Connections per circuit hour
Encyclopedia
In telecommunication
, the term connections per circuit hour (CCH) has the following meanings:
The magnitude of the CCH is an instantaneous value subject to change as a function of time
(i.e. from moment to moment), and is subject to study including load curve
and busy hour
as other measures of traffic are.

Telecommunication
Telecommunication is the transmission of information over significant distances to communicate. In earlier times, telecommunications involved the use of visual signals, such as beacons, smoke signals, semaphore telegraphs, signal flags, and optical heliographs, or audio messages via coded...
, the term connections per circuit hour (CCH) has the following meanings:
- A unit of teletraffic measurement expressed as the number of connections established at a switchingSwitchingLAN switching is a form of packet switching used in local area networks. Switching technologies are crucial to network design, as they allow traffic to be sent only where it is needed in most cases, using fast, hardware-based methods.- Layer 2 switching :...
