This key may be pressed instead ofthe hookswitch.C.O. LINESLines from the telephone company are “C.O. lines.” Calls on these lines arereferred to as “outside calls.” These C.O. lines are accessed by dialing anaccess code. For example, dial 9 to get a local outside line or dial 800–8XXfor other line groups. Each line in the system is numbered beginning with701, and then 702, 703, etc. To get a specific line, dial its three digit line num-ber.
