Network Model gets more and more complex

Network Model gets more and more complex …Network Model gets more and more complex …

The initial Goal was the management of an up-to-date OSP and ISP Inventory:

Traditional model for Copper Cables with Line of Counts as a methodTraditional model for Copper Cables with Line of Counts as a method of identifying end-to-end routes within a copper networkPNI fits this model adding many validations at LOC level to ensure data consistencyyAll three Cases uses PNI network model with very few customizations

The network is “alive” and LOCs change dynamically due to:

Changes of network topology by introducing new technologiesRenaming networksCustomer TransfersElimination of cross connectorsOthersOthers

Therefore:LOC is a logical entity and NOT suitable to relate Service records to it !Service records should be assigned to an physical network

Insync in order to manage Service Information in external databases


PNI creates routes “on the fly” using network traces

Network is traced from Serving Port to RME Port in order to determine the route and all involved physical resources ¡TAKES TIME! Please wait … (experiences showed up to 7 minutes to determine suitable routes)

ThereforeThereforePre-configured relationships RME Port – Serving Port need to be managed !



Bearers represent the relationship between start and end point of the network

A record that relates Serving Ports to RME Ports and the existing route between both pointsroute between both points

Bearers are constructed at engineering timeMore than one possible route may existMore than one possible route may existPartial Bearers may exist when network have x-boxes

Bearers are preconfigured routesp gThey speed up the feasibility response

Bearers are non-permanent because routes are NOT!

Therefore:Services should NOT be related to Bearers !



Service Assignment Process requires management of status information at port level

Spare, Connected, Pending, In Service, Disconnected, Reserved, CEA

Network Engineering and Maintenance ProcessNetwork Engineering and Maintenance Process requires management of physical status at port and pair level

Faulty, others

Therefore:Therefore:Service Assignment Process needs to take care of port and pair status !

Finding the Serving Terminal

Finding the Serving Terminal …Finding the Serving Terminal …

Access to network in PNI / CPAM is given by the relationship between Address and Serving Terminal

Quality of available base maps is the Main Concern for companies in Latin America

Different solutions were implemented:Pre-Relationship at Engineering TimeFull Address Data No Pre-Relationship By RadiusOnly Street Segments No Pre-Relationship By Coverage

Finding the Serving Terminal …Finding the Serving Terminal …PNI Standard Functionality

Pre-Relationship at Engineering TimeBase map with lots, parcels and addresses as point objects Manual selection of addresses that are related to a copper terminalUseful to model drops and “Connect-Thru’s”Does not represent businessDoes not represent business reality in most of south American countries

In some cases it is used to model Copper Terminals installed in buildings or commercial places which

Full Address Data No Pre-Relationship By Radius

Disadvantage:“Radius” gives the shortest gdistance from address to serving terminals but straight drop installation is not always possible due to

Example 2 - Integration using Insync and External DatabaseWeblogic

Use of standard messaging services and Java classes (proven and well

External DatabaseHigh customization of PNI to include business rules and add pair managment (LOC,(proven and well

documented)Only XML parsing was customized

add pair managment (LOC, Ripple, Throw, etc.)GIS and Service Assignment are separated

Concurrency and transaction managementEasy to maintain in future

Future maintenance requires great efforts to update the codeA hit t d t iArchitecture requires high

availability of GIS environment

Architecture does not require high availability of GIS



Benefits on both examples…Reduction of Feasibility Response Time

48 h t f t f d48 hours to fragments of seconds

Ability to respond feasibility, reserve and assign resources d i t tt tiduring customer attention process

Less changes in customer’s decisions to acquire a service Sales Process can be fulfilled with only one customer contactSales Process can be provided Online and without sales force involved

Seamless process generates and maintains higher data quality and integrity

More reliable data for Service ProvisioningOptimized use of available network resources



Other savings …Less GIS workstations for same number of feasibility requests o more requests with the same number of GIS workstationso more requests with the same number of GIS workstations

Less data maintenance efforts

Reduced fault repair times due to reliable data which leads to accurate fault correlation and effective field work

Increased engineering planning efficiency

Reduced re-work through integrated and accurate inventoryReduced re work through integrated and accurate inventory

Improved operations efficiency through integrated engineering and provisioning system views
