| UNIT 4: PROGRAMMING - LESSON 3: SYSTEM PROGRAMMING BY PC CO & Incoming Call menu Read pages 449 through 453 in the KX-TAW848 User Manual CO Line Settings The CO and Incoming Call Menu is used to set a variety of Central Office Line settings. The CO Line Settings Menu allows each line to have a name assigned to it. The corresponding name will be displayed on the proprietary display telephones when a call is received and the Caller ID feature is not utilized. Each line can be set into one of 64 trunk groups from within this menu. DIL Table & Port Settings Direct In Line (DIL) is the method of distributing incoming CO line calls to one or more extensions. Incoming Call Distribution Groups must be used when the customer application requires incoming CO Lines to ring at multiple extensions. If a Central Office Line needs to ring at only one extension, that extension number can be entered directly as the DIL destination. A separate destination can be set for each CO Line and time mode (day/lunch/break/night). When Calling Line Identification (CLI) distribution is utilized, it will override the DIL destination that has been set for the CO Line. Miscellaneous The Intercept Routing feature can be used for situations when the destination of an incoming CO line call is unavailable, or when there is no destination entered. You can choose to enable or disable the Intercept Routing capability when the DIL destination is busy or is in Do-Not-Disturb mode. You can also select whether calls should be redirected to the operator extension if a DIL destination is not set for a CO Line. By default the KX-TAW848 Main Unit does not have an entry set in the DIL Destination for any CO Line. This is why calls are redirected to the destination set as the operator (extension 101).
