GSM or Global System for Mobile Communications refers to
a comprehensive digital network for the operation of all
aspects of a mobile telephone system.
Homes passed refers to households where a particular
technology (e.g. fibre or coax) has been rolled out, enabling
the reception of services associated with that technology.
The number of homes passed constitutes the sum of actual

Interconnection refers to the provision of access or
availability of facilities or services for another provider for

provided by another provider.

services in a modern and fully effective telecommunications
network of the same size as the SMP operator’s network.
