LC7363J, 7363JM SSS Function Specifications . . The LC7363J, 7363JM are capable of pulse dial, DTMF dial and also both types of dialing mixed, as well as redial of these. - 1) Dial Output Specifications . e The output pulse make ratio of OUT-PULSE mode can be set at 33.2 or 40% using the BMR pin. © The output pulse rate of OUT-PULSE mode can be set at 20 or 10pps using the DPR pin. 12 types of DTMF dial signals (1 to 0,>, #) are generated in DTMF mode. « DTMF signals are output continuously when the keys are pressed. ¢ A minimum output for DTMF of approximately 100ms, and also about 100ms for minimum IDP are guaranteed. 2) Summary of Operation « Key input data is written consecutively in the 31 digit buffer memory (also used as RD memory; hereinafter referred to as RD memory). © The dial data in the RD memory is read out according to the set dial rate, and is output at the DP and DTMF pins. ¢ Dial output of more than 31 digits is enabled by rewriting the key data from the top (address 0) of the RD memory, ¢ Because of this, the correct dial does not remain in the RD memory for 32 digits or more, so redial for 32 digits or more is prohibited. Dial data (1 to 0, >, #), mode change data (MC) and pause data (P) are written in the RD memory as 1 digit each. ¢ Dial output mode switching can be performed using the MC key on the key matrix or the P/T input pin. ¢ The dial output can be stopped for 4 seconds with the pause key (P). © One-touch redial can be done using the redial key (RD). 3) Key and P/T Pin Descriptions O Keys 1 to0 These are dial data keys. Data is written in the RD memory. @ x, # Keys In DTMF mode: > and # dial data key InOUT-PULSE mode: > =pause key (P) #=redial key (RD) The >< and # keys for DI[MF mode and x key in the OUT-PULSE mode are for writing data in the RD memory. @ F Key (flash key) - The same operation as for 0.6-second hooking is performed when DP output is turned on for 0.6 second. - Redial can be performed after flash operation. @ RD Key (redial key) 1. Redial operation When the RD key is pressed after hooking (OF F-HOOK pin) or F key operation, the number that immediately precedes will be redialed. Redial is prohibited if the number has 32 digits or more. 2. Pause release The Pause key provides 4-second pause and releases pause attendant on the mode change (MC key, P/T pin). Even if there is a succession of 2 digits or more of pause data in the RD memory, it will all be released. © P Key (pause key) + Stops dial output for 4 seconds. + Data is written in the RD memory.

Key input ] 4 pe Effective key input 4) MC Data Writing in RD Memory « After the MC data is stored once in the MC data flag, it is written in the RD memory when another data key (1 to 0, , #, P) is pressed. « The MC data flag is reset with hooking and the P key. * The MC data flag contents are canceled and are not written in the RD memory when the P/T pin is switched as P>T->P. 5) Notes on Dial Specifications @® Pause operation during mode switching When there is no P data before or after MC data 1. Normal dial Mode change is done and DTMF data key is started during dial pulse output: — After dial pulse ends, pause begins, and the DI'MF signal is output with release using the RD key. DTMF data keyed in after dial pulse output : ~ DTMF signal is output with key-in. 2. Redial for the above After dial pulse ends, pause begins, and the DTMF signal is output with release using the RD key. Continued on next page. No.3199-10/12
