DVA-1003B

Three Channel

Digital Voice Announcer

July 7, 1998

3 Channel Non-Volatile Digital Voice Announcer

with Remote Recording and Transfer Capabilities

The DVA-1003B is a fully professional, cost-effective three port digital voice announcer,
specifically designed for ACD/UCD, auto attendant, call intercept, night messaging information
provider and other PABX and Centrex announcement applications.

The DVA-1003B will increase call handling capacity by answering incoming calls on demand,
or on the first ring, and automatically adjusts the announce time to the length of the outgoing
message. The DVA-1003B will disconnect on CPC and provide instant “rewind” for the next
caller.

Each of the DVA-1003B’s three channels is factory equipped with 16 seconds of non-volatile
recording memory, expandable to 1 full minute per channel with Viking’s ERAM-60 expansion
kits.

Wire each channel of the DVA-1003B with either or both the 4 wire E&M jack and/or the 2 wire ring trip jack as
shown above. When using the 4 wire E&M, the ring trip interface may be used for remote programming. The E&M
functions will resume when programming is finished.

Note: The DVA-1003B requires a 24 hour unswitched 115V AC outlet. To protect the internal electronics, the
installation of a surge protector is recommended.

B. Installing the ERAM-60

Important: Electronic components are sensitive to static

electricity. Personnel and the work area should be grounded
before handling.

F. Recording/Programming Remotely From a Touch Tone Phone

1. Accessing the Remote Recording/Programming Mode

Note: Each channel is programmed separately.

a. Call the C.O. line or analog PABX/KSU extension connected to the 2 wire ring trip port.
b. When that channel of the DVA-1003B answers, enter a Q.
c. After the recording stops, enter your security code (factory set to 845464). Two beeps should be heard.
d. You are now in the remote recording/programming mode.
e. A valid entry will be signaled with two beeps. An invalid entry will be signaled with three beeps.

2. Remote Recording

a. After entering the programming mode, enter Q1, wait for the start tone.
b. Begin recording your message. Enter any Touch Tone to stop the recording.
c. To review the announcement, enter Q3, or hang-up and wait 20 seconds for the unit to disconnect, then call in.

3. Programming the Ring Delay Remotely

a. After entering the programming mode, enter the desired ring delay (0 - 9).
b. Enter #45.

4. E & M Timing

The Beginning Of Message and End Of Message pulse width is factory set to 600ms. This may be programmed
from 100ms (Touch Tone 1) to 900ms (Touch Tone 9). Enter 1 - 9, #46.

5. Repeat Announcement

When in programming enter 01-99, #44 to have the announcement play from 1 to 99 times.

6. Changing the Security Code

It is recommended that you change the security code from the 845464 factory setting to your own personal 6

4

digit number. To change the security code, enter 6 digits #47.

Note: The security code cannot contain a Q or #.

7. Transfer Option

When in programming enter the extension number, up to 16 digits, followed by #00. Dial QQ for a Q, Q# for a #
and Q7 for a four second pause.

Note: See Operation for phone system requirements.

8. To Leave the Remote Programming Mode

Simply hang-up and that channel of the DVA-1003B will time-out and disconnect.

A. Ring Trip Interface

1.

Standard - Any ringing C.O. line or analog PABX/KSU station will be answered after the programmed ring delay,

given the announcement and released. That channel of the DVA-1003B is then immediately ready to answer the
next incoming call.

2.

Announcement Repeat Option - An announcement may be programmed to be repeated up to 99 times. When

in programming, enter the announcement repeat value (01 - 99) followed by #44. The announcement will then
be repeated up to the programmed value, or until the caller hangs up and the DVA-1003B detects a CPC signal
from the C.O. line. Callers that do not hang-up may then be transferred to another extension of the phone
system (see Transfer Feature below).

Transfer Feature - A ringing C.O. line will be answered after the programmed delay, hear the announcement,

3.

and then be transferred to another extension of the phone system. This feature may only be used on analog
PABX/KSU stations or Centrex lines with “blind” hookswitch-flash transfer capabilities. Specifically, this requires
that a basic “2500” set can perform a hookswitch flash transfer and ring another extension, which is not required
to answer before the first extension releases the call. When in programming, enter the number of the extension
to be transferred to (up to 16 digits) followed by #00. To disable this feature, when in programming simply enter
#00 without any station prefix.

Use Ring Trip Interface. Connect T & R to pins 3 & 4 of the CO/PABX
line jack.

Operation

B. Four Wire E & M

The 600 OHM E & M jacks provide a 600 ohm “Dry” output. Refer to E & M protocol settings and timing on pages 3
and 4, and the PABX table on pages 5 and 6 for proper operation.
