gales OraQcn or the MOun 62lC States Telephone and Telegraph Company of 0 rehabilitation of central office equipment consist. ing of the installation of some of the most modern equipment and features in telephony.
 Machine Ringing: The phrase Central, ring them again; I know there is some one there" will be forgotten by Nogales telephone users. Failure to get the called for number can occur only when there is no one there to answer the telephone or when the line is out of order.
 As soon as connection is es tablished with @ called for nun Der the operator will depress a key which starts mechanical ringing apparatus in that par tlcular connection. This will cause an intermittent ringing, at five second intervals, of the call ed partys telephone and will continue, without further atten- ] tion of the operator either the l called party answer or the call iheS pat " hdhAS up. o 8FOl0 the possibility of the operator failing to properly start the 1 ringing apparatus, a signal light is so arranged that it can be ex ting uished only when the ring ing is properly started
 So that the calling party may know what is being done to com | plete bis call, 0 reduced ringing current is reverted to his end of the connection, giving him an audible signal each time that the called telephone is rung.
 Results: For the calling sub scriber. Automatic indication that the called party's phone is being runR. Cause the called party to answer sooner.
 For the operator: Relieve her of supervising the answering oi the called party. Relieve her O! resiRning.
 Keyless listening and secrer service: Have you at times hesitated in using your tele phone as freely as you would liked to have, because yor thought that possibly the "cen tral" might be listening?
 The listening key will be ele minated and the association o loperators telephone set to th' connecting cords will be auto matic; connected when the an swering plug is inserted and dis connected when the calling plus is inserted in the called for line While the connection, is up, in [ terference by an operator listen ing or by double connection will be impossible.
 This method will reduce th operators time per call and in sure the subscriber of 3non inter fering service. ' -R~
 Instantaneous' Diseonnect:- that interval of time betweel when a party hung up and th' connection was taken down, tn, line would test busy even thougl the line was not in use at tn time. During very busy period when the connections cannot b. taken down immediately, thi will be the cause of numerou busy reports. This undesirabl feature will be remedied so tha the lines will test idle as soon g. both parties to conversation have hung up, even though tn connecting cords have not beel taken down.
 Instantaneous Recall: The ol' method of flashing" to attrac the operators. attention. whel you have completed a call ant wish to immediately place an other one, will be eliminated One flash" or depression of th, receiver hook will bring th' signal in as new call, the an sweriug of which will not b. limited to the operator taking the first call, but can be answer ed by any operator at the switch board.
