Chapter 1. Introduction
Thank you for choosing the
FMUX04
. If you would like to skip right to the installation and
configuration of the Multiplexer, proceed to Chapters 2 and 3.
This manual is used to explain the installation and operating procedures for the
FMUX04
, 4
Port Fiber Optical E1/T1 Multiplexer, and present its capabilities and specifications. This
manual is divided into 5 Chapters, the Introduction, Installation, Operation, Loop Back
Testing and SNMP chapters. The Appendix includes the pin assignments of special cables
and gives further information on options for placing the device in service.
The divisions of the manual are intended for use by personnel to answer questions in general
areas. Planners and potential purchasers may read the Introduction to determine the suitability
of the product to its intended use; Installers should read the Installation Chapter and the
Cabling Specification Appendix; Operating Personnel would use the Operations Chapter to
become familiar with the line cards and settings. Operating Personnel and Network
Administrators should read the chapters on loop back testing and on SNMP to become
familiar with the diagnostic capabilities, network settings and management strategies when
the optional SNMP card is installed.
1.1 General Description
The FMUX04 is a 1U (1.75") high standalone or half rack mountable E1/T1 multiplexer over
fiber link designed for cost effective applications. The FMUX04 provides an economic
optical connection solution in low-density E1 or T1 installations such as between remote
offices, where multiple high speed synchronous TDM (Time Division Multiplexing)
communications are required over a single fiber pair. By utilizing a fixed channel design, the
unit is extremely cost effective and provides quick return on investment.
1.2 Functional and Feature Description
The standard unit is a standalone chassis with local control (DIP switch settable or via
Console port) and ordered with either AC or DC power. The appropriate optical transceiver
may be selected when ordering to support multi-mode or single-mode fiber cable operation,
with a variety of power and connector options including ST™, SC, FC, or LC. WDM (Wave
Division Multiplexing) optical transceivers are also available to provide bi-directional
transmission on a single fiber to reduce cost when using leased fiber links. The range of
transmission for optical connection is from 2Km (for multi-mode) up to 120Km (single
mode).
SNMP (for local and remote management purposes) and FXS Order Wire are options that
may be factory ordered or may be ordered separately for later installation in the unit. The
FMUX04
is available in three power supply configurations. Depending on the model, power
may be derived from single AC 100~240VAC, single DC +18~36VDC, or single DC
+36~72VDC power source. The
FMUX04
provides all interface connections on the rear
panel. There are 4 channel connections for ITU-T G.703 E1/T1 on 4 x RJ-45 (USOC RJ-48C)
or 8 x BNC connectors. Each Channel connector provides an individual channel of E1 or T1,
depending on the unit's configuration.
