This chapter describes how to assign CAP ATU-C and LIM ports to a pool and associate subscribers to LIM ports. These tasks are the major provisioning tasks for a Digital Off-Hook (DOH) configuration.
This chapter includes the following sections:
When you provision subscribers, you assign LIM ports to subscribers 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 Digital Off-Hook 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 and deleting subscribers' port associations.
In their initial state, discovered resources (LIM ports and CAP ATU-C module ports) are in their respective unassigned windows. The list boxes that are located on the bottom third of the Pool Window dialog box, Pool tab display unassigned LIM ports.
Figure 3-1 shows the assignment of ports to pools.
Complete the following steps to assign CAP ATU-C and LIM ports to a pool:
Step 2 Click Assign Ports Now.
Step 3 To choose more than one pool, follow these steps:
a. Choose a sequential range of ports by first clicking the beginning port and then pressing the Shift key as you click the last port in the range.
b. To choose nonsequential list box ports, press the Ctrl key as you click the ports that you want to choose.
 |
Note The Oversubscription Ratios field at the top of the dialog box changes dynamically, according to the number of LIM ports and CAP ATU-C module ports that you drop into the top list boxes. |
Each list box displays the port access identifier (AID). In addition, ViewRunner displays the Administrative state and Service state for each port and supporting module. In the case of LIM ports, ViewRunner also displays the associated subscriber's Administrative state.
You can add or delete a subscriber from the LIM Properties dialog box by completing the following steps:
Step 2 Choose Port Properties > Configuration.
The LIM Module Properties dialog box Port Configuration tab opens (Figure 3-3).
|
Note The Add Subscriber button is dimmed if you do not have pools. |
Table 3-1 describes the fields on the LIM Properties dialog box.
| Field | Description |
|---|---|
Administrative State | Displays the status of the Administrative state, either Unlocked or Locked. Defaults to Locked. |
Allows configuration of a unique subscriber identifier. | |
Allows configuration of a unique identifier assigned to this copper local-loop circuit. | |
Displays the physical pool to which this LIM port belongs. | |
Displays the pool to which this LIM port belongs. | |
Allows you to edit the pool with which this LIM port is associated. | |
Allows you to add or edit a subscriber to this LIM port. This button changes to Edit Subscriber if you are viewing a specific subscriber. |
You can add a subscriber to a module on the Subscriber Properties dialog box, which you access through the LIM Module Properties dialog box by clicking Add Subscriber. The Subscriber Properties dialog box is shown in Figure 3-4. The fields on the Subscriber Properties dialog box are described in Table 3-2.
| Field | Description | ||
|---|---|---|---|
Displays the Administrative state of the subscriber, either Locked or Unlocked. | |||
Subscriber ID | Required field that must contain 1 to 20 alphanumeric characters. ViewRunner does not guarantee the uniqueness of subscriber IDs. ViewRunner does not allow you to modify subscriber configuration parameters unless you enter an alphanumeric character.
Subscriber ID is a nonservice-affecting parameter for the Cisco 6100 Series system. You can modify the Subscriber ID field when the subscriber is unlocked. | ||
Service Provisioning button | Click to open the Service Provisioning dialog box. See the "Guidelines for Adding New VPI/VCI Addresses" section for more information on using this dialog box. | ||
Subscriber Association to Port | 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 CPE1). 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). | ||
| Service Configuration Group Box | |||
Limits the maximum trained rate of a subscriber's modem. Use the up and down arrows to choose valid settings, which are measured in kilobits per second. The downstream and upstream selections are independent. See the "Training Process" section for more information about line training. | |||
Margin Configuration (Downstream and Upstream) | Allows you to associate an upstream margin and a downstream margin value with a subscriber by using the down arrow to choose valid settings in decibels. See the "Bit Error Rate and Noise Margin" section for more information on setting the margin configuration.
| ||
PSD2 Transmit Power | Allows you to specify downstream and upstream values in dBm/HZ for PSD transmit power. Transmit power is a measure of the downstream PSD mask. To avoid transmission errors, set the downstream channel to -40 dBm/Hz. Use the down arrows to choose from the available rates. | ||
Allow 136K Baud | The 136 kilobaud training rates now can be enabled or disabled through a system-wide MIB3 object. If the 136 kilobaud training rates are disabled, those selections are shaded in ViewRunner and therefore not selectable by you. CAP modules support 136 kilobaud training rates, which can be allowed or disallowed when the feature is supported by the system controller software revision and the subscriber is locked. If the system controller supports per-subscriber provisionable 136 kilobaud or does not support ATUCPARMS, the "Allow 136K Baud" check box on the 6100 Properties dialog box is disabled. (See the ViewRunner for HP OpenView User Guide.) If the system controller supports ATUCPARMS but does not support per-subscriber 136 kilobaud, the option is enabled. | ||
CPE Signature | Allows you to set the signature of the CPE unit. Use the up and down arrows to set this value. | ||
| 1CPE = customer premises equipment 2PSD = power spectral density 3MIB = management information base |
Complete the following steps to add a subscriber on the LIM.
Step 2 Set the Administrative State to Locked or make sure it is set to Locked.
Step 3 Enter the name (identifier) of the subscriber in the Subscriber ID field.
Step 4 Verify that the fields in the Subscriber Association to Port group box for module AID, port number, and Circuit ID are correct.
Step 5 Set the Max Allowed Rates for Downstream and Upstream by using the up and down arrows.
The default settings are 7168 downstream and 1088 upstream. The following settings are valid:
Step 6 Set the Margin Configuration Downstream and Upstream values by using the down arrows.
The default settings are 3 dB downstream and 6 dB upstream. The following settings are valid:
Step 7 Set the PSD Transmit Power Downstream and Upstream values by using the down arrows.
The default settings are -40 dBm/Hz downstream and -38 dBm/Hz upstream. The following settings are valid:
Step 8 Set the CPE Signature by using the up and down arrows.
The default is 0, and the range is 0 to 127. This setting is a hardware identifier for the subscriber modem and is usually only used with older modems.
Step 9 Set the Downstream fields in the CAP Rates group box as follows:
a. Select the Allow 136 K Baud feature to enable it. The default is disabled.
b. Select the Reed Solomon field to enable it, and then set it to Long interleave, Short interleave, or Disable 136 dn strm (downstream), by using the down arrow. The default is disabled. (See the "Reed-Solomon Coding Module Applications" section for more information on this setting.)
Step 10 Set the Upstream fields in the CAP Rates group box as follows:
a. Select the Allow 17 K Baud feature to enable it. The default is disabled.
b. Select the Allow 68 K Baud field to enable it. The default is disabled.
Step 11 Click OK or Apply to save these settings.
Step 12 Repeat Step 3 through Step 11 for each subscriber that you want to add.
You can add subscribers only when a subscriber does not already exist for the port. This restriction prevents you from assigning more than one subscriber ID for each LIM port.
To delete a subscriber, complete the following steps:
Step 2 Click Edit Subscriber to open the Subscriber Properties dialog box.
Step 3 Click Delete Now.
|
Note The Delete Now button is dimmed unless the subscriber is locked. If the subscriber's Administrative state has been changed to Locked since you opened the dialog box and you have not yet applied that configuration, the Lock Confirmation dialog box opens when you click Delete Now. |
Step 4 Click OK in the Confirmation dialog box, shown in Figure 3-5, for the changes to take effect.
