Chapter 1 Introduction

1.1 Overview

IPmux-16 is a modular TDMoIP gateway. IPmux-16 modules enable up to 16 E1

or T1 circuits to be extended over IP networks. The device converts the data

stream coming from the E1 or T1 ports into configurable-sized IP packets that are

transported over the Ethernet port and vice versa. IPmux-16 offers end-to-end

synchronization for TDM applications and large buffers, to compensate for the

delay variation inserted by the network. The device can be used to extend E1 or

T1 services over high speed IP/Ethernet backbones for both Metropolitan Area

Network and corporate applications. IPmux-16 can be managed locally via an

ASCII terminal or remotely via Telnet or RADview (RAD’s SNMP-based network

management application).
