2.3Line Configuration

While you must share the same Line 1 telephone number at all the stations, you may choose to leave some lines unconnected at particular stations or to connect private or auxiliary lines to Lines 2, 3 or 4 at particular stations.

2.3.1COMMON

This is the factory setting for all lines. This setting assumes that the line is connected to the same telephone number at all stations.

2.3.2PRIVATE

Use this setting at any telephone that is connected to a different telephone number than the corresponding line at the other stations.

For example, you may connect your private telephone number to Line 3 at your station instead of connect- ing your station to the shared Line 3. In this example, you would set Line 3 at your station as PRIVATE.

2.3.3UNCONNECTED

Use this setting at any telephone that is not physically connected to all of its lines. For example, you may install a 2740 4-line telephone in a room that is currently wired for only lines 1, 2 and 3. In this example, you would set Line 4 at this station as UNCONNECTED.
