FCC Notice
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed in accordance with the instruction manual, may
cause harmful interference to radio communication. Operation of this equipment in a
residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at the user’s own expense.
CE Declaration of conformity
This equipment complies with the requirements relating to electromagnetic compatibility,
EN 55022 Class A for ITE and EN 50082-1. This meets the essential protection
requirements of the European Council Directive 89/336/EEC on the approximation of the
laws of the Member States relating to electromagnetic compatibility.
Rack Mount Installation Instruction
(a) Elevated Operating Ambient Temperature:
If installed in a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than room ambient. Therefore,
consideration should be given to installing the equipment in an environment
compatible with the manufacturer’s maximum rated ambient temperature.
(b) Reduced Air Flow
Installation of the equipment in a rack should be such that the amount of air flow
required for safe operation of the equipment is not compromised.
(c) Mechanical Loading
Mounting of the equipment in the rack should be such that a hazardous condition is
not achieved due to uneven mechanical loading.
(d) Circuit Overloading
Consideration should be given to the connection of the equipment to the supply
circuit and the effect that overloading of the circuits might have on overcurrent
protection and supply wiring. Appropriate consideration of equipment nameplate
ratings should be used when addressing this concern.
(e) Reliable Earthing
Reliable earthing of rack-mounted equipment should be maintained. Particular
attention should be given to supply connections other than direct connections to the
branch circuit (e.g., use of power strips).
Trademarks
All brand, company and product names are trademarks or registered trademarks of their
respective companies.

Chapter 1 Overview
This chapter gives an overview of the LevelOne VOI-8000, Internet Telephony Gateway
(ITG), and a detailed description of its front panel and back panel.
1.1 Features
The VOI-8000 is a cost-effective and highly reliable analog Voice over IP (VoIP) Gateway
that offers toll quality voice and real-time fax data over IP networks. With its embedded
architecture, the gateway is ideal for VoIP applications associated with Remote Office and
Branch Office (ROBO) environments. With its built-in user-friendly interface, the gateway
may be installed easily and conveniently to yield immediate cost savings. One Internet
Telephony Gateway supports up to eight voice or Fax communications simultaneously.
Implemented with an efficient Real-Time Operating System (RTOS) and flash memory, the
VOI-8000 provides upgradeable capabilities, so it may be programmed with updated
firmware locally or via the network at any time. It comes equipped with remote management
capabilities, configurable signaling to work with PBX, KTS, and/or telephone. The VOI-
8000 utilizes advanced VoIP related technology. It includes various voice coders and fax
algorithms, echo cancellation, Voice Activity Detection (VAD) , Comfort Noise Generation
(CNG) , and lost packet recovery algorithms.
1.2 Networking Protocols
The VOI-8000 supports several industry-standard networking protocols required for voice
communication. The following table describes these protocols.
Networking Protocol Description
Internet Protocol (IP) IP is a messaging protocol that addresses and sends packets across
the network. To enable IP protocol, the VOI-8000 must have a Real
IP address, subnet, and gateway assigned to it.
Voice over IP Protocol
(VoIP) VoIP enables the VOI-8000 to transfer voice communications over an IP network. The VOI-8000 employs ITU-T H.323 protocol for
setting up call with one another.
Trivial File Transfer
Protocol (TFTP) TFTP allows you to transfer files over the network. The VOI-8000 implements a TFTP client allowing you to download new revision
firmware from a TFTP server. The TFTP client requires a TFTP
server in your network.
Real-Time Transport
(RTP) RTP is a standard for transporting real-time data over IP network. The VOI-8000 uses RTP protocol to send digitized and compressed
voice packets.
