3.2PBX PARAMETERS AND PORT SETTINGS

3.2.1General Guidelines and Definitions

Optimal performance of the VPS/PBX system relies on proper VPS programming. There are 3 categories of hardware settings: RS-232C, Port Settings, and PBX Interface Parameters. Entering a number sets some of the parameters, while others use sequence codes.

3.2.2RS-232C Settings

•Baud Rate (300 - 38400): Specifies the bits-per-second (the speed at which the data is transferred).

•Word Bit Length (7 - 8): Defines the number of bits in each byte or character.

•Parity (N, O, E): Specifies the parity used for error detection.

•Stop Bit Length (1 - 2): Specifies the number of bits used to signify the end of the byte.

•Default: 9600, 8, N, 1

3.2.3Port Settings

There is no need to change these in a typical installation. Only change these parameters when using a CO (central office) line directly to the KX-TVS50/80. Each port on the VPS should be matched to the type of signaling the PBX expects. If you need to change these settings, refer to the PBX manual or customer support office to get the correct values for these settings.

• Flash Time—100, 300, 600, 900 ms:

The minimum amount of time that the PBX requires to recognize a hookswitch flash. Choose the amount that is equal to or greater than the PBX's setting.

• CPC Signal (Calling Party Control Signal)—NONE, 6.5, 150, 300, 450, 600 ms: The amount 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—1 - 8 s:

The amount of time that the line is temporarily unavailable after a call has ended.

• Dial Mode—DTMF, Pulse 10 pps, Pulse 20 pps:

The type of signaling the PBX single line port expects to receive. (pps = pulses per second)
