Management surface

DSLAM has a WEB management surface. We can find the web address, name and password in the black folder of the measurement.

In case of the laboratory no. 212 we should start the WEB browser from the PC connected to the 7. button of the console switch!!

Main menu

Basic Setting - (VLAN switch, interfaces (Ethernet, ADSL))

Advanced applications - Programming of complementary services

Switch Setup - DSLAM VLAN switch configuration

Protocol layer:(Ethernet)

VLAN switch in the DSLAM has 12 ADSL (Port 1..12) and two Ethernet (ENET1, ENET2) ports. Switch makes the direction of Ethernet packets according to MAC addresses, and direction of tagged Ethernet packets according to VLAN_IDs. Switch can make a packet order rearrangement on the basis of the VLAN priority parameter. Switch can be automatically configured with the help of two protocols in the VLAN. They are the following:

Configuration of the VLAN-switch happens in two steps:

Switch operation mode and its general parameters are the following:

IP Setup - configuration of IP address of a broadband and managing interface

(These parameters are set according to the measurement exercise, their programming is not necessary.)

Default:

Enet port setup - configuration of a broadband and managing interface

(These parameters are set according to the measurement exercise, their programming is not necessary.)

Basic Setting - xDSL Port Setup - configuration of the ADSL U (line) interface and the ATM VCs (virtual channels)

Protocol layer:(ADSL)

In this menu we can configure ports of DSLAM ADSL and the ATM virtual channels assigned to the ADSL ports. In the ADSL modem WAN setup menu connecting to the port can the other port of the ADSL connection be programmed, and to give there the data consistent with the ones located here.

Configuration of multitudinous ports with the similar characteristics in many cases we can make easier with usage of configuration profiles. Parameters of ports with the same characteristics with the same value we can edit once separatedly (profile), and we write only the identifier of the profile to the database of the port.

In the opening menu of xDSL Port Setup we can choose, which ADSL port we wish to edit. After choosing the ADSL port sets can be edited in several submenus (xDSL Port Setup, VC Setup, PPVC Setup). Besides, we have a possibility to a database manipulation in the opening menu (copy-paste functions).

Note: Provider products also SHDSL modems in this system, that is from the name xDSL derives.

Submenus of the xDSL Port Setup:

  • xDSL port setup (after selection of a port)

  • VC ( Virtual Channels or Permanent Virtual Circuits or PVCs ) setup

    Protocol layer:(ATM)

    We can order eight VCs to every DSL port. We can use VCs for different services, or for realization of levels of a service. For the realization we can order PVIDs to VCs, and IEEE 802.1p priority parameters to them. These data can be ordered automatically to every received untagged frame.

  • PPVC (Priority based Permanent Virtual Circuit) setup

    Protocol layer:(ATM)

    PPVC (Priority-based permanent VC) service gives a possibility to order different priorities to PVCs ordered to the same VLAN. PVCs can use 8 priority queues (levels) in DSLAM.

    In case of super channel this service cannot be used.

    Entering to the menu, the upper part of the window serves for giving of the parameters of PPVCs, and the lower part of the window we can see the list of the realized PPVCs. Editable parameters:

    We can edit elements of PPVC in the list of realized PPVCs, clicking to one of the elements of Members column:

    xDSL Profile Setup

    In this menu we can edit profiles used for configuration of ADSL ports.

    In the opening menu of xDSL Port Setup we can choose, which ADSL port we wish to edit. After choosing the ADSL port sets can be edited in several submenus (xDSL Port Setup, VC Setup, PPVC Setup).

    Entering to the menu, the upper part of the window serves for giving of the parameters of profile, and the lower part of the window we can see the list of the realized profiles. Editable parameters:

    xDSL Line Data

    Parameters can be seen in this menu are measuring results of ADSL modems relating to ADSLlayer:

    VLAN - Virtual Local Area Network

    With the help of this function we can divide a physical LAN to several virtual LANs. It is a possibility to separate users, which can happen practically on the ports of VLAN switch.
