C. DIP Switch Programming
1. Auto Answer Feature ON/OFF (DIP Switch 1)
DIP switch 1 is for turning the Auto Answer feature ON and OFF. The E-10A/E-20B is
factory set to auto answer when an inbound call is detected.
2. Dial Tone Detection ON/OFF (DIP Switch 2)
With DIP switch 2 in the ON position, if the E-10A/E-20B detects more than 5 sec-
onds of continued dial tone, the unit will automatically disconnect. If the E-10A/E-20B
is installed on a continuously noisy line, it may detect the noise as dial tone and auto-
matically disconnect. If this happens, turn the dial tone detection (DIP switch 2) OFF.
3. Programming Mode ON/OFF (DIP Switch 3)
With DIP switch 3 in the OFF position, the E-10A/E-20B is in the "Normal Operation Mode" (factory setting). By placing DIP switch 3 in the ON
position, the E-10A/E-20B's programming mode is enabled. The programming mode is used for adjusting the Call Length Time Out, Silence Time
for automatic disconnect and the Talk/Listen delay (VOX switching speed). These features are set from the factory and normally do not need
adjustment. If adjustment is necessary, see Programming sections D - I.
D. Accessing the Programming Mode
The E-10A/E-20B can be programmed from any Touch Tone phone using a telephone line, Viking model C-200 or C-2000A Entry
Phone Controller, analog PABX/KSU station or a Viking model DLE-200B Line Simulator.
Step 1. Move DIP switch 1 to the ON position (sets unit to answer incoming calls - see section C).
Step 2. Move DIP switch 3 to ON (incoming calls automatically enter the programming mode - see section C).
Step 3. From a Touch Tone phone call the line attached to the E-10A/E-20B.
Step 4. When the E-10A/E-20B answers, 2 beeps will be heard and you will automatically enter the programming mode.
Step 5. When finished programming, enter "0000" to exit programming and move DIP switch 3 back to OFF (see section C).
E. Quick Programming Features
Call length time out (1-9 minutes), blank = disabled (factory set to 11111 = 5 minutes) ..................................
Silence time out for disconnect (10-90 seconds), blank = disabled (factory set to 1111 = 40 secs) ................
Talk/listen delay (VOX switching speed) 0.1 - 0.9 seconds (factory set to 111 = 0.3 secs) .............................
Forced hang-up command (used to exit programming and hang up) .............................................................
F. Programming Beeps
If a valid "Feature" is entered, a single beep will be heard. If an invalid "Feature" (five or more zeros) is entered, 3 beeps will be
heard and the E-10A/E-20B will hang up. If a valid "Time" is entered 2 beeps will be heard. If an invalid "Time" is entered, 3 beeps
will be heard and you will have 20 seconds to enter the next valid "Feature".
G. Call Length Time Out
This feature selects the maximum length of time that calls can be connected.
Programmable in increments of 1 minute up to a maximum of 9 minutes.
Programming nothing in the time value location will disable the call length time
out. With the call length disabled, the E-10A/E-20B phone must rely on CPC,
busy, silence or return dial tone to hang-up. Use the chart at the right. * Note:
The factory default is 5 minutes.
H. Silence Time Out
This feature selects the length of time that calls will remain connected without
voice activity. Programmable in increments of 10 seconds up to a maximum of
90 seconds. To disable the silence time out, program nothing in the time value
location. Use the chart at the right. * Note: The factory default is 40 seconds.
I. Talk/Listen Delay (VOX Switching Speed)
This feature selects switching time between talk and listen modes (VOX switching time). Use the chart above.
* Note: The factory default is .3 seconds.

When the push button is pressed, the E-10A/E-20B phone goes off-hook, much like a standard speaker phone. In the event that the line is busy, the E-
10A/E-20B will hang up. The E-10A/E-20B will also automatically hang up on CPC, silence, busy signal, return to dial tone or time out. If programmed to
auto-answer (DIP switch 1 ON), the E-10A/E-20B will also answer any incoming call.
