Overview of Service Provisioning for a Digital Off-Hook Configuration

This chapter provides an overview of the provisioning process for a Digital Off-Hook (DOH) configuration.

Introduction

When you provisioning service for a DOH configuration, you grant asymmetric digital subscriber line (ADSL) service to subscribers. During the provisioning process, information that you enter on the ViewRunner GUI passes immediately to the Cisco 6100 Series system by means of Simple Network Management Protocol (SNMP) set-and-get messages.

In a DOH configuration, you set up subscriber lines through the Cisco 6100/6130 universal slots using CAP ATU-C modules. You provision the Cisco 6110 chassis slots for line interface modules (LIMs) and Cisco 6120 slots for Cisco 6120 modules.

Note To convert your Cisco 6100 Series system to a Direct Connect configuration, refer to the Cisco 6100 Series with NI-1 Digital Off-Hook to Direct Connect Conversion Release Notes.

DOH Provisioning---Procedures Overview

Provisioning the Cisco 6100 Series system for a DOH configuration includes the procedures that are described in the following chapters:

For an overview of the system processes that occur during the provisioning process, see "System Processes and Performance with a Digital Off-Hook Configuration," and the ViewRunner for Windows User Guide.

Each set of procedures includes all or some of the following elements:

Description of the procedure overview and purpose
Guidelines and rules that you need to be aware of when performing the provisioning tasks
Illustrations of the dialog boxes that you open to set and monitor subscriber data
Tables that list and describe the buttons and fields in each of the dialog boxes that you use for provisioning
Step-by-step instructions to perform the provisioning task

Guidelines for Provisioning a DOH Configuration

Before you provision subscribers using a DOH configuration, review the following guidelines:

A management connection must exist for ViewRunner to provision the Cisco 6100 Series system. A Cisco 6100 Series must contain the following
hardware:
- Cisco 6100/6130
- System controller
ViewRunner must discover the system and its components.
The ViewRunner SNMP timeout default value is 1 second. For a congested network, you can use a 5-second setting.
CAP ATU-C module ports that are jumpered for Direct Connect configurations do not display in either the assigned or unassigned pool lists. See the Cisco 6100 with NI-1 Digital Off-Hook Installation Guide or the Cisco 6130 with NI-1 Digital Off-Hook Installation Guide for more information on jumpering.
ViewRunner calculates an oversubscription ratio (OSR), a key statistic in Digital Off-Hook configurations, by using formulas. Each formula provides a different view of oversubscription, as follows:
- ViewRunner keeps OSR calculations current for each logical pool.
- ViewRunner initially displays the statistics when the logical pool tab is selected.
- ViewRunner recalculates and updates all statistics in a dialog box whenever you assign or unassign a CAP ATU-C or LIM port from the logical pool.
Locking ATU-C ports increases the OSR, for example, 3:1 goes to 6:1.
Locking LIMs reduces the OSR, for example, 6:1 goes to 3:1.
Each LIM port must have a subscriber ID associated with it. You can add a new subscriber, modify, or delete an existing subscriber. If a subscriber is already associated with a port, a Subscriber ID displays on both the Module Properties dialog box Port Configuration tab and Subscriber Properties dialog box.
A port access identifier (AID) includes the chassis type and number, slot number, and port number.
