MODEL NUMBER ALLOCATION Presently, we have a large number of models within each of our various model number series of cordless telephones. Our clients continually request slightly different cosmetic variations of each registered model such as a different case color . In order to control all of these permutations, it is constantly necessary to assign and file, with the FCC, new model numbers to cover these cosmetic variations. Since all models, within a series of cordless telephones, are electrically and functionally identical, varying only in cosmetic detail and to avoid the need to constantly file, with the FCC, to register additional model numbers for cosmetic purposes, we request to register our models as listed tradenames and model numbers: TRADENAMESMODEL NUMBERS BELLSOUTH D(HAC) MH9920(0)(Y)D(HAC) MH9925(0)(Y) AMERITECH D(HAC) MH9921(0)(Y)D(HAC) MH9926(0)(Y) BELL ATLANTIC D(HAC) MH9922(0)(Y)D(HAC) MH9927(0)(Y) PACIFIC BELL D(HAC) MH9923(0)(Y)D(HAC) MH9928(0)(Y) UNISONIC D(HAC) MH9924(0)(Y)D(HAC) MH9929(0)(Y) MH9920 series are 900Mhz Cordless Telephone , Caller ID with Speakerphone NOTE :(0) Zero=Additional charger base suffix "Y" can be added to the model number to represent color variation, can be any letter/s of the alphabet as follows (but not limited to this list) such as : "No suffix"=Gray case B/BK=Black case HG/VHG=Green case W=White case R=Red case RB=Red/Black case PL=Pearl white case such that : MH9920-Model MH9920 is the standard model in gray case MH9920B-Model MH9920 in black case MH9920HG-Model MH9920 in green case FREQUENCE OF 1602 P.L.L * CHANNEL SPACE: 25KHz * 1st I.F.: 10.7 MHz * 2nd I.F.: 450KHz * TCXO(X-TAL): 11.15MHz BASE(MHz)PORTABLE(MHz) CHTXLOCAL(10.7)TXLOCAL(10.7) 1902.125936.825926.125891.425 2902.150936.850926.150891.450 3902.175936.875926.175891.475 4902.200936.900926.200891.500 5902.225936.925926.225891.525 6902.250936.950926.250891.550 7902.275936.975926.275891.575 8902.300937.000926.300891.600 9902.325937.025926.325891.625 10902.350937.050926.350891.650 11902.375937.075926.375891.675 12902.400937.100926.400891.700 13902.425937.125926.425891.725 14902.450937.150926.450891.750 15902.475937.175926.475891.775 16902.500937.200926.500891.800 17902.525937.225926.525891.825 18902.550937.250926.550891.850 19902.575937.275926.575891.875 20902.600937.300926.600891.900 21902.625937.325926.625891.925 22902.650937.350926.650891.950 23902.675937.375926.675891.975 24902.700937.400926.700892.000 25902.725937.425926.725892.025 26902.750937.450926.750892.050 27902.775937.475926.775892.075 28902.800937.500926.800892.100 29902.825937.525926.825892.125 30902.850937.550926.850892.150 31902.875937.575926.875892.175 32902.900937.600926.900892.200 33902.925937.625926.925892.225 34902.950937.650926.950892.250 35902.975937.675926.975892.275 36903.000937.700927.000892.300 37903.025937.725927.025892.325 38903.050937.750927.050892.350 39903.075937.775927.075892.375 40903.100937.800927.100892.400 CIRCUIT DESCRIPTION OF MH9921 V4 1. BASE UNIT : The demodulated signal, resuiting from Double Super Heterodyne system, which appears at output pin no.5 of cn1 is sent to IC6 pin no.15 for Expansion. The expended audio signal is sent to the telephone line via hybrid Transformer HY1. The demodulated data code from CN1 Pin no.7 is Generated by IC1B. Its output is connected to CODE Input Pin no.60 of IC2. The Audio signal receiving from TELE LINE is input to IC6 Pin no.8 for compression. The compressed audio signal from Pin no.3 of IC6 is connected to CN1 Pin no.11 of CN1 modulation. Pin no.62,5 of IC2 is the output port for data codes that should be transmitted to the handset. the data code is connected to Pin no.11 of CN1 for moduiation. CAS signals from tel-line are filtered by AMP IC101B and fed to codec IC102 pin no.4 for decording and them, converted digital sigal transmit to dsp chip ic 102. Camparing the code is correct, DSP (IC103) send CAS detection code to cpu(IC2). After that,ack code from cpu transmit to CO (central office) through tel-line and, CO. Send FSK signal to Base tel-line for final confirmation of Caller ID. FSK is AMP & filterd by IC 105b and fed to codec ic102,next routines for FSK are same as CAS routine.After detection df FSK,CPU generates information commamd (including name,addrecs,telephonenumber,time,date)and transmit the data to Handset through RF section. Stand-by mode : FSK signal detected by IC 105B after ringing is fed to codec(IC102)pin4, and next routimes and poerations are the same as FSK detection at talk-mode. Ext-inuse : In case branch phone is used IC105d7c detect using the branch phone and send the logic- hi signal to CPU. At the moment, Base LED start blinking and Handset LCD displays “EXT-INUSE”. Relay controlling is done by Pin no.27 of IC2. Ring signal monitored by PC1 (PHOTO COUPLER IC) is detected by Pin no.28 of IC2 resulting a data code to the handset. DTMF dialling is generated by IC2 pin 24 this signal output through the base of Q2. When the handset is placed on the base cradle, the charging is detected by Pin no.58 of IC2 sends data codes to handset for security code setting. When the handset is far away from base unit, squelch circuit of IC1C operates and Pin no.8 of IC1C goes "HI". This will be detected by the micro processor and after 20 sec. go to Stand by mode. The power to the base unit is supplied by IC7 (5V REGULATOR IC). The power to the base RF module is supplied by IC9 (5V LOW CURRENT REGULATOR IC). The power to the base CODEC and DSP supplied by IC8 (5V REGULATOR IC). 2. SPEAKER PHONE MODE The audio signal receiving from tel-line is input to IC101B Pin no.6 and fed to CODEC IC102 for converted digital signal transmit to DSP IC103 is connected to IC102 for converted analog signal transmit to AUDIO AMP (IC107). The audio signal receiving form MIC is input to IC101A Pin no.2 and fed to CODEC IC 102 for converted digital signal transmit to DSP IC103 is connected to IC102 for converted analog signal send the tel-line. 1).
