1.0 General Description This service manual provides detailed information regarding the installation, operation, and maintenance of the CES model 4700VP telephone interconnect. The simplex or semi-duplex 4700VP was designed specifically for two way radio applications. The unit is controlled by DTMF (Dual Tone Multi Frequency) audio from mobiles, and contains exclusive interface circuitry and operating software which allows for operation with a wide variety of radio and telephone systems.
2.0 Installation Instructions 2.1 General Information Installation of the model 4700VP should be performed by a qualified two-way radio or communications technician. Ensure that static precautions are observed and that power is not applied during installation. Shielded audio cable should be used for all audio signal line connections to the transmitter-receiver combination. Terminate ground shields at the DB9 connector only to prevent hum and noise due to ground loops.

Squelched/Speaker Audio can be used from the high side of the volume control.
DTMF RX (R51) (1) Send a DTMF tone from the mobile and rotate R51 clockwise until the DTMF LED (DS4) illuminates. Press all the keys on the DTMF mic or encoder and verify that DS4 illuminates every time each key is pressed. Send the connect and disconnect code and verify that the mobile can access the 4700VP reliably. Receive Audio (R50) (1) Call the 4700VP telephone line from another telephone or mobile. (2) Manually answer the line by pressing the connect switch on the front panel.
3.0 Programming Procedures 3.1 Programming the 4700VP The 4700VP can be easily programmed locally with a standard DTMF telephone. (Using a telephone with the DTMF keypad incorporated on the handset can make it difficult to dial and listen at the same time). Programming can also be achieved “over the air” with a DTMF microphone. Remote Program Code must be programmed for over the air programming. 3.
Mobile Activity Timer (32#) If the 4700VP does not detect a carrier, a mobile activity timer starts, and will turn off the transmitter and hang up the telephone line when the preprogrammed timer expires. Warning beeps will be generated 10 seconds prior to disconnect. The timer will reset every time the unit detects carrier from the mobile. The Mobile Activity Timer is programmable in 10 steps. 0=15 sec 1=20 sec 2= 30 sec 3=40 sec 4=50 sec 5=1 min 6=1.
External COR Polarity (41#) The COR input can be programmed for active high or active low polarity. On active high, the input to the 4700VP should be in the low condition (zero volts) with no carrier present and change to a high condition (normally 5vdc) with carrier. This voltage swing must be greater than 2.5V DC. In the active low polarity, the input must be 5V DC with no carrier and 0V DC with carrier, the voltage swing must be greater than 2.5V DC.
Repeat Audio (46#) This allows receive audio to be repeated and transmitted for mobile to mobile communications. This feature is only available in half duplex mode. 0 = off 1 = on Example: To enable the repeat audio function enter the following sequence: 46# 1# Courtesy [roger] Beep (47#) The 4700 provides a short audible courtesy beep to the telephone line each time the mobile user unkeys. This gives an audible indication to the telephone party that they may now begin to talk.
Simplex with VeraTec™ Smart Sampling In the Simplex mode with VeraTec™, (CES proprietary smart sampling protocol), the 4700VP mixes Vox and Sampling modes. When audio is present on the telephone line, the 4700VP will operate in Vox mode until the maximum Vox timer ends. The maximum Vox timer controls how long the 4700VP will stay keyed continuously. The unit will then enter sampling mode allowing the mobile operator to take control of the unit.
Sampling Window Setup (55#) The sampling window duration is the period of time required for the 4700VP to switch the base station radio from transmit to receive to determine whether a mobile is transmitting or not. while observing COR. The sampling window period can be easily adjusted by pressing digits 0 ~ 9 while observing COR. When the proper window timing is set, the COR LED will flash when the 4700VP samples. Pressing the pound key (#) will accept the code and exit the sampling window setup mode.
ANI string (60#) Up to 10 digits ANI can be programmed in the model 4700VP (only characters 0 ~ 9 will be accepted, 3 or more digits recommended). With no ANI programmed, the default connect code is a single star (*) and single pound (#) for disconnect. Example: To program the 4700VP for connect code *123 enter the following sequence: 60# 123# Toll Restrict Override Code (61#) The Toll Restrict Override Code will give privileged users the ability to bypass the toll restriction table.
Toll Restrict (70# ~ 79#) The toll restriction mode of the 4700VP consist of andeny table (codes 70 through 79) and a allow table (codes 80 through 89). Up to 15 digits can be programmed in each of these locations. Wild card (*) may also be used. If no data is entered in the deny table, toll restriction is disabled. This is also true if only wild cards are entered in the allow table. A wild card (*) at the end of the deny string means that an exception may exist, enter these digits in the allow table.
