1.6 GROUND TERMINAL
The marked lug or terminal should be connected to the building protec­tive earth bus. The function of protective earth does not serve the pur­pose of providing protection against electrical shock, but instead enhances surge suppression on the lines for installations where suitable bonding facilities exist. The connector type is M3 machine screw.
2. APPLICATIONS OVERVIEW
The Black Box LB52xA-KIT sim plifie s and provid es cos t eff ectiv e network ex tension by utilizing pre-existing twisted pair infrastructure. This enables service providers to offer broadband or data backhaul services to businesses, governments and various institu­tions over existing last-mile, copper infrastructure. Today, more than ever, operator s are finding the bu siness case for levera gin g th eir e xi sti ng c op per n etw o rks to be highly attractive from an ROI and initial investment perspective over fiber roll-outs.
2.1 TYPICAL APPLICATION
The Black Box Exte nders are the perfect fit f or s im ple , c ost -effective high speed Ether­net Extension. They allow customers to take advantage of the existing copper infra­structure to connect remote LANs across distances and at speeds previously unthought-of. The auto-rate feature ensures the highest speed is achieved on each connection, and the plug and play operation ensures they are up and running in sec onds. Add in the 4 x auto-sensing full/half duplex 10/100Base-TX Ethernet ports with the integrated crossover switch to make setup even easier. The value of these Ether net Extenders can’t be beat!
• Auto-Rate Feature—The advanced auto-rate algorithm automatically deter­mines the best possible rate for each connection and sets up each extender without any need for user interface.
• Plug and Play—Just unpack the extenders, plug them into each end of the extension, power them up, and they are up and running. It doesn’t get any eas ier!
• High Speed/Long Reach—These Ethernet Extenders provide the best combi- nation of speed and distance seen anywhere in the industry!

4.2.2 DHCP server
Dynamic Host Configuration Protocol (DHCP) is a communication protocol that allows network administrators to manage and automate the assignment of Internet Protocol (IP) addresses in an organization's network. Each machine that can connect to the Internet requires a unique IP address. When an organization sets up the users with a connection to the Internet, an IP address must be assigned to each machine.
Without DHCP, the IP address must be entered manually at each computer. If comput­ers move t o another lo cation in another part of the network, a new IP address must be entered. DHCP lets a network administrator supervise and distribute IP addresses from a central point and automatically sends a new IP address when a computer is plugged into a different place in the network. The embedded DHCP server assigns network configuration information to 253 users (max) accessing the Internet in the same time. For e xa mple, if the LAN IP addre ss is 1 92. 168 .0.1 , th e IP range of the LAN is 192.168.0.2 to 192.168.0.254.
To set up the DHCP Server for the LB52xA-KIT:
1. Click on Basic from the main menu, set up the Operation Mode and Manage- ment port, then click Next to reac h the DHCP Server page.
2. The DHCP server assigns the IP fro m the Start IP Address to t he End IP Address. The legal IP address range is from 0 to 255, but 0 is reserved as the network name and 255 is reserved for broadcast. This implies that the legal IP address range is from 1 to 254. That means you cannot assign an IP greater than 254 or less than 1.
3. A Lease Time of 72 hours indicates that the DHCP server will reassign IP infor­mation every 72 hours, whi ch is the defaul t value for the LB52xA-KIT. You can set up the Lease Time for a range from 1 to 720 hours according to your application.
4. If you assign a fixed IP address to a de vice whi le using DHCP, you must enter the device's MAC address in the Table of Fixed DHCP Host Entries.

VLAN page
VLAN (Virtual Local Area Network) allows a physical network to be partitioned into multiple logical networks. Devices on a logical network belong to one group. A device can belong to mor e than one group. Wi th VLAN, a dev ice ca nnot dire ctly t alk to or hear from devices that are not in the same group.
With MTU (Multi-Tenant Unit) applications, VLAN is vital in providing isolation and security among the subscribers. When properly configured, VLAN prevents one sub
-
scriber from accessing the network resources of another on the same LAN. VLAN also increases network performance by limiting broadcasts to a smaller and
more manageable logical broadcast domain. In traditional switched environments, all broadcast packets go to each individual port. With VLAN, all broadcasts are confined to a specific broadcast domain.
You can select from two types of VLAN: 802.1Q Tag-Based VLAN and Port-Based VLAN. The VLAN Setup screen changes depending on whether you choose 802.1Q Tag-Based VLAN type or Port Based VLAN type. The IEEE 802.1Q define s the opera
­tion of VLAN bridges that permit the definition, operation, and administration of VLAN topologies within a bridged LAN infrastructure.

• Link Type: Select from Access or Trunk. Access m eans the p ort can receiv e or send untagged packets. Trunk means that the port can receive or send tagged packets.
In 802.1q, the VLAN information is written into the Ethernet packet itself. Each packet carries a VLAN ID (Virtual LAN ID) called a tag. This tag allows VLANs to b e config ured across multiple switches.
NOTE: VLAN tags may be stripped by the hardware or the software.
When using 802.1q, four bytes are added to the Ethernet frame, and 12 bits are used for the VLAN ID. Theoretically, there can be up to 4096 VLANs per network.

An Ethernet packet that contains a VLAN ID is called a tagged packet. An Ethernet packet without a VLAN ID is called an untagged packet. Typically, all packets leave untagged, unless tagged by the adapter prior to arriving at the switch port.
Egress and Ingress Rules. Egress rules determine which frames can be transmitted out of a port, based on the Egress List of the associated VLAN. Each VLAN has an Egress List that specifies the ports out of which frames can be forwarded, and speci fies whether the frames will be transmitted as tagged or untagged frames.
Ingress rules are a means of filtering out undesired traffic on a port. When Ingress Fil­tering is enable d, a p ort de term in es if a fra me can be pr oce ss ed bas ed o n whether the port is on the Egress List of the VLAN associate d with the frame.
When an untagged packet arrives at the switch port, the switch will write a VLAN ID into the header of the frame according to the PVID (port VLAN) definition. Typically, most switches today have all ports set to a default PVID of 1. When a tagged frame arrives at a switch port, the tag is respected.
-
A VID defines the member of a port group. A packet can only travel inside a member port when the member port is part of a VID po rt group. D ifferent VID groups are no t visible to one another.

802.1P.
• Priority defines the pri ority level for dif fe r ent cl as ses of traffic. There are 8 possi­ble priority levels, with 0 being the lowest priority level and 7 being the highest level. IEEE 802.1P defines the operation for these 3 user priority bits.
• Canonical Format Indicator (CFI) is always set to zero for Ethernet switches. CFI is used for compatibility reasons between an Ethernet-type network and Token Ring-type network. If a frame recei ved at an Ethe rnet port has a CFI set to 1, then that frame should not be forwarded as it is to an untagged port.
• VLAN ID (VID) is the uni que identi ficati on number o f the VLAN, wh ich is us ed by the standard 802.1Q. It has 12 bits and allows the identification of 4096 (212) VLANs. Of the 4096 possible VIDs, a VID of 0 is used to identify priority frames and the value 4095 (FFF) is reserved, so the maximum possible VLAN configu rations are 4,094.
-
The LB52xA-KIT initially configures one VLAN by default, VID=1. A port such as LAN1–4, line or sni ffi ng can have only one Port VID (P VID), but can ha ve as many VID groups as the LB52xA-KIT has memory in its VLAN table to store them.
Ports in the same VLAN group share the same frame broadcast domain thus increase network performance through reduced broadcast traffic. You can modify VLAN groups at any time by adding, moving or changing ports without any re-cabling.

Configuring 802.1Q VLAN Tagging. Before enabling VLANs fo r the L B52x A-KIT, you must first assign each port to the VLAN group(s) in which it will participate. By default all ports are assigned to VLAN1 as untagged ports. Add a port as a tagged port if you want it to carry traffic for one or more V LANs, and any intermediate ne tw ork devic es or the host at the other end of the connection supports VLANs. Then, assign ports on the other VLAN-aware n etwor k devic es alo ng the pat h th at will carry t his tra ffi c t o the s ame VLAN(s), either manually or dynamically using Generic VLAN Routing Protocol (GVRP). However, if you want a port on this LB52xA-KIT to participate in one or more VLANs, but none of the intermediate network devices nor the host at the other end of the connection supports VLANs, then you should add this port to the VLAN as an untagged port.
NOTE: VLAN-tagged frames can pass through VLAN-aware or VLAN-unaware net­work inter-connection devices, but the VLAN tags should be stripped off before pass­ing it on to any end-node host that does not support VLAN tagging.
• VLAN Classification - When the LB52xA-KIT receives a frame, it classifies the frame in one of two ways. If the frame is untagged, the LB52xA-KIT assigns the frame to an associated VLAN (based on the default VLAN ID of the receiving port). But if the frame is tagged, the LB52xA-KIT uses the tagged VLAN ID to identify the port broadcast domain of the frame.
724-746-5500 | blackbox.com
Page 39
Page 40
• Port Overlapping - You can use port overlapping to allow access to commonly shared network resources among diffe rent VLAN grou p s , such as fil e serv ers or printers.
• Untagged VLANs - Untagged (or static) VLANs are typically used to reduce broadcast traf fic a nd to i ncrease security. A group of network users assign ed to a VLAN form a broadcast d omain that is se parate fro m other VLANs co nfigured on the LB52xA-KIT. Packets are forwarded only between ports that are designated for the same VLAN. Untagged VLANs can be used to manually isolate user groups or subnets.
• Port VID (PVID) - A PVID is a VLAN ID assigned to untagged frames received on the interface. (Default: 1). If an interface is not a member of VLAN 1 and you assign its PVID to this VLAN, th e interfac e will autom atically be added to VLAN 1 as an untagged member. For all other VLANs, an interface must first be config ured as an untagged member before you can assign its PVID to that group.
• Link Type - The Link Type determines the types of frames the port can accept. Access means the port can only receive or send untagged frame types. Trunk means that the port can only receive or send tagged frame types.

Web Configuration
Port-Based VLANs are VLANs where the packet forwarding decision is based on the destination MAC address and its associated port. When using port-based VLAN, the port is assigned to a specific VLAN independent of the user or system attached to the port. This means all users attached to the port should be members in the same VLAN. The network administrator typically performs the VLAN assignment. The port configu­ration is static and cannot be automatically changed to another VLAN without manual reconfiguration.
As with other VLAN approaches, the packets forwarded using this method do not leak into other VLAN domains on the network. After a port has been assigned to a VLAN, the port cannot send to or receive from devices in another VLAN.
4.3.3 Quality of Service (QoS)
Quality of Service (QoS) refers to both a network's ability to deliver data with mini­mum delay, and the networking methods use d to co ntro l the use of bandwid th. Without QoS, all traffic data is equall y like ly to be dr opped whe n the netw ork is conges ted. Thi s can cause a reduction in network performance and mark the network inadequate for time-critical application such as video-on-demand.
Click on QoS under Advanced on the main menu to reach the QoS advanced configu- ration page.
Figure 20.
QoS page
QoS (Quality of Service) is used to decide which devices can get priorities to pass though the LB52xA-KIT once the bandwidth is exhausted or fully saturated.
There are three types of QoS priority modes: Port Based Priority, VLAN Tag Priority, and IP DSCP Priority. Yo u can also disable the QoS function.

Select the ports that the port-based priority rule should be applied. There are six ports to choose from: LAN1, LAN2, LAN3, LAN4, DSL and Sniffing.
The common setting tables are: WRR configuration: Each queue type can setup the queue weight from 1 to 15. WFQ configuration: Each ports and their queue type can set the bandwidth. Scheduling Configuration.The LB52xA-KIT provides three combinations of four
commonly used techniques: Type 1, Type 2 and Type 3. Select a type in the Schedul ing Configuration section, then provide details in the corresponding table.

If you select Type 2 or Type 3, refer to “WFQ Configuration” on page 43. The Queue types are Weight Round Robin (WRR), Weighted Fair Queuing (WFQ),
Best Effort (BE) and Strictly Priority (SP). Refer to the following page for more infor mation on how each Queue Type operates.
• Weight Round Robin (WRR): All received packets will be stored into Queue 1, Queue 2, Queue 3, and Queue 4. Assign a weight value fo r ea ch queue. Then, WRR will re-assemble all packets from the four queues based on the weight assignments.
-
Figure 22.
WRR Example
For exampl e, Figu re 22. shows the weight value of each queue, ranging from 4, 2, 5, and 1. When the LB52xA-KIT starts to process all of the packets in these queues with WRR, a new packet develops based on the weight assignments. Then, the LB522A­KIT sends out the new packet.
• Weighted Fair Queuing (WFQ): WFQ is a generalization of processor sharing, which allows several sessions to share the same link. Refer to “WFQ Configura
­tion” on page 45 to assign the data size of each queue that can be accepted by each port.
724-746-5500 | blackbox.com
Figure 23.
WFQ Example
Page 43
Page 44
• Best Effort (BE): The BE Queue Type is used for data applications that have low priority or the potential to delay. BE does not use traffic priority or weight assignments, therefore BE is not recommended for high priority data, such as video or voice.
Figure 24.
BE Example
• Strictly Priority (SP): The SP Q ueu e Type us es que ues that are based on pri or­ity only. SP transmits the highes t priority queue fi rst, then the ne xt highest p riority queue, and so on. However, if there is always some content in the highe st pri or ity queue, then the other packets in the rest of queues will not be sent until the highest priori ty queue is emp ty. The SP algorit hm is prefe rred when t he receiv ed packets contain some high priority data, such as voice and video.

Configuration Example. As an example, you can set the LB52xA-KIT to use Weighted Round-Robin (WRR) queuing that specifies a relative weight of each queue. WRR uses a pred efined relativ e weight for ea ch que ue that d etermi nes the percen t age of service time to provide each queue before moving on to the next queue. This pre vents the head-of-line blocking that can occur with strict priority queuing.

when in fact they are located on a number of different LAN segments. Because VLAN is based on logical instead of physical connections, it is extremely flexible.
You can setup the Virtual LAN (VLAN) parameters in VLAN command. The LB5 2xA­KIT supports VLAN-to-PVC only for bridge mode operation, i.e., the VLAN spreads over both the CO and CPE sides, where there is no layer 3 routing involved. The unit supports up to 8 active VLANs with shared VLAN learning (SVL) bridge out of 4096 possible VLANs specified in IEEE 802.1Q.
The vlan command menu lists commands for setting up the line port. Move the cursor “ >>” to vlan in the setup menu and press Enter. The following menu displays:

Port-Based VLAN. With port-based VLAN, the port is assigned to a specific VLAN independent of the user or system attached to the port. This means all users attached to the port should be members in the same VLAN. The network administrator typically performs the VLAN assignment. The port configuration is static and cannot be auto
-
matically changed to another VLAN without manual reconfiguration. You can set up Port-Based VLAN using the method for 802.11Q. However, VID, PVID
or link type do not matter for Port-Based VLAN. Use the list command to check the status of the VLAN.

Quality of Service (QoS) refers to both a network's ability to deliver data with mini- mum delay, and the networking methods use d to co ntro l the use of bandwid th. Without QoS, all traffic date is eq ually lik ely to be dro pped when the netwo rk is conges ted. Thi s can cause a reduction in network performance and mark the network inadequate for a time-critical application such as video-on-demand.

-----------------------------------------------------------------------------
The Queue types are Weight Round Robin (WRR), Weighted Fair Queuing (WFQ), Best Effort (BE), and Strictly Priority (SP).
• Weight Round Robin (WRR): All rece ived packets will be stored into Queue 1, Queue 2, Queue 3, and Queue 4. Assign a weight value fo r ea ch queue. Then, WRR will re-assemble all packets from the four queues based on the weight assignments.
• Weighted Fair Queuing (WFQ): WFQ is a generalization of processor sharing, which allows several sessions to share the same link.
• Best Effort (BE): The BE Queue Type is used for data applications that have low priority or the potential to delay. BE does not use traffic priority or weight assignments, therefore BE is not recommended for high priority data, such as video or voice.
Strictly Priority (SP): The SP Queue Type uses queues that are based on priority only. SP transmits the highest priority queue first, then the next highest priority queue, and so on. However, if there is alway s some c ontent i n the hig hest pri ority qu eue, the n the other pac ket s in the res t of que ues w ill no t be se nt unti l the h ighes t priorit y queu e is

VLAN Tag Priority uses the tag field informati on which has bee n i ns erte d i nto an Eth er­net frame. If a port has an 802.1Q-compliant device attached (such as this Ethernet Extender), these tagged frames can carry VLAN membership information.
Priority defines the user priority level for different classes of traffic. There are 8 possi­ble priority levels, with 0 being the lowest priority level and 7 being the highest level. Each Priority level can be set queue from 0 to 3.
Table 25:
VLAN Tag Priority Levels
Priority Level Traffic Type
0 (default) Best Effort
1 Background 2 Spare 3 Excellent Effort 4 Controlled Load 5 Video, less than 100 milliseconds latency and jitter 6 Voice, less than 10 milliseconds latency and jitter 7 Network Control
For example, you can set the LB5 2xA-KIT to use W eighted Round- Robin (WRR) que u­ing (T yp e 1) that s pecif ies a re lative weight o f eac h queu e. WRR u ses a prede fin ed rel­ative weight for each queue that determines the percentage of time to service for each queue before moving on to the next queue.

IP DSCP Priority QoS
Differentiated Services (DiffServ) is a class of service (CoS) model that enhances best-effort Int ernet serv ices by dif fere ntiati ng traf fic by users , service requ iremen ts and other criteria. Packets are specifically marked, allowing network nodes to provide dif
­ferent levels of service, as appropriate for video playback, voice calls or other delay­sensitive applications, via priority queuing or bandwidth allocation.
The DSCP value used to identify 64 levels (26=64) of service determines the forward­ing behavior that each packet gets across the DiffServ network. Based on the marking rule different kinds of traffic can be marked for different priorities of forwarding.

5.8.7 DHCP
Dynamic Host Configuration Protocol (DHCP) is a communication protocol that allows network administrators to manage and automate the assignment of Internet Protocol (IP) addresses in an organization's network. Each machine that can connect
Page 90

Page 91
Console and Telnet Configuration
to the Internet needs a unique IP address. When an organization sets up the users with a connection to the Internet, an IP address must be assigned to each machine.
Without DHCP, the IP address must be entered manually at each computer. If comput­ers move t o another lo cation in another part of the network, a new IP address must be entered. DHCP lets a network administrator supervise and distribute IP addresses from a central point and automatically sends a new IP address when a computer is plugged into a different place in the network.
