Warr anty Warnings
!
Modifying or tampering with PSAX chassis components may void your
warranty. Any modification to this equipment not expressly authorized
by Lucent Technologies may void your granted authority to operate such
equipment.
!
When inserting modules into the chassis, slide them gently, not
forcefully. Excessive force may cause the modules to be seated
improperly in the chassis, and result in possible damage to the module or
the chassis. Install or remove modules one at a time. Doing this aids in
preventing the Multiservice Media Gateway system from indicating any
erroneous failure messages, and allows the Multiservice Media Gateway
system to reinitialize and display the accurate configuration of the
module that is inserted.
!
Shipping the chassis with removable modules installed may cause
damage to the chassis and the modules. Damage to any of the
components in the system resulting from shipping the chassis with
removable modules installed could void your warranty. Only Lucentauthorized personnel should ship the Multiservice Media Gateway
chassis with a module installed.

Electrostatic Discharge Precautions
Electrostatic Discharge Precautions
The room where the Multiservice Media Gateway system is located must
have built-in precautions to provide protection from electrostatic discharge
damage to electronic components. The following sections provide details on
these necessary precautions.
Grounding Wrist Straps
Attach at least one grounding wrist strap to a common ground for each
chassis/electronic rack to be handled. Follow these guidelines for wrist straps:
•Make sure the wrist straps or wrist strap cords have built-in 1-megaohm
(minimum) resistance.
•Make sure the wrist straps and wrist strap cords are UL listed.
•Ensure the wrist strap cord is long enough so it can be worn while
working either at the front or the back of the rack.
•Always discharge any static charge by touching your wrist strap before
you touch the Multiservice Media Gateway chassis.
Floor Covering
Be sure the room has an antistatic floor covering (conductive mat, tiles, or
carpeting) to minimize static charge buildup as you walk across the room.
Follow these guidelines for installing and maintaining proper floor coverings:
•Using foot grounding straps (attached to the heels of your shoes) is
recommended, even if you are walking in rooms with antistatic floor
covering. These straps provide additional protection against electrostatic
discharge. The straps should have built-in 1-megaohm (minimum)
resistance.
•Wool carpet is not an acceptable floor covering.
•Other types of carpet must be sprayed daily with a topical antistatic
chemical before you perform any work in the room. Paying constant
attention to carpet maintenance is time-consuming but required, if used.
Temperature and Humidity
Establishing the proper temperature and humidity in the room where the
Multiservice Media Gateway system is located helps control many static
discharge problems. Maintaining proper room climate is especially important
when heat is turned on during the cold weather. To avoid damage to the
Multiservice Media Gateway system, do not allow the humidity to increase to
the level where water droplets appear on surfaces.
When working with the Multiservice Media Gateway system, avoid wearing
clothing made from wool or synthetic materials. Try to minimize contact
between clothing and electronic components.
Handling Multiservice Media Gateway System Components
Follow these guidelines for proper handling of the Multiservice Media
Gateway hardware to minimize electrostatic discharge damage:
•Do not remove the chassis, modules, and other items from their
protective packaging until you are ready to install them.
•When installing modules and components, use a grounding wrist strap
connected to a common electrical ground to prevent electrostatic
discharge damage. (A common electrical ground is a complete circuit
between a person or an electrical/electronic device and the earth.)
•Store components in electrostatic-discharge-protective bags when they
are not in use.

The Voice 4-Port 2-Wire Office module provides support for the office
(central office or PABX switch) end of a two-wire analog telephone line. This
allows a voice loop from a voice switch to be connected directly to a
Multiservice Media Gateway system and communicate over an ATM network
to a distant telephone or other analog device.
The 4-Port Voice 2-W ire Office module has three types of LED indicators:
ACTIVE, FAIL, and LOS (loss of signal). Each port has a LOS LED on the
faceplate. The LED turns on when the port goes off-hook. It also turns on and
off in synchonization with an incoming ringing signal to the port.

CAUTION:
When using a DSP2A, DSP2B, DSP2C, or DSP2D Voice Server module and
an Enhanced DS1 or E1 module with a PBX and/or key telephone system,
the Multiservice Media Gateway system and your equipment should use
a common chassis ground connection to avoid ground current loops,
which could affect voice quality.
