NCT480 IP DSLAM User Guide YML856 Rev3 16 www.netcomm.com.au

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) is a transfer of electrostatic charge between bodies of different electrostatic potentials, such as an operator and a piece of electrical equipment. It occurs when electronic components are improperly handled, and it can damage equipment and impair electrical circuitry. Electrostatic discharge is more likely to occur with the combination of synthetic ﬁbers and dry atmosphere.

Use an antistatic strap during removing and replacing NCT480 units.

Always use an ESD ankle or wrist strap and ensure that it makes good skin contact.

To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively.

Do not touch any exposed contact pins or connector shells of interface ports that do not have a cable attached. If cables are connected at one end only, do not touch the exposed pins at the unconnected end of the cable.

This equipment is intended for use in residential and commercial environments only.

Periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohms (Mohms).

To ensure stability of rack, you must install your NCT480 system from the bottom to the top of the rack. Before you install any of the chassis, measure the total rack space required to install your system. The required rack space depends on the number of NCT480 box chassis that you plan to use.

The NCT480 is 1.96inches (1U) in height and 10.2 inches (26 cm) in depth.

Install the NCT480 Box Chassis

Complete the following steps to install the NCT480 box chassis.

Two people are required to lift the box. Grasp the box underneath the lower edge and lift with both hands. To prevent injury, keep your back straight and lift with your legs, not your back.

Item Description

Drop if Forwarding Table Full

Status of full Bridging Status

This speciﬁes if the frame for which learning could not be done because of forwarding table limit being reached, is to be dropped. If this is enabled, the frame for which learning could not be done because of limit exceeded shall be dropped, else forwarded based on bridge forwarding logic. This being enabled shall reduce ﬂooding, as when a response to such a frame from which learning could not be done shall come the frame shall be ﬂooded, as the entry for that unicast address, shall not be found in forwarding table.

This speciﬁes the current state of full bridging on the bridge. The bridge can be set to residential bridging, restricted full bridging or unrestricted full bridging.

* Residential bridging, all packets from a CPE side port are sent to Net side port (Uplink ports) without doing a lookup in the forwarding table.

* Restricted bridging, there is a lookup and a packet coming from a CPE port destined for another CPE port is dropped. Hence, CPE-CPE switching is not permitted.

* Unrestricted bridging, all trafﬁc is forwarded based on lookup.

Power Management Mode

The power management allows you to furnish the efﬁciency of ADSL power output.

First-generation ADSL transceivers operate in full-power mode (L0) day and night, even when not in use. To address these concerns, the ADSL2 standard brings in two power management modes that help to reduce overall power consumption while maintaining ADSL’s “always-on” functionality for the user. These modes are the L2 and L3 power modes.

The L2 low-power mode enables statistical powers savings at the ADSL transceiver unit in the central ofﬁce (ATU-C) by rapidly entering and exiting low power mode based on Internet trafﬁc running over the ADSL connection. When large ﬁles are being downloaded, ADSL2 operates in full power mode (called “L0” power mode) in order to maximize the download speed. When Internet trafﬁc decreases, such as when a user is reading a long text page, ADSL2 systems can transition into L2 low power mode, in which the data rate is signiﬁcantly decreased and overall power consumption is reduced. While in L2, the ADSL2 system can instantly re-enter L0 and increase to the maximum data rate as soon the user initiates a ﬁle download. The L2 entry/exit mechanisms and resulting data rate adaptations are accomplished without any service interruption or even a single bit error, and as such, are not noticed by the user.

The L3 power modem on the other hand, enables overall power savings at both the ATU-C and the remote ADSL transceiver unit (ATU-R) by entering into sleep mode when the connection is not being used for extended periods of time. L3 is a sleep mode where trafﬁc cannot be communicated over the ADSL connection when the user is not online. When the user returns to go on-line the ADSL transceivers require at least 2 to 3 seconds to re-initialize and to enter into steady-state communication mode.

PVC Setting

The PVC Management dialog has the ability to conﬁgure the ATM PVC on ADSL port interface.

ATM (Asynchronous Transfer Mode) is more efﬁcient than synchronous technologies like time-division multiplexing (TDM). With TDM, each station or users is pre-assigned some time slots, and no other station can send in that time slot. With ATM being asynchronous in nature, time slots are available on demand.

ATM supports integrated voice, data, and video communications. In ATM the information to be transmitted in divided into short 53 byte packets or cells, which have a 5 byte header. The reason for such a short cell length is that ATM must deliver real time service at low bit rates and thus it minimizes packetization delay. ATM networks are connection oriented with virtual channels and virtual paths. The virtual channel carries one connection while a virtual path may carry a group of virtual channels. This ensures that cell sequence is maintained throughout the network. The virtual channel is identiﬁed by the Virtual Channel Identiﬁer, (VCI), and the virtual path is identiﬁed by the Virtual Path Identiﬁer, (VPI). Both the VCI and VPI may change within the network and they are stored in the header of the cell.

AAL (ATM Adaptation Layer) makes the ATM layer services more adaptable to speciﬁc services. The speciﬁc services may include user services, control services and management services. The AAL is the layer above the ATM layer and it is responsible for converting the information from the higher layers into 48 byte lengths so that the ATM layer can add the 5 byte header to make the 53 byte cell. The two main functions of this AAL are to provide functions needed to support applications and to break up information into units that will ﬁt into cells. There are ﬁve AAL layers and each layers is loosely associated with the class of trafﬁc to be carried. AAL1 is designed to support constant bit rate, connection oriented, and synchronous trafﬁc such as uncompressed video transmission. AAL2 is never completed, but it was envisioned to be assigned for variable bit rate, connection-oriented, synchronous trafﬁc. AAL3/4 supports variable bit rate, connection oriented, and asynchronous trafﬁc or connectionless packet data. AAL5 is the primary AAL for data and supports both connection oriented and connectionless data.

Be sure to use the encapsulation method required by the ATU-R. The NCT480 IPDSLAM supports the following methods.

EOA: Ethernet over ATM. EoA beneﬁts from SONET/SDH protection but has been criticized for being expensive and having scalability issues. EoA offers smooth roll out of Ethernet-based services in existing Asynchronous Transfer Mode ATM network and optimizes the use of spare capacity in the ATM network.

IPOA: Some CPE devices have IPoA interfaces towards the WAN side. These interfaces need to be supported and retained by the service providers. Also DSLAMs are moving from ATM to Packet mode and hence support for these interfaces on the CPE side becomes essential. In order to provide this ﬂexibility in the route mode ﬁrmware release R2.0, RFC 2684 Routed (IPoA) interfaces along with the existing RFC 2684 Bridged Ethernet interfaces shall be supported.

PPPOA: PPPoA stands for Point to Point Protocol over ATM Adaptation Layer5 (AAL5). A PPPoA connection functions like a dial-up Internet connection. The NCT480 IP-DSLAM encapsulates the PPP session based on RFC1483 and sends it through an ATM PVC (Permanent Virtual Circuit) to the CPEs. Please refer to RFC2364 for more information on PPPoA.

Using all this information, an ARP request for the IP address speciﬁed in the gateway IP address of the default route. BRAS shall respond the ARP request from the NET side. Also due to source MAC address based learning, an entry in the MAC address-forwarding table will get created, which is required for the upstream forwarding. Hence, the upstream trafﬁc can ﬂow.

MAC address proﬁle is a generic way for assigning MAC addresses to interfaces. A MAC address can be associated with a proﬁle and that proﬁle can be attached to the interface.

Currently a maximum of 48 proﬁles are supported in the system.

Trunk VLAN Setting

The trunk VLAN setting dialog list the existing trunk VLAN and its conﬁguration.

A VLAN allows a physical network to be divided into several logical networks. A device can belong to more than one VLAN group. Devices that are not in the same VLAN groups can not talk to each other. VLAN can provide isolation and security to users and increase performance by limiting broadcast domain. VLAN tag can be added to the MAC header to identify the VLAN membership of a frame across bridges. A tagged frame is four bytes longer than an untagged frame. Each port of NCT480 is capable of passing tagged or untagged frames.

VLAN Mode Setting

With the Ethernet becoming cheaper and more popular, the Ethernet networks are expanding to cover metros. This is leading to deployment of MEN (Metropolitan Ethernet network). The existing support for VLAN as standardized in IEEE 802.1Q is not able to scale to MEN deployment, because of limited 4095 VLANs and hence the requirement for VLAN Stacking.

VLAN Stacking, also known as Q in Q, is the mechanism where one VLAN (Virtual Local Area Network) may be encapsulated within another VLAN. This allows a carrier to partition the network among several national ISPs, while allowing each ISP to still utilize VLANs to their full extent. It is very important to logically separate all trafﬁc between ISPs – for security, for offering different levels of service to prospective ISP customers and the ability to utilize full VLAN space.

In a typical network scenario Columbia is on edge of provider network (Ethernet Aggregation Network), the location of DSLAM as shown in Figure 6-4 depicting Network Scenario.

Figure 6-4 Network Scenario

NCT480 IP DSLAM User Guide YML856 Rev3 82 www.netcomm.com.au

With VLAN stacking, if one ISP provisioned an end user into “VLAN 1”, and another ISP provisioned one of their end users into “VLAN 1”, the two end users would not receive each other’s trafﬁc.

Figure 6-5 VLAN Mode Setting Dialog

Item Description

VLAN mode

Single VLAN: The single VLAN Mode conﬁrms to the normal 802.1Q VLAN support and the system will continue to work as is in the current model without VLAN stacking.

Double VLAN: VLAN used in VLAN aware networks based on 802.1Q bridging is called C-VLAN (Customer-VLAN), and can be uniquely identiﬁed by a C-VLAN tag VLAN that encapsulates Customer trafﬁc in Provider network is called S-VLAN or Service VLAN and is identiﬁed by an S-VLAN ID, used as second VLAN tag. In this mode the features can be used to meet custom VLAN stacking requirements.

Press the ‘Apply’ button to conﬁrm the setting.

IGMP Snooping

The IGMP Snooping allows you to view and change the IGMP Snooping administrate status.

IP trafﬁc can be transmitted in one of either three ways: unicast (one sender to one receiver), broadcast (one sender to all members on the network) or multicast (one sender to a group of hosts). IGMP is a session-layer (layer-3) protocol used to establish membership in a multicast group.

Multicast addresses are Class D IP address, from 224.0.0.0 to 239.255.255.255. These addresses are also referred to as Group Destination Address (GDA). Each GDA address is associated with one MAC address. The GDA MAC address is constructed by joining 01:00:5E and the last 23 bits of the GDA multicast IP address in Hex. For example, GDA 224.1.1.1 corresponds to MAC address 01:00:5E:01:01:01

A layer-2 switch supported IGMP snooping can passively snoop on IGMP Query, Report and Leave packets transferred between Routers/Switches and hosts to learn the IP Multicast group membership. It snoops IGMP packets passing through it, picks out the group registration information, and conﬁgures multicasting accordingly.

IGMP Snooping Leave message processing mode for the port.

If the mode is set to ‘Normal’, the Leave message is forwarded to the Querier and then based on the Query received from Querier the Leave processing is triggered.

If the mode is set to ‘Fast’, the port is immediately deleted from that multicast group on Leave message reception and then the Leave message is forwarded. The mode should be set to ‘Fast’ for a port only if there is one host behind the port. This is because if there are multiple hosts behind the port then it will lead to trafﬁc disruption for other hosts who might still be listening to that multicast group.

If mode is set to ‘FastNormal’, the Leave message is forwarded and the Leave processing is triggered immediately without waiting for any trigger from the Querier. ‘FastNormal’ mode thus saves the delay (equal to the time taken for Leave message to reach router and Querier processing time for it and the time taken for Query to reach IGMP Snoop module) in Leave processing.

NCT480 IP DSLAM User Guide YML856 Rev3 84 www.netcomm.com.au

DHCP & PPPoE Relay

The DHCP Relay conﬁguration provides DHCP Relay Option 82 function.

DHCP allows individual computers on an IP network to extract their conﬁgurations from DHCP server. The overall purpose of this is to reduce the work necessary to administer a large IP network. The most signiﬁcant piece of information distributed in this manner is the IP address. Information can be added into client TCP/IP conﬁguration requests that IP-DSLAM relays to a DHCP server. This helps provide authentication about the source of the request. Please refer to RFC 3046 for further details.

The PPPoE Relay feature enables an L2TP access concentrator (LAC) to relay active discovery and service selection functionality for PPP over Ethernet (PPPoE), over a Layer 2 Tunneling Protocol (L2TP) control channel, to an L2TP network server (LNS) or tunnel switch (multihop node). The relay functionality of this feature allows the LNS or tunnel switch to advertise the services it offers to the client, thereby providing endto-end control of services between the LNS and a PPPoE client.

Spanning Tree Protocol

The spanning tree protocol allows you to conﬁgure the STP parameters on network Ethernet interface.

Spanning-Tree Protocol is a link management protocol that provides path redundancy while preventing undesirable loops in the network. For an Ethernet network to function properly, only one active path can exist between two stations. Multiple active paths between stations cause loops in the network. If a loop exists in the network topology, the potential exists for duplication of messages. When loops occur, some switches see stations appear on both sides of the switch. This condition confuses the forwarding algorithm and allows duplicate frames to be forwarded.

To provide path redundancy to prevent undesirable loops, Spanning-Tree Protocol deﬁnes a tree that spans all switches in an extended network. Spanning-Tree Protocol forces certain redundant data paths into a standby (blocked) state. If one network segment in the Spanning-Tree Protocol becomes unreachable, or if Spanning-Tree Protocol costs change, the spanning-tree algorithm reconﬁgures the spanning-tree topology and reestablishes the link by activating the standby path.

STP is a technology that allows bridges to communicate with each other to discover physical loops in the network. The protocol then speciﬁes an algorithm that bridges can use to create a loop-free logical topology. In other words, STP creates a tree structure of loop-free leaves and branches that spans the entire Layer 2 network.
