Abstract
A paging system (10) comprising a centrally located terminal (12) and a plurality of remote pager units (24) is disclosed wherein both automatic and manual acknowledge back signalling is provided. An appropriate acknowledge back signal by a called pager within a set interval indicates the message was duly received and understood which is so indicated to the initiating caller. Failure to respond within the set interval causes the pager unit to send back a negative response which is likewise so indi-cated to the initiating caller.

pagerfuser. upon being addressed (called), receive such address and is helshe in a position/condition to receive and understand the intended message to follow. For example, the paging receiver may be sitting on a desk by itself remote from the location of the 5 person or user. In this case, the pager itself, if turned on, is capable of receiving paging calls, but the pager user is not, because he or she is at some other location. Similarly, the paging receiver may be in a battery charger and likewise capable of receiving and in~lir:ltin~ an q.~tomqtir acknowledge-back signal, 10 but the user is not in a position to receive the intended message.
Further, the pager may be on the person of the user and capable of mom~-nt~rily receiving a signal and Ic~rldillg with an q~ m stic acknowledge-back signal, but moments later having the o " path degraded by a steel beam in an office building 15 or the like. Sending an intended message at that particular juncture would mean the same would simply be lost.
Accordingly, it will bc seen that nc,t~ h~ ling a page}'s capability of z~. ~u --~;c illy acknowledging back a response signal to a receive address call, there is indeed a good deal of 0 UI~ Y and, in some cases, confusion regarding the users ihili~y, and the paging system with such a~t~mq-ir acknowledge-back capability, in terms of what further response is expected from him/her as well as what time it is to bc effected.
Further, there is also some I lai.~ty at the central or base-site 2 5 location from where a page is trqncn~it~ d and particularly with respect to the origl- of the call regarding whether or not the pager user being called is ready and capable of receiving, or has receivod and ~ ood a particular IIA~ message.
Nul~ ': '' g the fact that an address was l-A~ d and 3 0 received by the pager being called and an a~ tic ?cknowledge-back signal being sent, the central station/telephone caller originating the call needs to know that a response has been effected by the pager user, whether it be an affi,l-,~.tilr., or a negative response. An "afrillllali r~, acknowledge" response 3 5 indicates the user has received the message and has duly ,o..~ a negative response indicates confirmation is lacking.

WO 90/10922 PCI~/US90~00613 - 5 - 29~6~1 The system 10 may include a paging controller console or terminal 12 which may receive incoming calls at a telephone input port 14 from, first, human callers utilizing conventional or standard ~ phf~ handset 16 or, secondly, from personal S cu~ ,.,t~ or video display terminals depicted at 18, or, thirdly, from page entry terminals as shown at reference 20.
Console terminal 12 will process the paging request, extract the ;Ip~ lial~ address from internal memory and activate the paging tral.c ni~t~r 22 to broadeast the intended 10 paging call, and which in tur~ is received by the a~",lu~.lial~
system pager for processing the information and alerting the paging receiver wearer or user. As will be ~ ' ~luod, the pagers of the system may be of tone only type, as depieted at 24a, a tone and voiee pager, as indicated at 24b or an ~ ie display 15 type, as shown at 24e. As I -~ previously, the system 10 may comprise different types of these .~ ,nced pagers intermixed within the system, or it may be populated by only a partieular type of pagers. But in any event, each of these pagers within system 10 is equipped tû respond with an ~ aek-2 0 baek signal upon being paged (ad.ll~,~scd) by the eentral basestation or l. allslllil~ur 22.
As well known, and as illllctr~ d in Figure 2, a terminal interfaee module 26 aeeepts ineoming ealls from a PABX or a publie s~viteh ~ p~ c network (PSTN) shown in dotted line at 25 28, whieh in turt~ -r~rcs with a standard t~l r'~ lr device 16, a personal COIll~..tl,- or video display terminal 18, and/or a page entry terminal (PET) 20. If the ineoming eall is from a standard tcl~,~h~r- unit, it is plu~,~,sse~ by the module interfaee 26 from an included DTMF deeoder (not shown) c ~ to input port 1 4A.
3 0 If the ineoming eall is from a VDT 18 or PET 20 an internal modem in the module interfaee effeets the proeessing as indieated at inputs 14b and 14d by the referenee "M".
As best seen in Figure 3, the terminal 12, in addition to one or more interfaee modules 26, further ineludes a eontroller 35 32, a synthesizer 34, a memory 36 and an aeknowledge back deeoder 38. With the ~Yreption of the aek-back decoder 38, the other referenced CGlllpO~lC..t parts functioned to ess~n~i~lly route WO go/10922 Pcr/US90/00613 2~45681 - 6 -., .
the incoming paging request at a port 14 on the input side to thc ~Ir ~ .- control ports 30 on the output side. Controller 32 serves as the "brain" of the system and includes ? ni~ ,uce~or ~not srecifirally shown), while the ~ .,.,. 34 generates the 5 sometimes required paging tones cQnctit~tin~ thc pagers address c~ntained within memory 36 along with other system parameters and relevant subscriber informq~ic~ The ack-back decoder 38 receives the various ack-back signals from the systems pagers which are utilized to determine the degree of ~,c fi~' ~ as to 10 whether a particular paging message was received and understood by the pager wearer, as will be described hereinafter.
In any event, terminal 12 along with ll~."i,...ilt~,. 22 and associate antenna 23 ctit-lt~ the base site or system side 13 of the pagirig system 10.
- The pager-side 15 of system 10 c~ ,.;c~s the paging receiver portion 50, the included ack-back encoder 58 and ~Ccociat~d antenna 54. A more detailed ~ ion of a system pager is shown in Figurc 4. In addition to the foregoing, the overall pager unit 24 furthèr includes an antenna switch 56, a 20 ~ JI. portion 52, a speaker 60, a display 62, if of the numeric or all.l.-..~,.... ~;~ type, and a latch 64 and manual button 66 coupled to the ack-back encoder-controller 58b and a manual response indicator 68. Indicator 68 may be an LCD segment or an LED displayed on the outer pager housing. Additionally, it ~nay 2 5 also include an audible 1._ ~ ' normally already a part of the pager unit.
In operation, incoming calls are accepted at the a~ ul~iatè input ports 14 and are sllbs~qllcntly ~-vcei.sed by the controller 32, which, say for example, has a call from a standard 3 o t~l~pho~e for a conventional tone and voicc page, generates the necessary tones for the intended pager as taken from memory 36.
These tones are outputted on the output control lines to lld~ l 22 and broadcast by the antenna 23. The address is received by page antenna 54 and is ~llùcess~d by the pager 35 receiver portion 50. Upon being decoded and l~,co~ d by address decoder 58a, an a~tom~tiC ack-back signal is generated and ~ d back to terminal 12 by pager transmitter portion wo ~10922 ~ sso/006l3 2~56~1 52, which is received and ~.oc~s~d by ack-back` decoder module 38. No action is required by the pager user for this sequence of mm mq~ic~lly reSpnntling and requires only that the pager 24 be turned on and receive the particular address signal.
S Upon receipt and processing of the all~omoti~ ack-back response from pager 24 by terminal 12, the intended message may then be IIA~ d to pager 24 in likc fashion. During the time for processing the message, and for a ~cdut~ ir.ed period thereafter, which concti~t~s a response interval, the pager 10 wearer may activate manual ~_' ~ 66 to generate a further and manual ack-back response. When received and ~.uc~ssed at the base-central site, it is illdicali~, of the condition that the page message was duly received and ulld~ ood by the intended pager wearer. Accordingly, the origin~in~ caller may be so advised by a 15 pre-programmed message stored in terminal 1 2.
Failure to receive the second, manual response during the ~er~.. -:~ response interval, by the terminal 12 following tr~ncmigCi ~r of the intended message, is illdi~ ali~ of the fact that the message for some reason was not properly received and/or 2 0 the response was o~ from îr~n~mic5ion back to the central paging terminal. Again, the ori~ tinS~ caller may be so advised by pre-programmed stored message in terminal 12. In the latter event, the caller may be queried as to whether he or she wishes an imm~ te retry regarding the lGrc.~-r : ~ page message, or 25 wishes to wait for some later time. In any case, the originating caller is advised of the specific status of the paging call. Either it is received and ~ o~l, or it is not.
As lll ~, e~ previously, a Cig~if: -- problem in paging systems with ack-back c~p~hilities is the user IJllC.,.l~il.t~ as to0 whether a further ack-back response, in addition to the first t;~' response, is in order, and, if so, when should such additional manual response be effected.
In the paging system of the present arrangement, the pager wearer is guided through the required procedure both as to 3 5 whelher a manual response is to be made, and if so, when. This is shown more clearly by reference to the flow chart of Figurc 5 `
PCI'/US90/00613 W0 90/10922 ~ 8 -IG~ ,scn~i,.g the pager sidc of the ack-back signal ~-r- ~~S to be effected in the system 10.
As shown, the process or routine begins at step 70 followed by the receipt of a pager address by pager 24 at step 72.
5 Upon processing and rccognition by the pager 24, an automatic ack-back response is generated via the receiver's encoder-controller module 58b at step 74. The controller portion thereof effects the alert and routing of the aYdio to~ the pager speaker 60 at step ?6 and further turns "on" the manual response indicator 10 68. This advises the pager wearer that ? further, manual ack-- back action on his or her part is requircd. If the pager wearer then activ~ates push button 66 so as to initiate a further (manual) ack-back response at step î8, the pager 24 then effects the ;on of a manual response of the affirmative type at step 15 80. This response, as previously l~r~.c.lcc~, may be made at any time during the time the intended mess?ge is being received and ucl~s~d by pager 24 and for sQme set pre-dct~ time thereafter. Upon the pager wearer acliv~li,lg the pushbutton 66 during this interYal, to effect the intended response, the pager 20 turns "off" the manual response indicator, also in step 80, and ends the routine at step 82. ~ .
lIowever, if the pager 24 fails to detect the activation of p ' I _` ~ 66, it waits until the ~çYrir~ti ~r of the response interval at step 84. Thereupon it turns off the manual response 2 5 indicator and transmits a negative manual response at step 86, ~IC~CiU~JUII the routine may be t~ d at step 88.
From the base or central side, the routine begins at step 90, ~.' ciul.ull the particular pager address is tr~ncmil~d at step 92. The channel is then ~,d at step 94 for a given time 30 during ~vhich an ~ ack-back signal may be expected to be received at step 96 for the pager 24 being paged. If the; --ack-back signal is not received by terminal 12 within the time se in stcp 98, the terminal 12 ~: ~s that the pager is not in service and so advises the caller by a pre-programmed message 3 5 stored therein as indicated in step 100, ~' ~ul.oll the routine is ended at step 102.
.
, . . .
woso~to9z2 ~ 3~ ~ ~
If, however, the ~ t-)m~ti~- ack-back response is received at step 96, the intended message may then be ll~ll ,,"ilt~ at step 104. The channel is then monitored for a pre-d~ t~ 1 time at step 106. If the manual ack-back response is not detected within S the time period set in step I10, the terminal 12 d l ~ that "no response is received" (no ~rril..,a,i~G, no negative response) and so advises ~he originating câller, as indicated at step 112, whe,~ oll the routine is ended at step 114. As infli~ i, a program may be set to resend the page if no response is initially 10 received in step 112.
Alternatively, if the second (manual) ack-back response is received by the terminal 12 at step 108, the terrninal further d ~ - s whether such response is a response in the arr.. ali~." see step 80 in Figure 5, or a negative response, as in 15 step 86. If the manual ack-back response is in the arri.-..ali~
sense, terminal 12, by pre-p.og.a.. ,_d slored message, advises the ori~ir~ting caller at step 118 that an ~rri.-.-ali~e message has in fact been received. If the manual ack-back response is in the negative sense, the llri~ir~tinp caller is so advised at step 120 20 accordingly. In either event, the routine is ended at step 122.
There is still one other aspect that needs to be considered for a paging systems of this typc. This is the matter of setting the response interval for rnanually ~s~ ~ing back. As previously described, this interval may c ~ ie..lly begin with the 2 5 l. and reception of the intended message by the called pager and for a ~-I,d~ time II.~ .ear~ . However, in very busy systems, setting this interval routinely may result in less icicr.cy than may .' ~is~ be obtained.
As an alternative to this preset interval, the paging 30 system, or more ac _ 'y, the controller 32 of terminal 12, may effect a specific query of a call pager for a manual ack-back response at a selected but not pre-ordained time. This is reflected in Figure 8 where, after ~...------;ll;..g the intended voice message, following the receipt of the ~ ack-back response in step 10~ of Figure 7, terminal 12 may then return to paging still other pagers in thc system as indicated at step 104a. At an appropriate but variably selected time, terminal 12 may query a particular _ wogo/l0922 ~ ,5~ o PCI/US90/00613 syslem pager for the required manual ack-back response as indicated at step 105. It is to be understood that the manual response interval may be set i~ n~ of the query signal Ll~ by the terminal 12, if so desired. The Fllchh~lltton 66 S may be activated during the set interval, but the pager 24 simply notes such action. The actual rnanual ack-back response is not scnt by the pager until the query signal is received. When such query signal is l~ d it is selected by the terminal 12. This query signal may comprise the pageris address and certain 10 additional information which instructs the pager not to alert but only to activate the manual response indicator 68 on pager 24.
Terminal 12 then monitors the channel for some pre-dct~ cd time, the same as in step 106 of Figure 7, and the routine then COl~tilll ~ in the same manner as previously described.
At the pager side, ihè pager address is received and an gll~omstiC response initiated at steps 72 and 74 as previously described in Figure 5. At step 76, however, the pager alerts and routes the audio to the pager speaker, and the manual indicator is activated at this time. At some time subsequent, as indicated at 0 step 76a, Figure 6, a system query signal is spe~ifi~ slly d and received by pager 24. As in step 78, Figure 5, the pager 24 d~ 5 whether or not the pager wearer has activated the push button 66 or not. If yes, a responsë in the ~rrillllali~., sense is l~ d back at step 80, and if not, a 2 5 response in the ncgative sense is ~ rd back at step 86, ~hc,.i,,po.~ the routine rnay the~ be ended as before at step 88.

WO 90/10922 PCI~/US90~00613 - 5 - 29~6~1 The system 10 may include a paging controller console or terminal 12 which may receive incoming calls at a telephone input port 14 from, first, human callers utilizing conventional or standard ~ phf~ handset 16 or, secondly, from personal S cu~ ,.,t~ or video display terminals depicted at 18, or, thirdly, from page entry terminals as shown at reference 20.
Console terminal 12 will process the paging request, extract the ;Ip~ lial~ address from internal memory and activate the paging tral.c ni~t~r 22 to broadeast the intended 10 paging call, and which in tur~ is received by the a~",lu~.lial~
system pager for processing the information and alerting the paging receiver wearer or user. As will be ~ ' ~luod, the pagers of the system may be of tone only type, as depieted at 24a, a tone and voiee pager, as indicated at 24b or an ~ ie display 15 type, as shown at 24e. As I -~ previously, the system 10 may comprise different types of these .~ ,nced pagers intermixed within the system, or it may be populated by only a partieular type of pagers. But in any event, each of these pagers within system 10 is equipped tû respond with an ~ aek-2 0 baek signal upon being paged (ad.ll~,~scd) by the eentral basestation or l. allslllil~ur 22.
As well known, and as illllctr~ d in Figure 2, a terminal interfaee module 26 aeeepts ineoming ealls from a PABX or a publie s~viteh ~ p~ c network (PSTN) shown in dotted line at 25 28, whieh in turt~ -r~rcs with a standard t~l r'~ lr device 16, a personal COIll~..tl,- or video display terminal 18, and/or a page entry terminal (PET) 20. If the ineoming eall is from a standard tcl~,~h~r- unit, it is plu~,~,sse~ by the module interfaee 26 from an included DTMF deeoder (not shown) c ~ to input port 1 4A.
3 0 If the ineoming eall is from a VDT 18 or PET 20 an internal modem in the module interfaee effeets the proeessing as indieated at inputs 14b and 14d by the referenee "M".
As best seen in Figure 3, the terminal 12, in addition to one or more interfaee modules 26, further ineludes a eontroller 35 32, a synthesizer 34, a memory 36 and an aeknowledge back deeoder 38. With the ~Yreption of the aek-back decoder 38, the other referenced CGlllpO~lC..t parts functioned to ess~n~i~lly route WO go/10922 Pcr/US90/00613 2~45681 - 6 -., .
the incoming paging request at a port 14 on the input side to thc ~Ir ~ .- control ports 30 on the output side. Controller 32 serves as the "brain" of the system and includes ? ni~ ,uce~or ~not srecifirally shown), while the ~ .,.,. 34 generates the 5 sometimes required paging tones cQnctit~tin~ thc pagers address c~ntained within memory 36 along with other system parameters and relevant subscriber informq~ic~ The ack-back decoder 38 receives the various ack-back signals from the systems pagers which are utilized to determine the degree of ~,c fi~' ~ as to 10 whether a particular paging message was received and understood by the pager wearer, as will be described hereinafter.
In any event, terminal 12 along with ll~."i,...ilt~,. 22 and associate antenna 23 ctit-lt~ the base site or system side 13 of the pagirig system 10.
- The pager-side 15 of system 10 c~ ,.;c~s the paging receiver portion 50, the included ack-back encoder 58 and ~Ccociat~d antenna 54. A more detailed ~ ion of a system pager is shown in Figurc 4. In addition to the foregoing, the overall pager unit 24 furthèr includes an antenna switch 56, a 20 ~ JI. portion 52, a speaker 60, a display 62, if of the numeric or all.l.-..~,.... ~;~ type, and a latch 64 and manual button 66 coupled to the ack-back encoder-controller 58b and a manual response indicator 68. Indicator 68 may be an LCD segment or an LED displayed on the outer pager housing. Additionally, it ~nay 2 5 also include an audible 1._ ~ ' normally already a part of the pager unit.
In operation, incoming calls are accepted at the a~ ul~iatè input ports 14 and are sllbs~qllcntly ~-vcei.sed by the controller 32, which, say for example, has a call from a standard 3 o t~l~pho~e for a conventional tone and voicc page, generates the necessary tones for the intended pager as taken from memory 36.
These tones are outputted on the output control lines to lld~ l 22 and broadcast by the antenna 23. The address is received by page antenna 54 and is ~llùcess~d by the pager 35 receiver portion 50. Upon being decoded and l~,co~ d by address decoder 58a, an a~tom~tiC ack-back signal is generated and ~ d back to terminal 12 by pager transmitter portion wo ~10922 ~ sso/006l3 2~56~1 52, which is received and ~.oc~s~d by ack-back` decoder module 38. No action is required by the pager user for this sequence of mm mq~ic~lly reSpnntling and requires only that the pager 24 be turned on and receive the particular address signal.
S Upon receipt and processing of the all~omoti~ ack-back response from pager 24 by terminal 12, the intended message may then be IIA~ d to pager 24 in likc fashion. During the time for processing the message, and for a ~cdut~ ir.ed period thereafter, which concti~t~s a response interval, the pager 10 wearer may activate manual ~_' ~ 66 to generate a further and manual ack-back response. When received and ~.uc~ssed at the base-central site, it is illdicali~, of the condition that the page message was duly received and ulld~ ood by the intended pager wearer. Accordingly, the origin~in~ caller may be so advised by a 15 pre-programmed message stored in terminal 1 2.
Failure to receive the second, manual response during the ~er~.. -:~ response interval, by the terminal 12 following tr~ncmigCi ~r of the intended message, is illdi~ ali~ of the fact that the message for some reason was not properly received and/or 2 0 the response was o~ from îr~n~mic5ion back to the central paging terminal. Again, the ori~ tinS~ caller may be so advised by pre-programmed stored message in terminal 12. In the latter event, the caller may be queried as to whether he or she wishes an imm~ te retry regarding the lGrc.~-r : ~ page message, or 25 wishes to wait for some later time. In any case, the originating caller is advised of the specific status of the paging call. Either it is received and ~ o~l, or it is not.
As lll ~, e~ previously, a Cig~if: -- problem in paging systems with ack-back c~p~hilities is the user IJllC.,.l~il.t~ as to0 whether a further ack-back response, in addition to the first t;~' response, is in order, and, if so, when should such additional manual response be effected.
In the paging system of the present arrangement, the pager wearer is guided through the required procedure both as to 3 5 whelher a manual response is to be made, and if so, when. This is shown more clearly by reference to the flow chart of Figurc 5 `
PCI'/US90/00613 W0 90/10922 ~ 8 -IG~ ,scn~i,.g the pager sidc of the ack-back signal ~-r- ~~S to be effected in the system 10.
As shown, the process or routine begins at step 70 followed by the receipt of a pager address by pager 24 at step 72.
5 Upon processing and rccognition by the pager 24, an automatic ack-back response is generated via the receiver's encoder-controller module 58b at step 74. The controller portion thereof effects the alert and routing of the aYdio to~ the pager speaker 60 at step ?6 and further turns "on" the manual response indicator 10 68. This advises the pager wearer that ? further, manual ack-- back action on his or her part is requircd. If the pager wearer then activ~ates push button 66 so as to initiate a further (manual) ack-back response at step î8, the pager 24 then effects the ;on of a manual response of the affirmative type at step 15 80. This response, as previously l~r~.c.lcc~, may be made at any time during the time the intended mess?ge is being received and ucl~s~d by pager 24 and for sQme set pre-dct~ time thereafter. Upon the pager wearer acliv~li,lg the pushbutton 66 during this interYal, to effect the intended response, the pager 20 turns "off" the manual response indicator, also in step 80, and ends the routine at step 82. ~ .
lIowever, if the pager 24 fails to detect the activation of p ' I _` ~ 66, it waits until the ~çYrir~ti ~r of the response interval at step 84. Thereupon it turns off the manual response 2 5 indicator and transmits a negative manual response at step 86, ~IC~CiU~JUII the routine may be t~ d at step 88.
From the base or central side, the routine begins at step 90, ~.' ciul.ull the particular pager address is tr~ncmil~d at step 92. The channel is then ~,d at step 94 for a given time 30 during ~vhich an ~ ack-back signal may be expected to be received at step 96 for the pager 24 being paged. If the; --ack-back signal is not received by terminal 12 within the time se in stcp 98, the terminal 12 ~: ~s that the pager is not in service and so advises the caller by a pre-programmed message 3 5 stored therein as indicated in step 100, ~' ~ul.oll the routine is ended at step 102.
.
, . . .
woso~to9z2 ~ 3~ ~ ~
If, however, the ~ t-)m~ti~- ack-back response is received at step 96, the intended message may then be ll~ll ,,"ilt~ at step 104. The channel is then monitored for a pre-d~ t~ 1 time at step 106. If the manual ack-back response is not detected within S the time period set in step I10, the terminal 12 d l ~ that "no response is received" (no ~rril..,a,i~G, no negative response) and so advises ~he originating câller, as indicated at step 112, whe,~ oll the routine is ended at step 114. As infli~ i, a program may be set to resend the page if no response is initially 10 received in step 112.
Alternatively, if the second (manual) ack-back response is received by the terminal 12 at step 108, the terrninal further d ~ - s whether such response is a response in the arr.. ali~." see step 80 in Figure 5, or a negative response, as in 15 step 86. If the manual ack-back response is in the arri.-..ali~
sense, terminal 12, by pre-p.og.a.. ,_d slored message, advises the ori~ir~ting caller at step 118 that an ~rri.-.-ali~e message has in fact been received. If the manual ack-back response is in the negative sense, the llri~ir~tinp caller is so advised at step 120 20 accordingly. In either event, the routine is ended at step 122.
There is still one other aspect that needs to be considered for a paging systems of this typc. This is the matter of setting the response interval for rnanually ~s~ ~ing back. As previously described, this interval may c ~ ie..lly begin with the 2 5 l. and reception of the intended message by the called pager and for a ~-I,d~ time II.~ .ear~ . However, in very busy systems, setting this interval routinely may result in less icicr.cy than may .' ~is~ be obtained.
As an alternative to this preset interval, the paging 30 system, or more ac _ 'y, the controller 32 of terminal 12, may effect a specific query of a call pager for a manual ack-back response at a selected but not pre-ordained time. This is reflected in Figure 8 where, after ~...------;ll;..g the intended voice message, following the receipt of the ~ ack-back response in step 10~ of Figure 7, terminal 12 may then return to paging still other pagers in thc system as indicated at step 104a. At an appropriate but variably selected time, terminal 12 may query a particular _ wogo/l0922 ~ ,5~ o PCI/US90/00613 syslem pager for the required manual ack-back response as indicated at step 105. It is to be understood that the manual response interval may be set i~ n~ of the query signal Ll~ by the terminal 12, if so desired. The Fllchh~lltton 66 S may be activated during the set interval, but the pager 24 simply notes such action. The actual rnanual ack-back response is not scnt by the pager until the query signal is received. When such query signal is l~ d it is selected by the terminal 12. This query signal may comprise the pageris address and certain 10 additional information which instructs the pager not to alert but only to activate the manual response indicator 68 on pager 24.
Terminal 12 then monitors the channel for some pre-dct~ cd time, the same as in step 106 of Figure 7, and the routine then COl~tilll ~ in the same manner as previously described.
At the pager side, ihè pager address is received and an gll~omstiC response initiated at steps 72 and 74 as previously described in Figure 5. At step 76, however, the pager alerts and routes the audio to the pager speaker, and the manual indicator is activated at this time. At some time subsequent, as indicated at 0 step 76a, Figure 6, a system query signal is spe~ifi~ slly d and received by pager 24. As in step 78, Figure 5, the pager 24 d~ 5 whether or not the pager wearer has activated the push button 66 or not. If yes, a responsë in the ~rrillllali~., sense is l~ d back at step 80, and if not, a 2 5 response in the ncgative sense is ~ rd back at step 86, ~hc,.i,,po.~ the routine rnay the~ be ended as before at step 88.
