Overview of Provisioning Service for a Direct Connect Configuration

This chapter provides an overview of the provisioning process for a Direct Connect configuration.

Overview and Purpose

Provisioning service for a Direct Connect configuration is the process of granting asymmetric digital subscriber line (ADSL) and symmetrical digital subscriber line (SDSL) 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 Direct Connect installation, you set up subscribers by wiring the plain old telephone service (POTS) splitter modules directly to the ADSL transmission unit---central office (ATU-C) or SDSL transmission unit---central office (STU-C). Using this method eliminates the need for line interface modules (LIMs). The system can include one or more Carrierless Amplitude and Phase Modulation (CAP) ATU-C and STU-C modules.

Chassis architecture mandates that you insert like modules on one side of the chassis and not mix modules types in a chassis area. In other words, you cannot have both ATU-C and STU-C modules in the same side of the Cisco 6100 chassis at the same time. However, you can insert ATU-C modules on one side of the Cisco 6100 chassis and quad-port STU-C modules on the other side, for example.

Direct Connect Provisioning---Procedures Overview

The following chapters provide instructions to provision the Cisco 6100 Series system for a Direct Connect configuration:

Note Before you can begin provisioning a system, ViewRunner must discover the system and its components.

For an overview of the system processes that occur during the provisioning process, see "System Processes and Performance with a Direct Connect Configuration,"and the Cisco 6100 Series with NI-1 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 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 Direct Connect Configuration

Before you provision a Direct Connect configuration for your subscribers, review the following guidelines:

A management connection must exist for ViewRunner to provision the Cisco 6100 Series system. A Cisco 6100 Series chassis must contain at least one of the following modules:
- Cisco 6100/6130
- System controller
The Cisco 6100 Series system must be upgraded to Release 3.0.0 (or later)

Note If the node is running a release less than 3.0.0, a message displays stating that the node must be running Release 3.0.0 or later in order for the utility to execute.

ViewRunner supports the following modules:
- Dual-port CAP ATU-C
- Dual-port DMT-2 ATU-C
- Quad-port flexi ATU-C (CAP or DMT)
- Quad-port STU-C
You can choose from the following configurations when you set up a Direct Connect configuration:
- Direct Connect with a POTS splitter---In this configuration, each subscriber is connected directly to a modem. To increase subscribership, you can add additional chassis to your system. this configuration includes the Cisco 6100/6130 chassis. Dual-port CAP ATU-C, dual-port DMT-2 ATU-C, or quad-port flexi ATU-C (configured as CAP or DMT-2) modules are installed in the chassis. This configuration also includes a POTS splitter chassis, either Cisco 6120 or a Siecor POTS splitter, with CAP POTS or DMT POTS modules installed in the chassis.
- Direct Connect without a POTS splitter---In this configuration, each subscriber is directly connected to a modem. To increase subscribership, you can add more chassis to your system. This configuration includes the Cisco 6130 chassis. Dual-port DMT-2 ATU-C, quad-port flexi ATU-C (configured as CAP or DMT-2), or quad-port STU-C modules are installed in the chassis.
You can use only a Cisco 6130 chassis with a Direct Connect configuration that does not have a Cisco 6120.
If you are using a Cisco 6130 in your configuration, you will only be allowed to select 4 ports.
If you are using a Cisco 6100 in your configuration, you can select either 2 ports or 4 ports.
ViewRunner for HP OpenView will verify if the LIM chassis has been disconnected. If the LIM is not disconnected, there will be a message stating that the LIM chassis needs to be disconnected before proceeding further.
To test a customer premises equipment (CPE) module port using the system controller without disconnecting the near-end cable access to the CPE line, use the ViewRunner test bus support feature. Be aware of the following guidelines when you run this test:
- Ensure that the CPE port is locked.
- Ensure that the Maintenance state is set to Network Loopback.
- If you remove the port from the Maintenance state, test bus support is automatically disabled.
A quad-port STU-C module lists four port options, and an ATU-C module lists two port options.
After the migration is complete, there should be an ascii file in $VRS_HOME/log containing a list of the subscribers that were moved and to or from what port they were moved.

Note You can move no more than 64 subscribers.

Refer to the Cisco 6100 Series with NI-1 User Guide for descriptions of and instructions for setting up these configurations.
