This chapter describes how to add subscribers and create subscriber configurations using CDM. This chapter also includes instructions for setting up subscriber permanent virtual channels and transit subscriber virtual channels.
This chapter includes the following sections:
You can configure subscriber properties for both preprovisioned modules and modules that the software detects after you deploy the DSLAM chassis. When you preprovision the settings for a subscriber, this subscriber is not in service until you have inserted the module and commissioned the Cisco DSLAM chassis.
When you create subscriber properties, you use the Create Subscriber Dialog windows. This section gives an overview of the Create Subscriber Dialog windows for each of the types of modem ports—CAP ADSL, DMT-2, and STU-C (for Flexi line cards, refer to the appropriate module type, either CAP ADSL or DMT-2). A special section of guidelines for setting Reed-Solomon coding on CAP ADSL modules is also included. Instructions for setting subscriber values are in the "Steps for Creating Subscriber Properties" section.
This section includes the following topics:
To create subscribers on CAP ADSL modem ports and set values for these subscribers, open the Create Subscriber Dialog on CAP ADSL Modem Port window, which is shown in Figure 3-1. To open the window, see "Steps for Creating Subscriber Properties" section.
Table 3-1 describes the fields in the Create Subscriber Dialog on CAP ADSL Modem Port window.
| Field | Description |
|---|---|
Use this field to input the ID for a new subscriber. Enter 1 to 20 alphanumeric characters. |
|
Use this field 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). |
|
Use to enable Reed-Solomon coding. Choose one of the following settings: See the "Guidelines for Setting Reed-Solomon Coding" section for more information about setting this field. |
|
Enter the value that reflects the type of CPE that is connected to the Cisco DSLAM chassis. Use the service provider standard setting or choose 0. |
|
Enter the setting for the maximum trained upstream rate of a subscriber modem. Use the tooltips to select the valid configuration settings, which are measured in kilobits per second. |
|
Enter the setting for the maximum trained downstream rate of a subscriber modem. Use the tooltips to select the valid configuration settings, which are measured in kilobits per second. |
|
Enter an associated upstream margin value for a subscriber. Use the tooltips to select the valid choices for this value. Note Margin values are assigned by the service provider and based on a subscriber service order. |
|
Enter an associated downstream margin value for a subscriber. Use the tooltips to select the valid choices for this value. |
|
| 1CAPRSC = CAP Reed-Solomon coding
2CPE = customer premises equipment 3PSD = power spectral density |
You can configure Reed-Solomon error coding per subscriber.
 |
Note You can disable Reed-Solomon coding for the 136 kilobaud rate in the downstream direction for CAP ADSL modules only. |
Consider the following guidelines in relation to using Reed-Solomon coding:

This section describes how to set up transit subscribers on subtended systems and how to set subtended subscriber PVCs and includes the following topics:
Subtending allows you to use one ATM backbone for multiple Cisco 6100/6130 DSLAM chassis. Subtending is a DSLAM feature that reduces the cost per subscriber by amortizing the expense of the network interface module and the edge-switch port connection over a large number of subscribers. Subtending provides the following advantages:
Figure 3-13 illustrates the connections of a subtended DSLAM system with six subtended systems.
Figure 3-14 shows valid address ranges for each DSLAM.
The following guidelines apply to subtending Cisco 6100/6130 DSLAM chassis nodes:
For example, if you assign subscriber A to VPI 5 and VCI 10 on the subtended Cisco 6100/6130 DSLAM, you must assign transit subscriber A to VPI 5 and VCI 10 on the host system. Transit subscribers on the subtending host system are logical containers for traffic that passes from the subtended DSLAM; therefore, you can create multiple transit subscribers on one port.
To subtend a Cisco 6100/6130 DSLAM chassis, you create settings for the local transit subscribers in the same manner as you would any subscribers. The subtend module should be preprovisioned on your system. The subtend module displays on the left side of the Map Viewer window as C6100v30SubtendPort; each subtend module has two ports.
Complete the following steps to create transit subscribers:
Step 2 From the object menu, right-click C6100v30SubtendPort to open another object menu.
Step 3 Choose Open Transit Subscriber Create/Config/Delete Dialog from the object menu.
The Transit Subscriber Create/Config/Delete/Info window, shown in Figure 3-15, opens.
Step 4 In the Create New Transit Subscriber area, enter the ID for this subscriber in the Subscriber ID field.
Step 5 Click Create Transit Subscriber.
Step 6 Continue to enter subscriber IDs for each transit subscriber, and then click Create Transit Subscriber.
The transit subscribers that you create are visible on the left side of the Map Viewer window under the C6100v30SubtendModule, C6100v30SubtendPort views, and display as C6100v30trSubscr. See the "Steps for Creating Subscriber Properties" section for steps to set the subscriber values for each transit subscriber and the "Changing Subscriber Properties" section for steps to change subscriber settings.
