ECOTEL 3G 16.1. Revised: 2011.

ECOTELs can generate charge information but cannot transmit received charges from the public or corporate net-
works to the attached PBX. Charge impulses from the PSTN can cause interferences on the established connection
and must be deactivated. Charge simulation on the ECOTEL is achieved using variables, which ensure a great de-
gree of flexibility for the implementation of many different charge models including:

Charge units per time unit

Flat rate (initial charge without time interval)

Initial charge plus time interval

Initial charge plus time interval after delay

Time interval and/or flat rate

Initial toll-free period with retroactive charge generation afterwards
In this chapter, unit means that charge information is transmitted as a whole-numbered value, and currency
means that the charge information is sent as a currency amount (e.g.
EUR 3.45
). The charge impulse generation
options can be set for each mapping by adding charge-specific arguments to the
MapAll
commands as shown
below. The use of each variable is explained in Table 10.1.
MapAllsrc=dst time start/wait
The maximum supported number of units per connection is 32767 units.
Additional adjustments may be made to allow for the implementation of new charge models.

When charge information is sent as Currency, values can be expressed in thousandths for greater precision
in charge calculation.
For the internal Layer 3 protocols on ECOTEL GSM BRIs, charges can be specified to the third decimal place
(thousandth) using the
/Value
option (Example:
/Value:1.056
). In this fashion, charges can be gener-
ated for units of currency requiring accuracy to the third decimal place or for fractions such as tenths of a cent.
Table 10.1 Charge Variables
Variable Purpose
time Determines the length of each time interval (how long each unit lasts). The value is entered in
seconds and hundredths or thousandths of a second (the maximum value accepted is 655.35
seconds, 65.535 if thousandths are entered). If time is set to zero or not present, no charges
are generated.
start Optional. Sets the initial unit level. Enter a value between 0 and 127 whole units. If you want
to use a flat rate, set the desired number of units here and set the wait to 255 to turn off the
time interval.
wait Optional. Determines the delay after which charge generation begins. Once this time has
elapsed, charge impulses are sent in the interval determined with time. Enter a value between
0 and 254 seconds. 255 deactivates the charge pulse. In this case, the time variable is ignored.
