How to use the CLI
CLI levels
CLI consists of several levels. You can move from one level to other by step by step.(See picture 34 and table 10 for detailed description). To execute the command, press enter after typing command.
Instead of writing complete command, you may use shortenings such as quit = q and confi g terminal = c t. To separate commands having same initial letter(s), the shortening must be more specifi c by adding more command’s letters, e.g. end = en and exit = ex.
The CLI levels are:
- Disable (Basic level)
- Enable (Settings viewing level)
- Confi g (Administer level)
- Confi g-if (Data settings editing level)
- Confi g-if (Ethernet port settings editing level)
- Confi g-sap (SAP settings editing level)
- Confi g-ts (Video/audio settings editing level)
-
Confi g-fi lter (Unicast video settings editing level, only in BBD)
- Confi g-line (Terminal view settings editing level)
Note! All letters must be typed as lowercase.

Glossary
Bandwidth
The width of a communication channel, measured as frequency (hertz) or bits per second (bps).
Baudrate
The speed of information being transmitted across a serial interface, expressed in units of bits per second (bps). For example, a baud rate of 9600 refers to bits being transmitted (or received) from one piece of equipment to another at a rate of 9600 bps. Thus, a seven bit ASCII character plus parity bit plus one stop bit (total nine bits) would be transmitted in 9/9600 sec. = 0.94 ms or about 1000 characters/sec. When communicating via a serial interface, the baud rate settings for two pieces of equipment must match.
Bit
A binary digit - either 0 or 1. Abbreviated b for bit or bits.
Bit Rate (BR)
The rate of data throughput on a medium (measured in bps or Hz, whichever is more appropriate to the context).
CBR (Constant Bit Rate)
A term that describes how video or audio is encoded. Constant bit rate means that the bit rate doesn’t vary during the video or audio at all, but is same through the clip.
Ethernet
Specifi ed in a standard, IEEE 802.3. 10BASE-T Ethernet systems provide transmission speeds up to 10 Mbps. Fast Ethernet or 100BASE-T provides transmission speeds up to 100 megabits per second and is typically used for LAN backbone systems, supporting workstations with 10BASE-T cards. Gigabit Ethernet provides an even higher level of backbone support at 1000 megabits per second (1 gigabit or 1 billion bits per second).
Fast Ethernet
Also referred to as 100Base-Tand 100Base-X. Uses CSMA/CD access method at 100 Mbps; IEEE 802.3u; MII replaces AUI. Can use full duplex (200 Mbps). 100m limit for UTP implementation. Numerous wiring options: 100Base-TX, 100Base-T4, 100Base-FX; 4b5b/MLT-3 encoding. A fi rewall exhibits the following properties: all traffi c between networks must fl ow through it, only autho­rized traffi c is allowed to pass, and the fi rewall should be immune to compromise.
Frame Rate
An attribute (relevant just for video mostly) which determines the video fl uency. The TV transmission in Europe (PAL standard) has a frame rate of of 25 fps (or more exactly 50 fi elds per second). The frame rate in US (NTSC standard) is 30 fps.
CIF - Common Intermediate Format
A commonly used television standard for measuring resolution. QCIF equals 176 x 120 pixels for NTSC and 176 x 144 pixels for PAL. CIF equals 352 x 240 pixels for NTSC and 352 x 288 pixels for PAL. 2CIF equals 704 x 240 pixels for NTSC and 704 x 288 pixels for PAL. 4CIF equals 704 x 480 pixels for NTSC and 704 x 576 pixels for PAL.
Client/Server
A model of computing in which a desktop client application has the necessary intelligence to access servers or hosts on the network to request informa­tion or perform queries about available resources.
Command Line Interface (CLI)
A text-based user interface. Allows the user to interact with the operating system by entering commands and optional arguments.
DHCP (Dynamic Host Confi guration Protocol)
Internet standard (RFC 1541) protocol for distributing confi guration information to network and allows a computer to obtain its own IP address automatically rather than having it entered manually.
Full Duplex
The ability to transmit and receive signals simultaneously.
Gateway
Gateways are points of entrance to and exit from a communications network. Viewed as a physical entity, a gateway is that node that translates between two otherwise incompatible networks or network segments.
Gigabit Ethernet
Informal name for emerging standard (IEEE 802.3z) CSMA/CD technology designed to provide 1Gbps network connectivity. Based on existing and evolving
802.3 standards, Gigabit Ethernet is expected to incorporate both half and full-duplex operation, link­level fl ow control, VLAN support, and systems management. Support for one repeater per collision domain, backward compatibility with 10Base-T and 100Base-TX. New technologies introduced include packet bursting and carrier extension. For half-duplex devices carrier time and slot time are extended to 4096 bit times. Minimum packet length is same as existing Ethernet (64 B).
Glossary 33
Page 36
Half Duplex
The ability to transmit and receive signals in both directions, but only in one direction at a time
Host
Any device on the network that implements communi­cation above the Data Link Layer.
Hostname
A synonym for IP domain name, which typically takes the form host.institution.domain
Hub
A physical layer device, generally used to serve at the center of a star-topology network. Hubs accept host, internetworking, and network management modules; and provide re-timing/repeater, bridging, and/or network management functionality. Ethernet 2 and IEEE 802.3 terminology, a hub is an Ethernet multi-port repeater, which sometimes referred to as a concentrator.
ICMP (Internet Control Message Protocol)
The Internet standard protocol (RFC 792) used to handle errors and control messages at the IP layer. ICMP is actually part of the IP protocol.
IGMP (Internet Group Multicast Protocol)
The Internet standard (RFC 1112) extensions to IP that support IP datagram multicasting to a “host group.” Membership in a host group is dynamic and there are no topological restrictions to participating in a host group. Hosts groups may be either perma­nent or transient. Host groups are identifi ed by Class D IP addresses. There are three levels of confor­mance: 0: no support; 1: support for sending but not receiving; 2: full support.
IP (Internet Protocol)
Internet Protocol; the most important protocol of the Internet suite. IP allows information to traverse multiple networks worldwide. The network layer protocol (RFCs 760, 791) for the Internet protocol suite.
Latency
Measure of time, within a forwarding device, between receipt of the fi rst bit of a packet on input and the generation of the fi rst bit of the same packet forwarded on output.
Local Area Network (LAN)
A local area network is generally a private network. It is under the control of the owner and used by a set of related individuals and/or workgroups, typically within a single building or over a group of neighbor­ing buildings. LANs are a group of computers and associated devices that share a common communi­cations line and typically share the resources of a single processor or server within a small geographic area (for example, within an offi ce building). Usually, the server has applications and data storage that are shared in common by multiple computer users. A local area network may serve as few as two or three users (for example, in a home network) or many as thousands of users (for example, in an FDDI network).
MAC (Media Access Control)
The protocol level that describes network management frames sent on the 802.5 token ring. Most MAC frames are handled transparently by the network adapter.
MAC Address
The unique physical (data link layer) address of an individual network interface. The standard specifi es both 16- and 48-bit addresses. The 802.1 standards committee has defi ned a canonical format for writing and transmitting a MAC address. It is expressed as six octets separated by hyphens, each octet repre­sented as twohexadecimal digits, least-signifi cant bit fi rst (littleendian). (As a matter of custom, non­canonical, most-signifi cant bit fi rst representation is given using colons as the octet separator). For example, 08-00-20-85-e6-8d is a typical canoni­cal MAC address. Within the MAC address are a number of fi elds of interest. The most signifi cant (fi rst) bit, known as the I/G bit (for Individual or Group) is 0 if the address represents an individual station; it is 1 if the address is a multicast (group or broadcast) address. The second bit, known as the U/L (for Universal or Local) bit is 0 if the address is globally administered and registered with the IEEE; it is 1 if it is a locally administered address.
MAC sublayer
Media Access Control sublayer. As defi ned by the IEEE, the lower portion of the OSI reference model data link layer. The MAC sublayer is concerned with media access issues, such as whether token pass­ing or contention will be used.

Page 37
Metropolitan Area Network (MAN)
A network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network (LAN) but smaller than the area covered by a wide area network (WAN). The term is applied to the interconnection of networks in a city into a single larger network (which may then also offer effi cient connection to a wide area network). It is also used to mean the interconnection of several local area networks by bridging them with backbone lines. The latter usage is also sometimes referred to as a campus network.
MIB (Management Information Base)
A collection of objects (database) that can be accessed via a network management protocol. See SNMP and RFC 1066.
MIB-II (Management Information Base, Version 2)
The revised object defi nitions for Internet standard network management. Objects are defi ned using a subset of the Abstract Syntax Notation One (ASN.1). See SNMP and RFC 1213.
MTU (Maximum Transmission Device)
The largest possible device of data that can be transmitted between a source and a destination. Note that a distinction must be made between the MTU for a physical medium (segment), a path, and for protocols. For example, Ethernet has an MTU of 1500 bytes, while FDDI has an MTU of 4470 bytes; ATM uses an MTU of 9180 bytes. AppleTalk has an MTU of 600 bytes, while IP has an MTU limit of 65 535 bytes (less the header). The MTU between two endstations is always the minimum of the MTUs of all the media (segments) separating the endstations. See RFC 1191 for a discussion of determining the MTU of an internetwork between two endpoints.
Multicast
Communication between a single sender and multiple receivers on a network. Streaming content can be sent multicast from one server to many users. Compare with unicast.
Multicast Address
An address that refers to multiple network devices. Synonymous with group address.
MPEG (Moving Pictures Experts Group)
An ISO (International Standards Organization) group that sets standards for compressing and storing video, audio, and animation in digital form.
MPEG-1
Provides a video resolution of 352 by 240 at 30 frames per second (fps). This was designed to work at 1.2 Mbps. Is meant for medium-bandwidth usage.
MPEG-2
Offers resolutions of 720 x 480 and 1280 x 720 at 60 fps, with data rates of between 1.2 and 15 Mbps, with full CD-quality audio. Is meant for high-band­width/broadband usage.This works for all the major TV standards, including NTSC and even HDTV.
MPEG-4
Designed specially for low-bandwidth (less than
1.5 Mbps bitrate) video/audio encoding purposes. Delivers video at comparable quality to MPEG1 at a much lower bit rate. Also supports a wide variety of elements that can be transmitted separately and combined to form the video frame, such as a talking head in one stream and the background in another. Allows manipulation of objects within the video stream (addition, subtraction, object manipulation, etc.).
Multimode Fiber (MMF)
Optical fi ber cable with a relatively wide core (62.5 µm or 50 µm) that allows multiple rays of light to follow different paths through the core.Termination is easier and cheaper, driven by optical diodes, good for short distances typically up to 2 km, more forgiving of termination errors.
Netmask
A bit mask used to select bits from an Internet address for subnet addressing. The mask is 32 bits long and selects the network portion of the Internet address and one or more bits of the local portion. This is also sometimes referred to as the address mask or subnet mask.
Network
A group of stations (computers, telephones, or other devices) connected by communications facilities for exchanging information. Connection can be perma­nent, via cable, or temporary, through telephone or other communications links. The transmission medium can be physical (i.e. fi ber optic cable) or wireless (i.e. satellite).
Network Address
The hostid 0 of an IP address is reserved; an IP address with the hostid zero is used to refer to the network itself.

Network Layer: OSI Layer 3
Provides upper layers with independence from the data transmission and switching technologies used to connect systems; responsible for establishing, maintaining, and terminating connections. Respon­sible for routing, switching, and subnetwork access across the entire OSI environment.
Network Time Protocol (NTP)
An Internet standard protocol (RFC 1305) built on top of UDP/IP, port 123, that assures accurate local timekeeping with reference to international time standards (radio, satellite, atomic clocks) via the Internet. The protocol is capable of synchronizing distributed clocks within milliseconds over long time periods.
NTSC and PAL resolutions
In North America and Japan, the NTSC standard (National Television System Committee) is the predominant analog video standard, while in Europe the PAL standard (Phase Alternation by Line) is used. Both standards originate from the television industry. NTSC has a resolution of 480 horizontal lines, and a frame rate of 30 fps. PAL has a higher resolution with 576 horizontal lines, but a lower frame rate of 25 fps. The total amount of information per second is the same in both standards.
Packet
Generic term used to describe a contiguous device of data with attached control information. Does not distinguish between frames and cells.
Parity
A data-checking technique, which uses an extra bit. If you send one extra-bit for each data bits to make sure your data got there intact, add and send one more bit - a parity bit. Bit parity could be odd or even. If it is even, you assign 0 to the parity bit in case when the sum of data bits is a even number and 1 if it is odd. It is odd, if the logics is reversed. After the data bits has arrived, the system will sum data bits and check if it matches the eve-or-oddness predicted by the parity byte.
PAT (Program Association Table)
Data appearing in packets having PID code of zero that the MPEG decoder uses to determine which programs exist in a Transport Stream. PAT points to PMT, which, in turn, points to the video, audio, and data content of each program.
PSI (Program Specifi c Information)
Information that keeps track of the different pro­grams in an MPEG transport stream and in the elementary streams in each program. PSI includes PAT, PMT, NIT, CAT, ECM, an d EMM.
PMT (Program Map Tables)
The tables in PAT that point to video, audio, and data content of a transport stream.
PCR (Program Clock Reference)
The sample of the encoder clock count that is sent in the program header to synchronize the decoder clock.
PCRI (Interpolated Program Clock Reference)
A PCR estimated from a previous PCR and used to measure jitter.
PID (Program Identifi er)
A 13- bit code in the transport packet header. PID 0 indicates that the packet contains a PAT PID. PID 1 indicates a packet that contains CAT. The PID 8191 (all 1s) indicates null (stuffi ng) packets. All packets belonging to the same elemen­tary stream have the same PID.
Ping (Packet InterNet Groper)
Ping is a program that “bounces” a request off of another computer over a network to see if the remote computer is still responding. If the ping comes back, the remote computer is still alive.
Point-to-point
A virtual circuit, usually circuit switched, established between exactly two end points. End point technol­ogy is typically some bit serial interface, although a wide range of line capacity could be used.
Protocol
A formal description of messages to be exchanged and rules to be followed for two or more systems to exchange information.
QoS (Quality of Service)
Interactive video conferencing requires a high QoS. QOS is important as it determines the quality of your video call. Low quality of service results in latency and a jerky picture with poor and inconsis­tent audio quality.
Ring
A network topology in which all nodes are connected in a closed loop. Transmission is permitted by passing a token around the ring; a node copies out messages addressed to it and copies in messages addressed to others. Message receipt verifi cation can also be performed with the token.
RMON (Remote Network Monitoring Management Information Base - RFC 1271)
An agent (embedded or stand-alone) that can continuously collect performance, fault, and confi gu­ration statistics, perform diagnostic operations, operate autonomously, generate management traps, and return collected data to a management station.

Router
On the Internet, a router is a device or, in some cases, software in a computer, that determines the next network point to which a packet should be forwarded toward its destination. The router is connected to at least two networks and decides which way to send each information packet based on its current understanding of the state of the networks it is connected to. A router is located at any gateway (where one network meets another), including each Internet point-of-presence. A router is often included as part of a network switch.
RTP (Real Time Protocol)
A wrapper around a real time stream of video or audio data. It is delivered usually via UDP. It is commonly used to transmit surveillance video. There are a great many formats supported within RTP framing. RFC 1889 describes the protocol.
SAP (Session Announcement Protocol)
An announcement protocol that is used to assist the advertisement of multicast multimedia conferences and other multicast sessions, and to communicate the relevant session setup information to prospective participants.
Serial Communication Interfaces
• RS232 (single ended voltage signal)
• RS422 (differential voltage signal, single drop)
• RS485 (differential voltage signal, multidrop) duplex (4 wire), half-duplex (2 wire)
RS232 is the most common serial line interface. All personal computers have at least one RS232 serial port. RS232 is an unbalanced or single ended peer to peer Line Interface Standard. RS232 is ideal for connecting short distances less than 50 ft/15 meters. In general RS232 is limited to 100 kbps, but new technologies allow for baud rates over 1 Mbps along short distances of cable.
RS422 is used in situations where long distances are required. RS422 can drive up to 4000 ft/1220 meters at 100 kbps. Or short distance’s over 1 Mbpps RS422 allows for one driver and up to ten receivers to be on a multi-dropped network or bus. RS422 is a differential or balanced Line Interface Standard.
RS485 is used in situations similar to where RS422 is used. RS485 has the added advantage of allowing up to thirty two (32) multi-dropped receivers or transmitters on a multi-dropped network or bus. Furthermore RS485 also permits a wire saving (1/2) duplex mode.
Scalability
A characteristic of MPEG2 that provides for multiple quality levels by providing layers of video data. Multiple layers of data allow a complex decoder to produce a better picture by using more layers of data, while a more simple decoder can still produce a picture using only the fi rst layer of data.
Server
A networked computer that contains public resourc­es or services that can be accessed using software applications called “clients.”
Single-mode Fiber (SMF)
Optical fi ber cable with a narrow core (8 to 9 µm) that allows light to travel along, only one path, driven by optical lasers. Used for long-distance signal transmission, typically up to 40 km.
Spanning Tree Protocol (STP)
A standard bridge protocol (IEEE 802.1d). This protocol allows bridges to dynamically discover a subset of the LAN topology that is loop-free and provides connectivity to all LAN segments.
Stop bit
In serial communications, where each bit of the message is transmitted in sequence, stop bits are extra “1” bits which follow the data and any parity bit. They mark the end of a unit of transmission (nor­mally a byte or character). For example, characters on an EIA-232 serial line may have one or two stop bits added. A serial connection may be described as, for example, “8N1” which means eight data bits, no parity and one stop bit.
Switch
An internetworking device (multiport bridge) that intelligently segments networks to increase overall bandwidth, isolate traffi c and provides an interface to high-speed networks. The switch selects a path or circuit for sending a device of data to its next destination. A switch may also include some func­tions of the router, a device or program that can determine the route and specifi cally what adjacent network point the data should be sent to. In general, a switch is a simpler and faster mechanism than a router, which requires knowledge about the network and how to determine the route.

TCP/IP (Transmission Control Protocol/ Internet Protocol)
The basic communication language or protocol of the Internet. It can also be used as a communica­tions protocol in a private network (either an intranet or an extranet). When you are set up with direct access to the Internet, your computer is provided with a copy of the TCP/IP program just as every other computer that you may send messages to or get information from also has a copy of TCP/IP.
Telnet ( “Terminal Emulation”)
Protocol that enables you to log in to other computer systems on the Internet.
Terminal
Computer terminal; a device that is able to communi­cate (usually asynchronously) with a host computer.
Unicast
Communication between a single sender and a single receiver on a network. Streaming content can be sent unicast from one server to one user. Compare with Multicast.
VBR (Variable Bit Rate)
A term that describes how video or audio is encoded. Variable bit rate provides a specifi ed throughput capacity but data is not sent evenly.
Videoconferencing
Communication across long distances with video and audio contact that may also include graphics and data exchange. Digital video transmission systems typically consist of camera, codec (Encod­er-Decoder), network access equipment, network, and audio system, e.g. EASI™ BLUEbox devices.
Time to Live (TTL)
A value in an Internet Protocol (IP) packet that tells a network router whether or not the packet has been in the network too long and should be discarded.
Transport Stream
A multiplex of several program streams that are carried in packets. Demultiplexing is achieved by different packet IDs (PIDs). See PSI, PAT, PMT, and PCR.
UDP (User Datagram Protocol)
A connectionless transport layer protocol in the TCP/IP protocol stack (RFC 768). UDP is a simple protocol that exchanges datagrams without acknowledgments or guaranteed delivery, requiring that error processing and retransmission be handled by other protocols.
VLAN (Virtual LAN)
Network confi guration, emulating a broadcast domain, where stations communicate using LAN protocols as if they were on the same LAN, but where they are actually on multiple segments connected through layers 1, 2, and/or 3.
Wide Area Network (WAN)
A geographically dispersed telecommunications network. The term distinguishes a broader telecom­munication structure from a local area network (LAN). A wide area network connects local area networks to one another, generally using public infrastructure or services. The connections are made using the shared public infrastructure, public infrastructure leased for private use, and sometimes, private infrastructure (e.g., fi ber) with public services.
