Start Up of the Configuration Function

Select "E" on the thumbwheel and confirm with the validation switch. When the LED1 flashes all the LEDs are lit, set the thumbwheel switch to "8" and push the validation switch. The default configuration will be copied to the fixed configuration.
In the factory line 5 of the default configuration file of the FastPAD has been configured for asynchronous use with automatic recognition of the bit rate.
The cable to be used between the terminal and the FastPAD has to be a direct cable (DTE-DCE).

When the FastPAD equipment is in service (see Management functions manual for start-up), access to the configuration function is gained via an asynchronous terminal.

Equipment Configured on Site

In this case a standard asynchronous terminal can be connected to any asynchronous configured port of the FastPAD.
The terminal can also be connected to the DIN connector on the front panel (via a special cable: see Installation Manual) but then not all functions can be accessed. Communications made via this connector are cleared automatically after about 1 hour of inactivity.

Sequence of a Configuration Session

The figure below gives the sequence of a configuration session. For the description of the different phases see the paragraphs mentioned in the figure.

Figure 2-2: Sequence of a Configuration Session

Access to the Configuration Function

The configuration function is a resident internal subscriber in each FastPAD. It is accessed via an X.25 address which conforms to the same numbering system as defined across the network.

Access

Access Method

The syntax of the access code to the configuration function is:

DNIC Z0 AB D is Nº Password (CR)

DNIC = Identification of private network
ZO = Identification of the FastPAD
AB = 99 (subscriber number for all management functions)
D = Data separator
IS Nº = 10 (The Configuration function in clear-language mode; see note 1)
PASSWORD = Exists if configured (CC is the password specified in the default configuration)
(CR) = Carriage return.

e.g. 90000099D10CC is the access code of the default configuration.

Note 1) Refer to the management functions manual for a more detailed explanation of this access code.

2) An abbreviated access code can be configured (see class 7 of the configuration). In this case, a point (.) must be typed before the abbreviated code for the link to be established.

3) Access to the configuration function through the front panel is not recommended.

Error Messages

Typing an incorrect access code results in rejection of access to the function. An error code followed by a message in clear language is then displayed on the screen (see the chapter "Network Trouble Management" of the Management Functions Manual.)

Display of the Welcome Menu of the Configurator

Typing the access code defined in the preceding paragraph causes a welcome page of the following type to be displayed.

Example:

Figure 2-3: Welcome Page

Note 1) A commands menu may be consulted whenever establishing the new configuration. Simply type H, when you are at class or recurrence level, followed by (CR).

2) Scrolling of the text on the screen of an asynchronous terminal can be stopped by sending X.OFF (CTRL/S character.)
To resume scrolling, send X.ON (CTRL/Q).

3) When the key code is not correct, type "CTRL/P", "CLR" and then the characters "CLR" to quit the configurator.

(1) Except for classes 12, 24 and 30 where the syntax is:

S/Row no./Parameter no./New value (CR)

(*) Selective reset of one or more lines takes place only if there is a modification of the connection or extension parameters in class 12 or 13 or C1 R1 before the output through F or V.

(**) The status of the configuration may be consulted at the class level by typing SS followed by (CR). The status of the configuration indicates the following information depending on its location:

In EEPROM, command SS indicates the remaining EEPROM size and the CCR marker. The CCR marker is the image of CCR (checksum) of the CONFIG RAM configuration,
In CONFIG RAM, command SS indicates the compressed size and its CCR,
In operational RAM, command SS indicates the type of starting: OP = operational; DF = default.

As an example, when command SS is used, the configurator displays the following:

Figure 2-4: Display when Command SS is Typed

In the above example, modules 0 and 2 are not present.

Access protection of certain classes

Certain recurrences or classes that contain system data may be read-and/or write-protected. Access to these classes is therefore subject to the typing of a KEY code (from l to 8 alphanumeric characters) specified in the existing configuration (see C0R0, C2R0 and C2R1 in Chapter 4 of this manual).

The display of the word "key" on the welcome page indicates that the system is waiting for a command.

This command may be:

A KEY code followed by (CR) to access all classes, even read-and/or write-protected ones. To protect its confidential character, the system does not echo this KEY code. CCLAER is the KEY code of the default configuration.

Note The commands F, V, I and SA are inhibited. When an incorrect KEY is entered, the following message is displayed: "KEY code incorrect, command not possible."

: The commands D and ISE number of line are also inhibited.

(CR) immediately, for access to only unprotected classes. See the next paragraph for a description of the read and write protection.

Choice of Type of Reset

When the KEY code is validated, the "TYPE OF SESSION, ISE OR ITO?" message is displayed to allow the operator to specify the type of reset planned at the end of the configuration session.

Total Reset

Type ITO and (CR) for a complete reset if the changes affect all lines or the overall operation of the FastPAD (classes not accessible during an ISE session, described below).

The commands F, V or SA are impossible during a ITO session.

Note A complete reset must be given after a modification on the class 32 or the parameter 90 of the class 12 of the frame relay line. A complete reset must be given after a modification on the parameters of the MLP bundle. After any modification on the virtual router, SNMP, or FP routing, the user must completely reset the system (ITO).

Selective Reset

Creation of a line: when a line is added in class 1, recurrence1 and in classes 12 and in classes 12 and 13 for the associated connection parameters.
Modification of type of line already created: when the type of line is modified in class 1, recurrence 1 and in classes 12 and 13 for the associated connection parameters.
Elimination of a configured line: when a line is no longer configured in class 1, recurrence 1.

Type ISE followed by (CR). In ISE, the classes/recurrences/parameters (general operation of FastPAD) below are not accessible for modification:

· Class 1:	Identification OF CONFIGURATION (except for recurrence 1)
· Class 2:	GENERAL PARAMETERS
· Class 3:	MANAGEMENT FUNCTIONS
· Class 4:	TABLE OF INTERNAL SUBSCRIBERS
· Class 14:	X.3 CUSTOMER PROFILE
· Class 24:	MANAGEMENT FUNCTION, SECURIZED VCs. X.29 REROUTING, COMPRESSlON

All modifications outside these classes are updating the fixed configuration's EEPROM and RAM by the command "F".

The selective reset (ISE) of one or more lines by the command "F" or "V" is only possible when the parameters to modify are parameters in class 1, recurrence 1, and classes 12 or 13.

Note We strongly advise against the modification of parameters in the classes 12, 24 or 30 during an ISE session.

· Class 12:	X.25 PARAMETERS
	Parameter 4:	Number of the 1st group of incoming logical channels
	Parameter 5:	Number of 1st incoming logical channel
	Parameter 6:	Number of groups of incoming logical channels
	Parameter 7:	Number of incoming logical channels
	Parameter 8:	Number of the 1st group of mixed logical channels
	Parameter 9:	Number of 1st mixed logical channel
	Parameter 10:	Number of groups of mixed logical channels
	Parameter 11:	Number of mixed logical channels
	Parameter 12:	Number of the 1st group of outgoing logical channels
	Parameter 13:	Number of 1st outgoing logical channel
	Parameter 14:	Number of groups of outgoing logical channels
	Parameter 15:	Number of outgoing logical channels
	Parameter 90:	Number of PVCs or cluster
	Parameter 91:	Position of first PVC or cluster
	Parameter 94:	Securized virtual secrets

Modification of these parameters is still possible when the new value is lower than the existing value.

Example:

A line reset will be executed correctly when the number of mixed LCs is changed from 20 to 10.
However, changing the number of mixed LCs from 20 to 100 could provoke a total reset of the switch.

Because the classes 8, 17 and 19 refer to each other, these classes must be reset with an ITO.

Note Section "End of Configuration Session and Reset" of this chapter explains how to quit the configurator and initiate the reset.

Access to parameters and modifications

Access Method

When the KEY code and the (CR) and the type of session have been typed, the operator may access the parameters to be modified.

The system imposes a selection among the three configuration levels:

Figure 2-5: Selection Among Three Configuration Levels

Note It is not necessary to follow the numerical order of the classes, recurrences, and parameters.

Example:

Parameter 3, recurrence 1 of class 15 may be modified before parameter 1, recurrence 8 of class 3.

Access to parameters and modifications

From the welcome page of the configurator, the parameters to be modified are reached as follows:

Figure 2-6: Modifying Parameters on the Configurator's Welcome Page

The meeting of the line is not taken into account when the modifications involve parameters other than in classes 12 and 13 linked with the line. The modifications of these parameters requires the operator to use the command: ISE line-number.

* One or more lines may be reset without parameter modification by typing:

Figure 2-7: Resetting Lines without Parameter Modification

** When the key code is not correct, whatever the session (lSE or ITO), the configuration session cannot be closed with the commands "F", "V", "SA" or "I". To quit the configuration, type "CTRL/P", "CLR". The command "CTRL/P", "CLR" cancels all the modifications entered during the session.

Figure 2-8:
Configurator Display and Operator Response

** This meaning does not apply to classes 12, 24 and 30:

*** Command usable only in classes 12, 13, 24 and 30.

Error Messages

The typing of an incorrect class, recurrence, or parameter number leads to the display of one of the following messages:

INVALID CLASS No.

INVALID RECURRENCE No.

INVALID PARAMETER No.

LINE No. NOT ACCESSIBLE (selective reset of an XX line).

LINE No. CAN NOT BE RESET (in class 1, recurrence 1 of XX).

PASSWORD NOT CORRECT.

COMMAND NOT POSSIBLE.

The user is invited to type the correct number.

Typing a number of a write-protected class will display the following message:

"write-protected recurrence".

During deriving, in EEPROM, of the fixed operational configuration present in RAM, the following error messages may be displayed:

COMPRESSED SIZE TOO LARGE

CCR ERROR, DO YOU WISH TO RESTORE THE CONFIGURATION?

PLEASE CONFIRM (Y/N)?

If the response is:

Y:	The last saved configuration is restored, and all modifications are lost.
N:	The modifications are saved, and others are possible to reduce the size of the file to be compressed.

End of Configuration Session and Reset

To quit the configurator and initiate the equipment reset when you have finished making changes, type:

The letter "I" if you selected a complete reset (ITO),
The letter "F" if:
- The selective reset with deriving of the configuration in EEPROM has been selected,
- If the key is correct (see "Choice of Type of Reset" in this chapter),
- If the modifications do not involve the classes not modifiable in ISE session (see Section "Choice of Type of Reset" in this chapter).
the letter "V" if:
- The selective reset without deriving of the configuration in EEPROM has been selected,
- the key is correct (see "Choice of Type of Reset" in this chapter),
- the modifications do not involve the classes not modifiable in ISE session. (see Section "Choice of Type of Reset" in this chapter).

The reset from the new configuration can be checked by displaying the welcome page of the configurator (for example).

Figure 2-9: Welcome Page of the Configurator

If the identification is that of the customer and if the counter is incremented by 1 in relation to the preceding configuration version, the equipment has been reset with the new configuration.

If the identification is 9000 and the value of the counter 00, the new configuration is wrong and the equipment has been reset with the default configuration.

In this case, it is possible to access the erroneous configuration to modify it by setting up a new configuration session.

To quit a configuration session without resetting the equipment and without updating the operational configuration in RAM, type one of the following commands:

"CTRL/P" "CLR", whether or not the key is correct, modifications made during the session are then not taken into account.
"SA" if the key is correct and if the modifications do not involve the classes not modifiable in ISE session (see Section "Choice of Type of Reset" of this chapter); command "SA" derives the fixed configuration in CONFlG RAM in EEPROM.

Note For a "call clearance" during a configuration session. the modifications made are saved. One need only re-establish the call to continue the modifications.
