4.2 CONNECTING THE VPS WITH THE PANASONIC KX-TA62490 Installation ManualPossible causes of the message: "APT Interface Connection is notEstablished"10. Start up completed.a) The Power Indicator light stops blinking when the start-up has been successful. (Thedelay varies according to the system’s condition.)b) "**ON LINE MODE**" is displayed.c) System prompt [>] is displayed on the screen. To enter system administration, PressENTER. All parameters can be set through the menu-driven program.11. Go to the System Administration Top Menu. Type [5] and Press ENTER, or Type [3] thenQSET and Press ENTER for Quick Setup and follow the Auto Configuration Instructions.CAUTIONWhen 2 VPSs are connected to the KX-TA624, the following 2 procedures shouldbe done to make the VPSs work correctly.1. Delete a mailbox in either VPS so that each extension has only ONEMAILBOX. After Auto Configuration has been executed, an extension hasa mailbox in both VPS1 and VPS2. However each extension can have amaximum of 1 mailbox in either VPS. To delete a mailbox, Type [D] (Delete)in the "Make (Make/Delete)" field (see "Step 4 Creating Mailboxes" in 5.1.3Starting the Quick Setup).The extension should assign a Voice Mail extension from the VPS whichcontains its mailbox as the destination for Call Forwarding and Voice MailTransfer. DO NOT assign a Voice Mail extension from the other VPS. Forexample, if jack 06 (extension 106) has its mailbox in the VPS1, assignextension 107 or 108 as the destination, not extension 115 or 116 (seediagram below).Table 4-3Cause ActionThe PBX is not a correct type. Since the VPS isconfigured to communicate with the default PBXtype (the KX-TD816/TD1232/TA1232 underDPT Integration), this message will alwaysappear when connecting to another type ofPBX.Connect a correct PBX and setthe PBX type by using QuickSetup (see Section 5CUSTOMIZING THESYSTEM).The cabling between the PBX extension portsand the VPS is not 4-wire or is improperlyconnected.Confirm the cabling isconnected as described inSection 2 INSTALLATION.The PBX is a correct type but does not have theproper software level to support APT/DPTIntegration.Contact National Parts Centerat 1-800-833-9626or use Inband Integration underhardware settings.The PBX is not programmed properly to supportAPT/DPT Integration.Do required integrationprogramming as described inthis chapter.
