Configuring of subscriber access

1. The purpose of the work

Learning of capabilities of subscribers’ interfaces management. Creation of user accounts, linking them to the physical access, testing of created connections.

2. Key positions

2.1 The management of user accounts. All the data about subscriber numbers can be written, changed and deleted in the window Subscriber. Administration of subscriber data is performed by the menu CMG – Subscriber – Subscriber. Every subscriber record has following data:

• Node;

• Directory No. (subscriber number);

• Basic Service (subscriber category);

• Module, in which it’s located access, connected to the Directory No. (if the number is free, the number of the module will be 0);

• Port, to access of which Directory No. is connected;

• Feature Set – the set of additional services;

• Centrex-group, in which the subscriber is included;

• Traffic Meas. Group, in which the subscriber is included (this data is used in the application PMG).

• Redundant Access (backup connection).

During the creation of new subscriber numbers this data can be written for one or several subscribers simultaneously, what is defined by the values of parameters Start Directory Number and End Directory Number, notably:

• If data is entered for one subscriber, the values of both parameters are the same;

• If data is entered for several subscribers simultaneously, the range of subscriber numbers is specified by values of these two parameters.

The parameter by Mode defines increment when the data is entered for several subscribers simultaneously. If the step is 1, all the numbers in the range will be entered. If the step is 10, only every 10^th number from the specified range will be entered. During the creation of a new subscriber number it should be obligatory included in the range of numbers, described in the numbering plan.

Also for the new subscriber such parameters as Basic Service and Feature Set should be specified.

The sets of additional services are formed in the window Feature Set, which is opened by the command Subscriber – Feature Set. Every set of services can be changed later according to real needs. It can be performed in the window Subscriber by the command Update.

In addition by the checking the checkbox (View report) the report about new entered data after completing the procedure can be shown. The output of the report is shown in the application Notepad.

New subscribers are written directly to the database and for their search in the table an operator uses command Query and Retrieve.

By means of the command Update such things can be done:

• To change the set of additional services for every subscriber – Feature Set;

• To grant and cancel the right of using of additional services (the right is granted by the checkbox in the column Authorization);

• To activate and deactivate granted additional services (the service is activated by the checkbox in the column Activity);

2.2 Binding subscriber number – port. The subscriber access defines the characteristics of the physical subscriber port. The set of subscriber accesses depend on hardware and is defined during the administration of subscriber cards.

The window Analog Access is opened by the command Access – Analog – Global. There you can change characteristics of every single access and add the data of new analog accesses.

About separate accesses such data is shown:

• Node;

• Module, where the port is located;

• Port – the physical port for which we specify characteristics;

• Default DN – the subscriber number, connected to this access (this parameter has the value -1, if no number is connected to this access);

• DTMF Auth. – the way of dialing;

• Variant – the variant of data about the access.

Data can be added for one access or for several ones simultaneously, what is defined by the values of parameters Start Port and End Port (the way of input is the same as Insert – Subscriber).

By means of this command the window Analog Access – Update is opened, where you can change the type of dialing (DTMF Authorization) and the variant of data (Variant).

The window Numbering is opened by the command Access – Numbering, Simultaneously near the name of the window the number and the type of the node are also shown. This window is intended for the administration of the numbering of accesses. The administration of the numbering of accesses means the connection of subscriber numbers to the ports and disconnection. For every digital and analog access several subscriber numbers can be assigned.

The window Numbering consists of 3 fields:

• Access, which is used for view and output of data about accesses, for granting rights to the service MSN and for the creation and deleting the connection of the certain access with the subscriber number or several numbers;

• Subscriber, which is used for view and output of data about subscriber numbers and for creation and deleting connections with chosen accesses;

• Common field intended for the connection of accesses with subscriber numbers.

During the output of data on demand of the user (commands Query and Retrieve) such options can also be chosen:

• All, when the output of data about all ports and subscriber numbers is requested.

• Linked, for the output of connected ports or subscriber numbers;

• Unlinked, for output of available free ports and subscriber numbers.

To define the correspondence of an user account to an available port it is necessary to perform sampling with parameter Unlinked in the window CMG – Access – Numbering for tables Access and Subscriber, choose the necessary number and port and link them by means of the button Link MASN.
