2.1.2 miniGBIC SFP Fiber Optics

A gigabit interface converter (miniGBIC SFP) is a transceiver that converts electric currents (digital highs and lows) to optical signals, and optical signals to digital electric currents. The miniGBIC SFP is typically employed in fiber optic and Ethernet systems as an interface for high-speed networking. The data transfer rate is 1.25 gigabit per second. miniGBIC SFP modules allow technicians to easily configure and upgrade electro-optical communications networks. The typical miniGBIC SFP transceiver is a plug-in module that supports hot-plugging (it can be removed and replaced without turning off the system). The devices are economical, because they eliminate the necessity for replacing entire boards at the system level. Upgrading can be done with any number of units at a time, from an individual module to all the modules in a system. miniGBIC SFP (mini Gigabit Interface Converter), meet the Gigabit Interface Converter specification Rev. 5.4 (MOD_DEF4) industry standard.

3 Hardware Installation

This chapter describes how to install the XL-VC2402F and to establish network connection. You may install the VDSL concentrator on any level surface (table, shelf, 19-inch rack or wall mounting). However, please take note of the following minimum site requirements before you begin.
Pre-Installation Requirements
Before you start actual hardware installation, make sure you can provide the right operating environment, including power requirements, sufficient physical space, and proximity to other network devices that are to be connected. Verify the following installation requirement:
• Power requirements: AC 100V to 240 V at 50 to 60 Hz. The Switch power supply automatically
adjusts to the input voltage level.
• The VDSL concentrator should be located in a cool dry place, with at least 10cm/4in of space at
the front and back for ventilation.
• Place the VDSL concentrator out of direct sunlight, and away from heat sources or areas with a
high amount of electromagnetic interference.
• Check if network cables and connectors needed for installation are available.
General Rules Before making any connections to the VDSL concentrator, note the following rules:
• Ethernet Port (RJ-45): All network connections to the VDSL concentrator’s Ethernet port must be
made using Category 5 UTP for 100Mbps and Category 3,4 UTP for 10Mbps. No more than 100 meters (about 328 feet) of cabling may be use between VDSL concentrator’s or with HUB or an end node.
• VDSL Port (RJ-21): All home network connections to the VDSL, 1 X RJ-21 Cable (Male to
Male)Using Pin 1~24, 26~49. RJ-21 Pin 25 & 50 are not used!
Connecting the XL-VC2402F
The 24-port VDSL concentrator has 2 x Gigabit Ethernet supporting full or half-duplex operation. The transmission mode is using auto-negotiation. Therefore, the devices attached to these ports must support auto-negotiation unless they will always operate at half duplex. If transmissions must run at full duplex, but the attached device does not support auto-negotiation, then you should upgrade this device to a newer version that supports auto-negotiation. Use “25” port connect to devices such as server, bridge or router. You can also cascade to another compatible MUX or hub by connecting the 26 port to the other device. “Port 25” support 10/100/1000Giga RJ-45/miniGBIC SFP (fiber) Auto-Link. So you also can use Fiber Optic wire connect to Port 25 miniGBIC SFP side.
Connecting Ethernet Port
Ethernet Port “25” and “26” support auto MDI/MDIX. You can connect the “25 or 26” port on the VDSL concentrator to any device that uses a standard network interface such as a Cable modem, ADSL modem, Ethernet Switch, workstation or server, or also to a network interconnection device such as a bridge or router (depending on the port type implemented). Prepare straight through (or cross over) shielded or unshielded twisted-pair cables with RJ-45 plugs on both ends. Use 100Ω Category 5 cable for connections. Connect one end of the cable to “25” port of the VDSL concentrator, and the other end to a standard RJ-45 station port on cable modem, ADSL router, wireless bridge, etc. When inserting an RJ-45 plug, be sure the tab on the plug clicks into position to ensure that it is properly seated.
Notes: Make sure the length of twisted-pair cable is not over 100 meters (328 feet).
- 10 -
Connecting VDSL Port
Prepare the network devices you wish to connect. Make sure you have installed suitable VDSL Modem before making a connection to any of the VDSL concentrator (1-24) station ports. You also need to prepare one 18 ~ 26 gauge twisted pair phone Line wiring with RJ21 plugs at both ends. Connect one end of the cable to the RJ21 port of the Home Access network adapter, and the other end to any available (1~24) station port on the VDSL. Every port supports 4/1, 5/10/15 Mbps connections. When inserting an RJ21 plug, be sure the tab on the plug clicks into position to ensure that it is properly seated.
Notes:
• Be sure each twisted-pair cable (RJ-45) is not over 100 meters (328 feet)
• VDSL port use 18 ~ 26 AWG, 28 AWG or above is not recommended.

5.2.2 Advanced
5.2.2.1 Miscellaneous Settings
Mac Address Age-out Time： Type the number of seconds that an inactive MAC address
remains in the switch’s address table. The valid range is between 300∼ 765 seconds. Default is 300 seconds.
Max bridge transit delay bound control：Limit the packets queuing time in VDSL concentrator.
If enable，the packets queued exceed will be dropped. This valid value 1 sec、2 sec、4 sec and off. Default is 1 seconds.
Broadcast Storm Filter：To configure broadcast storm control, enable it and set the upper
threshold for individual ports. The threshold is the percentage of the port's total bandwidth used by broadcast traffic. When broadcast traffic for a port rises above the threshold you set, broadcast storm control becomes active. The valid threshold values are 5%, 10%, 15%, 20%, 25% and off.
Priority Queue Service settings: First Come First Service: The sequence of packets sent is depend on arrive order. All High before Low: The high priority packets sent before low priority packets. WRR: Weighted Round Robin. Select the preference given to packets in the switch's
high-priority queue. These options represent the number of high priority packets sent before one low priority packet is sent. For example, 5 High: 2 Low means that the switch sends 5 high priority packets before sending 2 low priority packet.
Enable Delay Bound: Limit the low priority packets queuing time in switch.
Default Max Delay Time is 255ms. If the low priority packet stays in switch exceed Max Delay Time, it will be sent. The valid range is 1~255 ms.
NOTE: Make sure of “Max bridge transit delay bound control” is enabled before enable Delay Bound, Because Enable Delay Bound must be work under “Max bridge transit delay bound control is enabled” situation.
QoS Policy: High Priority Levels: 0~7 priority level can map to high or low queue.

Protocol Enable Setting: Enable Spanning Tree Protocol: enable STP protocol Enable Internet Group Multicast Protocol: enable IGMP protocol
5.2.2.2 Interleaver depths
The Interleaving function reorganizes the bytes of the VDSL frames, dispersing them throughout the frames over the line. As a result, impulse noise that would normally appear sequentially is spread over several frames. This enables correction of a greater number of errors than would be possible if the bytes had been concentrated in a single frame.
The protected portion of the VDSL frame can be passed through a convolutional interleaver/deinterleaver. This protects the data, together with the RS coding, from impulse noise with duration of up to 300 µs at full rate. The total latency of the device consists of the latency caused by the RS encoding and the delay caused by interleaving. The parameter M is used to define the length of protection supported by the interleaving function. The value of if0le defines no use of the interleaver and the maximum value of 16 defines the maximum protection. The values 0,1,2,8 and 16 are valid. The registers M_TX and M_RX are used for the depth of the interleaver.

on this port and enable auto-negotiation), Force of per port.
Speed: User can set 4/1, 5Mbps/10Mbps/15Mbps from port 1~24, 1000Mbps, 100Mbps or
10Mbps speed on Port25~Port26 (base on copper mode, when fiber mode force on 1000Base-SX/LX)
Distance between VDSL & VDSL modem when standard 24 Gauge 0.5mm cable is used: 4/1 Mbps -> 1.9km. 5 Mbps -> 1.5km 10 Mbps -> 1.2km 15 Mbps -> 1.0km
- 23 -
Duplex: User can set full-duplex or half-duplex mode of per port. Flows control:
Full: User can set flow control function is enable or disable in full mode. Half: User can set backpressure is enable or disable in half mode.
Change Speed procedures:
a. Confirm the VDSL port is linking which you want to change the speed mode. b. Make sure VDSL port has been connecting to VDSL Modem and Link up OK. c. Select the port (there are 26 ports available) d. Select the speed mode e. Click “Apply” to confirm the settings f. The VDSL port will link down
g. Await 20 seconds the VDSL port will link up again with the new speed mode.
When the VDSL is linked up with the VDSL modem, both speed modes will be changed correspondingly. If the VDSL is not linked up with the VDSL modem, only the speed mode of the port selected from
VDSL will be changed.
Note: We do not suggest to change speed, unless necessary. Both VDSL & VDSL modem must be in the same speed mode in order to be linked successfully.
Rate Control: XL-VC2402F, port 1 ~ port 24, supports by-port ingress and egress rate control.
For example, assume Port 1 is 10Mbps, users can set it’s effective egress rate is 1Mbps, ingress rate is 500Kbps. VDSL concentrator will be performed flow control or backpressure to confine the ingress rate to meet the specified rate.
Ingress: Type the port effective ingress rate. The valid range is 0 ~ 100. The unit is 100K
0: disable rate control. 1 ~ 100: valid rate value (100=10Mbps)
Egress: Type the port effective egress rate. The valid range is 0~100. The unit is 100K.
0: disable rate control. 1 ~ 100: valid rate value.
Port Security: A port in security mode will be “locked” without permission of address learning.
Only the incoming packets with source MAC already existing in the address table can be forwarded normally. User can disable the port from learning any new MAC addresses, and then use the static MAC addresses screen to define a list of MAC addresses that can use the secure port. Enter the settings, then click Apply button to changes on this page.

5.5 Trunking

The Link Aggregation Control Protocol (LACP) provides a standardized means for exchanging information between Partner Systems on a link to allow their Link Aggregation Control instances to reach agreement on the identity of the Link Aggregation Group to which the link belongs, move the link to that Link Aggregation Group, and enable its transmission and reception functions in an orderly manner. In conclusion, Link aggregation lets you group up to eight consecutive ports into a single dedicated connection. This feature can expand bandwidth to a device on the network. LACP operation requires full-duplex mode, more detail information refers to IEEE802.3ad.
5.5.1 Aggregator setting
System Priority: A value used to identify the active LACP. The switch with the lowest value has
the highest priority and is selected as the active LACP.
Group ID: There are seven trunk groups to provide configure. Choose the "group id" and click
"Get".
LACP: If enable, the group is LACP static trunking group. If disable, the group is local static
trunking group All ports support LACP dynamic trunking group. If connecting to the device that also supports LACP, the LACP dynamic trunking group will be created automatically.
Work ports: Allow max four ports can be aggregated at the same time. If LACP static trunking
group, the exceed ports is standby and able to aggregate if work ports fail. If local static trunking group, the number must be assame as the group member ports. Select the ports to join the trunking group. Allow max four ports can be aggregated at the same time.
If LACP enable, you can configure LACP Active/Passive status in each ports on State Activity
page.
- 25 -
5.5.2 Aggregator Information
When you are setting LACP aggregator, you can see relation information in here. This page is no group active. LACP don’t working. This page is Static Trunking group.
- 26 -
5.5.3 State Activity
Active (select): The port automatically sends LACP protocol packets. Passive (no select): The port does not automatically sends LACP protocol packets, and responds
only if it receives LACP protocol packets from the opposite device.
A link having either two active LACP ports or one active port can perform dynamic LACP trunking. A link has two passive LACP ports will not perform dynamic LACP trunking because both ports are waiting for and LACP protocol packet from the opposite device.
If you are active LACP’s actor, when you are select trunking port, the active status will be created automatically.

5.6 Filter Database

5.6.1 IGMP Snooping
The XL-VC2402F supports IP multicast, you can enable IGMP protocol on web management’s switch setting advanced page, then display the IGMP snooping information in this page, you can view difference multicast group, VID and member port in here, IP multicast addresses range from
224.0.0.0 through 239.255.255.255.
The Internet Group Management Protocol (IGMP) is an internal protocol of the Internet Protocol (IP) suite. IP manages multicast traffic by using switches, routers, and hosts that support IGMP. Enabling IGMP allows the ports to detect IGMP queries and report packets and manage IP multicast traffic through the switch.
IGMP have three fundamental types of message as follows:
Message Description
Query
Report
Leave Group
A message sent from the carrier (IGMP router or switch) asking for a response from each host belonging to the multicast group. A message sent by a host to the carrier to indicate that the host wants to be or is a member of a given group indicated in the report message. A message sent by a host to the carrier to indicate that the host has quit to be a m ember of a specific multicast group.
- 28 -
5.6.2 Static MAC Address
When you add a static MAC address, it remains in the switch's address table, regardless of whether the device is physically connected to the switch. This saves the switch from having to re-learn a device's MAC address when the disconnected or powered-off device is active on the network again.
1. From the main menu, click administrator → Filter Database →Static MAC Address.
2. In the MAC address box, enter the MAC address to and from which the port should permanently
forward traffic, regardless of the device’s network activity.
3. In the Port Number box, enter a port number.
4. If tag-based (IEEE 802.1Q) VLANS are set up on the switch, static addresses are associated with
individual VLANS. Type the VID (tag-based VLANS) to associate with the MAC address.
5. Click add.
- 29 -
5.6.3 MAC filtering
MAC address filtering allows the switch to drop unwanted traffic. Traffic is filtered based on the destination addresses.
1. In the MAC Address box, enter the MAC address that wants to filter.
2. If tag-based (802.1Q) VLAN are set up on the switch, in the VLAN ID box, type the VID to
associate with the MAC address.
3. Click the Add.

5.7 VLAN configurations

A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain. It allows you to isolate network traffic so only members of the VLAN receive traffic from the same VLAN members. Basically, creating a VLAN from a switch is logically equivalent of reconnecting a group of network devices to another Layer 2 switch. However, all the network devices are still plug into the same switch physically. The VDSL concentrator support port-based and 802.1Q (tagged-based) VLAN in web management page. In the default configuration VLAN support is disabled.
NOTE:
If you change VLAN Operation Mode from No VLAN to 802.1Q, you must wait 50 seconds. Change VLAN mode for every time, you have to reboot the VDSL concentrator for valid value.
Support of Port-based VLAN :
Packets can go among only members of the same VLAN group. Note all unselected ports are treated as belonging to another single VLAN. If the port-based VLAN enabled, the VLAN-tagging is ignored.
Support of Tag-based VLAN (IEEE 802.1Q VLAN):
Tagged-based VLAN is an IEEE 802.1Q specification standard. Therefore, it is possible to create a VLAN across devices from different switch venders. IEEE 802.1Q VLAN uses a technique to insert a “tag” into the Ethernet frames. Tag contains a VLAN Identifier (VID) that indicates the VLAN numbers. In order to an end station to send packets to different VLANs, it itself has to be either capable of tagging packets it sends with VLAN tags or attached to a VLAN-aware bridge that is capable of classifying and tagging the packet with different VLAN ID based on not only default PVID but also other information about the packet, such as the protocol.

Ingress Filtering
Ingress filtering lets frames belonging to a specific VLAN to be forwarded if the port belongs to that VLAN. VDSL concentrator have two ingress filtering rule as follows: Ingress Filtering Rule 1: Forward only packets with VID matching this port's configured VID. Ingress Filtering Rule 2: Drop Untagged Frame.

5.8 Spanning Tree

The Spanning-Tree Protocol (STP) is a standardized method (IEEE 802.1D) for avoiding loops in switched networks. When STP enabled, to ensure that only one path at a time is active between any two nodes on the network. You can enable Spanning-Tree Protocol on web management’s switch setting advanced item, select enable Spanning-Tree protocol.

6 Applications

The VDSL provides home network architecture. Transforming an apartment into a Multiple-Family Home network area, sharing a single internet account for multiple users with Router & Cable Modem, it can provide unlimited access time in the internet at a reasonable low price.
Bridging Functions – The XL-VC2402F provides full transparent bridging function. It
automatically connects node addresses, that are later used to filter and forward all traffic based on the destination address. When traffic passes between devices attached to the shared collision domain, those packets are filtered from the VDSL concentrator. But when traffic must be passed between unique segments (i.e., different ports of the VDSL concentrator), a temporary link is set up between the VDSL concentrator’s port in order to pass this traffic, XL-VC2402F (the high-speed VDSL fabric).
Transceiver function - The XL-VC2402F supports Ethernet to VDSL convert, It can be transmit
or receive packet from Ethernet port to the RJ21 port. Or VDSL port to Ethernet port.
Flexible Configuration –The XL-VC2402F is not only designed to segment your network, but
also to provide a wide range of options in the configuration of Home network connections. It can be used as a simple stand-alone VDSL concentrator; or can be connected with another VDSL concentrator, Cable modem, Router, XDSL, ISDN, gateway or other network interconnection devices in various configurations. Some of the common applications of the VDSL concentrator are described in this chapter.

7 Appendix

7.1 Appendix A: Troubleshooting

7.1.1 Diagnosing VDSL Indicators
The VDSL can be easily monitored through its comprehensive panel indicators. These indicators assist the network manager in identifying problems of the VDSL concentrator may encounter.
This section describes common problems you may encounter and possible solutions
Symptom: POWER indicator does not light up (green) after power on. Cause: Defective power outlet, power cord, internal power supply Solution: Cheek the power outlet by trying another outlet that is functioning properly. Check the power cord with another device. If these measures fail to resolve the problem, have the unit power supply replaced by a qualified distributor.
Symptom: Link indicator does not light up (green) after making a connection. Cause: Network interface (e.q., a network adapter card on the attached device), network cable, or switch port is defective. Solution:
1. Verifies the switch and attached device are powered on.
2. Be sure the cable is plug into both the switch and corresponding device.
3. Verify that the proper cable type is used and its length does not exceed specified
limits.
4. Check the adapter on the attached device and cable connections for possible
defects.
5. Replace the defective adapter or cable if necessary.
Symptom: VDSL Link can not be established. Cause: Rusted phone wire, not standard 24 gauge phone wire, not twisted-pair phone wire, wrong speed mode. Solution: Check if speed of CO and CPE is in the same speed mode
depth value to 8 or above.
else please increase interleaver
7.1.2 System Diagnostics
Power and Cooling Problems
If the POWER indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or internal power supply as explained in the previous section. However, if the unit should turn itself off after running for a while, check for loose power connections, power losses or surges at the power outlet, and verify that the fan on back of the unit is unobstructed and running prior to shutdown. If you still cannot isolate the problem, then the internal power supply may be defective. In this case, contact your supplier for assistance.
Installation
- 45 -
Verify that all system components have been properly installed. If one or more components appear to be malfunctioning (e.g., the power cord or network cabling), test them in an alternate environment where you are sure that all the other components are functioning properly.
Transmission Mode
The selections of the transmission mode for the RJ-45 ports are auto-negotiation using the default method. Therefore, if the Link signal is disrupted (e.g., by unplugging the network cable and plugging it back in again, or by resetting the power), the port will try to re-establish communications with the attached device (auto-negotiation). If auto-negotiation fails, then communications are set to half duplex by default. Based on this type of industry-standard connection policy, if you are using a full-duplex device that does not support auto-negotiation, communications can be easily lost (i.e., reset to the wrong mode) whenever the attached device is reset or experiences a power fluctuation. The best way to resolve this problem is to upgrade these devices to version that will support auto-negotiation.
Cabling
Verify that the cable type is correct. Be sure RJ-45 cable connectors are securely seated in the required ports. Use 100Ω straight-through cables for all standard connections. Use Category 5 cable for 100/1000Mbps Fast Ethernet connections, or Category 3, 4 or 5 cables for standard 10Mbps Ethernet connections. Be sure RJ21 phone wiring, use 18~26 gauge. Make sure all devices are connected to the network. Equipment any have been unintentionally disconnected from the network.
When cascading two devices using RJ-45 station ports at both ends of the cable (XL-VC2402F) supports auto MDIX), without crossover cable can be used.
Physical Configuration
If problems occur after altering the network configuration, restore the original connections, and try to track the problem down by implementing the new changes, one step at a time. Ensure that cable distances and other physical aspects of the installation do not exceed recommendations
System Integrity
As a last resort verify the switch integrity with a power-on reset. Turn the power to the switch off and then on several times. If the problem still persists and you have completed all the preceding diagnoses, contact your dealer for assistance.

7.4.2 802.1Q Tag Vlan
Tagged-based VLAN is an IEEE 802.1Q specification standard. Therefore, it is possible to create a VLAN across devices from different switch venders. IEEE 802.1Q VLAN uses a technique to insert a “tag” into the Ethernet frames. Tag contains a VLAN Identifier (VID) that indicates the VLAN numbers. In order to an end station to send packets to different VLANs, it itself has to be either capable of tagging packets it sends with VLAN tags or attached to a VLAN-aware bridge that is capable of classifying and tagging the packet with different VLAN ID based on not only default PVID but also other information about the packet, such as the protocol.
This page, user can create Tag-based VLAN, and enable or disable GVRP protocol. There are 256 VLAN groups to provide configure. Enable 802.1Q VLAN, the all ports on the switch belong to default VLAN,VID is 1. The default VLAN can’t be deleted and modified.
- 51 -
GVRP (GARP [Generic Attribute Registration Protocol] VLAN Registration Protocol) GVRP allows automatic VLAN configuration between the switch and nodes. If the VDSL concentrator is connected to a device with GVRP enabled, you can send a GVRP request using the VID of a VLAN defined on the VDSL concentrator, the VDSL concentrator will automatically add that device to the existing VLAN.
Port VID Configure port VID settings
From the main Tag-based (IEEE 802.1Q) VLAN page, click Port VID Settings.
Port VID (PVID)

Ingress Filtering
Ingress filtering lets frames belonging to a specific VLAN to be forwarded if the port belongs to that VLAN. The XL-VC2402F has two ingress filtering rules as following: Ingress Filtering Rule 1: Forward only packets with VID matching this port's configured VID. Ingress Filtering Rule 2: Drop Untagged Frame.
Example 1:
4 users join to Internet by VDSL system like following drawing, and have 7 demands.
1) User A connect to port 1 and join to Internet through port 26
2) User B connect to port 2 and join to Internet through port 26
3) User C connect to port 3 and join to Internet through port 26
4) User D connect to port 4 and join to Internet through port 26
5) User A isolate with Users B, C and D 6) User B isolate with Users A, C and D
7) User C and D in same Group and isolate with Users A and B
Setup Procedure: Setup Port VID: Assign a Port VLAN ID (1~4094) for untagged traffic on each port like following: Port 1 PVID=21, Port 2 PVID=22, Port 3,4 PVID=23
Add VLAN Group:
1) Do not change the default_1 group.
2) Add a VLAN Group VID=21 member ports = port 1 & port 26
2.1) Setup VLAN Name=UserA, VID=21, select member ports 1 & 26

2.2) Select Untag or Tag Setup. Unless the device( computer or switch) which connect to port 1 or
port 26 can support Tagging VLAN, otherwise select Untag.
3) Add a VLAN Group Name=UserB, VID=22 member ports = port 2 & port 26 4) Add a VLAN Group Name=UserCD, VID=23 member ports = port 3, port 4 & port 26
