ES (sec) The number of Error Seconds encountered by an ADSL interface, within any given 15 Minute or 1 day performance data collection period.
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.
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.

Add Ethernet Interface NCT480 IP-DSLAM supports two Ethernet interfaces and one management port (Ethernet port-3). The IP address is only for management purpose and each Ethernet interface can be applied with its IP address. Figure 4-13 Add Ethernet Interface Dialog Network type ‘downlink’ is for system stacking. Ethernet ports that are not used for DSLAM system management purpose do not need to be assigned with an IP address.
SNMP Host The SNMP Host configuration dialog allows you to manage the Host IP and corresponded SNMP community. Figure 4-14 SNMP Host Configuration Dialog Click ‘Add’ button to create a new SNMP Host IP address. The Host IP is the device (PC) IP address allowed to manage the IP-DSLAM via AMS (Advanced Management Service). It is recommended to limit the number of host device. Figure 4-15 Add Host IP Address Dialog Table 4-11 describes fields in the Add Host IP Address Dialog.
SNMP Community The SNMP community configuration dialog allows you to manage the SNMP community access privilege. The Simple Network Management Protocol (SNMP) is an application layer protocol that facilitates the exchange of management information between network devices. It is part of the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol suite. SNMP enables network administrators to manage network performance, find and solve network problems, and plan for network growth.
Alarm I/O Control The alarm I/O control allows you to define the alarm input and output. Please see “System Installation Guide” for the definition. Once the normal status of input signal is different from the current status, the NCT480 will launch an “abnormal status” alarm of the specified output to terminal or administrator. Figure 4‑18 Alarm I/O Control Dialog Item Description Index 1~4 This indicates the location of relay input ports (1 ~ 4).
Chapter 5 Access Control The access control functionalities allow system administrator to build packet filter and access control list.

Chapter 6 Protocol Menu Protocol menu contains setting for VLAN, IGMP, DHCP/PPPoE relay configuration and Rapid Spanning Tree Protocol. This chapter contains the following sections: • VLAN Port • Trunk VLAN Setting • IGMP Snooping • DHCP & PPPoE Relay • Spanning Tree Protocol • Rapid Spanning Tree Protocol VLAN Port The VLAN port management allows you to control the accept frame type and ingress filtering status of port interface.
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.
Add Trunk VLAN Figure 6-3 Add Trunk VLAN Dialog Item Description VLAN ID The VLAN identifier assigned to a specific VLAN. VLAN 1 is the default VLAN Valid values: 0~4095. [0 is reserved for priority tag, 4095 is reserved] Number of VLAN This indicate the VLAN ID increment number. Tagged/Untagged This setting determines a specific port to receive tagged or untagged frame. Table 6-2 Configuring VLAN Port Member YML856 Rev3 �������������������������� NCT480 IP DSLAM User Guide www.netcomm.com.
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.
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.
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.
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.
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.
Rapid Spanning Tree Protocol Rapid Spanning Tree Protocol (RSTP) is an evolution of the Spanning Tree Protocol (802.1D standard) and provides for faster spanning tree convergence after a topology change. Figure 6-8 Rapid Spanning Tree Protocol Setting Dialog Item Description DSLAM STP status Spanning Tree Protocol to be enabled on the Bridge or not. Ethernet Port STP status This specifies the STP status of Gigabit Ethernet interface. Press the ‘Apply’ button to confirm the setting.
Item Description Hello Time The value that all bridges use for HelloTime when this bridge is acting as the root. Forward Delay The value that all bridges use for Forward Delay when this bridge is acting as the root. Hold Time This time value determines the interval length during which no more than two Configuration bridge PDUs shall be transmitted by this node, in units of seconds.
Chapter 7 Diagnostic Menu The diagnostic menu provides test function from ADSL physical layer to ATM layer. This chapter contains the following sections: • DSL Bin Information • ATM OAM Test • ADSL2 DELT Test DSL Bin Information The allocation table shows both upstream and downstream bin bits and bin SNR status. Figure 7-1 DSL Bin Information Dialog Table 7-1 describes the bin allocation tap items.
ATM OAM Test The ATM OAM test generates the ATM F5 loop-back to diagnose the ADSL port interface. Operation Administration and Maintenance (OA&M) - OA&M is defined for supervision, testing, and performance monitoring.
ADSL2 DELT Test DELT is primarily used for reactive tests on a loop after a CPE has been deployed, either to help troubleshoot a line or to capture a baseline of loop characteristics at the time of installation. DELT can determine the ADSL2+ data rate (up/down), loop attenuation (up/down), SNR (up/down), and noise (up/down). Figure 7-3 ADSL2 DELT Run & Report Dialog Item Description Port selection menu Please select a port to perform DELT.
