Connexions analogiques
Amplification d’émission (-6 à +6 dB)
The transmission amplification specifies the number of decibels by which
the PBX reduces or increases all outgoing audio signals.
This is necessary if the recipient considers the audio signals to be too loud
or too quiet (e.g. the volume at which speech is output to an external call
partner).
Compensation de l’écho
This compensates for local echoes and reverberation effects.
Affectation de ligne
Attente de tonalité
Before the PBX dials a phone number it checks whether a dial tone
has been sent from the public exchange. It starts dialling as soon as it
detects a dial tone for 200 milliseconds
This function prevents the PBX dialling the wrong number by starting dialling
too early if the public exchange takes too long to play the external dial tone
it generates.
Note:
Disable this setting if the dial tone cannot be sent clearly by the
public exchange and, as a result, cannot be identified by the PBX.
