INDIRECT ACCESS OPERATOR
Indirect access operators use BT's infrastructure from a customer's premises to the exchange to provide their own services. Services from these providers are accessed by dialling a prefix number, by routing through a 'smartbox' or router which automatically dials the prefix, or by registering for carrier pre-selection.

INTEROPERABILITY
The ability of different telecoms networks and/or devices to work together to provide a seamless service for users.

INTRANET
A closed data network using Internet protocols, used by companies and organisations to make information available to their employees.

ISVR OPERATOR
ISVR operators offer cheap international calls and operate under an International Simple Voice Resale (ISVR) licence. ISVR involves the conveyance of calls via a public network (for example BT's) in one country, over an international private leased circuit and then via a public network in another country. ISVR operators are able to reduce their costs because they are set up to use international capacity on a long term basis and use cost-saving processes that maximise the number of calls carried on a given link between two countries.
