Configuring the Cisco NI-1 DLSAM Equipment Module

Supported Configurations

Two configurations are possible with this system:
• Subscriber Connection Configurations
• Subtending Configurations
CHAPTER
6

Subscriber Connection Configurations

Subscriber Connection configurations include the following:
• Direct Connect Configuration.
This involves connecting one subscriber directly to a modem (ATU-C or STU-C). Traffic is multiplexed from up to 64 ADSL or 128 SDSL subscriber ports to a single ATM WAN port.
• Digital Off-Hook Configuration (DOH).
This configuration uses a combination of a Multiplexer Chassis (MC), Line Concentration Chassis (LCC), and POTS Splitter Chassis (PSC) to provide the highest subscriber concentration. This configuration uses ADSL technology to support up to 400 ADSL users through 64 ADSL modem ports, allowing connections to be made when they are needed (i.e., dial up). If a connection is not established, the central office modem resources are made available to another CPE.

Subtending Configurations

Subtending Configurations include the following:
• Non-subtended Network Configuration.
Allows individual DSLAMs to be directly linked to the WAN via a trunk that comes from the WAN port.

Chapter 6 Configuring the Cisco NI-1 DLSAM Equipment Module
Note In order to configure the NI-1 DLSAM Equipment Module you must have installed it
during the CPC Server and Client installation procedures. For more information about installing CPC, refer to the chapter titled "Initial Installation" in the Cisco Provisioning
Center Installation and Administration Guide.

Summary of Configuration Tasks

To configure the Equipment Module to make CPC operational, you must complete the following steps:
Step 1 Network Timeout.
Step 2 Initial system upload.
Step 3 Re-upload (if configuration information has changed).
Step 4 Add inter-network links (topology) information.
Step 5 Configure Service element profiles.
Summary of Configuration Tasks

Network Timeout

The NI-1 DLSAM Equipment Module implements an overall timeout for service provisioning transactions. There are two environmental variables that define the Network Timeout. These are CCP_ACTIVATION_TIMEOUT (Default=120 seconds) and CCP_RESET_TIMEOUT (default= 300 seconds); they define the maximum interval (measured in seconds) allowed for each Service element activation and for the rollback of each Service element, respectively. The maximum interval must amount to the maximum time to elapse before the NIF times out. For example, if CCP_ACTIVATION_TIMEOUT=180, this allows the NIF three minutes to activate an item in a Transaction.
Default settings are used if the NIF detects that these variables are not set in the environment.
Network timeout requires shutting down the server if it is not already down, setting the variables and then restarting it to pick up the environment changes.
To set the CCP_ACTIVATION_TIMEOUT environment variable:
Step 1 Shut down the CPC server by issuing the following command:
SYnpt -h
Step 2 Set the environment variable to an integer (measured in seconds) that amounts to the maximum time to
elapse before the NIF times out:
export CCP_ACTIVATION_TIMEOUT=180
To set the CCP_RESET_TIMEOUT environment variable:
Step 3 Set the environment variable to an integer (measured in seconds) that amounts to the maximum time to
elapse before the NIF times out:
export CCP_RESET_TIMEOUT=180

Initial System Upload

Step 4 Run the following commands in succession to source the Server environment and start the CPC Server:
cd /opt/SY/Activator/Server/mng/utility . syccpovdef SYnpt -sS
Initial System Upload
In order to provision services, the CPC database must have detailed knowledge of the managed subnetworks. Using a procedure called upload, objects are created within the CPC database that represent objects of the managed network.
Note The term upload does not refer to the creation of inter-network links because they are
outside the scope of any single Equipment Module. For more information on adding inter-networking links, see the section titled “Adding Inter-Network Links (Topology) Information” in this chapter.
Chapter 6 Configuring the Cisco NI-1 DLSAM Equipment Module
CPC supports the following types of upload:
• fabric (nodes, DSL physical ports, WAN physical ports, WAN subtending ports, ATM logical ports)
• Service (ATM cross connections)
• fabric and Service (all)
For the Cisco 6100/6130 NI-1 Equipment Module you can upload many nodes at once (network upload) or an individual node at a time. CPC supports the following upload scenarios:
• Given a network object, upload just the fabric elements for the nodes in that network.
• Given a network object, upload just the Service elements for the nodes in that network.
• Given a network object, upload all the fabric and Service elements for the nodes in that network.
• Given a node object, upload just the fabric elements for that node.
• Given a node object, upload just the Service elements for that node.
• Given a node object, upload all fabric and Service elements for that node.
Note The upload function takes precedence over any Transactions that are running at the time of
upload. If the upload function makes a change back to the fabric that affects a running Transaction (such as deleting a logical port that the Threader has decided to use) then this Transaction fails and must be restarted.
Network and node objects must be created in order to perform an Upload.

Network Upload

Uploading the Fabric and Service Elements for a Network Object

You can upload the fabric and Service elements for a network object by completing the following steps:
Step 1 From the Root Tree Viewer choose Network > Cisco NI1 DSLAM Network Name.
Step 2 Select Upload Both from the Element menu. The upload begins.
When the upload is complete, an upload status window will display. If there were errors during the upload they would appear in this window.

Chapter 6 Configuring the Cisco NI-1 DLSAM Equipment Module

Uploading the Fabric Elements for a Network Object

Given that the network object is in place, you can now upload fabric. Uploading network fabric creates the node objects corresponding to the specified network. Any fabric element contained by the nodes is also uploaded.
Step 1 From the Root Tree Viewer choose Network > Cisco NI1 DSLAM Network Name.
Step 2 Select Upload Fabric from the Element menu. The upload begins.
When the upload is complete, an upload status window will display. If there were errors during the upload they would appear in this window.

Uploading the Service Elements for a Network Object

After you have uploaded the fabric elements you can upload the services.
Step 1 From the Root Tree Viewer choose Network > Cisco NI1 DSLAM Network Name.
Step 2 Select Upload Services from the Element menu. The upload begins.
When the upload is complete, an upload status window displays. If there were errors during the upload they would appear in this window.
Initial System Upload

Uploading for Individual Nodes

Uploading the Fabric and Service Elements for a Node Object

After you create a node object, you may want to upload all of the fabric and Service elements for that node. The fabric elements for a Node object are the node itself, physical ports and logical ports. The Service elements are the objects used to create services (cross connections). Complete the following steps to upload the fabric and Service elements:
Step 1 From the Root Tree Viewer choose Network > Cisco NI1 DSLAM Network Name > Cisco NI1 DSLAM
Node > Node Name.
Step 2 Select Upload Both from the Element menu. The upload begins.
When the upload is complete, an upload status window displays. If there were errors during the upload they would appear in this window.
