General Safety Instructions The following instructions serve as a general guide for the safe installation and operation of telecommunications products. Additional instructions, if applicable, are included inside the manual. Safety Symbols This symbol may appear on the equipment or in the text. It indicates potential safety hazards regarding product operation or maintenance to operator or service personnel.
Handling Energized Products General Safety Practices Do not touch or tamper with the power supply when the power cord is connected. Line voltages may be present inside certain products even when the power switch (if installed) is in the OFF position or a fuse is blown. For DC-powered products, although the voltages levels are usually not hazardous, energy hazards may still exist.
The maximum permissible current capability of the branch distribution circuit that supplies power to the product is 16A (20A for USA and Canada). The circuit breaker in the building installation should have high breaking capacity and must operate at short-circuit current exceeding 35A (40A for USA and Canada). Before connecting the DC supply wires, ensure that power is removed from the DC circuit. Locate the circuit breaker of the panel board that services the equipment and switch it to the OFF position.
When using shielded or coaxial cables, verify that there is a good ground connection at both ends. The grounding and bonding of the ground connections should comply with the local codes. The telecommunication wiring in the building may be damaged or present a fire hazard in case of contact between exposed external wires and the AC power lines. In order to reduce the risk, there are restrictions on the diameter of wires in the telecom cables, between the equipment and the mating connectors.
FCC-15 User Information This equipment has been tested and found to comply with the limits of the Class A digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.

Chapter 1 Introduction 1.1 Overview FOM-E3/ETH and FOM-T3/ETH are fiber optic modems for transmission of 10BaseT or 100BaseT signals over E3/T3 services via multimode or single mode fiber optic media. Product Options Model Options • FOM-E3/ETH: 10/100BaseT over E3 fiber optic services • FOM-T3/ETH: 10/100BaseT over T3 fiber optic services. Power Options • AC power supply: 100 to 240 VAC • DC power supply: 20 to 72 VDC.
Chapter 1 Introduction Installation and Operation Manual Features Ethernet Interface The Ethernet interface of the FOM-E3/ETH and FOM-T3/ETH modems is a high performance self-learning Ethernet bridge module, fully compatible with IEEE 802.3/Ethernet V.2, IEEE 802.1p standards. It also supports the relevant parts of the IEEE 802.1q standard, enabling VLAN applications. The Ethernet interface provides one LAN connection, which can be either 10BaseT (UTP) or 100BaseT (UTP), both with VLAN tagging support.
Installation and Operation Manual Chapter 1 Introduction Alarms When FOM-E3/ETH or FOM-T3/ETH detects that the bit error rate of the signal received from the optical interface is 10-6 or worse, the modem transmits an "All 1s" signal (AIS) to the optical interface. When an AIS is detected at the optical interface, the modem transparently converts the signal and alerts the user via front panel LEDs and the alarm relay port.
