Chapter 1
Introduction
This chapter provides an overview of features and capabilities.
The DCB nalog Voice dapter-Ethernet ( V -E) is used in pairs to provide a high quality compressed
voice channel plus an asynchronous serial data channel through a single composite serial or ethernet data
link. The serial network may be synchronous or asynchronous, using leased line modems, radio links, or
digital data service. synchronous terminal devices may be terminals, printers, computer ports or other
asynchronous devices. The voice channel may be connected to standard analog telephone sets, PBXs, key
systems, radios, etc. The ethernet network link may be any IP connection, including the Internet, satellite,
wireless, and broadband connections.
The asynchronous data port is configurable for speeds up to 57,600 bps. Serial network speeds may be as
high as 230.4 Kbps asynchronous or 256 Kbps synchronous. Depending upon the voice quality desired, the
voice channel can be configured for bit rates between 2250 and 9600 bps or DPCM (32K), PCM (64K).
The V -E is configured via a USB Setup port using a PC with terminal emulation software or using a
web browser connection. Configuration settings are maintained in non-volatile memory.
dditional features of the V -E include:
User configurable voice rate and jitter delay.
vailable with an optional built-in 12 VDC, 24 VDC or 48 VDC power supply.
Industrial temperature rating of –40C to +85C
Ethernet IP connectivity over any Internet connection.
Rack mount options.
FXS/FXO, 4-wire E&M, or Push-to-Talk interfaces
Applications
The V -E provides quality voice links at minimum bandwidth. While low-bit-rate voice is adequate for
many uses, some audio applications require PCM or DPCM encoding. V -E is the rare product that
provides both low-bit-rate as well as high quality DPCM/PCM options.
•Utility substations
•Office to home analog extensions
•High quality udio over data links for remote voice logging and transmitter control
•Two-way radio audio over slow speed data links
•Gas and oil production, pipelines
•Remote radio dispatch operations
•Phone extensions over wireless and satellite links
•"Hoot 'n Holler" remote public address/ intercom systems using data connections

Configuration
Other Features
Multiplexed data port
The V -E contains an additional asynchronous interface that is multiplexed along with the voice to
corresponding remote V units. This is sometimes used for remote transmitter control, cascading an
additional V unit, or remote control of a computer or controller.
Flexible Configuration Options
While the V -E is normally configured using a web browser, it may also be configured with a local
terminal (or PC with terminal emulation) using either of two serial connection methods. A limited set of
configuration items may also be accessed with a telnet client.
Voice Interfaces
The V -E is available with FXS/ FXO, 4-wire E&M or only push-to-talk (PTT) audio interfaces. PTT is
included with the FXS/FXO and E&M units. The interface is specified at the time the unit is ordered. The
PTT audio interface is supplied with a microphone and speaker for PTT only orders, and as an add-on item
for FXS/FXO and E&M units. The speaker circuit contains a .25 watt amplifier for local P applications.
Voice Quality
The V -E provides exceptional compressed voice quality at speeds ranging from 2400 to 9600 bps. The
compressed voice is based on the same chip set used for Project 25 (P25) radio interoperability. This is a
voice chip set that has a very long market life, which translates to a long market life for the V -E. V -
E voice choices also include 64K PCM. The choice of PCM makes the V -E suitable for applications
that require tone control, such as links to radio transmitters.
Security Features
Configuration access may be locked down to individual IP addresses. User names and passwords may be
required for configuration, and the web server, telnet server, and SNMP server may be disabled for
additional configuration security on the ethernet enabled models.
Extensive audio configuration parameters
In addition to the voice digitization rate, individual settings for each unit include preamp gain, input gain,
output gain, jitter buffer, and E&M signaling.
Rugged, Industrial Quality
With various industrial rated power supply options and industrial temperature rating of -40 to 85 C, V -
E is at home in the field or office.

Package Contents
You should find the following items packed with the V -E:
External 100-240V C power supply (if appropriate)
Manual on CD
Warranty, maintenance contract and repair information in the CD manual
Modem to Composite cable (black) for connecting the V -E to an external modem or
DSU/CSU
USB cable for connecting the V -E setup port to a PC for configuration
If any of the above are missing, contact your dealer immediately.
Configuration Software Re uirements
The V -E requires a modern web browser for configuration. The PC should be configured with a
compatible IP address. The default V address is 192.168.0.1.
Configuration of the V -E through a serial port requires a terminal emulation program on the PC, and
use of the USB connection (with the supplied USB cable) additionally requires compatible USB drivers be
installed on the PC. The latest drivers may be downloaded from
http://www.ftdichip.com/Drivers/VCP.htm.

Configuration
AVA-E Hardware
Front Panel
The front panel contains LED indicators, a microphone connection, USB configuration port, synchronous
data port, Synchronous network port, and Ethernet network port.
Front Panel LED Indicators and Connections
Indicators
POWER – is ON when the V -E is connected to power.
Tx – Transmit Data is being sent out the network port
Rx – Receive Data is being received on the network port.
Data – TX or RX Data is present on the ASYNC DATA port.
Err – Flashes for data port errors (framing, overrun, parity) and for network receive block
checksum errors.
OH – Flashes when the voice port is active.
CD – On when DCD is present on network port.
Sync – On when network port is set for synchronous operation. Off when serial network port
is set for asynchronous operation, or when L N port is used.
SU – Flashes when DIP switch 2 is up and unit is reset. This maps the setup functions to the
ASYNC DATA port on the front of the V -E.
There are also two LED indicators on the Ethernet L N connector. Yellow for 10M ethernet
and Green for 100/1000 Mbit ethernet.
Connections
•Microphone Connection for local microphone
•USB Configuration connection (used for serial configuration)
•synchronous RS-232 data connection
•Synchronous or asynchronous RS-232 network connection*
•Ethernet L N network connection*
*Note that either the RS-232 network or the Ethernet L N network may be used, but not both.

Rear Panel
Real Panel Connections and Switches
Connectors
•Power Connector: Either a 6VDC coaxial connector for the C powered units or a multi-
pin screw connection connector used for DC powered units.
•Two pin screw connection for an optional audio speaker ( udio Output).
•RJ-45 E&M connection.
•RJ-11 FXS/FXO connection.
For details on configuration of the speaker, E&M and FXS/FXO options, refer to the Voice
Settings section.
Switches
Four DIP switches are accessible on the rear of the unit. Their functions are as follows:
Switch 1 – not used
Switch 2 – If up when unit is reset, the RS232 ASYNC DATA port becomes the setup port.
Switch 3 – Factory use only.
Switch 4 – not used
There is also a RESET switch accessible through a small hole in the rear panel.
NOTE
The V -E is not operational while in switch 2 setup mode. If switch
2 is used for setup, connect the PC Com port to the V -E using the
cable shown in the Cables section of this document, (Data Port to a
PC Com Port). Set the PC terminal emulator for 9600, 8,N,1 and no
flow control. Set switch 2 UP and press reset to enter setup mode. To
exit setup, put switch 2 DOWN: This will cause the unit to reboot and
be ready to resume normal operation.
