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.
Before working on equipment connected to power lines or telecommunication lines, remove jewelry
or any other metallic object that may come into contact with energized parts.
Unless otherwise specified, all products are intended to be grounded during normal use. Grounding is
provided by connecting the mains plug to a wall socket with a protective earth terminal. If an earth lug
is provided on the product, it should be connected to the protective earth at all times, by a wire with a
diameter of 18 AWG or wider. Rack-mounted equipment should be mounted only in earthed racks
and cabinets.
Always make the ground connection first and disconnect it last. Do not connect telecommunication
cables to ungrounded equipment. Make sure that all other cables are disconnected before
disconnecting the ground.
Connection of AC Mains
Make sure that the electrical installation complies with local codes.
Always connect the AC plug to a wall socket with a protective ground.
The maximum permissible current capability of the branch distribution circuit that supplies power to
the product is 16A. The circuit breaker in the building installation should have high breaking capacity
and must operate at short-circuit current exceeding 35A.
Always connect the power cord first to the equipment and then to the wall socket. If a power switch is
provided in the equipment, set it to the OFF position. If the power cord cannot be readily
disconnected in case of emergency, make sure that a readily accessible circuit breaker or emergency
switch is installed in the building installation.
Connection of DC Mains
Unless otherwise specified in the manual, the DC input to the equipment is floating in reference to the
ground. Any single pole can be externally grounded.
Due to the high current capability of DC mains systems, care should be taken when connecting the DC
supply to avoid short-circuits and fire hazards.
DC units should be installed in a restricted access area, i.e. an area where access is authorized only to
qualified service and maintenance personnel.
Make sure that the DC supply is electrically isolated from any AC source and that the installation
complies with the local codes.
The maximum permissible current capability of the branch distribution circuit that supplies power to
the product is 16A. The circuit breaker in the building installation should have high breaking capacity
and must operate at short-circuit current exceeding 35A.
Before connecting the DC supply wires, ensure that power is removed form the DC circuit. Locate the
circuit breaker of the panel board that services the equipment and switch it to the OFF position. When
connecting the DC supply wires, first connect the ground wire to the corresponding terminal, then the
positive pole and last the negative pole. Switch the circuit breaker back to the ON position.
A readily accessible disconnect device that is suitably rated and approved should be incorporated in
the building installation.

FXS (Foreign Exchange Subscriber) TNV-2 Telecommunication Network Voltage-2:
Ports whose normal operating voltage exceeds the
limits of SELV (usually up to 120 VDC or telephone
ringing voltages), on which overvoltages from
telecommunication networks are not possible. These
ports are not permitted to be directly connected to
external telephone and data lines.
FXO (Foreign Exchange Office), xDSL

ISDN
TNV-3 Telecommunication Network Voltage-3:
Ports whose normal operating voltage exceeds the
limits of SELV (usually up to 120 VDC or telephone
ringing voltages), on which overvoltages from
telecommunication networks are possible.
Always connect a given port to a port of the same safety status. If in doubt, seek the assistance of a
qualified safety engineer.
Always make sure that the equipment is grounded before connecting telecommunication cables. Do
not disconnect the ground connection before disconnecting all telecommunications cables.
Some SELV and non-SELV circuits use the same connectors. Use caution when connecting cables.
Extra caution should be exercised during thunderstorms.
When using shielded or coaxial cables, verify that there is a good ground connection at both ends. The
earthing 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.

Caution
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cords.
ttentio
Pour réduire les risques s’incendie, utiliser seulement des conducteurs de
télécommunications 26 AWG ou de section supérieure.
Some ports are suitable for connection to intra-building or non-exposed wiring or cabling only. In such
cases, a notice will be given in the installation instructions.
Do not attempt to tamper with any carrier-provided equipment or connection hardware.
Electromagnetic Compatibility (EMC)
The equipment is designed and approved to comply with the electromagnetic regulations of major
regulatory bodies. The following instructions may enhance the performance of the equipment and will
provide better protection against excessive emission and better immunity against disturbances.
A good earth connection is essential. When installing the equipment in a rack, make sure to remove all
traces of paint from the mounting points. Use suitable lock-washers and torque. If an external
grounding lug is provided, connect it to the earth bus using braided wire as short as possible.
The equipment is designed to comply with EMC requirements when connecting it with unshielded
twisted pair (UTP) cables. However, the use of shielded wires is always recommended, especially for
high-rate data. In some cases, when unshielded wires are used, ferrite cores should be installed on
certain cables. In such cases, special instructions are provided in the manual.
Disconnect all wires which are not in permanent use, such as cables used for one-time configuration.
The compliance of the equipment with the regulations for conducted emission on the data lines is
dependent on the cable quality. The emission is tested for UTP with 80 dB longitudinal conversion loss
(LCL).
Unless otherwise specified or described in the manual, TNV-1 and TNV-3 ports provide secondary
protection against surges on the data lines. Primary protectors should be provided in the building
installation.
The equipment is designed to provide adequate protection against electro-static discharge (ESD).
However, it is good working practice to use caution when connecting cables terminated with plastic
connectors (without a grounded metal hood, such as flat cables) to sensitive data lines. Before
connecting such cables, discharge yourself by touching earth ground or wear an ESD preventive wrist
strap.

Troubleshooting and
Diagnostics
4.1 Performing Local Analog Loopback
RIC-E1 supports activation of a V.54 diagnostic (loop 3) local loopback.
This loopback checks the communication and connection between RIC-E1 and the
attached DTE, as shown in Figure 4-1. When RIC-E1 performs a local loopback,
the data received from the local transmitter is both transmitted on the line and
looped back to the local receiver at the digital level. This checks the operation of
all local digital circuitry.
