    PART I QUICK START: INTRODUCTION & INSTALLATION The NCT-1000 & NCT-1020 are IP DSLAMs designed for MTU/MDU/MHU applications. They provide data, voice, and video services over existing copper telephone wires. Carriers and service providers can utilize the NCT-1000/NCT-1020 to offer high-speed Internet access to tenants of high-rise buildings without rewiring the building.

    Applications The NCT-1000/1020 IP DSLAMs support ADSL/SHDSL interfaces. Via the Ethernet WAN port, the NCT-1000/ 1020 IP DSLAMs can be connected to a TDM or an IP network through a router or a switch. Besides IGMP snooping for multi-cast video service, the NCT-1000/1020 IP DSLAMs also supply 802.1p Priority Queuing for the purpose of QoS (Quality of Service).

    IGMP (Internet Group Membership Protocol) is a protocol used by IP hosts to report their multicast group memberships to any immediately neighboring multicast routers. Enabling IGMP snooping allows the ports to detect IGMP queries and report packets and manage IP multicast traffic through the IP DSLAM to avoid traffic flooding.

  • Page 50 Tagged VLAN (up to 600 groups)Tagged-based VLAN is an IEEE 802.1Q specification standard. Therefore, it is possible to create a VLAN across devices from different IP DSLAM venders. IEEE 802.1Q VLAN uses a technique to insert a “tag” into the Ethernet packets. Tag contains a VLAN Identifier (VID) that indicates the VLAN numbers.
  • Page 51 Outgoing Packets for tag-based VLAN There are three types of outgoing Tag-based VLAN packets. In a VLAN entry, white means the port is not joined to any group. Yellow means the port is set to Egress Untagged. Green means the port is joined to Egress Tagged.

  • Page 52: Tag-Based Vlan

    Tag-based VLAN In the application below, there are four ADSL ports (node). A node can exist among different VLAN groups. For example, S2 in the following diagram belongs to both Group 1 and Group 2. Others nodes’ VLAN type depends on their field application, which can be Egress-Tagged and Egress-Untagged. Select Tag-Based from the VLAN Mode field.

  • Page 54 STEP 5: On the right side of the screen, for Egress Untagged port, single click the port (yellow), and for the Egress Tagged port, double click it (green). In this case, Port 1 is Egress Untagged, so click it once, and port 2 is Egress Tagged, so click it twice. When the set up is complete, click Set to apply.
  • Page 55 STEP 7: In this case, Port 2 and Port 3 are Egress tagged, so click it twice, and port 4 is Egress un- tagged, so click it once. When the set up is complete, click Set to apply. STEP 8: The setup is complete.
  • Page 56 5.1.4 VLAN PVID The VLAN PVID displays the tag-based VLAN. In a tagged VLAN application, if untagged packets are received, they will be forwarded by mapping the port VID number. The VID number is configured on the VLAN PVID tab. If the VID number is not on the VID entry list, the packets will be dropped.
