Chapter 1 Introduction
1-1 Functional Description
The CTC Union’s FMUX03 is a fiber optical multiplexer that integrates 4/8/16
channels of E1 signal into a single optical data stream. It extends the transmission
distance up to 80 kilometer. With the optional secondary optical link, FMUX03
provides 1+1 optical line protection. In addition, FMUX03 also provides the
standard SNMP interface for Network Management, using Ethernet and PPP ports to
connect to central office. User can monitor the FMUX03 through built-in In-band
operation channel to reach a remote terminal. Moreover, FMUX03 simplifies testing
and maintenance with order wire, allowing communication between local and remote
maintenance crews. The FMUX03 provides the telecommunication company a
multipurpose and easy to use high quality fiber optics multiplexer.
 The use of FMUX03 with the Smart Agent network interface for ease of network
connectivity.
 Provides both 10/100 Base-T and PPP interface to connect SNMP Network
Management center interface system.
 Optional secondary fiber link offers 1+1 line auto protection to insure network
quality and efficiency.
 In-band operation channel provides the ability to configure, test, and monitor
system status and alarm from both local and remote terminal. FMUX03 offers
real-time monitoring of the transmission quality to meet the demands of high
quality communication.
 E1 signal control calculates error in Path and Line
 The fiber optical interface of E1 communication system complies with the
requirement of ITU-T regulatory standards.
 Order wire to assist with remote maintenance, configuration, and testing
 Provides the parity error count for optical interface performance monitoring.
 Operating from dual AC /DC(selectable) power module (co-exist on FMUX03),
backup power supply is available.
 Mountable on either 19-inch or 23-inch rack.

1-2 Applications of FMUX03
FMUX03 is mainly used to extend the transmission distance of E1 signal by
multiplexing four individual E1 channels into a single optical data stream. As
illustrated below, there are three main applications for the use of FMUX03:
 Application 1: FMUX03 integrates 4/8/16 E1 channels into a single optical data
stream.
 Application 2: FMUX03 can connect rDSLAM to a remote Central Office
 Application 3: FMUX03 can connect a Base Station (BS) to a Base Station
Control (BSC).

Chapter 2 - Installation
2-1 Description
This chapter provides the information needed to install FMUX03. It is important to
follow the installation instruction to insure normal operation of the system and also to
prevent damage due to human error.
2-2 Unpacking
If there is a possibility for future relocation of the FMUX03 unit, please save the
cartons and protection packaging material. The following items are shipped with
your FMUX03:
 One FMUX03 User’s Manual
 One FMUX03 Unit
 Depends on what was ordered, either DB-25 wire wrapped adaptor or DB-25
Mini Terminal Block
Please carefully unpack and inspect the unit and accessories for damaged and missing
parts. Contact our nearest sales representative or our company directly if you suspect
any damaged or missing parts. Improper handling during shipment may cause early
failure.
2-3 Site Requirements
The FCC requires telecommunication equipment to withstand electrical surge that
may result from lighting strikes. FMUX03 has been tested and found to comply with
the FCC requirement. Users should follow the precaution below to insure the safety
and minimize the risk of damage to the equipment:
 Make sure that the power outlet is properly grounded. Please refer to article 250
of the National Electrical Code (NEC) Handbook.
 Proper grounding should include a minimum of:
1) A grounded rod buried outside the building at least 8 feet (2.44 meters) deep.
2) It is preferred that the building uses metal water pipe and cooper connector at
the joint.
2) Any device connected to FMUX03 either directly or indirectly should use the
same set of power outlet.

FMUX03

2-4 Site Selection
For best performance, install the FMUX03 within 50 feet (656 meters) from the data
terminal equipment and 6 feet (1.83 meters) from the AC power outlet. To allow
easy access to the equipment, leave at least 36 inches (90 cm) clearance in front and at
least 4 inches (10.2 cm) at the rear.
To avoid overheating, leave at least 1 inch (2.5 cm) on either side of FMUX03. Also,
do not stack another equipment on top of FMUX03.
2-5 AC or DC Electrical Outlet Connection
For safety and to prevent damage to FMUX03, make sure that the power requirement
matches those of your electric outlet. Connect power to FMUX03 and power on the
equipment.

FMUX03 provides easy to use LCD control for easy configuration, maintenance, and
testing. Button functions are as follows:
Menu select
▲Go back to the upper level of the menu
▼“Enter” key to go to a sub-menu
4-1 Profile
Download and Save Profiles:
If the user selects the factory default profile, the system will restart before
downloading the factory default profile.
User can configure E1 Line Code(HDB3/AMI), and Loopback test. After selecting
the “user_defined” option, the system will automatically restart. The system will
then download the user custom profile.
Modify Password:
To prevent unauthorized login, user must enter a set of password to login to the
system.
The password for FMUX03 is a combination of the buttons below, from left to right:
