Overview of Provisioning Service for a Digital Off-Hook Configuration
This chapter provides an overview of the provisioning process for a Digital Off-Hook (DOH) configuration.
Provisioning service for a DOH configuration is the process of granting asymmetric digital subscriber line (ADSL). 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.
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 HP OpenView 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
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 modules:
- ViewRunner must discover the system and its components.
- The ViewRunner SNMP timeout default value is 1 second. A 5-second setting can result in a slow response time.
- 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 Direct Connect Installation Guide or the Cisco 6130 with NI-1 Direct Connect 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.
- After you add a module to the Cisco 6100 Series system, you must manually configure each line to be a member of a logical pool. Each port (either LIM or dual-port CAP ATU-C) can be a member of only one pool at a time.
- Only LIM and CAP ATU-C ports within a physical pool are candidates for assignment to a logical pool that belongs to that physical pool.
- 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.
- In View All Equipment, a port access identifier (AID) includes the chassis type and number, slot number, and port number.
- The default noise margins are 6 dB upstream and 3 dB downstream.
