Tele-Communication (Telecom) Terms Glossary and Dictionary
Polling
Polling is an access method in which a primary network device inquires, in an orderly fashion, whether secondaries have data to transmit. The inquiry occurs in the form of a message to each secondary that gives the secondary the right to transmit. In telecommunications, polling is a long distance carrier access method in which a non-local call is carried by the long distance carrier via a dedicated trunk facility for either the first or last part of the call's journey, and on the carrier's network for the middle part of the journey.
