îš„ Hook thresholds
îš„ Ringing generation and detection parameters
This means, for example, that changing impedance matching or hybrid balance doesn't
require hardware modifications, so that a single device is able to meet requirements for
different markets. The digital design of the filters and gain stages also ensures high
reliability, no drifts (over temperature or time) and simple variations between different line
types.
In future software releases, it is to be expanded to consist of different sets of line
parameters, which can be selected in the ini file, for each port.
Note:
To configure the FXO coefficients, use the parameter CountryCoefficients
(described in Analog Telephony Parameters).
8.5 User Information File
The User Information file is a text file that maps PBX extensions connected to the device to
global IP numbers. In this context, a global IP phone number (alphanumerical) serves as a
routing identifier for calls in the 'IP world'. The PBX extension uses this mapping to emulate
the behavior of an IP phone.
Note: The mapping mechanism is disabled by default and must be activated using
the parameter EnableUserInfoUsage (refer to ''Advanced Parameters'' on
page 112).
The maximum size of the file is 10,800 bytes. Each line in the file represents a mapping rule
of a single PBX extension. Up to 100 rules can be configured. Each line includes five items
separated with commas. The items are described in the table below:
