132 General System featuresEnterprise Edge Feature Programming Telephone Guide P0908510 Issue 01Usually, only the lines that are appropriate for a particular person appear at thatperson’s telephone. When a line is assigned to a telephone it is automatically givena line button on that telephone, if a button is available. The M7100 telephone hasno line buttons for its lines.Calls on lines that ring but do not appear at a telephone are presented at an intercombutton.You may be able to answer a call on a line that does not appear or ring at yourtelephone. To pick up such a call, use Call Pickup, Call Park, or Trunk Answer.A telephone may have buttons assigned for lines 001 to 003, but have only lines 001and 002 programmed to ring as well. An incoming call on any of the three linescauses a line button indicator to flash, and the telephone can be used to answer thecall. This is especially useful for people who monitor other telephone lines, butwant only their own lines to ring.Target lineA target line is used to route a call directly to a particular telephone or group oftelephones. Target lines are used only for incoming calls. A single incoming linemay provide connections to several different target lines. This allows each personor department in the office to have their own number without having a separateexternal line for each number.Line poolsA line pool allows each telephone access to external lines from a group (or pool) ofexternal lines. You can access such lines by pressing an intercom button andentering a line pool access code or by pressing a memory button programmed withthe line pool feature code and a line pool access code.Overflow call routingIf a call comes in for a target line that is busy, Enterprise Edge routes the call to theprime telephone for that target line. If there is no prime telephone assigned to thetarget line or if a call cannot be directed to a target line, the call goes to the primetelephone for the external line used.
