Features and Functions Port 1 (eth1) – Out of Band management port only. Connected physically and logically only to the IP/SCP. Port 2 & 3 (eth2 & 3) – Can be used for either customer data as well as in-band management traffic. Eth2 – is a copper 10/100meg connection Eth3 – is either copper or fiber GigE connection (1000) only By default eth2, eth3 and all of the DSL ports are all assigned to VLAN 1. The switch cannot filter on well know IP port numbers. The switch can be configured so that each DSL port can have up to 8 VPI/VCI connections. Each VPI/VCI can be assigned to a unique VLAN. Each ATM connection / VLAN can be assigned different levels of priority (8 highest, 1 lowest). All ATM traffic over the DSL link is UBR. End to end quality of service is done through VLAN groups using the eight port queues (ATM queue number).

Features and functions (continued) The IP/SCP is designed to fit into the following networks: Private MTU Networks and Telco Networks Video applications can only be supported by the 8965 ADSL (this is due to the fact that video applications require a minimum of 3.5 to 4 Meg connection per video stream). There are three different modes of operation for the internal layer 2 switch. These modes of operation are mutually exclusive. By default all Ethernet switches must have at least one group or VLAN that is active. In the case of the IP/SCP VLAN 1 is active for Secure VLAN and Switch modes of operation. In the case of Uplink Tagging each DSL port is assigned a unique VLAN. Secure VLAN This is the default mode of operation, which performs security between DSL ports. All traffic from a DSL port is directed to the uplink. There is an additional Ethernet management port, which is for out of band management for the unit, which has a default IP address of 10.10.10.10. Switch Mode This is basic Ethernet switching where all ports have equal access. Uplink Tagging The default for this mode is that each DSL port is assigned to a unique VLAN and that the uplink will be using 802.1Q tagging to distinguish between ports.

Triple Play Network 802.1P – The IP network that is connected to the IP/SCP must support both 802.1Q tagging (where multiple logical connections are supported by a single physical connection), and 802.1P which is prioritizing of traffic over Ethernet. This network will have connections to the following devices and or networks: Video middleware server – supplies the STB with code and channel guide Multicast head end – supplies the MPEG encoded live content VOD servers – supplies the local VOD server with additional pay per view MPEG video content VoIP Gateway / Softswitch – supplies the voice connection back to the PSTN Internet ISP – supplies the high speed Internet connection SNMP Management – control for the CO connected devices Ethernet switch – must support the following: 802.1P prioritization 802.1Q (Cisco refers to this as trunking) – a minimum of four VLANs are required to support triple play (Video [multicast and unicast], voice and Internet) IGMP Version 2 IGNP querier – sends an IGMP multicast query to the STB to see if a multicast channel is still being used (this would only be used on the port going to the 4200IP/2600 VOD Server – this can supply either all of the VOD content or it can supply only a portion of the VOD content. The portion of the VOD content could be anything from a video clip to a portion of the movie. This is based on multiple factors, first is that in some cases content providers require you to pay royalties based on the number of copies of a video, how big and how many servers do you want to deploy, and how much bandwidth do you have available with in your network. IP/SCP Ethernet Port – 802.1P will start and stop at this interface and 802.1Q, minimum of four VLANs configured DSL Port – will have four VCCs configured each with a different priority (must match the 802.1P from the Ethernet interface), voice having the highest priority CPE – must be an Ethernet switch device that supports VCC to Ethernet port mapping. Two VCC connections will be assigned to the port that has the STP attached. These two connections are for the unicast and multicast video streams. STB – can be either thin client (HTML) or thick client (JAVA) and must support the following: Middleware server VOD server Multicast headend



Out of Band Management• SCP Console (A) – 9600, 8, 1, N, No Flow

Control (cable and adapter are supplied with SCP)• Default IP = 10.10.10.10• Login – SUPERUSER• Password – ASN#1500• Commands –

– configure management out-of-band address 10.10.10.10 255.255.255.0

– configure management default-gateway 10.10.10.1



Out of Band Management Access The SCP uses the same cable and adapter that was used by the MCP. You now will have to plug it into the Serial SCM (SCP) port. Both slot A and B can be accessed. The only SCP that responds is the active one.



IP/SCP Switch Capacity• SCP – 2.4 Gig• ADSL2+ – 200 Meg Down and 50 Meg Up• Reach – 18 Meg • SHDSL – 50 Meg Up and Down



IP/SCP Switch Capacity IP/SCP – Performs all policing and CAC at the DSL ports and VLAN tagging and queuing on the Ethernet side. CAC for CBR is 100% (not displayed), for rt/vbr & nrt/vbr is defaulted to 200% Throttling of traffic can be done for both versions of VBR Configuration changes are done in real time to both SCPs. Ethernet and ATM switching are only done on the IP/SCP. Firmware and configurations only exist on the SCP.



Configuration Menu



Configuration Menu The configuration menu reflects the cards that are discovered by the SCP The following is the order that will be used during this module; Management System Ethernet (physical uplink) Reach/ADSL SHDSL DSL Connections Multicast (only if you will be supporting multicast video)



Management Menu



Management Menu Users = login, passwords and restrictions ATM Mgmt PVC = used for in-band management for the SCP and or endpoint routers N/A IP Port = IP address associated to the management port selection IP Security = access list IP Routing = defines what networks the SCP will respond to and the next hop router address SNMP = community names and trap managers



Users



Users Privilege Level – there are four access levels Superuser (everything), Provisioning (no management access), Maintenance (no configuration), Retrieve (view only)



ATM Management PVC



ATM Management PVC This screen displays the internal IP address assigned to the IP/SCP. This address can not be changed. It for internal use only. The SCP performs a NAT function for all SNMP commands. This address is part of Paradyne’s IP address domain.



IP Port



IP Port The SCP can have a static address or use DHCP. The two ATM connections would be used to support CPE devices that support RFC1483 routed cells. Connections for the IP/SCP to CPE devices only support RFC 1483 bridged cells. This function is not supported due to the fact that there is no CPE that can support both RFC 1483 routed and bridged cells. ENET MGMT – Is the out-of-band management port on the chassis Inband 1 – Is the 1000BaseT port on the IP/SCP card Inband 2 – Is the 10/100BaseT port on the IP/SCP card



In-Band Management SCP



In-Band Management SCP This is an example of how to associate the SCP IP address to a VLAN Configuration mode allows for support for either DHCP or manual.



IP Security



IP Security This screen allows you enter IP addresses that would be allowed to access the 8820.



IP Routing



IP Routing This screen is designed to tell the SCP as to what Address ranges it is to respond to and how to get to them.



SNMP



SNMP This screen allows the user to select the SNMP version that the SCP will respond to, the IP addresses for traps, and the two community strings for accessing the SCP.



GigE Interface



GigE Interface These are the standard GigE parameters.



10/100 Ethernet Uplink



10/100 Ethernet Uplink Rate can be set to auto or to a specific speed.



Bridge



Bridge Secure VLAN is where traffic from each user is directed to the defined Ethernet uplink. User ports can not directly communicate using the DSLAM. Switch VLAN is where each port has equal access. Uplink Tag Per Port is used in a VBN solution where a unique VLAN is required to identify each port. The VBN server can then cross reference a DSLAM port number to a room number.



ADSL2+ Line Profile Display



ADSL2+ Line Profile Display The line profile defines the link parameters. The profile name is how the link parameters are applied to the DSL ports. The line coding (Multimode, DMT, G.lite, or ANSI) are defined when a profile is assigned to a port. The reason for this is that these line profiles are used for both ADSL and Reach.



ADSL2+ Line Profile Create



ADSL2+ Line Profile Create The line parameters that are displayed are for ADSL2+. This card supports ADSL, s=1/2, ADSL-2 and ADSL2+. In order to maximize line performance you will need to review the line parameters that the ADSL CPE that you will be using supports and match them. • Max Interleave Delay – references how the error checking and correction is done (the end

result is delay) • Max additional Noise Margin – The margin level at which the CO will start to drop transmit

levels • Min Noise Margin – The minimum margin used during show time • Target Noise Margin – The margin used during training • Rate Adaptive Mode – Initial, Dynamic, Manual



ADSL2 & 2+ PSD Display



ADSL2 & ADSL2+ PSD Display These are the default setting for the ADSL2 and ADSL2+. Recommendation is that you do not change these settings.



ADSL2 & 2+ PSD Modify



ADSL2 & ADSL2+ Modify This screen allows the user to modify the PSD spectrum that the ADSL link will use.



ADSL Alarm Profile Display



ADSL Alarm Profile Display These are the the parameters that are used to generate traps



ADSL Alarm Profile Create



ADSL Alarm Profile Create Allows the user to modify what would generate a trap.



SHDSL Line Profile Create



SHDSL Line Profile Create Maximum Rate – nx64K + 16K (example for a speed equilivent to 20 DS0s would be 20x64K + 16K = 1.296 Meg Minimum Rate – never change (this is the lowest allowable rate) Mode – Annex A (US) or B (everywhere else) Remote Management – used to communicate with the CPE (ATM Management DSL) Reference Clock – System (comes from how the SCP is configured) or Local (internal clock on the 8985)



ADSL Port



ADSL Port Line Code – Multimode, DMT, G.lite or ANSI ALDSL line profile allows the user to limit the link speed.



SHDSL Port



SHDSL Port SHDSL line profile allows the user to limit the SHDSL link speed. Equipment mode allows the port to be connected on a CO SHDSL port by setting the mode to CPE mode.



ATM Profile Display



ADSL Profile Display Used to define the type of QOS for a specified connection. The voice descriptor defines a POTs card with 24 POTs ports (not currently supported by the IP/SCP).



ATM Profile Create



ATM Profile Create The traffic descriptors that are displayed will be dependent on the Cos (Class of Service) selected • PCR (Peak Cell Rate) – should be set to the link speed in cells per second • SCR (Sustained Cell Rate) – the amount of traffic that is used to define the when tagging,

policing, packet discard or shaping comes into play • CDVT (Cell Delay Variation Tolerance) – is the amount of randomness in the inter-arrival

time of cells on a given connection that is monitored at the UNI • MBS (Maximum Burst Size) – is the number of cells that can be sent together at the peak cell

rate (this is to maintain conformance with the SCR). • Tagging – marks cells that do not conform to the SCR • Traffic policing – activates the ability to tag or discard cells that do not conform to the SCR • Packet discard – drops cells that are non-compliance (ATM switches can do early packet

discarding. This allows the switch to discard all of the cells associated together to be dropped)

• Shaping – allows for the buffering of traffic to maintain SCR

Triple Play (Voice, Video and Internet) There are a number of requirements before the triple play solution will operate. Must use a layer 2 switch on the uplink that supports 802.1Q tagging (Cisco’s term for this is 802.1Q trunking). Prioritization of user traffic by 802.1p is required from the source of the user traffic to the uplink on the IP/SCP. The IP/SCP will then use the internal prioritization queues to replicate the prioritization to the subscriber. The IP/SCP cannot be set to Uplink Tagging. Initial testing should be done with the IP/SCP set to switch to simplify testing and troubleshooting. Must have an Ethernet Layer 2 switch ADSL CPE that supports port VLANs (VCC to a unique Ethernet port). Comtrend makes 4-port units that do this. We are working with ASUS to make a similar unit. The following are the steps that you will need to do to configure the IP/SCP for this application:

1. Set the Bridge mode to Switch or Secure VLAN 2. Modify all ADSL ports to fast mode or the lowest setting for interleaved mode

(required for Voice). The software in the IP/SCP has changed in regards to s=1/2. If older code fast, if newer code interleaved = 1.

3. Enable IGMP Snooping on all ports. If the multicast server is not directly attached to the same switch as the IP/SCP then enable Proxy Query. Create a VPI/VCI connection for responding to IGMP queries.

4. Create 3 New VLANs (use the ATM connection numbers to prioritize traffic). Assign all DSL (8 voice, 4 video and 2 internet) ports as untagged members and the Ethernet uplink as the tagged member.

5. Create the three DSL connections for all ports: a. Under DSL Configuration select 8 for Connection (priority) b. Enter the VPI/VCI to be used for Voice (8 is the highest priority

connection). c. Enter the VLAN number that corresponds to application for PVID d. Select 802.1p for Queue Method. e. Perform this same function for video and internet connections (4 for video

and 2 for internet) VLANs and tagging can also be used to create private connections between DSL ports. Modifying a selected DSL port in the VLAN table and assigning the same VLAN to both DSL ports is how you do this.



VLAN Configuration



VLAN Configuration This screen allows the user to create VLANs either 802.1Q or port VLANs



VLAN DSL Port Assignments



Alarms and Status This screen allows the user to assign VLAN IDs to ports on a per card basis This example shows that the Ethernet port 2 (10/100BaseT) is being used as the uplink and that the IP/SCP will accept in-bound tags and strip them prior to sending them to the DSL port. The IP/SCP can also support sending the 802.1Q tag to the CPE. The ATM connection will be referenced in the DSL connection screen. The DSL connection ties the VLAN to the ATM connection on the DSL port



Triple Play VLAN Configuration



Triple Play VLAN Configuration This screen show all of the VLAN connections that are required to support the Triple Play Solution. Note that the in-band management connection stops at the Ethernet uplink. The ATM connections are as follows VLAN 10 = ATM connection 4 VLAN 1001 = ATM connection 8 VLAN 1002 = ATM connection 7 VLAN 1003 = ATM connection 6 VLAN 1004 = ATM connection 5



DSL Connections



DSL Connections DCL connections are only built on cards that are installed. The default connections use VLAN 1 on the uplink and 0/35 on all of the ports. There are multiple levels of prioritization. Connection Prioritization or Ethernet 802.1p Connection Prioritization assumes that the CPE can support ATM VPI/VCI connections to Ethernet port VLANs Ethernet 802.1p assumes that the CPE supports 802.1p prioritization Note: Use one or the other form of prioritization



Triple Play DSL Connections



Triple Play DSL Connections This display show how all of the Triple Play connections are made. 8 = Voice – VLAN 1001 7 = Multicast Video – VLAN 1002 6 = VOD – VLAN 1003 5 = Internet – VLAN 1004



Multicast Common Parameters



Multicast Common Parameters Snooping – gives the IP/SCP the ability to support multicast video through IGMP version 2 support IGMP Proxy – is used when the device that performs IGMP polling is not directly attached to the IP/SCP



Multicast Port Parameters



Multicast Port Parameters This screen allows the IP/SCP to support channel changing This connection must get combined at the Ethernet port of the CPE. The IP/SCP combines this connection to the VLAN that supports multicast video
