This document gives an overview of the Elite Gateway* 2 & 4 port desktop version and a detailed description of its front panel and rear panel.

Features
The Elite Gateway 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.

Implemented with an efficient Real-Time Operating System (RTOS) and flash memory, the Elite Gateway 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 Elite Gateway 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.

Networking Protocols
The Elite Gateway 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 Elite Gateway must have a static IP address, subnet, and gateway assigned to it. Voice over IP Protocol (VoIP) VoIP enables the Elite Gateway to transfer voice communications over an IP network. The Elite Gateway 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 Elite Gateway 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 Elite Gateway uses RTP protocol to send digitized and compressed voice packets.

Front Panel
The front panel of the Elite Gateway contains a push button and LED indicators. The following figures illustrate the front panel of the Elite Gateway.

(Heartbeat LED) LAN ACT 100M   LNK COL   Green Green   Green Green   On On Off On On   Data is presented on LAN. The gateway is connected to LAN at 100Mb/s. The gateway is connected to LAN at 10Mb/s. The gateway is connected to LAN. Data collision is occurring on the network connection. Line Channels 1-4 Green     Off On Blinking The line is idle. The line is being used. The line is ringing.

Reset Button
There is a push button located behind a small hole next to the SYSTEM LED. This button allows you to reset the Elite Gateway or force the Elite Gateway to enter firmware upgrade mode.

To reset the gateway, push a small, stiff object like a paper clip into the hole until the SYSTEM LED stops blinking, and then release the button.

Powering on the gateway while pressing down the button for 5 seconds forces the Elite Gateway to enter download mode

Rear Panel
The rear panel of the Elite Gateway has two FXS ports for the 2 port version of the Elite Gateway, or four ports (2 FXO and 2 FXS) for the 4 ports version of the Elite Gateway. The telephony interface ports may be connected to telephony devices, such as PBX, KTS, and telephone sets. In addition to the telephony interface ports, there is a power adapter connection hole on the rear panel.

LAN / Console Ports
The Elite Gateway is equipped with an Ethernet interface with 10/100 Mbps auto-negotiation capability. The Ethernet interface port is located on the rear panel. In addition to the Ethernet interface port, there is a 9-pin RS-232 interface port on the rear panel.
