When used in conjunction with the pushbutton dial keypad, the indirect button shall be used to initiate intercom and telephone cal 1-S which are not otherwise accessible through a DA pushbutton. All DA accessible parties sh
25、all al so be accessible through use of -8- Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-the IA procedure. An indirect access shall be initiated by an ini tia1 operation of the IA pushbutton fol lowed by the appropriate address code entered on the
26、keypad. A self test of the position shall be provided and activated by an indirect access self test code. This feature shall execute test routines in the position processor to perform diagnostics verifying operational status of the position. Appropriate pass or fail indications shall be provided. In
27、 addition, a means for testing all indicator lights shall be included. A reconfigure enable function shall al so be provided which allows an operator to control the timing of the reconfiguration of his position. After system reconfi guration has been i ni ti ated by the supervi sor, the operator pos
28、ition shall receive a vi sual and audible indication that the position is ready for reconfiguration. However, reconfiguration can not occur until the operator executes an indirect access code on the SFM keypad. An audible indication shall then be received at the position indicating that position rec
29、onfiguration is complete. A self reconfiguration function shall also be provided which shall allow each operator to select not less than two of the pre-programmed position maps described in 3.3,2.3.1. The reconf iguration shall be i ni tiated by entering an indirect access code on the SFM keyboard.
30、No other positions shall be affected by this self reconfiguration. The access code shall be changeable. c. Call answer (CA) pushbutton. The cal 1 answer pushbutton shall provide the capabil i ty to answer all calls not directed to DA buttons and provide a visual indication. d. Hold (HLD) pushbutton.
31、 The hold pushbutton shall establ i sh a hold condi tion on al 1 intercom (IA) and telephone cal 1 S, except override cal 1 S, to enable the operator to answer or initiate another call without disconnecting the call on hold. It shall be possible to -establish a hold condition on multiple circuits at
32、 a position simultaneously. The indicator light of each circuit on hold shall wink. A connection shall be reestablished by depressing the button associated with a circuit on hold thereby removing the hold condi tion for that circuit. e. Release (RELI pushbutton. The release pushbutton shall disconne
33、ct the position from any existing intercom or telephone connection except an incoming override call. The release button shall have no status indicators. f. Headset/loudspeaker (HL) pushbutton. Successive operation of the HL- button shall direct the audi o routing of incoming intercom/tel ephone and
34、radio calls either to the headset or to the loudspeaker as chosen by the operator. g . Overri de headset/l oudspeaker (OHL) pushbutton. Successi ve depressions of the OhL pushbuttons shall direct the routing of incoming override cal 1 S either to the headset or the loudspeaker as .chosen by the oper
35、ator, unless the HL switch is in the speaker position. In this case, the HL switch shall govern the routing of incoming override cal 1 s. Al so provides a vi sual indication of an incoming override cal 1 . i. Programmable pushbuttons. Two programiable pushbuttons shall be provided on the SFM which m

It shall contain a dual set of tip-ri ng-sl eeve jacks for use with 6-wire headsetdhandsets equipped with a PJ-421 plug. The jacks shall occupy
42、 minimal space in a front-panel mounted module but shall be sufficiently separated to allow headsets and handsets to be easily inserted and removed without undue stress on the jackbox or headset/handset. One set of jacks shall be clearly designated for use by the operator and the other set shall be
43、clearly designated for monitoring, For clarification purposes, the operator pl ugged into the operator jacks wi 11 be referred to as the main operator while the operator plugged into the monitor jacks will be referred to as the monitor operator. a, Normal operating mode, In this mode, the main opera
44、tor shall be ab.1 e to communicate on intercom and telephone channel S without depressing hi S headset s PTT switch, To communicate on radio, the operator must depress the PTT switch or the positions footswi tch. The monitor operator will only be able to monitor all communications unless the followi
45、ng actions are taken. To communicate on intercom and telephone, the monitor operator must depress his headset/handsets PTT switch, To communicate on radio, the monitor operator must depress the PTT switch and the position S footswi tch. b, Split operation mode. If the Split Operation (SO) button on
46、the SFM is selected, the main operator shall have access to radio communications only, while the monitor operator shall have access to i ntercom/telephone communications and shall be able to hear radio communications except when intercom/telephone communications is in .progress. The monitor operator
47、 will not have the capabil i ty to comunicate over a radio channel while operating in the SO mode, c, Instructor mode, If the Instructor (INST) pushbutton on the SFM or DASM is selected, the monitor operator shall have pre-emptive capabil ities over the main operator regardless of whether the operat
48、or is transmitting on a radio, intercom or telephone channel , The monitor operator i ni tiates pre-emption by depressing the headset/handsets PTT switch.
