Branch Extender

"Remote Employees won't feel remote anymore"

If you’ve ever worked in a remote office, you know why they call them remote. Remote employees usually have had to settle for second-rate services because the technology was not available or the costs of duplicating resources were too high.

Now, imagine providing better services to your branch employees and your customers with minimum additional investment.

NEC’s Distributed Voice Solutions affordably extends the features and functionality of existing corporate voice systems to:

  • Branch Offices
  • Remote Call Center Agents
  • Telecommuters
  • Mobile Workers

across traditional and next-generation networks.

 

Product Overview

With NEC’s i-Series Branch Extender for branch offices, off-premise workers can now enjoy the features of the corporate KTS/PBX, from wherever they are located. No more feeling of seclusion from co-workers and corporate resources.

The i-Series Branch Extender delivers quality voice over circuit-switched and managed packet networks.

The i-Series Branch Extender supports two proprietary protocols: Remote Voice Protocol (RVP)™ and Remote Voice Protocol over IP (RVPoIP)™. One or more i-Series Branch Extenders can be terminated at one i-Series Gateway located at the corporate office. The i-Series Branch Extender is available in 8-port and 12-port configurations.

A proprietary remote voice protocol turns digital voice and phone signaling into highly efficient data packets. Sophisticated software features include a G.165-compliant echo canceller enhanced with extremely robust double-talk performance and a range of industry standard voice compression options.

i-Series Branch Extender for branch offices enables you to provide full corporate PBX capabilities over an existing data network, making voice and data convergence a reality. The i-Series Branch Extender has been designed for operational simplicity, freeing branch employees from administrative tasks. All of the system’s configuration, operation, and administrative and diagnostic functions may be managed using a serial connection, Telnet, dial-up modem or an inband network connection from an i-Series Gateway. This flexibility allows you to maximize your company’s network administration resources and lowers operating costs.
