Matrix VISIONPRO System Manual 37
CHAPTER 5
Configuring Stations
Station configuration takes into account the following parameters,
• “Station Parameters”
• “Station Groups”
Station Parameters
Station Parameters include configuration of the following,
• CLIP Type: VISIONPRO provides a facility to detect the calling number and present it to the station. This is
known as Calling Line Identification and Presentation (CLIP). For this feature to work, the telephone
instrument connected to the station port must support CLIP.
VISIONPRO supports 3 signaling protocols to represent CLI on the port: DTMF, FSK-V.23, and FSK-
BellCore. Select the appropriate signaling protocol.
If you want to disable CLI on a port, select 'None'.
• Flash Timer: In Pulse Dialing, codes are dialed in pulses. A Flash key is generally used to dial this code.
Flash is dialed to break the loop current for a certain duration that can range from 70ms to 900ms. Flash
Timer defines this time period for which the loop current breaks.
If this break time of station current loop is of optimum level, VISIONPRO senses it rightly as a flash. But, if
the time is more, it can be wrongly interpreted as disconnection. On the other hand, if the flash timer is set
to a higher value, a genuine disconnection will take longer time.
You have to configure the station flash timer with a higher value than the flash timer used by the telephone
connected to it.
• Digit Padding: Certain telephone instruments do not display the DTMF CLI information if the number of
digit(s) received are less than a particular count. To take care of it, the length of the incoming number is
adjusted by padding digits.
Digit Padding works only when CLIP Type is selected as DTMF.
• AC Impedance: The SLIC used with each SLT port provides a facility to adjust the AC impedance of the
SLT port with the communication equipment connected to it.
