AND 3.3 - Living DocumentationAND 3.3 - Living Documentation
Typical users of network documentationTypical users of network documentation
Cable and telecommunication operators Network planners Service staff & network technicians Hotline support Customer helpdesk Marketing department
Documentation methods Documentation methods
PaperWare Lode Data (DOS-based solution)
Solutions with external calculation tools e.g. Excel AutoCAD Smallworld (proprietary GIS)
Open GIS Integrated documentation, planning
and engineering solutions in a singleCAD solution AND (Advanced Network Design)
AND - an evolution since 1988 AND - an evolution since 1988
Solution for design, measurement, verification & documentation of bi-directional networks
In 3rd generation Complete development
by CDS AND product family
AND Smart Server GIS plug-in Fiber Management Inventory Management Network Monitoring System PocketVision: PDA-based on-site tools
AND - Good planning saves time & costsAND - Good planning saves time & costs
Strategic investment planning Improves purchasing process
Keeps stocks to a minimum Reduces wastage
Build according to design instead of costly trial-by-error Reduces site visits and
unnecessary installations Reduces manpower costs
AND - Good planning saves AND - Good planning saves time & costs time & costs (2)(2)
Reduce time to complete the network build Earlier ready-for-operation status Shorter investment period and faster ROI
Reduce maintenance costs Avoid unnecessary site visits to replace or adjust components
AND in a nutshell …AND in a nutshell …
An easy to use reliable single-platform solution for Parallel network documentation, planning and engineering Accurate network simulation from headend to each outlet Bill of material, ordering and commissioning support Installation, verification and revision support
Schematic and geo-schematic formats with logical network structure and GIS options
Full server support Powerful SQL queries for
complete database Component selection from
extensive libraries
AND in a nutshell … AND in a nutshell … (2)(2)
Migration of available data Scans, AutoCAD, Lode Data,
Smallworld, Multicom etc. Comfortable access to data
User-friendly applications with fast response times
Web interface Offline information PDA interface for on-site planners and technicians - data via
GSM, GPRS, UMTS etc. Network monitoring with real time interface to element
managers CMTS + Cable modems HMTS + Transponders
Network engineering for new builds & upgradesNetwork engineering for new builds & upgrades
Network checks to test component harmony Simulation of network
Viability of network confirmed before build begins Calculation of entire spectrum
for both upstream & downstream RF levels and attenuation Distortion products & ingress C/N CTB, CSO
Optical calculations fully integrated BER, MER
Network verificationNetwork verification
AND interfaces to network measurement devices PT1, Acterna, KWS etc.
Compare calculated and actual measurements at self-designated test points Graphical representation of
measurements and calculations Allows network supervision &
inspection Quality control during all stages
of network build & maintenance Protects your investment
Manages data from measurement devices incl. history
Maintenance with intelligent documentationMaintenance with intelligent documentation
Geo-referenced infrastructure and components Detailed component information Information retrieval for all network sections incl. full
history support Network history allows
comparison of status, BOM, etc. NIS – logical network
Which objects are connected to which nodes and hubs
Which services are connected to given amplifiers
AND takes care of your inventoryAND takes care of your inventory
Inventory Management helps answer many questions: WHAT components are installed? WHERE are the components installed? WHEN were the components installed?
(and when do they need replacing)? WHICH services are affected by given
components Optimize maintenance costs
Fault recognition and detection Component maintenance and
replacement information
AND manages your fiber AND manages your fiber
Installation route Amount of fiber Available capacity Services provided on
given fiber Signal path tracing Fiber to the Home* Ethernet to the Home*

Disadvantages of AutoCAD solutionsDisadvantages of AutoCAD solutions
Requires separate calculation tool Manual assignment of attributes to graphical elements Inefficient work process Risk to data integrity
Doesn’t support multi-level worksheets Information overload – lack of clarity
When editing others are blocked from working Compatibility issues with new versions of AutoCAD
Risk of product halt e.g. Voloview Risk of change to interfaces e.g. AutoCAD 14 / ESRI Risk to change in license politics
AND advantagesAND advantages
Documentation incorporating maps and networks in a redundant-free system All network and component data stored together with maps in
a single database High integrity data management Parallel activities reduce workload and manpower costs Rapid retrieval of data for all sections of network regardless of
location of user Supports multi-level worksheets
Promotes clutter-free design and documentation using through-network calculations
All sections of network interconnected Project hierarchical structure
Living documentation is the motivation behind accurate documentation Documentation with geo-referencing Engineering, calculation and verification functions Bill of material with cost and
manpower calculations Network Inventory management Fiber management Signal path tracing Logical network structures Network monitoring PDA-based solutions

Consequences of poor planning …Consequences of poor planning …
Murphy's Law - if it can go wrong it will … Bad component purchases
Increases costs Unnecessary stocks
Unreliable networks Costly maintenance
Unusable for multimedia services Loss of potential income
Increased churn rate Loss of customer base Loss of income
