RLH Analog Phone & Data
Mux Over Fiber System
16 CHANNEL VOICE WITH DATA
OVER FIBER OPTICS
Introduction
The RLH 16 channel RLH Analog Phone & Data Mux Over Fiber
System provides a comprehensive method of multiplexing
analog phone (POTS) channels over a single pair of multimode
or single mode fibers in dual fiber models, or a single fiber in bi-
directional fiber models. This compact single rack unit (1RU)
system solves the problem of adding POTS lines when available
fiber is limited, reduces equipment space, and lowers overall
equipment costs.
The system also includes four 10/100M Ethernet ports for LAN
interconnection, and two channels of RS-232 or RS-422/485
data ports. 2/4-wire E&M/Analog Data/Audio ports are available
options. All ports operate simultaneously over the fiber optic
cable, and may be used with leased lines to build up private
networks and private telephone networks.

General Safety Practices
Intended Audience
This guide is intended for use by knowledgeable telco/network installation, operation and repair
personnel. Every effort has been made to ensure the accuracy of the information in this guide is accurate.
However, due to constant product improvement, specifications and information contained in this
document are subject to change without notice.
Conventions
Symbols for notes, attention, and caution are used throughout this manual to provide readers with
additional information, advice when special attention is needed, and caution to prevent injury or
equipment damage.
The equipment discussed in this document may require tools designed for the purpose being described.
RLH recommends that service personnel be familiar with the correct handling and use of any installation
equipment used, and follow all safety precautions including the use of protective personal equipment as
required.
Caution - Severe Shock Hazard
• Never install during a lightning storm or where unsafe high voltages are present.
• Active phone lines may carry high DC voltages. Use caution when handling copper wiring.
• The chassis must be grounded using the ground lug to reduce the risk of damage from lightning.
Warning
The intra-building port(s) of the equipment or subassembly is suitable for connection to intrabuilding or
unexposed wiring or cabling only. The intra-building port(s) of the equipment MUST NOT be metallically
connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as
intra-building interfaces only (Type 4 ports as described in GR-1089-CORE, Issue 4) and require isolation
from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to
connect these interfaces metallically to OSP wiring.
Guidelines for handling terminated fiber cable
• Do not bend fiber cable sharply. Use gradual and smooth bends to avoid damaging glass fiber.
• Keep dust caps on fiber optic connectors at all times when disconnected.
• Do not remove dust caps from unused fiber.
• Keep fiber ends and fiber connectors clean and free from dust, dirt and debris. Contamination will cause signal loss.
• Do not touch fiber ends.
• Store excess fiber on housing spools or fiber spools at site

FXO/CO (Central Office) Side Unit
The FXO/CO side unit provides the electrical-optical interface between PSTN or PABX 2-wire copper
POTS lines, Ethernet devices or LAN, RS-232/422/485 data devices and the optical fiber cable.
Redundant powering options include 115/240VAC and/or 12VDC, 24VDC, 48VDC local power.
Note: The DC power terminals are polarity sensitive. Observe the and terminals on the DC input terminal.
FXS/Sub (Subscriber Side) Side Unit
The FXS/Sub side provides the electrical-optical interface between the copper 2-wire POTS line devices
(phones, fax, modem), Ethernet devices or LAN, RS-232/422/485 devices and the optical fiber cable.
Redundant powering options include 115/240VAC and/or 12VDC, 24VDC, or 48VDC local power.
Note: The DC power terminals are polarity sensitive. Observe the and terminals on the DC input terminal.
Note: FXS/Sub units are electrically different from FXO/CO units and cannot be interchanged. Once all
connections are checked, turn the unit ON using the power switch on the front panel.
Note: The FXO and FXS units normally take a few minutes to sync with each other during initial setup or
when power is turned OFF then ON.
See your RLH representative for RS-232 to RS-485 converters, power supplies with redundant power and
battery backup, fiber optic cable, patch panels and other accessories compatible with the POTS Mux
System.

Ringdown Circuit (FXS/Sub Unit to FXS/Sub Unit)
The ringdown circuit requires the use of an FSX/Sub unit at each end. Using this configuration, picking up
a phone at one end will automatically ring and connect the corresponding phone on the other end. This
feature enable the POTS Mux to function as a direct line analog phone system.

The yellow PHONE LEDs on the front panel indicated which analog phone (POTS) lines are being actively
used. E&M/Analog Data models will display active E&M/Analog Data lines in the phone LED status display.
Ethernet RJ-45 Ports
Four Ethernet ports use standard RJ-45 connectors. LED indicators on each port indicate the port
connection and speed. The LINK LED is ON when the port is connected to a LAN or other active link, and
the SPD LED is ON when the port auto-detects 100M speed.

Power Connection
Make sure the power switch on the front panel is OFF. Attach a ground wire to ground lug on the back
panel. The chassis must be grounded using the ground lug to reduce the risk of damage from lightning.
The system is powered by 48VDC and may accept 12 or 24VDC and/or 115/240VAC with the provided
adapter for the specific order. Both inputs may be used at the same time, providing redundant power for
the unit. Once all connections are checked and power is applied, turn the unit ON using the power switch
on the front panel.
Note: The DC power terminals are polarity sensitive. Observe the and terminals on the DC input terminal.
Optical Ports
The optical ports may be equipped with ST, SC or FC fiber connectors. A fiber pair is required for
operation with dual fiber models, TX is the signal output side and RX is the signal input side. Bi-directional
single fiber models combine input and output, and require only a single fiber.
DIP Switch
The DIP switches are for factory settings and testings and should not be changed by the end user. For
proper operation set all the DIP switches must be set to the OFF, or UP position.
Analog Phone Ports
The POTS ports use the center 2 pins of RJ-45 connectors. Use the included adapter connectors to
attach RJ-11 connectors to the POTS Mux.
Note: All ports are included on each unit, but only the ports that are installed on your unit are active, the
unused ports are inactive. Refer to the product label to see the POTS channel capacity on your unit.
