1 Introduction

The model C-1616 is a unique multi-channel, multi-format, and self-contained desktop radio control console. The C-1616 sports a Vacuum Florescent LCD display, which provides channel alpha/numeric indication, clock and

audio-level meter with a modern membrane keypad. These features allows for a more flexible dispatch environment in which the console may be installed. The dispatcher can easily operate the console while sitting or standing.

The C-1616 is a Digital Signal Processor (DSP) based design, allowing easy field programmability using the DTMF keypad on the front of the console. Unlike other manufacturers’ equipment, no additional software is required to program the C-1616 console. Modifications and enhancements can generally be made via a software change only. If the user determines they require a special feature enhancement, please contact the Vega Sales Department for cost and feasibility.

The C-1616’s modular design offers selection and control of up to six base stations, along with selection of sixteen frequencies. The base configuration includes one line card, allowing 2 lines of control. Each line card consists of two independent channels that offer crossmute capability and squelch control features eliminating the unwanted noise that is generally associated when monitoring a selected or unselected line.

The C-1616 will accommodate a desk microphone (or gooseneck microphone) along with a handset (or headset) as indicated on the side of the C-1616 console. When a PTT occurs from either of the two microphones, the other will mute so as not to pick-up unnecessary ambient noise during transmission. When the handset is taken off hook and a line is Selected, the receive audio from that line is transferred to the earpiece.

The console is normally used in conjunction with up to six functionally matching Vega DSP223 or TRA223 Series (or equivalent) tone-remote panels located at each base station. The console is compatible with Motorola, ComNet Ericsson/GE, and other tone-remote control systems employing the industry-standard sequential tone-control format.

The console is connected to the mating panels by means of voice-grade or better leased or private lines (including microwave circuits). Metallic or DC continuity is not required.

2 Hardware Overview

The C-1616 is a multi-line; multi-mode console designed specifically for medium level system requirements. All functions are housed in a single small modern looking console.

2.1 C-1616 Console

The C-1616 consists of the following sub-assemblies enclosed in the single case: Main Processing Board, Line Interface Cards, Keypad/Display Board, and speaker amplifier.

2.1.1 Main PCB

The Main PCB is mounted to the bottom of the enclosure using 5 #6 screws. It contains the DSP that handles all audio processing and user interface features. Three two channel Digital to Analog Converters (DAC’s) are utilized to generate audio for transmission, recordings, auxiliary speaker, main speaker, earpiece, and keyboard feedback. One two channel Analog to Digital Converter (ADC) is resident on the main board which digitizes both the microphone inputs and the auxiliary audio inputs. Each line card contains an ADC as well for the two lines of audio supported on the card. Three 30-pin card slots reside on the main board for each optional line card. A 20-pin header is used to interface the keypad to the Main Board. All audio detection, generation, and filtering are performed within the DSP. Two potentiometers are available for adjusting the handset and desk microphone input levels. A three-pin header is supplied on the main board that connects to the unselect audio control potentiometer.

2.1.2 Keypad PCB

The Keypad board is interfaced to the main board via a 20-pin ribbon cable. The board contains the circuitry to drive the 45 LED’s, decode the keypad matrix, and interface the DSP to the display. The display itself is mounted to the Keypad PCB by a 14-pin header and three screws with spacers.

2.1.3 Line Card

The Line Card is a radio control card using either the standard tone control format compatible with Motorola and M/A-Com/ComNet Ericsson/GE or Local Control relay closure. The line card may be hardware configured for either two or four-wire operation and may be factory modified to accommodate non-industry standard tone control formats if desired. This is usually a software only change. Each card supports two lines and has six potentiometers mounted on the card to support tuning of the Receive, Transmit and Transmit monitor levels.

2.1.4 Internal Speaker Amplifier

The internal speaker has a 5-watt amplifier mounted on the backside of the front cover. Which has one volume control input to which the “Select” volume control is connected. A jumper is used for setting a minimum output level, allowing for audio at some level always being present in the internal speaker.

TRANSMIT

A desk microphone (or gooseneck microphone) may be installed for operation along with a handset (or headset) as indicated on the side of the C-1616. When a PTT occurs from either of the two microphones, the other will mute so as not to pick-up unnecessary ambient noise during transmission. Note that, in dual microphone configurations, the desk microphone is the default microphone. The dedicated PTT button on the handset or headset must be pressed to use the handset/headset.

3.1.1 Common Controls and Indicators

Select Volume Control: Adjusts the summed speaker level of the Selected and Unselect audio’s. A minimum volume level can be set on the speaker card so that the console operator cannot turn the volume to zero.

Unselect Volume Control: Adjusts the speaker level of the Unselected audio. A minimum volume level is preset on the main PCB so that the console operator cannot turn the volume off as long as the master minimum volume is active on the speaker amplifier (JP1). Refer to page 11 for more detailed information.

4 Vega’s C1616

Optional Handset: When you come off hook the handset receive audio is transferred to the earpiece and the microphone mouthpiece becomes active. Unselect audio that is being routed to the external speaker will not be affected.

VU Meter: Displays Selected receive and Microphone audio bus levels. This meter is shown on the top line of the display and utilizes the first 12 display elements from the upper left.

PTT Pushbutton: When pressed all Selected lines will transmit from the default input device (handset, headset, desk microphone, gooseneck)

DTMF Keypad: The DTMF keypad is used for transmitting DTMF digits, selecting frequencies for tone control in tech mode (section 6), and entering alphanumeric strings for line/function tone combinations.

Function Buttons F1-F16: When a function tone button is pressed, a guard tone and function tone burst is sent out. No hold tone is associated with the changing of the function tone. When one of the function tones is selected it will light to indicate which function tone is chosen. A function tone shall remain selected until the operator changes the setting. The console will power up with the last selected line and function tone pair selected. Function tones may also be placed in wildcard groups (section 6.3.3.2), wildcard groups will not effect any function tones in the frequency selection mode.

Line Select Buttons LN1-LN6: Six line select buttons are available. When one of the line buttons is pressed that line enters the Select mode and cancels all other Selected lines (either inactive or Unselected). The ‘1 of N’ mode can be changed by pressing the GRP button ONn, this allows more than one line to be placed in the Select mode. A line or lines can be placed in the Unselect mode by the pressing the UNSEL button on and then pressing the Select line button. You may have any combination of lines placed in the Unselect mode.

Program 1-4: Are used as “soft” programming buttons when in the tech mode. These buttons will have different functions depending on the action required. The bottom line of the display will show their respective functions.

Select Audio LED: The green LED above each LNx Button indicates if the line is selected for transmit audio. Unselect Audio LED: The red LED above each LNx Button indicates if the line is unselected for receive audio

monitoring.

Line Audio Monitor LED: The yellow LED above each LNx Button indicates receive audio activity on a line. Transmit LED: This LED lights when any PTT source is depressed keying up the console. It will also blink if a

2175 Hz hold tone is detected on the selected TX audio lines. This would indicate to the operator that another console is currently transmitting on one of the selected channels.

Unselect button: Pressing the line buttons while the UNSEL button is on will place the respective lines in Unselect mode. Pressing a line that is already in the Unselect mode will deselect the line. Pressing a line that is already in the Select mode will have no affect.

Group button: The 1of N reset function of the C-1616 will be suspended while the GRP button is on. This allows the operator to place more than one line in Select mode. The C-1616 allows four preprogrammed groups. These preprogrammed groups will be applied to the console if the ‘A’, ‘B’, ‘C’, or ‘D’ in the DTMF keypad is pressed while the GRP button is held down. A programming selection allows the technician to apply a preprogrammed function tone or the last used function tone to the group.

TX all button: The TX button allows the operator to place all lines in the Select mode. A programming selection allows the technician to apply a preprogrammed function tone or the last used function tone to the group.

RX all button: The RX button places all cards not in the Select mode in the Unselect mode. Supervisory button: The SUP button allows one console operator to disable any other console which is connected

to the supervised line. Monitor: When the Monitor button is pressed a Monitor tone burst is sent out. The Monitor tone burst consists of a

guard tone and function tone of 2050Hz. An LED indication lights for the duration of the tone burst. Intercom (IC): When the Intercom button is pressed and held down the C-1616 shall transmit audio without

activating the tone generator. Intercom is considered a PTT operation with the tone generator disabled.

3.2.1 Rear Panel Ports

Line Ports 1-6: The C-1616 can accommodate up to six-lines, in multiples of two. The six-line connectors are

available on the rear of the unit. The connectors are standard eight pin RJ-45 connectors. The pin out of the connector appears in Figure 3. The numbering of the pins are shown in Figure 2 for reference.

Auxiliary Audio Input: The external 3 pin terminal block provides Audio Input, PTT, and GND line. Pulling PTT to ground activates the Audio Input line for transmitting. This input is a high impedance capacitance coupled input.

Auxiliary Speaker: Is a capacitance-coupled output capable of driving a 600-ohm load at 0dbm. Footswitch: This input acts as a console PTT when it is shorted to ground Battery backup: The Auxiliary power input is a diode-protected +12V input used for battery backup. Pin (E) is

also connected to the chassis allowing for positive grounding of the unit.

Serial port: Allows for communications between consoles. Normally used when cloning other consoles. Auxiliary Relay Output: Depending on the setting of the AUX button in the tech mode, this output is a relay

closure that can be used for whatever purpose is required. Record Output: Has both unselected and selected notched audio 600-Ohm transformer output for connection to a

voice-logging recorder.

4 Functional Description

4.1 Grouping Options

4.1.1 Basic Line/Function Tone Operation

The basic operating scenario would be a single line and function tone selected. Lines can be selected individually by pressing any LN1-LN6 and function tone button F1-F16. Upon keying the microphone, a high level guard tone followed the selected function tone is sent out, the low level guard tone is then transmitted along with the microphone audio. Each Line/Function pair is unique and can have its’ own alphanumeric characters assigned to it in the programming mode. The default characters have the LnX FY label in the display with X the line number and Y the function number. Function Buttons can have either single or dual functions and is setup in the tech mode.

4.1.2 GRP and TX ALL Buttons

The GRP button is a press ON/OFF button that disables the 1of N functionality of the console. When the GRPSEL button is selected it will illuminated and the operator can set up a Simul-group with as many tone lines desired. As long as the button is illuminated the operator may add or delete lines in the group. The Green LED above each line selection button denotes that the line is selected for transmission and reception. When the operator is finished setting up the Simul-group the operator presses the GRP button again to revert back to the 1of N mode.

The group button is also used to select up to four preprogrammed groups. Within the tech mode, it is possible to set up preprogrammed groups. By assigning certain groupings of lines to the Groups ‘A’-‘D’ a simple two button sequence can be setup to select multiple lines.

Note: Lines that are setup as Local Control cannot be mixed with tone control lines in the same group select mode. Likewise you cannot TX ALL if you have Local control and tone control lines mixed. You will receive an ERROR MESSAGE. They must all be of the same type of control lines tone or local control.

TX ALL (Transmit All): This feature gives the user a convenient means of Selecting all lines for Simultransmissions without having to group select one at a time.

To initiate Simulcast, momentarily touch the "TX ALL" on the keyboard. The line description will change to "Group", and all available lines will automatically be Selected.

To disengage Simulcast, simply Select a single line in the usual manner, or press TX again to revert to the previous setup.

Note: You cannot TX ALL if you have Local control and tone control lines mixed. You will receive an ERROR MESSAGE. They must all be of the same type of control lines tone or local control.

4.1.3 UNSEL and RX ALL Buttons

The UNSEL Button functions the same way as the GRP button. The UNSEL button is a press ON/OFF button. When the GRPSEL button is illuminated the operator is able to set up any combination of lines as desired for monitoring only. As long as the button is illuminated the operator may add or delete lines to the group. The red LED above each line selection button denotes that the line is Unselected for reception. When the operator is finished setting up the group the operator presses the UNSEL button again to turn off the mode.

RX ALL (Receive All): When pressed all lines are put into the unselect receive mode. Any line that is in the Select

mode will automatically become part of the Unselect group when it is taken out of Select mode.

4.2 Other Control Buttons

4.2.1 Supervisor Button

The SUP Button is used to disable all units on a particular line. Its connection is similar to that of the crossmute function. Tech mode is utilized to determine which consoles will have supervisory capability. It is possible to setup only specific consoles with this feature. If a console has the feature enabled, by pressing the SUP Button, the Button will light and disable all connected paralleled consoles. On the consoles that are being supervised, the SUP Button will blink, if they have selected a line that the supervisor has selected. Figure 3 shows the connection scheme required to utilize this function. Pin 2 of all consoles are connected together. In addition, Pin 8 is also connected together on all consoles, serving as a common ground for all consoles. Assuming that console 1 has supervisory capability, when activated, Line 1 on parallel consoles 2 and 3 would then be inhibited.

4.2.2 MUTE Button

The MUTE Button is used to mute unselect audio. It is programmable in tech mode to be a mute when pressed, or mute for a programmable period of time. As long as MUTE is active, the Button will be lit up.

4.2.3 AUX Button

The AUX Button has up to four functions, selectable in tech mode:

1) DTMF store and transmit DTMF

2) Second Alert tone ALERT

3) Toggle relay control TOGGLE RELAY

4) Momentary relay control MOM RELAY Option 1, DTMF store and transmit, allows a programmed string of DTMF characters to be entered and transmitted.

In addition, the function will remember the last string sent and can be recalled by pressing a Program Button. Option 2, ALERT, allows the AUX Button to serve as the Alert 2 Button. In this mode it sends out the programmed

Alert 2 tone. Option 3, Toggle Relay, give the AUX button the ability to control the AUX RELAY output on the back panel.

When pressed, the Button will light and the relay will close. The next time the AUX button is pressed, the Button’s light will turn off and the relay will open. The relay is rated to handle 500mA at 12VDC or 250mA at 115VAC.

Option 4, Momentary Relay, closes the relay for as long as the AUX button is pressed. The relay is rated to handle 500mA at 12VDC or 250mA at 115VAC.

4.2.4 Alert Button

The Alert Button is used to send the programmed Alert sequence. Tech mode is used to set up the cadence assigned to this Button.

4.2.5 Intercom (IC) Button

When the IC button is pressed and held down the C-1616 transmits audio without activating the tone generator. Intercom is a PTT operation with the tone generator disabled. This is useful for communications between paralleled consoles.

5.3 FEATURE DESCRIPTION

5.3.1 Crossmute

When a parallel console operator keys a microphone in the same room, the crossmute function will mute the receive audio path of other parallel consoles. This prevents any unwanted audio loops which would occur causing a loud squeal on the paralleled speakers.

Figure 6 Crossmute Diagram

Feedback may be avoided by muting the receive audio of the line card which is in parallel with a transmitting line card. This may be accomplished by connecting pins 1 and 8 of each of the consoles to be crossmuted as shown in Figure 7. Pin 8 must be connected to provide a common ground. Figure 5 illustrates the connections between consoles 1 through 3 that are in the same room and when one transmits, the receive audio on line 1 will be muted. Console 4 is off-site with no possibility of feedback, therefore, it is not being muted.

Note: The intercom function will not work between crossmuted consoles.

Offsite Console 4:

Line 1 Line 1 Line 1

5.3.2 Relay Contact Closure For Local Control

The relay is normally open and provides a dry contact closure during PTT functions between pins 7 and 8 of the line jack. The relay closure can carry 500mA at 12VDC or 250mA at 115VAC. When using the intercom function the relay is not activated.. If this relay closure is used for local control (or any other case where tone bursts are not used for signaling) disabling the tone generation is recommended by entering the tech mode.

5.3.3 Two-Wire/Four-Wire Mode

Each Line Card comes standard with a jumper selectable two or four-wire option. Note: The Line Cards are shipped in the four-wire mode. Two-wire mode is accomplished by the following jumper positions:

Line 1, 3, 5: Line 2, 4, 6:

Two-Wire: Jumper Position Jumper Position

JP12 A JP10 A JP13 A JP11 A Four-Wire: Jumper Position Jumper Position JP12 B JP10 B JP13 B JP11 B The RX pair is now on pins 3 and 6 on the connector and the TX pair is on pins 4 and 5. Once transmit and receive

paths are separated the impedance of each side must be set.

10 Vega’s C1616

5.3.3.1 RX Side Settings

For 4-wire lines the RX side is jumper selectable for either 600 or 10k ohm impedance. If only one Line Card is on the line (no parallel consoles) then place J9 (Line 1,3,5) or J8 (Line 2,4,6) in the A position for a 600-ohm line impedance. If more than one Line Card is on one line then place J9 (Line 1,3,5) or J8 (Line 2,4,6) on ONE console in the A position and all other consoles in the B position. Each console added to the system will result in line loss. The following chart gives an indication as to how much loss can be expected. The first console in the system is set for an impedance of 600 ohms out (approximately). Each console added to the system thereafter is set for an impedance of 10k ohms. As the chart indicates on the following page, the more consoles bridged on the line, the lower the line impedance and the greater the loss in audio level.

Console added Position Impedance Impedance Loss (dB) 1 A 604 604 0.0 2 B 10k 569 -0.5 3 B 10k 539 -1.0 4 B 10k 511 -1.5 5 B 10k 486 -1.9 6 B 10k 464 -2.3

For 2-wire lines always place J9 and J8 in the “B” position.

Level adjustment can be made to the receive audio by adjusting the Line RX IN, see section (5.4.1.3).

5.3.3.2 TX Side Settings

Two jumpers on the transmit pair allow a degree of control over the output impedance. The following chart lists the jumper positions for each card depending on how many consoles are placed in parallel. All cards should have the same jumper settings.

Consoles in parallel Individual TLM Output Impedance (per console)

Line 1,3, 5: J4 J5 Line 2, 4, 6: J6 J7

1 (one console on line) A A A A 600 ohms 2 B A B A 1200 ohms 3 A B A B 1800 ohms 4 B B B B 2400 ohms

The TX levels can be set by potentiometer on a per line basis. Refer to section 5.4 level adjustments for setup procedures.

5.3.3.3 Transmit Monitor

In a four-wire system the transmit line may be monitored by the receive circuits by changing a setting in tech mode. Refer to section 5.4.1.2. for the monitor level setup adjustment. The transmit monitor is not needed in two-wire mode as the transmit audio is already on the receive circuit.

5.4 Level Adjustments

Figure 4 in this section, shows a top view of the Line Card with the adjustment points labeled. The potentiometers are available without taking the card out of the chassis.

5.4.1 Transmit Side Adjustments

The transmit audio consists of multiple audio sources – microphone audio, AUX input, function tones, and DTMF tones. Each audio sources is summed or generated in the DSP with the analog signal being generated on a single DAC. The following is a list of the potentiometers that affect the transmit path.

Remote Control Console 11

5.4.1.1 Transmit Level Setup

The transmit level potentiometers are used to adjust the output levels of the transmit audio so that it is calibrated with the onscreen level sets found in the tech mode. Calibration of the Transmit lines will vary depending on system variables as well as the number of consoles found in parallel on the line. The tech mode can be used to generate a test tone at a given amplitude. R41 and R42 should then be adjusted with a level meter used to set the actual output level to match the generated value.

5.4.1.2 Transmit Monitor Setup

The transmit monitor provides a portion of the transmit audio of a four-wire circuit to the receive path. This allows the console operator to listen to the transmissions of parallel console operators. To set this level have a parallel console operator select a line and press the intercom button. Adjust R40 and R39 on each four-wire circuit until the level is comfortable in the handset/headset earpiece or the speaker.

5.4.1.3 Receive Level Setup

The receive side level potentiometers are used to adjust the input levels into a range that is acceptable to the C-1616. Typically, a +10dBm test tone is injected in to the C-1616 as receive audio. The audio level is then measured at TP2 for Line 1 and TP1 for Line 2 with respect to ground. The measurement should be about 3.4 Vpp or 1.2Vrms. However, if receive audio levels are not in the +10dBm range, these pots can be used to bring the audio level up to the desired receive levels. 3.4Vpp is about the maximum value for the loudest receive audio. Above 3.4Vpp will saturate the ADC input stage and distortion will occur.

5.5. Microphone Level Adjustment

Adjusting handset/headset microphone levels. Make a vocal tone into the handset while adjusting R72 on the Main PCB for 3.5Vp-p at TP2. The sidetone cannot be adjusted, speak into the handset and listen to the earpiece. You should hear a portion of your voice being routed back to the earpiece.

Adjusting desk microphone/gooseneck microphone levels. Make a vocal tone into the desk microphone/gooseneck microphone at the distance you expect the operator to be positioned and adjust R71 on the Main PCB for 3.5Vp-p at TP7.

5.6. Minimum Speaker Level Adjustment

A minimum volume level can be set by moving JP1 to “B” position on the speaker Amplifier PCB, preventing the operator completely turning off the volume of the speaker.

12 Vega’s C1616

6 Tech Mode

The tech mode allows a technician to program the internal settings of the C-1616 console.

The tech mode is entered by pressing MUTE - F6 - *(star) simultaneously. The technician may be required to

enter a PIN number to allow entry. See the section 6.3.4.1 on setting up the PIN number. The Opening Menu is displayed when tech mode is entered. In addition to the information on the display you will visual see the MOM, LN1-LN6, ALERT, AUX, F1-F16, GRP and the MUTE buttons also flash indicating you are in the tech mode of operation. These buttons also provide setup options when pressed, refer to section 6.0.4. for further information.

6.0.1 Erasing all settings

All of the settings in the console can be reset to factory defaults by pressing and holding both “IC” and “*” and then applying power. The screen displayed asks if the user wants to restore defaults or not.

PROG1 - Answer, YES and you will clear all settings to the factory defaults. PROG3 - Answer, NO and you will enter the user mode.

6.0.2 Resetting the PIN Number

In the event the PIN number is either forgotten or not known, the test jumper J17 on the main board inside the unit can be used to enter a self test mode and reset the PIN. With the power removed from the unit, move J17 to the “B” position on the board. Power up the board. The PIN number is cleared allowing immediate entry into the tech mode. Power down the board and move the J17 back to the “A” position. Close the case and resume normal operations with the C-1616.

6.3.3.1.1.4 Enable/Disable PTT tones with DTMF

This setting governs whether PTT functions are generated when the DTMF keypad is used without the IC or PTT key. If this option is set to “Send PTT Tones” the unit will check the line(s) that are selected and see if they are set to be tone or local relay control. When the DTMF digit is pressed, depending on the selected lines configuration a PTT tone burst or local relay closure will occur before the DTMF digit starts transmission. If this option is set to “No PTT Tones”, no PTT function will be sent and the DTMF audio will be placed onto the selected lines.

6.3.3.1.1.5 Incoming Select Call DTMF String Setup

The C-1616 has the capability of recognizing a DTMF string of up to 10 digits in length incoming on any line, monitored or not. When this programmable string is decoded, the unit will Unselect the line for a programmable period of time to allow the remote user the opportunity to make a short transmission which the console operator can monitor. After the programmable period of unselect time has expired, the Unselect LED (Red led) for the line on which the DTMF string was decoded begins to flash and continues to flash until a PTT operation is completed on that line. This blinking light serves as a reminder to the console operator that a call came in and needs to be responded to. Editing the incoming DTMF sequence is completed from the screen pictured above. The digits are entered with the DTMF keypad and the programmable keys.

6.5 Line Tone/Local Screen

The Line setup menus allows for the parameters unique to each line to be setup on a per line basis. Parameters that can be adjusted by pressing the LN1-LN6 keys from the top level menu include: Enable/Disabling of the line, Tone or Local control, Cross Mute, Squelch, TX Monitor, AGC, TX Enabled, and Unselect Audio Forced. The LN1-LN6 keys are active at all times in the menu; for example, to disable AGC on all lines, AGC could be selected on LN1, setup, then LN2-LN6 could immediately be pressed from within the AGC menu, eliminating going back and then back through the menus for each line.

6.5.1 Enable/Disable the Line

Disabling a line sets the line so that a user cannot either select or unselect its audio. No LED indicators will show if the line is disabled. In addition, it would generally be desired to set a line to be disabled if no card is present for that line. If no card is installed, and the line is selected, an error message will be shown saying that the line is not available and requiring the user to press the PROG1 button to continue. If the line is disabled from this menu, then the console just ignores the key.

6.5.2 Tone or Local Control

This screen allows the technician to determine if a line is tone control or local control. If a line is tone control then a tone burst is transmitted before voice is allowed to drive the line and a hold tone is sent out with the voice to provide a positive key for the remote adapter. If a line is a local control line then the tone generator is not activated and voice drives the line when the PTT button is pressed. The line number of the selected line appears in the top line of the display. The example shows that line 3 has been selected. The text at the right side of the top line shows which mode the line is programmed with.

30 Vega’s C1616

7 Sample Setup Procedure

The following example sets up the audio levels on both transmit and receive sides.

7.1 Transmit Path:

The transmit path begins at the microphone of your choice and ends with the transmit line card jack.

7.1.1 Microphone adjustments

There are two microphone inputs to the C-1616. Both inputs are accessible from the side of the unit. One is a fourwire connector and the other is a six-wire connector. The four-wire connector will accept either a handset or headset. The six-wire connector will accept either a desk microphone or a gooseneck microphone. Both connectors may be used at the same time. The six-wire connector has priority. Transmit audio from the six-wire connector is blocked only when the PTT of the four-wire connector is active.

Both the handset/headset and the desk/gooseneck microphone inputs go through dedicated preamplifier stages and are then brought into a CMOS switch that selects the port to be connected to the ADC of the DSP by the PTT source. In setting the microphone levels the goal is to adjust the preamps so that nominal voice levels through both microphones (if two are being used simultaneously) are of equal level at the input of the ADC. The following procedures will guide you through the tuning process:

7.1.2 Adjusting handset/headset microphone levels

Make a vocal tone into the handset while adjusting R72 on the Main PCB for 3.5Vp-p at TP2. Speak into the handset and listen to the earpiece. You should hear a portion of your voice being routed back to the earpiece.

7.1.3 Adjusting desk microphone/gooseneck microphone levels

Make a vocal tone into the desk microphone/gooseneck microphone at the distance you expect the operator to be positioned and adjust R71 on the Main PCB for 3.5Vp-p at TP7.

7.2 Alert tone adjustments

The Alert tone button on the keypad produces a 1000Hz tone on the transmit audio. If no cards are in the transmit condition the console will key up the Selected cards and transmit the Alert tone. If the Selected cards are already in the transmit mode when the Alert button is pressed then the C-1616 will just add 1khz to the transmit audio path.

7.2.1 Alert tone frequency

The alert tone frequency is adjusted in the tech mode. See section 6 for more information. The alert tone can be adjusted in 1Hz increments to any desired value.

7.2.2 Alert tone level

The alert tone level is set in the tech mode. See section 6 for more information. The alert tone level can be adjusted in 1dBm increments.

7.3 Line Card Transmit Path Adjustment

Once the microphone audio has been digitized, the DSP will first route it through a 2175Hz notch filter to remove 2175Hz components from the voice. This is done to make sure that no component of the microphone audio will interfere with the 2175Hz hold tone. At the output of the notch filter the microphone audio is summed together with the last of the signaling components. From this point the total transmit audio mix is sent to the DAC and then to the individual output drivers of the Line Cards.

7.3.1 Transmit Level Adjustment

The transmit level setup potentiometers are used to adjust the levels of the transmit audio so that it’s calibrated with the onscreen level sets found in the tech mode. Calibration of the TX lines will vary depending on system variables as well as the number of consoles found in parallel on the line. The tech mode should be used to generate a test tone of given amplitude. R55 and /or R56 should then be adjusted with a level meter used to set the actual output level to match the generated value.

Remote Control Console 31

7.3.2 Transmit Monitor

The four-wire transmit monitor provides a portion of the transmit audio to the receive path. This allows the console operator to listen to the transmissions of parallel consoles. To set this level have a parallel console operator intercom on the line to be set. Adjust R57 and/or R58 until the level is comfortable in the handset/headset earpiece or the speaker.

7.4 Receive Path

The Receive path begins at the input to the line card and ends with a speaker or earpiece. There are very few adjustment that need to be made to the receive path. The DSP will detect and compensate for most variations in audio levels.

7.4.1 Four-Wire or Two-Wire?

If the circuit is a four-wire circuit then J12 and J13 (Line 1,3,5) and/or J10 and J11 (Line 2,4,6) are in the B position. The RX impedance for the four-wire mode is generally 600 ohms. If this card is the only card on the line or if it is a terminating card for a group of cards hooked in parallel then the impedance of the RX side should be 600 ohms. This is accomplished by changing J9 (Line 1,3,5) or J8 (Line 2,4,6) to the A position. If a high impedance (10k) is required then place J9 (Line 1,3,5) or J8 (Line 2,4,6) in the B position.

If the circuit is a two-wire circuit then J12 and J13 (Line 1,3,5) and/or J10 and J11 are in the A position. The 600 ohm line impedance is provided by the TX side so RX impedance should be high. Move J9 (Line 1,3,5) and/or J8 (Line 2,4,6) to the B position for a 10k ohm RX impedance.

7.4.2 Receive Level Setup

The receive side level potentiometers are used to adjust the input levels into a range that is acceptable to the C-1616. Typically, a +10dBm test tone is injected in to the C-1616 as receive audio. The audio level is then measured at TP2 for Line 1 and TP1 for Line 2 with respect to ground. The measurement should be about 3.4 Vpp or 1.2Vrms. However, if receive audio levels are not in the +10dBm range, these pots can be used to bring the audio level up to the desired receive levels. 3.4Vpp is about the maximum value for the loudest receive audio. Above 3.4Vpp will saturate the ADC input stage and distortion will occur.

7.4.3 Line Activity Monitor (LAM) / Squelch Control

The yellow LED in the above each Line button (LN1-LN6) is the LAM. It will blink when activity is on the line. The default level for the C-1616 console to trigger the LAM is -10 dBm. The trigger point can be changed within the tech mode. Note that the LAM can be used as a squelch circuit. The Select and Unselect audio paths may be independently controlled by the LAM. Both options can be configured in tech mode.

7.4.4 Recorder Output

A 600 ohm balanced notched audio output provides a summing of the transmit and receive audio’s for the use of an external recorder. The actual audio sent to this output is the select and unselected audio. The output level can be controlled from within the tech mode.

7.4.5 Auxiliary Speaker Output

The auxiliary speaker output can be used to drive the unselect audio to an external amplified speaker, thereby eliminating it from the built in speaker. This can be useful if the console operator needs to be able to differentiate between the two audio sources. This outputs amplitude can be controlled from within the tech mode.

7.4.6 Earth Ground

While Telex-Vega recommends that the unit be tied to earth ground though the AUX power connector on the back of the unit, JP21 exist in the unit to allow the chassis ground to be tied to the signal ground of the unit. It is imperative that chassis ground to tied to some fixed reference for proper operation of the unit. The line filtering is dependent on a solid ground to function correctly.

32 Vega’s C1616

8 Theory of Operation

The C-1616 is a Digital Signal Processor (DSP) based product. Because of this, many of the signals that once could be probed on older products, are handled within the DSP itself. This would include DTMF generators and decoders, notch filters, tone generators and decoders, and all of the audio summing. A great deal of the gain controls are also included within the software of the DSP. Because of this, hardware is simplified at the expense of software creation time and user serviceability. The next sections discuss the portions of the C-1616 that can be tested using a common oscilloscope and voltage meter by a qualified service technician.

8.1 Audio Input Paths

Audio can be input from three locations, not counting the line interfaces, including the desk microphone jack (J6, RJ11 modular), handset jack (J5, RJ-12 modular) and the auxiliary connector on the rear of the unit. For each of these inputs, a single inverting Op-Amp gain stage exists to bring the level of the audio up to approximately 3.8Vp-p. This is the optimum level for the analog to digital converters (ADC). The desk microphone and handset share one half of the ADC (U23) with a CMOS switch (U22) being used to connect audio from the appropriate source to the actual input pin of the ADC. The trim potentiometers R71 and R72 set the audio levels from the handset and desk microphone jacks.

The auxiliary input (J4) is used to include an additional audio source into the transmit path. It has an integrated PTT input that when pulled low will select audio from this source for transmission. This input also utilizes a single inverting Op-Amp stage to set the input gain. The factory default setting is a gain of 1. If an external source or audio is to be used, its output level should be on the order of 3.5 Vp-p.

8.2 Audio Output Paths

All output audio is generated in the DSP and sent to the various Digital to Analog Converters (DACs) for export from the C-1616. The three DACs are U13, U14, and U15. Each of these is a dual channel DAC allowing for 6 different audio sources. Each is used for different purposes.

Starting with U13, the left output is used for the handset sidetone. It is sent through a unity gain Op-Amp stage and fed directly to the Desk microphone interface. Since the handset level can be controlled within the software of the C1616 techmode, no gain set control is required for this circuit. The right channel of U13 is not used at this time.

U14’s left channel is the TX audio source. This is the source of all the audio that gets transmitted. This includes control tones, DTMF, and voice. All audio for this output is generated in the DSP and generated in the analog domain from this DAC. The signal is fed through a single unity gain Op-Amp stage and then distributed to each of the line cards where it is further amplified and coupled out of the unit. The right channel of U14 is the Select Audio source. It utilizes a unity gain Op-Amp stage for buffering and then is sent to the speaker amp.

U15 is used for the unselect audio source and the tape jack output. The unselect audio is the left channel. It has a single Op-Amp stage in it. In addition, a connection is made to the unselect audio level knob on the front panel. From the output of the Op-Amp, a CMOS switch (U22) is used to determine the routing of the audio. A low input on Pin 10 of U22 causes audio to be routed to J3, the external speaker jack. A high input routes the audio to the internal speaker where it is summed with the select audio. The right channel of U15 is the tape jack output. A single OpAmp is used to buffer the output of the DAC to a transformer which is used to set the 600 Ohm output.

8.3 Line Card Paths

The line card has two primary functions. First, the transmit audio is generated on the left channel of U14. From there is sent in parallel to all three card slots. Once the audio is on the card, it is fed to CMOS switches U2 and U3, which are used for mute control for each line. A gain set Op-Amp (U7 and U8) is used next with a trim pot (R55 and R56) to set the levels to compensate for line impedance’s. Finally, the audio is sent through a pair of unity gain OpAmps set to generate differential audio in the TX transformers (T3 and T4). The output of the transformers are then passed through a sequence of parts designed to protect the unit for RFI and other externally generated noise.

The receive path enters through RFI protection circuits into transformers T1 and T2. A single gain stage is used to set the levels of the incoming audio. The outputs of these are sent to the ADC (U9) that is resident on the card. For this reason, the receive audio only exists for a short run on the line cards themselves before being converted to the digital format. Individual receive audio will not be found on the main board in analog form.

Remote Control Console 33

The receive path also has a tie in to the transmit path. One of the taps on the TX transformers (T3 and T4) is fed to an Op-Amp stage that is then summed into the receive path Op-Amp. Gain set Potentiometers (R57 and R58) can be adjusted to change the relative TX Monitor levels.

8.4 Keypad/Display Board

The Keypad board is a purely digital board with no user-serviceable parts. It consists of a 7 x 8 keyboard matrix, 39 LED drivers, and a driver for the 20x2 vacuum florescent display. TX and RX audio are not present on this board.

9 Line Card Installation

Installing and removing line cards can be completed in the field by qualified personnel. The steps for this process are listed below.

1) Remove power from the console.

2) Remove the four flathead screws holding the top of the case one. Two on each side. A phillips screw driver will

be required.

3) The case top should be removed in a vertical direction until the finger on the left side of the case clears the tops

of the handset and desk microphone jacks. At this point, move the case somewhat forward as the cable for the speaker amp will be right under the lip of the rear of the case. Once the case top is clear of the bottom, set the top on its sides to the left of the case. Sufficient cable length is available for this without disconnection of cables.

4) Remove the hole cover for the line card position you wish to install. The screw for this is located on the back

panel.

5) Insert the card into the slot making sure that that two RJ-45 jacks are flush with the back of the C-1616.

6) Place the card hold down bracket in position and tighten the screw from the back side of the case. This locks the

card into position.

7) Place the top back on by first making sure that the speaker amp RJ-45 cable is under the lip of the rear of the

case.

8) Replace the four screws removed in the first step. An exploded view of the case can be found with the schematics and parts placement drawings.
