Overview 1-1
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.
