You can use any of the ten stations (Ext. 0, and 1-9) to make and receive a
call with any line from LINE 1, LINE 2, LINE 3, or LINE 4, according to your
preference and need.
Before you make or receive a call at IS6100 Headsets or AT&T model TL80133

NOTE: If your workplace is using three-line wall jacks, you must first split the lines into 3 single-
lines to be connected to L1/2, L2, and L3/4 ports respectively, or a two-line plus a single line to
be connected to L1/2 and L3/4 ports respectively. Make sure there is no more than total of 4
lines connect to the L1/2, L2, L3/4, and L4 ports; otherwise, the lines cannot function normally.
