5.2 PBX Settings for Inband Integration
5.2.1 General Guidelines and Definitions
In order for the VPS and PBX to communicate properly, certain settings of both the VPS and PBX should be
set to the same values.
Programming procedures and availability may vary by PBX model. Consult your dealer for more
information.
5.2.2 Global Parameters
Global parameters are hardware settings that affect integration with the PBX. There is no need to change these
settings in a typical installation. Only change these parameters when connecting the VPS to a PBX other than
a KX-T series PBX.
Each port on the VPS should match the type of signaling the PBX expects. If you need to change these settings
for the VPS, refer to "Global Parameters" in 2.6 Hardware (H/W) Settings in the Programming Manual, and
refer also to the documentation included with the PBX.
• Flash Time
The minimum length of time that the PBX requires to recognize a hookswitch flash/recall. Select an amount
that is equal to or greater than the PBX’s setting.
• CPC Signal (Calling Party Control Signal)
The length of time allowed for the short break in loop current that is used to indicate that the caller has
hung up; usually set to None, since most PBXs do not provide this signal to single line ports. If choosing
a setting other than None, use an amount equal to or less than the PBX or telephone company provided
CPC signal.
• Disconnect Time
The length of time that the line is temporarily unavailable after a call has ended.
• Delay After Dialing Before Analysis
The length of time between the end of a call and the start of Call Progress Tone detection when an outgoing
call is dialed.
• Maximum Time to Wait for Dial Tone
The length of time that the VPS must wait for dial tone detection.
• Dial Start Mode
Specifies whether to detect dial tone or wait the specified time in Offhook Delay when an outgoing call is
dialed.
• Offhook Delay
The length of delay time when Offhook Delay is selected in Dial Start Mode.
• Delay After Dialing Before On-hook
The length of time that the VPS waits for an answer when an outgoing call is dialed. If the time period
expires with no answer, the VPS disconnects the call.
• DTMF Cut Length
The length of time for DTMF to be deleted when it is detected while in recording.
• Minimum Message Length
Specifies the minimum message recording length. Messages shorter than the specified minimum recording
length are discarded from the mailbox.
• Call Progress Tone Detection for Inband Mode
Specifies whether to detect Call Progress Tone.
