3.2 PBX PARAMETERS AND PORT SETTINGSINTEGRATING THE VPS WITH PANASONIC KX-T PHONE SYSTEMS 433.2 PBX PARAMETERS AND PORT SETTINGS3.2.1 General Guidelines and DefinitionsOptimal performance of the VPS/PBX system relies on proper VPS programming. There are3 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.3.2.2 RS-232C Settings• Baud Rate (300 - 38400): Specifies the bits-per-second (the speed at which the data istransferred).• 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, 13.2.3 Port SettingsThere is no need to change these in a typical installation. Only change these parameters whenusing an outside (CO) line directly to the KX-TVP50. Each port on the VPS should be matchedto the type of signalling the PBX expects. If you need to change these settings, refer to the PBXmanual 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 recognise 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 indicatethat the caller has hung up; usually set to NONE, since most PBXs do not provide thissignal to single line ports. If choosing a setting other than NONE, use an amount equalto 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 signalling the PBX single line port expects to receive. (pps = pulses persecond)
