You must complete the following provisioning tasks for the Basic and Enhanced PCE to function as expected:

  • A VPC must be created and configured at MTP3 on the public network for each public gateway that exists at PCE.

  • A public gateway must be created and configured at PCE. The PC of this gateway is the address to where the public nodes send messages.

  • A VPC must be created and configured at MTP3 on the private network for each public node that exists at PCE.

  • A public node must be created and configured at PCE for each public switch that is sending messages from and to PCE.

  • A private node must be created and configured at PCE for each private switch that is sending messages from and to PCE.

  • For ISUP traffic, trunk mappings must be created and configured at PCE to map defined CIC ranges.

The following figure is a visual representation of a roadmap that shows the task sequence (from a top down and left to right direction) for provisioning MTP3 and PCE. You may not have to perform all the tasks illustrated. The presented provisioning tasks depend on your network configuration.

Before you start PCE provisioning, you must configure the PCE system-wide attributes (refer to Initial PCE Configuration Tasks) and PCE NA management attributes (refer to Configuring the PCE NA Manager).

Note

When provisioning an Enhanced PCE system, make sure to place each private node into the correct private network. A PC that represents the private node in the alternate private network also has to be provisioned.This PC is used for the alternate network to reach this switch in its home network.

Basic PCE Provisioning Roadmap

 

Note

The one-to-one mapping between private nodes and public gateways for TCAP queries from a public network is an optional feature and is declared in the public gateway attributes (refer to Configuring Public Gateways). This is a rare deployment; therefore, before you start this provisioning, contact Customer Support.

No TID mappings are performed for GTT tunnel PC destinations. When declaring the Point Code List, you must also specify the NA that you want to send traffic to. This information is used to cross the network boundary (see the following figure). For more information about configuring NAs, refer to the appropriate section in the SS7 Application Guide 1
