3 General Application Notes The IES is an IP-based DSLAM (Digital Subscriber Line Access Multiplexer) that connects subscribers to the Internet. As a high-performance yet compact platform, it conveniently gives telephone companies and Internet Service Providers (ISPs) the ability to deliver broadband Internet access and voice services to subscribers. The IES platform allows for convenient management and support of various technologies. As the IES serious models, IES-5106M provides different DSL port speeds to different subscribers. In order to satisfy the different demand on connection requirement for the subscribers, an ISP might need to set different line speed for each DSL port. The IES-5106M can provide a proper solution to handle it by creating some profiles and setting different parameters for different users connections.

4 The comparison of IES serious models Number of line cards For different regions, number of subscribers, and the management on business budge and profit, the telephone companies and ISPs need a most economical and efficient DSLAM to cover their regional service. ZyXEL s IES serious products provide various options of DSL solutions for ISPs and telephone companies to choose the best model which is suit for their business. The IES-5106M can hold a maximum of five line cards, so up to 240 subscribers (360 when using the ALC port line card) can simultaneously utilize a wide range of powerful broadband services. IES-5106 IES-5012 IES-6000 number of total slot number of management slot max VDSL subscribers max ADSL subscribers (ALC-1272) Table 1. The comparison table with other IES models. The ISP can deploy the IES-5106 for a moderate amount of subscribers regionally to gain the most benefit from using IES The compatibility for MSC cards. As the various options for downstream line cards, the ISPs also have different requirements on the upstream links, such as Gigabit Ethernet port, Gigabit Ethernet SFP slot, Gigabit Ethernet XFP slot, or even 10 Gigabit Ethernet SFP+ slot. IES-5106 supports MSC1024GB and MSC1224GB serious management cards. Each management card has its own features for different uplink requirements and also has different features to other serious management cards, such as MSC1024G and MSC1224G.

13 Application Scenario 1 - Multi-Services on VLC line card The following example demonstrates a Triple Play service configuration running Data, VoIP, IPTV and TR069 services on respective WAN interfaces. The ISP can refer to this scenario to provide multiple services to its subscribers and also have the convenience and efficiency to maintain its devices and network. The following figure is a simplified overall scenario diagram of Multi-Service topology. 1. In this scenario, we use VLAN 695 for IPTV service, VLAN 696 for TR069 remote management, VLAN 697 for VoIP service and VLAN 698 for internet service. 2. Configure proper VLANs on IES-5106M: Go to VLAN. In the VLAN Setup page, enable the VLAN, set the name as 695, set the VID as 695, select Fixed for the uplink Ethernet port and select Tag for the uplink port as well. Click Apply to save the configuration.

14 3. Repeat step 2 to create VLAN 696, 697 and 698 with the same configuration except the name and VID. Please input the correct name and VID for each VLAN. 4. After creating these VLANs properly, you can find the created VLANs are displayed in the VLAN list. Please double confirm that these VLANs are set correctly with Tag. 5. Enable DSL port and set VLAN on DSL port: Go to Port -> VDSL, select the slot number of the VLC line card and the connect port to the CPE, and then click Load to load the current configuration on this port. In this case, the VLC line card in on slot #1 and the DSL port is #2.

15 6. Select Enable and click Apply to enable this port for DSL service. If the downstream CPE has connected to the VLC line card, the DSL LED should start to blink with orange light, which means that the physical DSL connection is working but the traffic is not through yet. The reason is that the VLAN setting is not finished. 7. Click VLAN Setup to set VLAN for this DSL port.

16 8. In page VALN Setup 1 2, input 695 for VID, select join for Registration and select Tag. And click Apply to add VLAN 695 for this DSL port. 9. Repeat step 8 for adding VLAN 696,697 and 698 with the same setting except the VID. Please input the correct VID for each VLAN. 10. After adding these VLANs properly, you can find the added VLANs are displayed in the VLAN list. Please double confirm that these VLANs are set correctly with correct VID and Tag.

17 11. In order to double confirm the VLANs are set correctly on this DSL port, please go to VLAN -> Port Setting, and click the slot number of the VLC line card. 12. You can see the VLAN setting is correct on the DSL port.

18 13. Now, the IES-5106M is able to pass through the traffic for both upstream and downstream with VLAN tags. 14. Please ensure that the VLAN setting on the switch and CPE are both correct, and then the traffic of different services would be directed to correct network and this scenario is able to provide multiple service on different WAN interfaces.

19 IP Multicast Introduction What is the IP Multicast? Traditionally, the IP packets are transmitted in two ways: unicast or broadcast. Multicast is a third way to deliver the IP packets to a group of hosts. Host groups are identified by the class D IP addresses, i.e., those with "1110" as their higher-order bits. In dotted decimal notation, host group addresses range from to Among them, is assigned to the permanent IP hosts group, and is assigned to the multicast routers group. The IGMP (Internet Group Management Protocol) is the protocol used to support multicast groups. The latest version is version 2 (See RFC2236). The IP hosts use the IGMP to report their multicast group membership to any immediate-neighbor multicast routers, so the multicast routers can decide if a multicast packet needs to be forwarded. At the start-up, the Prestige queries all directly connect networks to gather group membership. After that, the CPE updates the information by periodic queries. The device implementation of IGMP is also compatible with version 1. The multicast setting can be turned on or off on the Ethernet and remote nodes.

20 Application Scenario 2 Configure IPTV on ELC Topology: In this scenario, we use VLAN 69 for Internet service, VLAN 99 for IPTV service and VLAN 3888 for MVLAN through ELC port. The follow configuration steps would focus on the setting on ELC line card. 1. Configure proper VLANs on IES-5106M: Go to VLAN. In the VLAN Setup page, enable the VLAN, set the name as 99, set

21 the VID as 99, select Fixed for the uplink Ethernet port and select Tag for the uplink port as well. Click Apply to save the configuration. 2. Repeat step 1 to create VLAN 69 with the same configuration except the name and VID. Please input the correct name and VID for each VLAN. 3. After creating these VLANs properly, you can find the created VLANs are displayed in the VLAN list. Please double confirm that these VLANs are set correctly with Tag. 4. Go to Port -> Enet

22 5. Select Slot 3 and Port 1 (in this case, the ELC line card is in slot 3 and we use port 1 for downstream connection), then click Load button. 6. Click VLAN Setup button to VLAN Setup: 3-1 page. Input PVID as 99 then click Apply. VLAN 99 would be displayed in the VLAN list below.

23 7. Go back to Port -> Enet, and select Slot 3 and Port 1 then click load. You can see that PVID has been set to 99. Select Enable then click Apply to enable this port. 8. Add a multicast VLAN When user send an IGMP join via VLAN 99, the DSLAM will change it to multicast VLAN Go to Multicast -> MVLAN 10. Select Enable, set the Name as VLAN3888, VID as 3888, and then click Apply to add the MVLAN. VLAN 3888 would be displayed in the VLAN list below.

24 11. Click hyperlink 3 for the slot number of ELC line card, a new Web page will pop up. 12. Select Fix for port 1 which is the port on ELC for downstream connection, and then click Apply.

25 13. Click hyperlink 3888, in the MLAN Setup page. 14. Add multicast address range which depends on the IPTV service. Here we use ~

26 15. Go to Multicast -> IGMP. 16. In tag IGMP Setup, Select Enable IGMP Snooping for IGMP mode, and then click Apply.

27 17. Now, the setting of IGMP multicast service on IES-5106M is finished. If the VLAN setting on the uplink switch and downstream CPE are set correctly, the IPTV service with multicast group should work properly in this scenario.

To exit engineering mode, press CTRL and S keys at the same time again on your computer.

32 Line card CLI mode To access CLI mode of line card, give command lcman debug <slot #> in MSC engineering mode. For example, to enter CLI mode with line card that is installed in slot 4, give command lcman debug 4. To return to MSC engineering mode, type exit command. Freeze Descriptions:

33 Freeze means the TV holds and stops flowing. Freeze happens when IGMP packet is dropped or IGMP protocol is having problem. Freeze is not Mosaic. For Mosaic issue, please refer to Mosaic. Generic network topology IPTV server L3 switch DSLAM CPE Set-top box Diagnosis: Start by finding out the exact problem: Did the subscriber have freeze before? Did the freeze happen in certain channels? Or the freeze happened to random channels? How long does the freeze last? How does the freeze stop? The freeze disappeared by itself or subscriber must switch to another channel? Did the subscriber change the CPE or STB recently? What is the IGMP setting of CPE? Proxy or snooping? What is the IGMP setting of STB? IGMPv2 or IGMPv3? How long is the CPE IGMP query interval? How many STB are connecting to the CPE? One STB to one CPE or two STB to one CPE? How many IPTV subscribers are there in the chassis DSLAM? How many IPTV channels are there in total? Is there any other traffic other than IPTV packet?

34 Possible Causes with Solution Possible cause Solution Source channel has Please inform IPTV service provider delay CPE setting is not Follow the setting of other CPEs compatible STB setting is not Follow the setting of other CPEs compatible DSLAM setting is not Please add static query VLAN for IGMP router optimized Two STBs connecting to Please try line card FCS FW: 396UHA1C0 for one CPE ALC1272G-51 Freeze disappears by Please try decrease the CPE query interval to be itself smaller than DSLAM s. (150s????) If everything is ok, proceed with the following procedure. Symptom: Freeze is observed before DSLAM In this situation, we observed the Freeze on the STB connected to the L3 Switch directly. IPTV server L3 switch DSLAM CPE Set-top box Set-top box Set-top box Possible cause Outcome Solution

35 IGMP packet drop happens in the network TV channel freeze Inform IPTV service provider to check where the IGMP packet drop happens in the aggregation or in the core network Symptom: Freeze is observed before CPE In this situation, the STB on L3 Switch is without Freeze; but the STB has Freeze which is connected to another uplink interface on DSLAM. IPTV server L3 switch DSLAM CPE Set-top box Set-top box Set-top box Possible cause Outcome Solution MSC fails to handles all IGMP Freeze until next query arrives Disable MSC CPU protection by giving command eng ether bw switch 0 query MSC CPU Freeze until CPU Give debug command sys cpu disp in MSC utilization high Line card CPU utilization high resource free-up Freeze until CPU resource free-up engineering mode, check the following picture Give debug command sys cpu disp in Linecard CLI mode, check the following picture

36 Symptom: Freeze is observed after DSLAM In this situation, both STBs on DSLAM and L3-Switch are without problem; but the STB behind the CPE has Freeze.

37 IPTV server L3 switch DSLAM CPE Set-top box Set-top box Set-top box Possible cause Outcome Solution CPE IGMP proxy/snooping compatibility Freeze snooping, please change to proxy. CPE IGMP version compatibility CPE IGMP query interval not long enough Freeze Freeze Change CPE IGMP setting; if it is proxy, please change to snooping. If the current setting is Change CPE IGMP setting; if it is v2, please change to v3. If the current setting is v3, please change to v2. Increase CPE IGMP query interval CPE is broken Freeze Replace old CPE with a new, functional one Symptom-1: (Two or more TV channels) Freeze happens when other TV is switching to another channel; freeze disappears only after another channel switching e.g. Two TVs are watching the same channels, one TV switches the channel to another, another TV gets Freeze, unless it switches the channel too. Possible cause Outcome Solution STB did not Freeze Get trace between CPE & STB when freeze

38 handle the IGMP query correctly DSLAM did not handle the IGMP query correctly Freeze happens. Freeze must be more than three times during trace recording. Try FCS FW version. STB is broken Freeze Replace old STB with a new, functional one Symptom-2: none of the above Possible cause Outcome Solution Unknown Freeze Get trace between CPE & STB when freeze happens. Freeze must be more than three times during trace recording. Mosaic Descriptions: Mosaic means the part of the TV screen is showing Mosaic. Mosaic happens when packet is dropped within the network. Mosaic is not Freeze. Diagnosis: Start by finding out the exact problem: Is the IPTV subscriber also subscribing internet service? Is there any internet service/application running when Mosaic happens? What is the required bandwidth of the IPTV service? Is there any QoS to differentiate IPTV and internet traffic? How is the traffic performance when Mosaic happens? What is the performance of the CPE? Is there any CRC error? Does the Mosaic always happen in the same channel? Or Mosaic happens in all channels? Possible Causes with solution Possible cause Solution CPE is broken Replace the old CPE with a new, functional one Wire/connection is Replace the cable or wire until there is no CRC error loose Bandwidth limitation Please consult with IPTV or internet service provider if the actual bandwidth is lower than required bandwidth for IPTV service No QoS between IPTV Give higher QoS for IPTV traffic, please refer to ATM

39 traffic and other traffic QoS feature for ALC/SLC-card solution, or refer to IPQoS feature for VLC / ELC-card solution. Please resort to CSO on ITS for the detail configuration if you have any question about the QoS setting. If everything is ok, proceed with the following procedure. Symptom: Mosaic happens during heavy traffic hour (peak hour) Possible cause Outcome Solution Packet drop due to heavy traffic Mosaic Capture packet between CPE & STB, and between CPE and DSLAM, and between DSLAM and L2 switch at the same time, to see if there is any packet loss Symptom: Mosaic happens during light traffic hour (non-peak hour) Possible cause Outcome Solution Bandwidth Mosaic Consult IPTV and internet service provider limitation policy

40 Configure IPv6 multicast packets pass through IES-5106M IPv6 uses multicast to replace broadcast in IPv4. That means there are only unicast packets and multicast packets in IPV6 traffic and no broadcast traffic in IPv6. multicast unicast multicast unicast Static MAC Multicast Screen is designed for non-ipv4 static multicast traffic (such as IPv6 static multicast traffic). DHCPv6 example:

41 Unicast can be studied easily by our DSLAM, there is no problem. However, in the sample, the corresponding IPv6 multicast MAC address is 33:33:00:01:02, this kind of MAC address is IPv6 multicast s MAC address; it cannot be learned by DSLAM automatically. Therefore, we should add this MAC address into corresponding DSL ports and uplink ports. We suggest to add the following multicast into our DSLAM s tested DSL ports: 1. 33:33:ff:[Last three bytes of PC MAC address] 2. 33:33:00:00:00: :33:00:01:00:02 (for DHCPv6) The following steps show how to configure IPv6 multicast packets pass through IES- 5106M by Telnet connection: 1. Connect to the IES-5106M by Telnet and login as admin/ Before starting configure IPv6 multicast packets pass through, we can type: MSC1224BG> multicast groupmacaddr show

42 to check the Static MAC Multicast status. As we can see, there is no Static MAC Multicast. 3. Add the IPv6 multicast address: 33:33:00:01:00:02 (for DHCPv6)for VLAN 1 for the uplink ports on MSC1224GB by typing: MSC1224BG> multicast groupmacaddr set 1 all fix

43 Then check the Static MAC Multicast status again, we can see that the uplink port on MSC1224GB (slot 6) are all fixed for VLAN Add the IPv6 multicast address: 33:33:00:01:00:02 (for DHCPv6)for VLAN 1 for all of the downlink ports on VLC1348G-51 (slot 1) by typing: MSC1224BG> multicast groupmacaddr set 1 33:33:00:01:00:02 1-* fix

44 Then check the Static MAC Multicast status again, we can also see that all of the downlink port on VLC1348G-51 (slot 1) are all fixed for VLAN We can also check the MAC Multicast status on GUI. Go to Multicast -> Static MAC Multicast We can verify that the MAC address for IPv6 multicast is in the list of Static MAC Multicast and able to pass through IPv6 multicast packets. 6. Repeat steps 3 to 4 to add Static MAC Multicast for other IPv6 multicast address 33:33:ff:[Last three bytes of PC MAC address] and 33:33:00:00:00:01 to make IES-5106M able to pass through the IPv6 multicast packets.

45 Application Scenario 3 - EFM SHDSL Solution Introduction ZyXEL EFM SHDSL Solution helps Service Providers to have IP End to End Solution. Ethernet in the First Mile (EFM), also known as IEEE 802.3ah, is a collection of protocols specified in IEEE 802.3, defining the Ethernet in the access networks, i.e. first or last mile. With wide, metro and local area networks already standardized, the EFM allows continuous standard Ethernet network across the globe, eliminating non-native transport such as Ethernet over ATM from the access networks. EFM defines how Ethernet can be transmitted over new media types: Voice-grade copper. These new EFM copper (EFMCu) interfaces allow optional multi-pair aggregation Long wavelength single fiber (as well as long wavelength dual-strand fiber) Point-to-multipoint (P2MP) fiber. These new interfaces are known under collective name Ethernet over passive optical networks (EPON).

46 Network Topology: Network topology is like above, the line card SLC1348G-22 is plugged in slot 1. Switch A, which connected to IES-5106M s uplink port, and switch B, which connected to SLC line card, can ping with the VLAN header which is to similar the scenario that the service provider provided to the business customer. The management IP for Switch A is with VLAN 200 The management IP for Switch B is with VLAN 200

47 ATM Mode Configuration CO side: 1. VLAN settings in IES-5106M Create a new VLAN which VLAN ID is 200; enable Tx Tagging in Ethernet port which connected to the Ethernet switch A. 2. PVC settings: Go to Port -> PVC, create a PVC VPI/VCI is 0/33 PVID 1 on the SLC (slot 1) port 1.

48 Click the index 1 link, below screen will appear, you can make the VPI/VCI 0/33 join the VLAN 200 and checked the Tag to make sure the traffic with VLAN 200 will be sent out with VLAN header.

49 3. Port setting Go to Port -> SHDSL, Slot 1 port 1, set the transmission convergence as atm.

50 ATM Mode configuration CPE side: 1. WAN Internet Access setup: Transfer Mode is ATM, Encapsulation is RFC 1483 and VPI/VCI is 0/33

51 Q/1P settings: Modify the default group 1 to enable Tx Tagging in LAN 1.

52 Create a new group name test, VLAN ID is 200, default Gateway is PVC1 and LAN 1 join this VLAN and Tx Tagging enabled. PVC1 also join this VLAN Tx Tagging enabled. PC A can t recognize packet with VLAN, therefore for LAN 2, the Tx Tagging should not be enabled.

53 The final group status should like below: 3. Change the PVID for LAN port 2, change to VLAN 200 for PC A.

54 Test from Switch A: In Switch A as you can see the IP settings and also test result of PING and the result is OK.

55 EFM Mode configuration CO For EFM mode, there are three steps to finish the setting based on the ATM settings. 1. Change the Transmission Convergence mode to EFM in IES-5106M.

56 2. Change the Transfer mode to PTM in P-793H v2. 3. Modify the PVID for PVC setup page. Since in EFM mode there is no VPI/VCI, we still need to use this page to define the PVID or default priority for the port. At the PVC setting page, click index link.

57 Same with the ATM mode setting, make PVC 0/33 join VLAN 200 and Tag must be checked to make sure traffic with VLAN 200 would be sent out with the same VLAN ID in VLAN header.

58 Test from Switch A: In Switch A as you can see the IP settings and also test result of PING and the result is OK.

59 Application Scenario 4 - VDSL fallback to ADSL xdsl fall back provides the ISP increased interoperability with different xdsl CPEs and flexibility so they can now, depending on the distance and bandwidth requirements, offer different services to different customers using the same line card. In the following sample, we will show how to establish an ATM connection through a VDSL line card. Topology: 1. Go to Port -> VDSL, select the slot and port number for VLC line card and the port which connected to the CPE, and then click load. In this sample, the slot is 4 and port number is 1.

60 2. Enable this port and select mode as adsl2+ in VDSL Profile, and then click Apply. 3. Go to Port -> PVC, select Slot 4 and Port 1 then click Load to load this port s setting. 4. Set the PVC for this port as VPI/VCI as 0/33, and then click Apply.

61 The setting for VDSL fallback to ADSL on IES-5106M is finished. 5. On the CPE, we can simple establish an ATM interface to verify if the fallback feature worked or not. 6. Create an ATM interface on the CPE with the VPI/VCI as 0/ Then the CPE is able to establish an ATM connection to the internet through VLC line card by the feature of xdsl fallback.

63 Application Scenario 5 - DSL Bonding DSL Bonding Introduction What is the DSL Bonding? The basic theory behind bonding ADSL/VDSL lines is the idea that combining two separate ADSL/VDSL connections to connect to one computer should double your bandwidth and thus double your connection speeds. The solution currently being utilized is to connect two ADSL/VDSL lines to one router. For this to work, you need a specially designed router, such as the P-873HNUP-51B. ADSL/VDSL Bonding takes two copper based lines per subscriber and aggregates them to almost double the bandwidth speed available to the existing customers and also expands high speed broadband access to areas that are underserved today. Using ADSL/VDSL Bonding technology, service providers can extend the life of their existing copper infrastructure supporting the delivery of bandwidth intensive services such as Triple play service, data and IPTV. Pair bonding isn't just about speed -- it's about reaching more customers at ever-greater distances.

64 Topology: DSL Bonding configuration on IES-5106M 1. Go to Port -> ADSL, select the slot and port number for ALC line card and the port which connected to the CPE, and then click load. In this sample, the slot is 2 and port number is 1 and 2; we would show the setting for port 1 first.

65 2. Click Apply to enable port Repeat steps 1 to 2 to enable port 2 as well. 4. Go to Port -> PVC, select the slot and port number for ALC line card and the port which connected to the CPE, and then click Load. In this sample, the slot is 2 and port number is 1 and 2; we would show the setting for port 1 first.

66 5. Set the PVC for this port as VPI/VCI as 0/33, and then click Apply. 6. Repeat steps 4 and 5 to set PVC 0/33 for port 2 as well. 7. Go to Port -> G.bond 8. In the G.bond setup page, select the slot for ALC line card, in this case is slot 2, give this G.bond group a name as test.

67 9. Click the none link, the Select Member Ports page would pop up. Select the ports which we would like to bond together, and then click Apply. In this case, we bonded port 1 and The port 1 and 2 would be showed on the Member Port list. Click Apply to add the G.bond group. 11. The setting for G.bond on IES-5106M is finished.

68 DSL Bonding on CPE 1. Before we set the G.bond feature on IES-5106M, there is only one connection established, and the bandwidth on the CPE (P-873HNUP-51B) is RX:23994/TX:999(Kbps). 2. After we set the G.bond feature on IES-5106M, the two ADSL connections are bonded together, and the bandwidth on the CPE (P-873HNUP-51B) is doubled to RX:47982/TX:1998(Kbps).
