 GIS Manager
 Lead a team of 7 GIS Professionals
 Tri-State - 14 years

GIS & Telecom Staff
 8 GIS Staff
 Centralized GIS located at HQ
 Diverse tasks – Electric Transmission, Generation, Telecom and Mining
 5 Telecom Engineers
 Sit at Tri-State HQ building
 Responsible for engineering and design of telecom network
 Primarily microwave and equipment
 1 Telecom Projects Coordinator
 Manages installation of fiber optic cables
 Manages 3rd party users of Tri-State’s telecom network
 Manages Tri-State’s use of 3rd party networks (excluding leased capacity)
 1 Leased Circuits Coordinator
 Manages leased capacity on carrier networks
 50+ Telecom Maintenance Techs
 Distributed across the 4 state region
 Manage installation and maintenance of all telecom assets and equipment

High Volume of Telecom Assets
 Grand Junction to Albuquerque:
 440 miles, 11 segments, 144 fibers per segment, 2 ports per segment =
approx 4800 fiber records.
 One OC-48 Grand Junction to Albuquerque
 11 segments, 48 STS’s per segment, 28 T1’s per STS, and 24 DS0’s per T1
= approx 355,000 circuit records.
 Adding 100 to 200 miles of fiber
per year
 Adding 150+ circuit requests
per year

Current System ~ CSMGMT
 Originally Access 95 Database with VBA Forms/Reports
 Converted to Oracle 9i Forms in 2004 (10g released in 2003)
 Tracked logical infrastructure of circuits including SONET
timeslots/channel designation
 Excel spreadsheet for fiber records

Business Drivers
 Current System Issues:
 Deprecated Oracle version (9iAS)
 Slow and not user friendly
 No GIS component
 Not scalable
 Missing needed features (trace circuits,
manage fiber routes, link to
documentation, track financial
information, etc.)

Proposed Solution
 Create a GIS database and web-based interface to:
 Identify, review, analyze, and update key attributes of the
telecom network
 Include collocation buildings, equipment
locations, fiber optic routes, microwave
radio systems, MAS radio systems,
USAT, and UHF radio systems
 Provide ability to track logical
provisioning with similar capabilities
as current home grown system to the
DS0 level
 Geospatial database with robust mapping
capabilities

Requirements ~ Larger Than Fiber
 Initially a new GIS telecom COTS software to satisfy fiber
management needs
 Leadership Approved New Circuit Management Solution
 Add customized software interface to COTS fiber software
 Migrate Telecom database
and fiber data to customized
GIS telecom software
 Tie telecom circuits
to GIS software
 Focus on expanding fiber routes

Final Solution
 Reviewed numerous software providers
 Interview & demo 4 leading COTS software vendors
 Selected ESRI/Schneider and Fiber Manager
 With a custom implementation for bandwidth mgmt by SSP

GIS-Based Telecom Asset Management
 Esri ArcGIS Manages Core Mapping

GIS-Based Telecom Asset Management
 Schneider Electric Fiber Manager Manages Connectivity & Assets

Fiber Manager
 Network Analysis and Tracing
 Connection Management
 Fiber Connectivity Traces
 Define circuit paths
 OTDR Trace

Fiber Manager – It’s Physical
 Connection Manager allows you to connect fiber, microwave, etc. to
a physical port on a device on each end
 No internal connectivity between device ports within a device
 Circuit Manager allows you to create a named physical path from
device to device
 Does a good job in tracking physical assets and connectivity

 Track master/header circuits that traverse through devices
 Custom Trace Linking Multiple Fiber Manager Physical Circuits
 Defines connectivity between internal device ports
 Establish bandwidth between end points

Creating Master Circuits
Start by selecting a single site feature on the
map. Click the Master Circuit button.

Select the starting port
which initiates an
outbound trace on the
connected line.
At the site on the other end of the trace, review
the inbound port and select an outbound port if
available/required.

The trace is visualized on the map

Once the trace is complete, enter information
about the master circuit and click Save.

Bandwidth Hierarchy
 Define a bandwidth hierarchy for each master circuit up
to an OC-192 (10 Gb/s)
 Allocate logical trunk circuits
(reserved bandwidth, ex. a full STS-1 or DS1)
 Provision logical tributary circuits
(committed bandwidth) down to a DS0
 Custom Two Point Trace Through Master Circuits

Bandwidth Hierarchy
 Allocate circuits within the master circuit hierarchy
 24 DS0s = 1 DS1
 Tributary Circuit
 Ex Hierarchy:
 Consuming the 1st Vir. Tributary
 Within the 13th OC-1 (trunk)
 Within an OC-3 (trunk)
 Within an OC-48 (master)
 OC048-024-12-03 :: Defines the Timeslot of the circuit

Provisioning a Logical Circuit
Provisioning is initiated from
the Tri-State toolbar.
Define the properties of the
logical circuit.
Choose the start and end sites.

Any eligible paths are shown. Selecting a path
shows the systems that are crossed.

For any systems included in
the path, the user must
provision the timeslot of each
logical circuit.
Here the user chooses:
The 8th DS0
in the 3rd VT
in the 1st STS
of the TSGT-C OC-3

When some circuits are
provisioned, the color
changes to orange.
When all circuits are
provisioned for the system,
the color changes to green.
Repeat for each system
crossed within the path.
The save button is then
activated.

Technical Benefits
What can we do with this level of detailed data?
 Recommend circuit provisioning based on available timeslots
 Track allocated bandwidth vs. capacity at all points on network
 Create a GIS heat map showing bottlenecks
 Drive capital planning for network expansion
 Poke the network at any point to see:
 Hierarchy of the master circuit(s)
 Which logical circuits are present
 The use of each logical circuit (down to the DS0)
 Result is a scalable system

Bandwidth vs. Capacity
Choose one or more systems to review.

Bandwidth vs. Capacity
The map zooms to the extent of the system, which is shown here in green. Note that:
 < 50% the system will be displayed in green
 50% to 75%, the system will be displayed in yellow
 75% to 90%, the system will be displayed in orange
 > 90%, the system will be displayed in red

Business Justifications
First . . .
“It has to be done!”
And second . . .
“It will save us time and money!”

Business Justifications
 Current system is not supported by Vendors
 No significant system upgrades over last 20 years
 Key personnel are nearing retirement gone!
 Growing number and complexity of assets
 $100M in Capital project over next 5 years
 Need for spatial analysis of assets
 Inefficient circuit design and fiber tracking process

Business Benefits
 Reduces time required to manage circuit/fiber
design and installation
 Replaces existing unsupported system with a
GIS based platform
 Consolidates several systems into one platform
(CSMgmt, Telecom Room Database, AutoCAD drawings, Excel
Spreadsheets, etc.)
 Standardizes work flow and processes

Business Benefits
 Eliminate a portion of drawing packages and
paper documentation
 Reduce time to troubleshoot and locate outages
 Greater data integrity and access for field mtnce
 Provide enhanced reporting functions
 Track 3rd Party usage of the telecom network
 Provides opportunity to roll to Linux
