Digital Voice Systems Net-2000 Specifications page 2

Each Net-2000™ converts the input analog
speech into digital speech samples,
encodes the speech using the selected
AMBE Vocoder mode and then send the
®
compressed bit stream out as UDP packets
over the Ethernet interface. Simultaneously,
the compressed bit stream of UDP packets
from the other Net-2000™ is read in from
the Ethernet interface and decoded back in
to digital speech samples. The decoded
samples are converted back into analog
speech via the AIC-10 codec whose output
is sent to both the handset and line-level
output connections.
Alternatively, the Ethernet interface can
connect directly to a Local Area Network
(LAN). This configuration can be used to
create a real-time Ethernet based vocoder
communication system or to record /
playback of files using a PC. Being able to
encode/decode files stored on a PC makes
the Net-2000™ ideal for compressed-voice
storage applications or non-real-time testing
and evaluation.
Initial set-up of the Net-2000™ is fast and
straightforward thanks to its Ethernet
network connection. It is equipped to
handle IP address information from a DHCP

server when available on the LAN.
Alternatively, the Net-2000™'s RS-232 serial
port can be used via telnet as a console
terminal to allow low-level network setup
and selection among the various input and
output audio interfaces.
The Net-2000™ is controlled via PC
connected through the RS-232 or Ethernet
interface. When connected on a LAN —
any PC on the network can use a standard
web browser to configure and control the
unit without requiring custom PC software.
The user-friendly web pages built-into the
Net-2000™ make it easy to select analog
audio interfaces, configure the AMBE
vocoder mode and to establish real-time,
full-duplex communication across the
Ethernet or RS-422 connection. In addition
to the control, the web pages display
information about network settings,
operating mode and system status. Since
the Net-2000™ uses Ethernet, its web page
can even be accessed over a wireless
network through a wireless notebook or
tablet PC.
