Section 1. Introduction - Overview of Product
1.1 Introduction
The RFL™ eXmux® is a next generation substation hardened IP Access Multiplexer
engineered to seamlessly transport Voice, serial and Ethernet Data communications over
Ethernet networks, providing the flexibility of backward compatibility with legacy devices and
forward compatibility with Ethernet devices on the same communications platform. The RFL™
eXmux® uses the latest TDM over IP technology and an integrated Carrier Grade Ethernet,
which allows the unit to support legacy interfaces such as T1/E1, RS-232, RS-530/422, V.35,
X.21, C37.94, and various voice interfaces, along with native IP solutions including various
Ethernet services. The eXmux® 4500 is a 5U high unit that offers hot-swap capabilities for all
functional Interface Units for use in mission-critical applications.
The RFL™ eXmux® can support any network topology such as linear, star, rings, and mesh
setups. Designed into the RFL™ eXmux®, is a distinctive “Hitless Switching” mechanism that
allows the device to recover from a path failure without losing a single data bit. The simplified
diagram below shows the basic data flow within a network.

1.2 Major Components
The illustration below shows the 4500 RFL™ eXmux® unit. The main components are
shown with a brief description of their function. Internal components are described to give
the operating engineer a brief understanding of how the RFL™ eXmux® functions. The
4500 has a modular design featuring “Hot Swap” capability for easy Interface Unit
replacement without taking down the node.
4500 5U
The Backplane contains slots for the following units.
1. Controller Card
The RFL™ eXmux® 4500 has a removable control card assembly that is accessed from
the rear of the unit. The motherboard functions as a mid-plane between the Interface
units and the mainboard providing “hot swap” control and buffering.
The Controller Card has LEDs (visible from the rear) that provide more information
about the card.
2. SysIO card
The System I/O card provides access to T1/E1 ports, alarm contacts and clock sources.
(See section 8.4 Sys I/O Card for more information)
Because Hubbell Power Systems, Inc. has a policy of continuous product improvement, we
reserve the right to change designs and specifications without notice and as such this policy
applies to the entire document, even when not specifically referenced.

3. Core I/O (Ethernet Switch)
Up to two Ethernet Switch cards each containing:
•Two SFP cages for 10Gb/s Ethernet links.
•Two SFP cages for 1Gb/s Ethernet links.
•Two RJ 45-type jacks for 1Gb/s Ethernet links.
(See Section 3.7 Core I/O Card).
