xDSL Coverage Maps (GIS/ JPG files)

xDSL providers have a need to understand the effective coverage territory of each DSLAM-equipped exchange.  Here we distinguish between PSTN coverage (notionally the whole exchange area) and the respective portions where ADSL/ ADSL2 services can be provided.

The coverage maps:
(a) Are offered as a service, for instance if a client needs coverage maps for 50 specific Exchange Service Areas, or all for a given State, Callpoint would create these and deliver as a set of GIS/ JPG files.  Clients need licensed access to Telstra exchange data, which we can facilitate

(b) Alternately, Callpoint AQ Pro® customers that have ordered the xDSL Coverage Wizard option can create these maps on their own

Either way, clients would obtain a set of ADSL, ADSL2 and "Distance Too Far" polygons for each required ESA.  Once these polygons have been created, geospatial techniques can be used to quantify numbers of included customers, extract company details etc.

Keep in mind that the simple "circular region" approach below, while easy to understand, does not reflect the reality of copper distribution from an exchange.  Simply, copper loops do not radiate in straight lines from an exchange.  More representative approaches include:
(i) Shortest walking distance (shortest path capability) within AQ Pro
(ii) Make use of Telstra copper cable loop length data to create Callpoint's "squiggly" equidistant polygons.

Note:

1. Subtleties apply in the case of multiple sub-exchanges within an ESA

2. Shaded regions below:
   - Red, being Large Pair Gain Systems (LPGS) e.g. Remote Integrated Multiplexers (RIMs), CMUX, RCMs that were not Telstra DSL-enabled as of production date
   - Green, being LPGS that were DSL-enabled as of production date

3. Coloured dots below:
   - Yellow, geocoded businesses
   - Purple, geocoded residences
   - Pink, GNAF (underneath the above two layers)

4. Callpoint has created large format coverage maps using digital street overlays that have been popular amongst telco sales staff.  Please contact us for further details.
