Electromagnetic Interference Information
This equipment has been tested and found to comply with the limits for a 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. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference, in which case the
user will be required to correct the interference at his own expense.
Canadian Department of Communications (DOC)
Interference Information
This digital apparatus does not exceed the Class A limits for radio noise emissions set
out in the radio interference regulations of the Canadian Department of Communications.
Le Présent Appareil Numérique n’émet pas de bruits radioélectriques dépassant les
limites applicable aux appareils numériques de la class A prescrites dans le Règlement
sur le brouillage radioélectrique édicté par le ministère des Communications du Canada.

Use only AT&T-manufactured MERLIN LEGEND™ Communications
System circuit modules, carrier assemblies, and power units in the
MERLIN LEGEND Communications System (511A) control unit.
Use only AT&T-recommended/approved MERLIN LEGEND
Communications System accessories.
If equipment connected to the analog station modules (008, 408,
408 GS/LS) or to the MLX telephone modules (008 MLX, 408 GS/LS-
MLX) is to be used for in-range out-of-building (IROB) applications,
IROB protectors are required.
Do not install this product near water, for example, in a wet basement
location.
Do not overload wall outlets, as this can result in the risk of fire or
electrical shock.
The MERLIN LEGEND Communications System is equipped with a
three-wire grounding-type plug with a third (grounding) pin. This plug
will fit only into a grounding-type power outlet. This is a safety feature.
If you are unable to insert the plug into the outlet, contact an electrician
to replace the obsolete outlet. Do not defeat the safety purpose of the
grounding plug.
The MERLIN LEGEND Communications System requires a
supplementary ground.
Do not attach the power supply cord to building surfaces. Do not allow
anything to rest on the power cord. Do not locate this product where
the cord will be abused by persons walking on it.
Slots and openings in the module housings are provided for ventilation.
To protect this equipment from overheating, do not block these
openings.
Never push objects of any kind into this product through module
openings or expansion slots, as they may touch dangerous voltage
points or short out parts, which could result in a risk of fire or electrical
shock. Never spill liquid of any kind on this product.
Unplug the product from the wall outlet before cleaning. Use a damp
cloth for cleaning. Do not use cleaners or aerosol cleaners.

FCC Notification and Repair Information
This equipment is registered with the FCC in accordance with Part 68 of its rules. In
compliance with those rules, you are advised of the following:
■ Means of Connection. Connection of this equipment to the telephone network
shall be through a standard network interface jack: USOC RJ11C, RJ14C,
RJ21X. Connection to E&M tie trunks requires a USOC RJ2GX. Connection to
off-premises stations requires a USOC RJ11C or RJ14C. Connection to 1.544-
Mbps digital facilities must be through a USOC RJ48C or RJ48X. Connection
to DID requires a USOC RJ11C, RJ14C, or RJ21X. These USOCs must be
ordered from your telephone company.
This equipment may not be used with party lines or coin telephone lines.
■ Notification to the Telephone Companies. Before connecting this
equipment, you or your equipment supplier must notify your local telephone
company’s business office of the following:
— The telephone number(s) you will be using with this equipment.
— The appropriate registration number and ringer equivalence number
(REN), which can be found on the back or bottom of the control unit,
as follows:
If this equipment is to be used as Key System, report the number
AS593M-72914-KF-E.
If the system provides both manual and automatic selection of
incoming/outgoing access to the network, report the number
AS593M-72682-MF-E.
If there are no directly terminated trunks, or if the only directly
terminated facilities are personal lines, report the number
AS5USA-65646-PF-E.
The REN for all three systems is 1.5A.
— For tie line connection, the facility interface code (FIC) is TL31M and
the service order code (SOC) is 9.0F.
— For connection to off-premises stations, the FIC is OL13C and the SOC
is 9.0F.
— For equipment to be connected to 1.544-Mbps digital service, the FIC
is 04DU9-B for D4 framing format or 04DU9-C for extended framing
format, and the SOC is 6.0P.
— For equipment to be connected to DID facilities, the FIC is 02RV2-T
and the SOC is AS.2.
— The quantities and USOC numbers of the jacks required.
— For each jack, the sequence in which lines are to be connected: the
line types, the FIC, and the REN by position when applicable.
You must also notify your local telephone company if and when this equipment
is permanently disconnected from the line(s).
The REN is used to determine the number of devices that may be connected to
the telephone line. Excessive RENs on the line may result in the devices not
