ker-nel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. Ifdistribution of executable or object code is made by offering access to copy from a designated place, then offering equivalentaccess to copy the source code from the same place counts as distribution of the source code, even though third parties are notcompelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attemptotherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under thisLicense. However, parties who have received copies, or rights, from you under this License will not have their licenses terminatedso long as such parties remain in full compliance.5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to mod-ify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. There-fore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this Licenseto do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license fromthe original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any fur-ther restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by thirdparties to this License.7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patentissues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of thisLicense, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously yourobligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program atall. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copiesdirectly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely fromdistribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, thebalance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the pur-pose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims;this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by pub-lic license practices. Many people have made generous contributions to the wide range of software distributed through that systemCompany Confidential
 Appendix FOpen Software AnnouncementsSTB-2101H User’s Guide 269in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute soft-ware through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what isbelieved to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, theoriginal copyright holder who places the Program under this License may add an explicit geographical distribution limitationexcluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this Licenseincorporates the limitation as if written in the body of this License.9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Suchnew versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Eachversion is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and"any later version", you have the option of following the terms and conditions either of that version or of any later version pub-lished by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose anyversion ever published by the Free Software Foundation.10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write tothe author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free SoftwareFoundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status ofall derivatives of our free software and of promoting the sharing and reuse of software generally.NO WARRANTY11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TOTHE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPY-RIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANYKIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OFMERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY ANDPERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUMETHE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHTHOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTEDABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSE-QUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOTLIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU ORTHIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCHHOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

It also countsas the successor of the GNU Library Public License, version 2, hence the version number 2.1.PreambleThe licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Pub-Company Confidential
Appendix FOpen Software AnnouncementsSTB-2101H User’s Guide270lic Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all itsusers.This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--ofthe Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefullyabout whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on theexplanations below.When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to makesure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receivesource code or can getit if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that youcan do these things.To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrenderthese rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it.For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that wegave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you mustprovide complete object files to the recipients, so that they can relink them with the library after making changes to the library andrecompiling it. And you must show them these terms so they know their rights.We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives youlegal permission to copy, distribute and/or modify the library.To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modi-fied by someone else and passed on, the recipients should know that what they have is not the original version, so that the originalauthor's reputation will not be affected by problems that might be introduced by others.Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannoteffectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that anypatent license obtained for a version of the library must be consistent with the full freedom of use specified in this license.Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNULesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General PublicLicense. We use this license for certain libraries in order to permit linking those libraries into non-free programs.When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speak-ing a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking onlyif the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking othercode with the library.We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary Gen-eral Public License. It also provides other free software developers Less of an advantage over competing non-free programs.These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser licenseprovides advantages in certain special circumstances.For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that itbecomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that afree library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to freesoftware only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free pro-grams enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Libraryin non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linuxoperating system.Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program thatis linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library.The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference betweena "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas thelatter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODI-Company Confidential
 Appendix FOpen Software AnnouncementsSTB-2101H User’s Guide 271FICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyrightholder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called"this License").Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application pro-grams (which use some of those functions and data) to form executables. The "Library", below, refers to any such software libraryor work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivativework under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modificationsand/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term"modification".)"Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source codemeans all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to controlcompilation and installation of the library. Activities other than copying, distribution and modification are not covered by thisLicense; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a pro-gram is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writ-ing it). Whether that is true depends on what the Library does and what the program that uses the Library does.1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, providedthat you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keepintact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along withthe Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protectionin exchange for a fee.2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy anddistribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a)The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating thatyou changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all thirdparties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be suppliedby an application program that uses the facility, other than as an argument passed when the facility is invoked, then you mustmake a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates,and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has apurpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-sup-plied function or table used by this function must be optional: if the application does not supply it, the square root function muststill compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are notderived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, andits terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections aspart of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whosepermissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wroteit. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent isto exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggrega-tion of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage ordistribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of theLibrary. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General PublicLicense, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License hasappeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this changeis made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent cop-ies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into aprogram that is not a library.4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable formunder the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readableCompany Confidential
Appendix FOpen Software AnnouncementsSTB-2101H User’s Guide272source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for softwareinterchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalentaccess to copy the source code from the same place satisfies the requirement to distribute the source code, even though third par-ties are notcompelled to copy the source along with the object code.5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiledor linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, andtherefore falls outside the scope of this License.However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (becauseit contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License.Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header filethat is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not.Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. Thethreshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structurelayouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file isunrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of theLibrary will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code forthe work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they arelinked directly with the Library itself.6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to producea work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permitmodification of the work for the customer's own use and reverse engineering for debugging such modifications. You must giveprominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by thisLicense. You must supply a copy of this License. If the work during execution displays copyright notices, you must include thecopyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you mustdo one of these things: a) Accompany the work with the complete correspondingmachine-readable source code for the Library including whatever changes were used in the work (which must be distributed underSections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work thatuses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modifiedexecutable containing the modified Library. (It is understood that the user who changes the contents of definitions files in theLibrary will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared librarymechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time acopy of the library already present on the user's computer system, rather than copying library functions into the executable, and(2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least threeyears, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing thisdistribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access tocopy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials orthat you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must includeany data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to bedistributed need not include anything that is normally distributed (in either source or binary form) with the major components(compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies theexecutable.It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accom-pany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable thatyou distribute.7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other libraryfacilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the workbased on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a)Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities.Company Confidential
 Appendix FOpen Software AnnouncementsSTB-2101H User’s Guide 273This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact thatpart of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Anyattempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate yourrights under this License. However, parties who have received copies, or rights, from you under this License will not have theirlicenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to mod-ify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. There-fore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License todo so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it.10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license fromthe original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not imposeany further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing complianceby third parties with this License.11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patentissues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of thisLicense, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously yourobligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all.For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directlyor indirectly through you, then the only way you could satisfy both it and this License would be torefrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particularcircumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circum-stances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest valid-ity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which isimplemented by public license practices. Many people have made generous contributions to the wide range of software distrib-uted through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she iswilling to distribute software through any other system and a licensee cannot impose that choice. This section is intended to makethoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, theoriginal copyright holder who places the Library under this License may add an explicit geographical distribution limitationexcluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this Licenseincorporates the limitation as if written in the body of this License.13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time totime. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or con-cerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License whichapplies to it and "any later version", you have the option of following the terms and conditions either of that version or of any laterversion published by the Free Software Foundation. If the Library does not specify a license version number, you may choose anyversion ever published by the Free Software Foundation.14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible withthese, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to theFree Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving thefree status of all derivatives of our free software and of promoting the sharingand reuse of software generally. NO WARRANTY15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TOTHE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPY-RIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANYKIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OFMERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY ANDPERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THECompany Confidential
Appendix FOpen Software AnnouncementsSTB-2101H User’s Guide274COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHTHOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTEDABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSE-QUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOTLIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU ORTHIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCHHOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCHDAMAGES.END OF TERMS AND CONDITIONS.This Product includes gcc-3.4.6 software under GPL 3.0 licenseGNU GENERAL PUBLIC LICENSEVersion 3, 29 June 2007Copyright © 2007 Free Software Foundation, Inc. <http://fsf.org/>Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.PreambleThe GNU General Public License is a free, copyleft license for software and other kinds of works.The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a pro-gram--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your pro-grams, too.When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore,you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others.For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the samefreedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them theseterms so they know their rights.Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you thisLicense giving you legal permission to copy, distribute and/or modify it.For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For bothusers' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attrib-uted erroneously to authors of previous versions.Some devices are designed to deny users access to install or run modified versions of the software inside them, although the man-ufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The sys-tematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problemsarise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, asneeded to protect the freedom of users.Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development anduse of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the pro-gram non-free.The precise terms and conditions for copying, distribution and modification follow.TERMS AND CONDITIONS0. Definitions.“This License” refers to version 3 of the GNU General Public License.“Copyright” also means copyright-like laws that apply to other kinds of works, such as semiconductor masks.“The Program” refers to any copyrightable work licensed under this License. Each licensee is addressed as “you”. “Licensees” and “recipients” may be individuals or organizations.To “modify” a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than themaking of an exact copy. The resulting work is called a “modified version” of the earlier work or a work “based on” the earlierwork.A “covered work” means either the unmodified Program or a work based on the Program.To “propagate” a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includescopying, distribution (with or without modification), making available to the public, and in some countries other activities as well.To “convey” a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying.An interactive user interface displays “Appropriate Legal Notices” to the extent that it includes a convenient and prominently vis-Company Confidential
 Appendix FOpen Software AnnouncementsSTB-2101H User’s Guide 275ible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of thisLicense. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this crite-rion.1. Source Code.The “source code” for a work means the preferred form of the work for making modifications to it. “Object code” means any non-source form of a work.A “Standard Interface” means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that lan-guage.The “System Libraries” of an executable work include anything, other than the work as a whole, that (a) is included in the normalform of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A “Major Component”, in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an objectcode interpreter used to run it.The “Corresponding Source” for a work in object code form means all the source code needed to generate, install, and (for an exe-cutable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified inperforming those activities but which are not part of the work. For example, Corresponding Source includes interface definitionfiles associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms thatthe work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work.The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Correspond-ing Source.The Corresponding Source for a work in source code form is that same work.2. Basic Permissions.All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This Licenseacknowledges your rights of fair use or other equivalent, as provided by copyright law.You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in convey-ing all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copy-righted material outside their relationship with you.Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; sec-tion 10 makes it unnecessary.3. Protecting Users' Legal Rights From Anti-Circumvention Law.No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations underarticle 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention ofsuch measures.When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures.4. Conveying Verbatim Copies.You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; andgive all recipients a copy of this License along with the Program.You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.5. Conveying Modified Source Versions.You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions:a) The work must carry prominent notices stating that you modified it, and giving a relevant date. b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to “keep intact all notices”. c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so.A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the cov-ered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an “aggregate” if the compilation and its resulting copyright are not used to limit the access or legal rights of the Company Confidential
Appendix FOpen Software AnnouncementsSTB-2101H User’s Guide276compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate.6. Conveying Non-Source Forms.You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways:a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for soft-ware interchange. b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corre-sponding Source for all the software in the product that is covered by this License, on a durable physical medium cus-tomarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. c) Convey individual copies of the object code with a copy of the written offer to provide the Correspond-ing Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that sup-ports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsec-tion 6d.A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work.A “User Product” is either (1) a “consumer product”, which means any tangible personal property which is normally used for per-sonal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a partic-ular user, “normally used” refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumerproduct regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses representthe only significant mode of use of the product.“Installation Information” for a User Product means any methods, procedures, authorization keys, or other information required toinstall and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case preventedor interfered with solely because modification has been made.If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveyingoccurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpe-tuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this sec-tion must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third partyretains the ability to install modified object code on the User Product (for example, the work has been installed in ROM).The requirement to provide Installation Information does not include a requirement to continue to provide support service, war-ranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been mod-ified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network.Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special pass-word or key for unpacking, reading or copying.7. Additional Terms.“Additional permissions” are terms that supplement the terms of this License by making exceptions from one or more of its con-ditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in thisLicense, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, thatpart may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions.When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.)You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission.Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copy-right holders of that material) supplement the terms of this License with terms:a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such Company Confidential
 Appendix FOpen Software AnnouncementsSTB-2101H User’s Guide 277material be marked in reasonable ways as different from the original version; or d) Limiting the use for publicity purposes of names of licensors or authors of the material; or e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these con-tractual assumptions directly impose on those licensors and authors.All other non-permissive additional terms are considered “further restrictions” within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveyingunder this License, you may add to a covered work material governed by the terms of that license document, provided that the fur-ther restriction does not survive such relicensing or conveying.If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the addi-tional terms that apply to those files, or a notice indicating where to find the applicable terms.Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way.8. Termination.You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11).However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provision-ally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyrightholder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the vio-lation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) fromthat copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights fromyou under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10.9. Acceptance Not Required for Having Copies.You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a coveredwork occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance.However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptanceof this License to do so.10. Automatic Licensing of Downstream Recipients.Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modifyand propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License.An “entity transaction” is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to thattransaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessorin interest, if the predecessor has it or can get it with reasonable efforts.You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiatelitigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, sell-ing, offering for sale, or importing the Program or any portion of it.11. Patents.A “contributor” is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's “contributor version”.A contributor's “essential patent claims” are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor ver-sion. For purposes of this definition, “control” includes the right to grant patent sublicenses in a manner consistent with therequirements of this License.Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version.In the following three paragraphs, a “patent license” is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To “grant”such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party.If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readilyaccessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of thisLicense, to extend the patent license to downstream recipients. “Knowingly relying” means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country,would infringe one or more identifiable patents in that country that you have reason to believe are valid.If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, Company Confidential
Appendix FOpen Software AnnouncementsSTB-2101H User’s Guide278modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipientsof the covered work and works based on it.A patent license is “discriminatory” if it does not include within the scope of its coverage, prohibits the exercise of, or is condi-tioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a cov-ered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection withcopies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with spe-cific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license wasgranted, prior to 28 March 2007.Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law.12. No Surrender of Others' Freedom.If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License,they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneouslyyour obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. Forexample, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Pro-gram, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program.13. Use with the GNU Affero General Public License.Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of theGNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such.14. Revised Versions of this License.The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU Gen-eral Public License “or any later version” applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation.If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program.Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version.15. Disclaimer of Warranty.THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PUR-POSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR COR-RECTION.16. Limitation of Liability.IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.17. Interpretation of Sections 15 and 16.If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection withthe Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee.END OF TERMS AND CONDITIONSHow to Apply These Terms to Your New ProgramsIf you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectivelystate the exclusion of warranty; and each file should have at least the “copyright” line and a pointer to where the full notice is found.    <one line to give the program's name and a brief idea of what it does.>    Copyright (C) <year>  <name of author>    This program is free software: you can redistribute it and/or modify    it under the terms of the GNU General Public License as published by    the Free Software Foundation, either version 3 of the License, or    (at your option) any later version.Company Confidential
