Cisco Systems IPMUX-1E operation manual Overview, Versions, IPmux-1 with E1 interface

Chapter 1

Introduction

1.1 Overview

IPmux-1 and IPmux-1E (referred to as IPmux-1/1E) offer a solution for extending traditional E1/T1, ISDN, or POTS TDM services transparently over Packet Switched Networks (PSNs) such as IP, Ethernet, and MPLS networks. The device converts the data stream coming from its user ports into configurable sized IP packets that are extended over the Fast Ethernet Network port, and vice versa. IPmux-1/1E offers end-to-end synchronization for voice/leased line applications. IPmux-1/1E also features a Fast Ethernet user port for data (Ethernet) connectivity to the IP/Ethernet network. Management is performed locally by a terminal, or remotely via Telnet or SNMP.

IPmux-1/1E offers:

•E1/T1 service in IPMux-1 or E1/T1 with echo canceling in IPMux-1E

•ISDN BRI (‘S’) extension in IPmux-1E

•Analog extension (FXS, FXO, or E&M) with optional echo canceling in IPmux-1E.

The IPmux family implements TDMoIP technology to carry TDM transport over IP. IPmux-1E ISDN BRI channels are transported as TDM timeslots, while the analog FXS/FXO/E&M channels are digitized and carried as fractional E1/T1 with CAS.
