Telecom services now include fixed-network services (data retail, Internet retail, voice retail and wholesale) and mobile services.

Fixed-data services — Includes all dedicated/private line, packet and circuit-switched access services (for example, frame relay, asynchronous transfer mode, IP, Integrated Services Digital Network, DSL, multichannel multipoint distribution service (MMDS) and satellite) retail revenue. No differentiation is made between the type of traffic or application carried by these services. All types of transmissions — nonvoice data, image, video, fax, interactive services and even voice — can be carried by these services regardless of whether the source format is analog or digital. All revenue reflects service provider annualized retail revenue — paid for by the business and residential end user of the service; no wholesale or carrier-to-carrier revenue is included.

Fixed-voice services — This reflects retail voice service revenue for all services that are sold as such to end users and includes the provision of local and long-distance services related to voice (calling charges, line rental/subscription and connection fees are included in this category), enhanced voice services, data and fax transmission over the circuit-switched PSTN, and retail voice over IP revenue — paid for by the business and residential end user of the service; no wholesale or carrier-to-carrier revenue is included.

Mobile telecom services — Income from mobile telephone calls and mobile data usage (Short Message Service (SMS) and mobile data access) from all mobile operators in that regional market. Consumer charges are removed. Income from mobile telephone calling charges, mobile data access, SMS charges, line rental/subscription and connection fees are included in this category.

Wholesale/carrier services are not included as a component of business IT spending. Wholesale/carrier services reflect carrier revenue from carrier-to-carrier service transactions.
