i-Series

Gateway

The i-Series Gateway is a high performance unit that resides at the corporate voice system and terminates up to twelve remote users from any combination of NEC remote voice solutions including:

i-Series Branch Extender

i-Series Single IP Extender

The i-Series Gateway operates in Remote Voice Protocol over IP (RVPoIP)™ mode to an IP network or serial Remote Voice Protocol (RVP)™ mode over a traditional network.

 

Product Overview

With NEC’s i-Series Gateway, your remote workers can now enjoy all the features of your corporate PBX, wherever they are located. That’s because the i-Series Gateway extends all the capabilities of your KTS/PBX to remote employees over circuit or packet networks.

The i-Series Gateway can be configured to operate in either a managed IP packet network or a point-to-point synchronous WAN environment over traditional networks. In a traditional WAN environment, up to two i-Series Branch Extenders can connect into the i-Series Gateway with Remote Voice Protocol (RVP)™ using voice signal encapsulation in HDLC packets over a serial port connection.

 

Remote Voice Protocol Over IP (RVPoIP)™

To extend remote voice capability over a managed IP network, simply install an i-Series Gateway at your corporate site and then choose a combination of remote IP client units to meet your needs. Up to 12 ports can be terminated at the i-Series Gateway. Branch offices, teleworkers and remote call center agents can be connected using standard IP network termination devices such as IP routers and DSL or cable modems.

As long as the IP network can be managed to ensure sufficient bandwidth and Quality of Service (QoS), the NEC solution will deliver high quality voice.

You can extend full corporate PBX capabilities over IP networks making voice and data convergence a reality.

A Remote Voice Protocol converts digital voice and phone signals into highly efficient data packets. Sophisticated software features include G-165 compliant echo canceller enhanced with robust double-talk performance, manufacturer provided PBX protocols and a range of industry standard voice compression options.

 

Management Features

NEC’s business voice solutions have been designed for operational simplicity. All of the systems configuration, management and administrative and diagnostic functions may be managed from the i-Series Gateway using a serial connection, Telnet or an inband network connection from a remote client. This flexibility allows you to maximize your company’s system administration resources and lower the operating costs.

 

Key Benefits

Flexibility

Mix and match Extender modules for a total of up to 12 ports. This i-Series Gateway supports up to two i-Series Branch Extender modules for branch offices. Configure the i-Series Gateway to operate in managed IP network (Layer 3) or in traditional circuit switched and frame relay (Layer 2) environments.

 

Increased Productivity

Remote employees are able to use the same full featured digital telephones and have access to corporate PBX functions, like voice mail, call accounting system, unified messaging and ACD systems.

 

Network Efficiency

A choice of network topologies and variable compression rates minimize communications cost. Leverage IP data network infrastructure for both voice and data traffic.

 

Ease-of-Use

Simple installation process. Easy-to-use configuration tools enable management of remote units from a central location.

 

Investment Protection
