Inbound way parameters (to PBX)
Ring pulse time [ms] – this parameter sets the minimum time of the ring
signal presence needed for ring detection. If the ring time is shorter than the
preset value, ringing will be ignored.
Ring pulse treshold [V] – this parameter sets the minimum ring voltage level
needed for ring detection. If the ring voltage level is lower than the preset value,
ringing will be ignored.
Ring pattern time [ms] – this parameter sets the minimum period of time for
alerting detection.
CLI reception mode – the parameter defines the preferred CLIP (Calling Line
Identification Presentation) reception type. Choose
, or . DTMF FSK none
CLI reception timeout [ms] – the parameter sets the CLI detection timeout as
counted from the end of the first ring. This option is active only if the
or DTMF
reception mode has been selected. FSK
Polarity timeout [ms] – the parameter sets the reverse polarity timeout. This
option is active only if the
item has been selected for this Reverse polarity
virtual port.
Call reject timeout [ms] – if the PBX needs to reject an incoming CO call, it
has to pick up and hang up. Use this parameter to define the timeout for this
action. If the action is too short, the other party will not recognise termination.
Expert
Chipset
Chipset Type – this parameters determines the type of the chipset used. The
SILABS_SI350 chipset is only supported at present.
Chipset Config – activates one of the chipset configurations created.
New config – helps create a new configuration for the selected chipset type.
Specific Chipset Config
Name – sets the chipset type whose configuration is being set in the section.
Do not change the above mentioned parameters unless absolutely
necessary.
DCTerm – sets the DC termination parameters (ringing voltage, minimum
current, impedance). Hexadecimal values are used.
DAA Ctrl 5 – sets further parameters for analogue line matching (on/off-hook
rate, low pass filter). Hexadecimal values are used.
ACIM – helps set the proper impedance. Hexadecimal values are used.
Tx Gain – sets the transmit gain.
Rx Gain – sets the receive gain.
Refer to pages 78 to 81 of the User Manual for more details on the
parameters.
The table below includes the ACIM settings including meanings.
