This chapter describes the subscriber provisioning process and includes illustrations and descriptions of the dialog boxes in which you provision service for subscribers, procedure guidelines, and step-by-step instructions to provision subscribers using a Direct Connect configuration. This chapter also includes information about configuring modules that provide special settings. This chapter is oriented from the viewpoint of the operator who is using the ViewRunner graphical user interface (GUI) to set up new subscribers or to change the settings for existing subscribers.
This chapter includes the following sections:
When you provision subscribers, you associate subscribers to ports and define each subscriber's initial level of service. Finally, you establish the virtual circuit and path that the subscriber's data is to follow, which is described in "Configuring ATM Virtual Channels for a Direct Connect Configuration."
The port to which you associate a subscriber reflects the level of service that a subscriber selects in relation to the capabilities of the available telco equipment that a subscriber is using. As this relationship changes, you can maintain a consistent quality of service by subsequently adding or deleting subscribers' port associations.
 |
Note See the overview chapter in the ViewRunner for Windows User Guide for a review of how to navigate on the GUI. |
Consider the guidelines that follow before you provision your subscribers. Following these guidelines can help you avoid making errors when you establish ATM connections.
The following guidelines apply to setting up subscriber and circuit IDs:
You can use the power spectral density (PSD) transmit power feature with ATU-C modules only. ViewRunner does not support the PSD transmit power feature for quad-port STU-C modules. This feature sets downstream transmit power in dBm/Hz per subscriber.
The following guidelines apply to setting training rates, margin errors, and the priority queue:
When you provision subscribers, you associate subscribers to ports, identify the port to which each subscriber is connected, and then you define subscribers by specifying the subscriber ID for each subscriber and, optionally, the circuit ID for each subscriber. Once you define a subscriber, you can add a new subscriber, delete a current subscriber, or modify the parameters of a current subscriber. You can customize a subscriber's port association by changing the defaults. (See the "Setting Subscriber Defaults in the subscriberdefaults.ini File" section for information on changing the subscriberdefaults.ini file.)
Complete the procedures in the sections that follow to associate subscribers to ports. These procedures are found in the following sections:
|
Note The Status and Configuration tabs on the dual-port DMT-2 ATU-C module and ports dialog boxes are similar to those of the dual-port CAP ATU-C module. For this reason, illustrations of and references to the CAP ATU-C module dialog boxes also refer to the dual-port DMT-2 ATU-C module dialog boxes. The Status and Configuration tabs on the quad-port STU-C module dialog boxes are represented separately if they differ from those of the ATU-C module, in ways other than the number of ports present. |
This section describes how to use the system file called subscriberdefaults.ini to set subscriber defaults. This file is part of your ViewRunner installation and retains any values that you set in a previous installation of ViewRunner 3.0.0. An example of the file is included at the end of this section. For more information about installing this file, see the ViewRunner for Windows Installation and Administration Guide.
To edit the default subscriber values, complete the following steps:
Step 2 From your Windows Start menu, choose Program > Accessories > Notepad.
Step 3 In Notepad, choose Open from the File menu.
Step 4 Find the Winnt folder on your hard drive, and then the subscriberdefaults.ini file.
Step 5 Double-click the subscriberdefaults.ini file to open it.
Step 6 Find the line that you want to modify; place your cursor on this line and type in the new value.
Step 7 Repeat Step 6 for all of the default values that you want to change.
Step 8 Save the file by choosing the Save from the File menu when you have finished modifying the values that you want to reset.
Step 9 Close Notepad.
ViewRunner reads the new values and displays them in the Subscriber Properties dialog box.
|
Note You must access the subscriberdefaults.ini file using Notepad every time you want to modify the provisioned values for a subscriber. |
An example of a subscriberdefaults.ini file follows. Sections are separated by square brackets [ ].

Complete the following steps to determine which subscribers and ports are already set before you associate subscribers to ports:
Step 2 Select Port Service Configuration from the Chassis menu.
|
Note To access this chassis menu, right-click anywhere in the frame or on the edge of the GUI chassis view. You cannot access this menu by clicking on any of the modules within the chassis. |
The Port Service Configuration dialog box opens, shown in Figure 2-1. From this dialog box, you can view all of the available ports, and those that are in service or capable of service.
Step 3 Find the name of the port that you want to view in the PORT AID column and click on its hyperlink (the blue, underlined text that names the port).
The Module Properties dialog box, shown in Figure 2-2, opens at the Port Configuration tab for the port that you have selected.
|
Note You can also access the Module Properties dialog box by right-clicking a module and choosing Port Properties and Configuration. |
Table 2-1 describes the fields for this dialog box.
:
| Field | Description |
|---|---|
Displays the status of the Administrative state, either Unlocked or Locked. The default is Locked. When you first insert a module into the chassis, it is locked. | |
Select Normal or Maint. This field is dimmed until you set the Administrative state to Locked. Select Maint if you want to enable the Test Bus State field, which is dimmed until you select Maint. This field is always dimmed for a Flexi module. | |
Select Enable or Disable to set up the test bus. This field is dimmed for a Flexi module. | |
Inventory Details Firmware Version | Displays the current version of the module firmware. Use this field to make sure you are using the correct version. |
Subscriber ID | Displays the ID of the subscriber. The subscriber ID allows you to configure a unique record identifier for a subscriber. |
Allows you to add a subscriber to this port or edit a subscriber's port configuration. The Add Subscriber button displays if you are adding a new subscriber; the Edit Subscriber button displays if you have already assigned a subscriber to this module. |
You can use the test bus feature to test a customer premises equipment (CPE) connection. The test bus feature allows you to place a CPE into test mode with the system controller without disconnecting the near-end cable access to the CPE line. You can only test one port at a time.
|
Note The test bus feature is available for Direct Connect configurations only. |
Complete the following steps to enable the test bus in ViewRunner:
Step 2 Choose Port Properties and Configuration.
The Module Properties dialog box Port Configuration tab, shown in Figure 2-3, opens.
Step 3 Click Locked in the Administrative State field to lock the port.
Step 4 Click Maint in the Maintenance State field to lock the port.
|
Note If you change the Maintenance State field back to Normal, the test bus automatically reverts to disabled, the default. |
Step 5 Click Enable in the Test Bus State field to enable the test bus.
If the test bus fails, ViewRunner generates an alarm.
Step 6 To get information about the alarm, click the Alarm icon on the ViewRunner toolbar or choose Current Alarms View from the View menu to view the Current Alarms dialog box.
To set subscriber properties for service or change the settings for a current subscriber, you use the Subscriber Properties dialog box. You access this dialog box through the Module Properties dialog box, described in the preceding section.
Figure 2-4 shows the Subscriber Properties dialog box for the ATU-C module, and Figure 2-5 shows the Subscriber Properties dialog box for the STU-C module.
This section includes general descriptions of the fields and buttons that you use to provision service for a subscriber, and gives instructions for setting up a subscriber. See the "Configuring Subscriber Properties for a DMT-2 ATU-C Module" section for instructions that are specific to setting subscriber properties for a DMT-2 ATU-C module.
Table 2-2 describes the fields in the Subscriber Properties dialog box.
:
| Field | Description | ||
|---|---|---|---|
Use to set the Administrative state of the subscriber, either Locked or Unlocked.
| |||
Subscriber ID | Displays the ID of the associated subscriber if you have already added that subscriber. Or you can input the ID for a new subscriber in this field, in which case you must enter 1 to 20 alphanumeric characters. ViewRunner cannot guarantee that the number you enter is unique. ViewRunner does not allow you to modify service provisioning parameters unless you enter an alphanumeric character in the Subscriber ID field.
| ||
Click to open the Service Provisioning dialog box. See the "Viewing VPI/VCI Addresses Using the Subscriber PVCs Dialog Box" section for more information on using this dialog box. | |||
Displays the module AID and port number that are associated with this subscriber. | |||
Circuit ID | Allows you to configure an identifier that is assigned to the local loop (the phone line that goes to the CPE). Setting this field is optional. The Circuit ID depends on whether a port is a competitive local exchange carrier (CLEC) or an independent local exchange carrier (ILEC). | ||
Limits the maximum trained rate of a subscriber's modem. Use the down arrow to select the valid configuration settings, which are measured in kbps. The following rates are defaults for a CAP ATU-C module:
The default line rate for an STU-C module is 784 upstream and downstream. | |||
| ATU-C Modules Only | |||
Allows you to associate downstream and upstream margin values with a subscriber. Use the down arrows to scroll to the value that you want to set for Downstream and Upstream. (See the "ADSL Training Process" section for more information on setting the margins.)
The defaults are as follows:
| |||
PSD sets downstream and upstream transmit power in dBm/Hz per subscriber. Verify that the PSD complies with the service provider standards or as specified on the related service order for the subscriber line that you are provisioning. The following PSD downstream ranges are valid:
The following PSD upstream ranges are valid:
These settings are not available for DMT-2 ATU-C or quad-port STU-C modules. | |||
Use the up and down arrows to set this value. This value reflects the type of CPE that is connected to the Cisco 6100/6130. Use the service provider standard setting or choose 0 for the Cisco default. | |||
Select this field to enable 136 kilobaud downstream and Reed Solomon coding. (For specific guidelines about Reed Solomon coding, see "Reed-Solomon Coding Module Applications" section.) Choose one of the following settings:
By default, the setting for the Allow 136K Baud field is disabled. | |||
Select one of the following fields to set the upstream baud rate for CAP ATU-C modules:
By default, these settings are disabled. | |||
This section describes how to set the subscriber properties for CAP ATU-C, Flexi ATU-C (CAP), and STU-C modules. See the "Configuring Subscriber Properties for a DMT-2 ATU-C Module" section for instructions that are specific to subscribers using a DMT-2 ATU-C module.
While the Module Properties dialog box is open and after you have completed the steps in the "Associating Subscribers to Ports" section, complete the following steps to set up a subscriber:
The Subscriber Properties dialog box opens (refer to Figure 2-4 and Figure 2-5).
Step 2 Click Locked in the Administrative State field if you are editing a subscriber's properties.
If you are adding a new subscriber, the Administrative State automatically defaults to Locked.
|
Note When you lock or unlock modules or ports of trained modems, ViewRunner issues a series of warning messages. You can click Cancel if you want to abort the action. If you click Cancel, the screen refreshes and ViewRunner resets the fields to their original values. |
Step 3 Click Apply at the bottom of the dialog box to set the subscriber to locked so that you can enter data into the fields.
|
Note You can click Apply at any time after you enter data into a field. Doing this saves the change, but keeps the dialog box open. |
Step 4 Enter the appropriate data into the following fields, and then click Apply for the settings to take effect.
a. Subscriber ID
b. Circuit ID (See a discussion of circuit ID in the "Guidelines for Provisioning Subscribers" section.) This setting is optional.
Step 5 Choose the value for the Maximum Allowed Downstream and Upstream Rates by using the down arrow to choose a value.
These rates are assigned by the service provider based on the subscriber's service order. The default rates are 7168 downstream and 1088 upstream for CAP ATU-C and Flexi ATU-C modules. The default line rate for an STU-C module is 784 upstream and downstream.
|
Note If you are provisioning subscribers to STU-C modules, click Apply and you are finished with this procedure. You can proceed to "Configuring ATM Virtual Channels for a Direct Connect Configuration," for instructions to set up the PVCs for the subscribers whose properties you have provisioned. Click OK to close the dialog box. |
|
Note The remaining steps apply to CAP ATU-C and Flexi ATU-C modules only. See the "Configuring Subscriber Properties for a DMT-2 ATU-C Module" section for instructions on provisioning subscribers for that type of module. |
Step 6 Choose the downstream and upstream values for Margin Configuration by using the down arrow.
These values are assigned by the service provider based on the subscriber's service order. The default values are 6 dB upstream and 3 dB downstream.
Step 7 Choose the PSD Transmit Power for Downstream and Upstream by using the down arrow in these fields.
The default values for CAP ATU-C modules are -40 dBm/Hz Downstream and -38 dBm/Hz Upstream.
Step 8 Enable or disable the CPE Signature feature; set the signature within a 0 to 127 range.
This setting is mostly used for older modems for the purposes of hardware identification.
Step 9 Enable or disable the 136 kilobaud feature by selecting Allow 136K Baud in the CAP Rates Downstream group box.
If you select Allow 136K Baud, you can then choose from the following Reed Solomon settings:
Step 10 Select Allow 17K Baud or Allow 68 K Baud in the CAP Rates Upstream group box.
|
Note To use the 16 kilobaud and 17 kilobaud rate you must also upgrade the CPE. |
The default for each of these selections is deselected, or disabled.
Step 11 Click OK or Apply to save the settings (clicking OK saves changes and closes the dialog box; clicking Apply saves the changes and leaves the dialog box open.)
|
Note For the specific and the most up-to-date information about upstream and downstream baud rates and corresponding bit rates, refer to the Release Notes for ViewRunner for Windows 3.0.0. |
To delete a subscriber, complete the following steps:
Step 2 Set the Administrative State to Locked.
Step 3 Click Delete Now.
|
Note The Delete button is only available if the subscriber is locked. If the modem is trained and you click Locked, the Lock Confirmation dialog box opens. |
Step 4 Click OK to save and close the dialog box, or click Apply to save and keep the dialog box open.
You can use the Subscriber Properties dialog box for a DMT-2 ATU-C module, shown in Figure 2-6, to set specific subscriber properties that are available for configurations that are using discrete multi-tone (DMT) transmission. Figure 2-7 shows a Subscriber Properties dialog box for a DMT-2 ATU-C module with G.Lite Mode selected.
This section includes a description of the Subscriber Properties dialog box fields and instructions for setting these fields.
In addition to the fields that are described in the "Using the Subscriber Properties Dialog Box" section and the "Setting Subscriber Properties" section, the DMT-2 Parameters group box on the Subscriber Properties dialog box, shown in Figure 2-8, provides additional settings that are relevant to DMT transmissions. These settings include overhead framing, trellis coding, bit swapping, training mode, interleaved delay, and forward error correction (FEC) redundancy bytes.
Refer to Table 2-2 for descriptions of the fields at the top of the Subscriber Properties dialog box for a DMT-2 ATU-C module. Table 2-3 describes the fields in the DMT-2 Parameters group box. Any settings for DMT-2 Parameters running in G.Lite Mode that differ are noted in this table.
| Fields | Definition | ||
|---|---|---|---|
| |||
Choose StandardTrain or FastTrain, as follows:
These settings are also available for G.Lite Mode. | |||
The data path can be Interleaved or Fast; the default is Interleaved. The following values are valid:
| |||
FEC Redundancy Bytes | Forward Error Correction Redundancy Bytes include the following choices:
| ||
Trellis Code | Trellis coding is a method of FEC that allows the receiving modem to determine whether a given signal element is received in error.
| ||
Click the box to enable; the default is disabled. This feature allows reallocation of bits within the DMT spectrum by enabling an ADSL system to change the number of bits that are assigned to a subcarrier or change the transmit energy of a subcarrier without interrupting data flow. |
Complete the following steps to set the fields in the Subscriber Properties dialog box:
The Subscriber Properties dialog box opens (see Figure 2-6 and Figure 2-6).
Step 2 Click Locked in the Administrative State field if you are editing a subscriber's properties.
If you are adding a new subscriber, the Administrative State automatically defaults to Locked.
|
Note When you lock or unlock the modules or ports of trained modems, ViewRunner issues a series of warning messages. You can click Cancel if you want to abort the action. If you click Cancel, the screen refreshes and ViewRunner resets the fields to their original values. |
Step 3 Click Apply at the bottom of the dialog box to set the subscriber to locked so that you can enter data into the fields.
Step 4 Enter the appropriate data into the following fields, and then click Apply for the settings to take effect.
