Clocking
Under clocking (formerly known as Telephone timing ) is understood in telecommunications at time rates sharing the connection time in certain time intervals as the basis for calculating the charges for end users.
Notation
The clock is usually specified using two numbers separated by a slash. The first number stands for the duration of the first bar in seconds and the second for the duration of all subsequent bars. "60/10 clocking" means that the first 60 seconds of a connection are always fully charged, even if the connection lasts less than 60 seconds; after that, it is billed in 10-second steps.
The shorter the interval before or after the slash, the more precisely the connections are billed, which is usually more cost-effective for the customer (billing to the second is optimal). An example: In the case of 60/60 frequency, more rarely also specified as "1/1 minute clock", a connection of two minutes and five seconds costs the price for a full three minutes; on the other hand, 60/1 only calculates the actual connection time of two minutes plus 5 seconds.
Frequent clocks are 60/1, 60/10 and 10/10. In the open call-by-call you will also find the clocks 300/300, 240/240, 60/60, 60/1, 30/30 and 1/1.
Most providers bill every 60/60 minutes.
Statistical comparisons
Statistical evaluations of real telephone bills as well as calculations with the help of the gamma distribution model resulted in the following approximate guide values: If one takes a tariff with a rate of 1/1 as the standard (0% surcharge), then a rate with a rate of 60/1 would be about one mean an increased invoice amount of around 20%. A 60/10 tariff would in practice be around 30% more expensive than the 1/1 tariff. The tariff model 60/60, however, would in practice be around 50% more expensive than the tariff variant 1/1.
Billing of volume tariffs
When data is transferred according to volume tariffs , the transfer volume used is divided into blocks. With a 100/10 kbyte cycle, for example, at least 100 kbyte usage per connection is billed, and the additional volume is billed in increments of 10 kbyte. A connection is terminated by switching off the mobile device or by the operator after a certain period of time without any activity or reception. Then a new connection is established and charged. Common frequencies are 10/10 (until 2015 e.g. many cell phone discounters and resellers in the E-Plus network) and 100/100 (cell phone discounters and resellers in the O2 network). Volume tariffs are no longer sold in the Vodafone and Telekom networks (as of April 2015).
