Figure1-1. Application scenario of IVD
In this application scenario, IVD connects to IP backbone network through Gigabit Ethernet interfaces to minimize the investment of service provider. System provider can easily install and scale the network with the same framework. IVD provides mini or middle scale system architecture to system provider a very cost effective solution and deploy VoIP service without spending extra line installing fee.
As IVD supports high upstream and downstream bit-rates performance, therefore, IVD is being deployed primarily for residential customer for IPTV application or high speed Internet service or business customers to replace expensive T1/E1 leased line and use convenient VoIP application.
IVD is not only equipped with a console port being used for local management, but also provided excellent capabilities of SNMP, Telnet for remote management. In particular, IVD can be easily configured by EMS. The EMS system covers topology, configuration, deployment, security, alarm management and backup storage. Moreover, with the solution of port-based and tag-based VLAN, IVD can isolate traffic between different users and provide improved security.
The compact design of IVD is for 24-port ADSL 2/+ with built-in POTS splitters connected to ADSL modems and 24-port FXS VoIP.

The POTS splitter should be connected to MDF on building or CO side in Figure 1-10. An MDF is usually place in the building’s telephony room or on central office room. It can terminate the outside telephone line into the building. Most MDF has surge protection feature to protect the equipment from damage. In general, The LINE and PHONE interface all connect to MDF and then to outside connection.
Figure 1-10. MDF connection architecture
1.5.2 Centric Patch Panel Connection
The IVD can provide ADSL and voice services over the same telephone wiring. It also has built in splitters internally that can save space and simplify installation.
If the application is using on building environment, the CPP (Centric Patch Panel) is preferred. The purpose of CPP module is to transfer RJ-21 jack in IVD to RJ-11 connector. The CPP front panels are shown in Figure 1-11. It is usually installed between end-user’s equipment and telephone company in a basement or telephone room. The CPP is the point of termination for the outside telephone company lines coming into a building and the telephone lines in the building.

1.6.4 Optical Giga Ethernet Interface as Trunk Interface with SC Connector
The trunk interface is made with the SC connector, which is available in two types:
Gigabits Ethernet optical long haul LX single mode interface. Gigabits Ethernet optical short haul SX multimode interface.
For each type of optical transceiver, they should connect with corresponding optical fiber with proper mode. Incorrect fiber mode may affect link distance or even link fail. Fiber for long haul LX: Single-mode (SM), 9/125 micron. Fiber for short haul SX: Multi-mode (MM), 50/125 or 62.5/125-micron.
The two types of interface are visually and functionally similar. Installation procedures are the same. This dual port has both connectors on transmit (upstream) and a receiving (downstream) as shown in Figure 1-
18. There are warnings for the optical fiber connection.
Warning
The laser energy of the fiber optic communication channels in the single-mode will be harmful when
operate, especially to the eyes. During normal operation with cable connection, this energy is confined to the cable with no danger present.
Because the laser radiation is invisible and may be emitted from the aperture of the port before
connect the cable or protective cap, please avoid exposure to laser radiation and also do not fix the gaze to open apertures.
The following precautions are to avoid injury when connecting or disconnecting optical channel. Always connecting optical cables before power on. Always keep the protective cap on the optic connector. Never stare into an optical cable or connector when the connector is not in use.
Connect the fiber channel using the following steps:
Step 1 Read and understand the previous warnings and alarm. Step 2 Remove the protective caps from the fiber optic connector and from the external data cable. Step 3 Attach the external cable to the recessed connector on the faceplate as shown on Figure 1-17. Step 4 To avoid exposure to laser radiation by plug the protective cap. Store protective cap on the clear
place to use when no optical fiber connection or on stock.

Ethernet Bridging
There are three features supported for bridge function.
IEEE 802.1d STD transparent bridging Up to 4000 MAC entries address table Port-based VLAN IEEE 802.3 ad standard.
Supports oversized Ethernet frames up to 1526 byte.
IEEE 802.1Q Tagged VLANand Double-tagged VLAN capabilities conform to IEEE 802.1ad Standard
IVD uses the IEEE 802.1Q Tagged and double Tagged VLAN; users can allow this device to deliver tagged/untagged frames in these ports. The IVD supports up to 512 VLAN groups and can be applied up to 4094 VLAN identifications.
VLAN Feature
The DSLAM is able to attach VLAN tag (S-Tag) to untagged frames, received on user ports at the
upstream direction.
The DSLAM is able to attach a second VLAN tag (S-Tag) to tagged frames (C-Tag) received on
user ports at the upstream direction.
The DSLAM is able to attach two VLAN tags (S-Tag, C-Tag) to untagged frames, received on user
ports at the upstream direction.
The DSLAM is able to remove VLAN Tag identification (S-Tag) from frames received from the
aggregation the DSLAM". (i.e. downstream direction) before sending them on user ports.
The DSLAM is able to remove VLAN Tag identification from frames received from the aggregation
network (i.e. downstream direction) before sending them on user ports. The options for. The options for removal are both S-Tag and C-Tag.
The Ethertype field for the 802.1ad tagging, i.e. S-Tags, is configurable.  The DSLAM supports two types of tagged ports:
VLAN-transparent port
Non VLAN transparent port VLAN allocation and forwarding mechanisms
IVD conforms to 1:1 VLAN forwarding defined in WT101 of DSL Forum.  IVD is able to disable address learning for 1:1 VLANs.  IVD conforms to N:1 VLAN forwarding defined in WT101 of DSL Forum.
IEEE 802.1p Priority
IVD supports IEEE 802.1p at VLAN level to assign priority levels to all individual ports. Users can set different quality of service for individual application. For example, voice and video services can set high priority and Internet data service will be lower priority.
Support 4 queues for per ATM port. Support 8 queues for per physical Ethernet port.
MAC Address (Media Access Control) Filter
IVD can let users use the MAC filter for incoming frames based on MAC (Media Access Control) addresses that specified by users. Users can enable/disable this function on specific port.
Access Control List per port is up to 8 entries. If port receives a packet which source MAC address
is met with one of the 8 entries, this packet can be forwarded to destination port.
Access Control List per device is up to 1024 entries. If port receives a packet which source MAC
address is met with one of these entries, this packet would not be forwarded to destination port. The high priority of ACL rules is the allowing rule checking for per port.
MAC Address (Media Access Control) Count Filter
IVD supports users to limit the number of MAC addresses that may be dynamically learned or statically configured on a port. Users can enable/disable this function on individual ports. The global static learning table has up to 512 entries. Each entry can be set to a specific port. In dynamic learning mode, there are 16 MAC address entries in DSL port and 256 entries in Ethernet uplink port.
Page 41
Version: 1.5

Multi-Protocol Encapsulation
IVD supports bridge and routed of multi-protocol encapsulation over ATM adaptation Layer 5 based on RFC2684.
Management
IVD supports some management method as listed below.
Remote configuration backup/restore via EMS client/server. Remote firmware upgrade SNMP management Command Line Interface, it can be accessed by local Console or Telnet interface.
Multiple PVC on single port
IVD allows you to use different virtual connection also called PVC (Permanent Virtual Circuits) for different services or subscribers. Users can define up to 8 PVC connections on each DSL port for different services or levels of service, and users can assign different priority for each connection.
PVC Binding VLAN DSLAM supports binding of ATM PVCs of a given DSL port to different VLANs according to WT101 of DSL Forum, IPDSLAM supports simultaneously the following
binding multiple ATM PVCs (of same or different DSL ports) to a singe VLAN, binding multiple (m) ATM PVCs (of same or different DSL ports) to multiple (n)
VLAN where m>=n and n1. A given ATM PVC will not be bound to more than one VLAN.
IGMP Snooping
IGMP (Internet Group Management Protocol) snooping reduces multicast traffic for maximum performance. The feature is very popular for video multicast application for example IPTV service.
3.2 Quality of Service (QoS)
Quality of Service (QoS) refers to the capability of a network to provide better service to select network traffic over various technologies. The primary goal of QoS is to provide priority including dedicated bandwidth, controlled jitter and latency (required by some real-time and interactive traffic), and improved loss characteristics. Also it is important to make sure that providing priority for one or more flows does not make other flows fail. QoS technologies provide the elemental building blocks that will be used for future business applications in campus, WAN and service provider networks. This feature can be used for VoIP traffics.
3.2.1 Prioritized Bridging
IVD supports for multiple queues per port. There are different queues both on ATM and Ethernet uplink.
Four queues supported per ATM port. Eight queues supported per physical Ethernet port.
3.2.2 Scheduling Mechanisms
IVD supports multiple scheduling mechanisms.
Strict Priority Scheduling Probabilistic Priority Scheduling
Page 42
Version: 1.5
42
3.2.3 Rate Limiting
IVD supports rate-limiting function in input/output both direction.
Input Rate Limiting (IRL) on a per-AAL5 interface. Output Rate Limiting (ORL) on a per ATM-port basis Output Rate Limiting (ORL) on a per-physical Ethernet Interface basis.
One feature supports for buffer admission control triggered using IRL. Moreover, it also supports for dynamic modification of ORL on ATM and Ethernet interfaces.
3.2.4 Mapping Table
IVD supports a packet priority to traffic class mapping table supported on a per egress bridge port.
3.2.5 Multiple Mechanisms
IVD supports two multiple mechanisms as below.
Multiple mechanisms of prioritizing incoming traffic are based on a per-bridge port.
(1) Using Source Port configuration (for untagged packets) (2) Using Packet Classifier actions (3) Using priority regeneration table (mapping ingress priority to egress priority) (4) Combination of the above
Multiple mechanisms of 802.1p re-tagging of outgoing traffic is based on a per ingress bridge port.
(1) Using Source Port configuration (for untagged packets) (2) Using Classifier actions (3) Using priority regeneration table (mapping ingress priority to egress priority) (4) Combinations of the above
3.2.6 Abilities
IVD can be able to create multiple scheduling profiles, either Strict Priority or Probabilistic Priority. It also can be able to share the same profile across multiple (similar) ports.
3.3 Security
IVD supports some different methods to implement this feature in following sections.
3.3.1 Static Mac Address
IVD supports this feature to be configured with certain ports to learn MAC addresses on a semi­permanent basis. These learned entries would be treated similar to the static entries, but will not be subject to aging or overwriting. These only may be deleted explicitly by management or by making the ports, as non-static after aging will happen normally.
Page 43
Version: 1.5
43
3.3.2 FDB Conflicting Traps
IVD will transmit a trap packet to central manager when any MAC address moves from one port to another port.
3.3.3 MAC Address Tracking
IVD can be configured to track a global list of MAC addresses. When these MAC addresses move from one port to another port, a trap is generated. Whether packets from a particular bridge port should be subjected to this tracking is configurable. This may be used to prevent denial of service from certain MAC addresses.

VLAN based on:
Source address matching Group address matching
IVD is able to configure per DSL port the maximum number of simultaneous multicast channels
allowed.
IVD supports the Globally Scoped Multicast Addresses (224.0.1.0 – 238.255.255.255).  IVD supports the Limited Scoped Multicast Addresses (239.0.0.0/8).  IVD supports a mechanism to prevent a user port from becoming a multicast router port by
blocking IGMP query messages.
IVD supports mechanisms to stop user ports injecting unauthorized multicast traffic into the
aggregation network.
The DSLAM support IGMP Fast Leave.  N:1 VLANs forwarding mode is used in order allow efficient forwarding of multicast traffic. (It is to
be noted that other types of traffic (data, voice, unicast video) could be delivered via N:1 VLANs as well.)
Dedicated Multicast VLAN model is supported. (This is a model where a dedicated N:1 VLAN is
used to send some multicast groups from a multicast router / BNG to one or several access nodes, over an aggregation network. Other traffic is sent across different VLANs, where these VLANs could be 1:1 or N:1.) Integrated Multicast VLAN model is supported. (This is a model where multicast traffic is inserted into one of the N:1 VLANs that are terminated at a subscriber DSL port, or alternatively dot1q trunked to the RG. This effectively means multicast and unicast share a VLAN.)
