Provider Configuration
‘Location Area’ coverage is provided by a variety of companies in many countries. The
provider giving coverage within an area is made known to and displayed on the handset.
Each country is assigned a 3-digit identifier code, or codes, and each company authorized to
give GSM coverage is given a 2-digit identifier code. Therefore, the PMX system allows
‘providers’ to be added so they can be allocated to individual location areas (see section on
location areas).
In most cases PMX systems will use the 2-digit identifier allocated to PMN by Ofcom and this
will be the only provider configured on the system. As shown below, this will normally be set
to code 19 in country 234. In cases where PMN provide coverage on behalf of another mobile
operator, the other operator’s code may be entered. For demonstration equipment, code 01
and country 001 may be used as these are development codes.
Click on the ‘Providers’ icon to be presented with the providers list, then click on ‘Add
Provider’ to enter details of the new provider.
Once added to the system, a provider may be edited but not deleted.
