4. Configuration

When the NetLink is shipped from the factory, options and parameters are set to fit the requirements of most call accounting applications.  In many cases, if you do not choose to include NetLink’s advanced features, no further configuration is required.

However, if you do intend to use advanced features (such as the Data Filter or Alarm Filter), or if your application requires parameters other than the defaults described in this section, the unit must be properly configured.  This section describes how to reconfigure the NetLink to meet the requirements of almost any data collection application.

Although NetLink provides a substantial assortment of advanced program features, it is not necessary to include all of these features in your system configuration.  You may wish to complete the basic set-up first, and then add optional features as needed.

When configuring the unit, note that the Status Screens can be accessed via item 1 in the Main Menu.  This allows you to determine the current state of any feature, and verify that parameters are correctly defined. For more information on the Status Screens, please refer to Section 6.

4.1. Access to the Command Mode

When the command mode is active, the unit will display a series of menus used to select parameters, enable options, and retrieve stored data.

During initial configuration, command mode can only be accessed via the Console Port or Modem Port.  After network parameters have been defined, you will also be able to access command mode via the Network Port. To access command mode for initial configuration, proceed as follows: 

PollCat NetLink Main Menu	Supervisor Mode

  1. Local Access:  To communicate via the Console Port, start your communications program (e.g. ProComm).

    1. If Set-Up Switch 7 is UP (enable Console Port Password), the system will send the "PollCat-NetLink" (Password) Prompt.

    2. Key in the password (case-sensitive), press [Enter]. The Default Supervisor Password is SUPER.

  2. Access Via Modem:  Start your communications program (e.g. ProComm) and dial the NetLink.

    1. The unit will send the "PollCat-NetLink" (Password) prompt after the carrier is detected.

    2. Key in the password (case-sensitive), press [Enter]. The Default Supervisor Password is SUPER.

  3. Access via Network:  During initial configuration, the NetLink cannot be accessed via Network, because parameters such as the IP address and gateway mask have not been defined yet. After network parameters have been defined (see Section 4.4.5), a Telnet session can be established using the following format:

    telnet ipaddress port [Enter]

    Where:

    ipaddress   NetLink's IP Address
    port (Optional) The desired Port Number. If omitted,
    telnet will connect to port #23 by default; Command
    Echo will be set according to NetLink's current configuration,
    and $FF Stuffing will be enabled. Options:
    2001    Behaves same as port #23.
    3001 Preconfigured with Echo enabled,
    and $FF Stuffing Off.





Notes:

After a brief pause, the NetLink Main Menu will appear as shown in Figure 4.1.



4.2. Menu System Conventions

  1. Access to Submenus: All menus are key activated. To access a menu, key in the number for the desired item and press [Enter].

  2. User Level / Supervisor Level Functions: Note that most configuration menus are not available in User Mode. In order to perform the setup procedures described in this section, the Supervisor Mode must be active. The top of the Main Menu indicates whether User or Supervisor Mode is currently selected.

    To switch from User Mode to Supervisor Mode, select Main Menu Item 3 "System Functions". When the System Functions menu appears, select item 1 "Security Level", and select Supervisor. Key in the Supervisor password (Default = SUPER) and press [Enter].

    For more information on User functions and Supervisor functions, please refer to Appendix D.

  3. Save Parameters: After NetLink has been properly configured, it is recommended to save parameters to flash memory. If parameters are not saved, the NetLink will revert to the previous configuration when power to the unit is switched off or interrupted. To save parameters, go to the Main Menu, type 7 and press [Enter].



4.2.1. Script Access to Menu Functions

NetLink menu functions can also be accessed using scripts. This allows you to create polling programs that select items from command menus in order to change parameters. When writing polling software, use the following conventions:

  1. Wait for Menu: To allow the polling program to determine when a menu has been completely sent, search for the character(s) at the end of the menu. For most menus, the last three characters will be an ellipsis (three periods).

  2. Selecting Menu Items: Specify the desired menu item by number, followed by a carriage return.

  3. Moving Up One Level: To exit from a menu and return to the previous menu, send an Escape character

Figure 4.3:  Port Selector Menu


  1. Wrap-Around:  If internal memory becomes full, the wrap-around option allows new data to be written over older data.  This enables the unit to continually recycle its memory. While command mode is active, new data will not overwrite older data in the current partition.  Any new data will be stored outside the top boundary.  If memory is full, no additional data will be stored while command mode is active. (Default = On).

    Note: When Wrap-Around is enabled and memory becomes full, there will be a noticeable delay while the unit clears old data and writes new data to flash memory. During this period, NetLink will delay response to additional commands until the wrap-around process is complete. Note that newly received data will not be lost during this delay.

  2. Real-Time Clock:  Sets NetLink’s internal clock and calendar.  Since time dependent features (e.g. Scheduled Actions, PBX Inactivity Alarm) rely on the internal clock, it is important that the clock and calendar are accurately set.



4.4. Port Configuration

To configure PBX Port A, PBX Port B, the AUX Port, Console Port, Modem Port or Network Port, go to the Main Menu, type 22 and press [Enter].  The Port Selector Menu (Figure 4.3), will be displayed.  To select and configure ports, proceed as follows.

    4.4.5. Network Port Configuration

    Settings for network parameters, such as the IP Address and Subnet Mask, will be determined by your network configuration.  Please contact your network administrator for appropriate settings, then assign parameters as described in this section.

    To configure the Network Port, go to the Port Selector Menu (Main Menu, item 22), and select item 6. The Network Port Configuration Menu (Figure 4.9) offers the following options:

    Communication Settings:

    1. IP Address:  NetLink's IP Address (Default = undefined.)

    2. Subnet Mask:  Defines NetLink's subnet mask. (Default = 255.255.255.0.)

    3. Gateway Address:  Defines NetLink's Gateway Address. (Default = undefined.)

    4. SNMP Manager 1:  Defines the IP Address for the first SNMP Manager. NetLink allows definition of two SNMP Managers. (Default = undefined.)

    5. SNMP Manager 2:  Defines the IP Address for the second SNMP Manager. (Default = undefined.)

    6. SNMP Community:  Defines the SNMP Community. (Default = public.)

    7. Reset Network:  Reinitializes the network port.

    8. Send MSS: Sets the Maximum Segment Size for TCP/IP packets sent by the NetLink. (Default = 1460.)

    9. Command Echo:  Enables / Disables the command echo for this port. During set-up, it may be helpful to enable Command Echo.  This allows keystrokes sent to the NetLink to be displayed on your monitor.  (Default = On.)

    10. Response Type:  Determines how this port will react when command mode is activated. If "Display Menu" is selected, NetLink will immediately display the Main Menu when command mode is activated. If "Inhibit Menu" is selected, NetLink will not display the Main Menu until [Enter] is pressed. (Default = Inhibit Menu.)

    11. "Sure" Prompt:  When irreversible commands (such as "Erase Data") are invoked, this port can display the "Sure" prompt to allow one last chance to verify that the command should be executed. (Default = On.)

    12. Command Timeout:  Sets the Timeout value.  If no additional command activity is detected at this port during the defined timeout period, this port will exit command mode and disconnect. (Default =15 minutes.)

    13. Audit Trail: Enables or Disables the Audit Trail function. When enabled, NetLink will log command activity at this port. To review the command activity log, please refer to Section 16.1.7. (Default = Off.)

    Action Parameters:

    1. Action Delay: When multiple alarm actions are directed to this port, the action delay determines how much time will elapse between actions. This makes it easier to connect to the port, by providing a window when the port is not busy sending out actions. (Zero to 9999 Seconds; Default = 10 Seconds.)

    Output Parameters:

    1. Output Mode:  Selects the data output format for this port; ASCII Record, Binary Block, Xmodem or Zmodem.   (Default = ASCII Record.)

      Note: When using Zmodem Output Mode, please refer to the cautions listed in Section 15.7.

    2. Data on ^B01:  When enabled, NetLink will immediately begin sending data when the data release command is invoked (Menu or ^B01). When disabled, NetLink will send the "READY" message, then wait for Command ^B02 before releasing data. (Default = On.)

    3. Hold End Data:  At the end of each data release session, NetLink will send the "End Data" message before returning to command mode.  When "Hold End Data" is enabled, this port will wait for Command ^B02 before sending the End Data message. (Default = On.)

    4. Line # Tag:  Inserts a Line Number at the beginning of each record or block released by this port.  These Line Numbers are not stored in NetLink’s internal memory, but are added when data is released.  (Default = Off.)

    5. Send Compressed:  Determines whether this port will release data in space compressed or normal format. (Default = Off.)

    6. Auto Delete:   When enabled, data will be automatically deleted from NetLink's memory at the end of each successful read. If the read is interrupted, data will not be deleted. (Default = Off.)

      Note: Before enabling the Auto Delete function, please refer to the cautions listed in Section 15.6.

    Output Parameters (Binary Block Mode Only):

    1. Transmit Attempts:  (Binary Mode Only) Determines how many times this port will resend a block after a transmission interruption, or lost connection. (Zero to 99 attempts; Default = 3.)

    2. Transmit Delay:  (Binary Mode Only) Determines how long this port will wait between transmit attempts. If this value is set to Zero, binary data will be sent in a continuous block, without acknowledgment. (Zero to 99 seconds; Default = 5 seconds.)

    3. DLE Stuffing:  (Binary Mode Only) Allows literal characters to be inserted into binary data released by this port. (Default = Off.)
