Federal Communications Commission
Radio Frequency Interference Statement
This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to Part 15 of the FCC Rules. This
device complies with Part 15 of the FCC rules. Operation is subject to
the following two conditions:
1. This device may not cause har mful interference,
2. This device must accept any interference received, including
interference that may cause undesired operation.
.
No changes or modifications to this unit are allowed
unless expressly approved by the pa rty responsible for
compliance. Modifications could void the user's authority
to operate the equipment within the FCC rules.
Canadian Emissions Requirements
This digital apparatus does not exceed the Class B limits for radio
noise emissions from digital apparatus, as set out in the interferencecausing equipment standard entitled “Digital Apparatus,” ICES-003
of the Department of Communications.
Cet appareil nuerique respecte les limites de bruits radioelectriques
applicables aux appareils numeriques de Class A prescrites dans la
norme sur le materiel brouilleur: “Appareils Numeriques,” NMB-003
edictee par le ministre des Communications.
iv
Canadian Equipment Limitations
Notice: The Canadian Industry and Science Canada label identifies certified equipment. This certification means that the equipment meets certain telecommunications network protective, operational, and safety
requirements. The Department does not guarantee the equipment will
operate to the user’s satisfaction.
Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications
company. The equipment must also be installed using an acceptable
method of connection. In some cases, the company’s inside wiring associated with a single line individual service may be extended by means
of a certified connector assembly (telephone extension cord). The customer should be aware that compliance with the above limitations may
not prevent degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian maintenance facility designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment
malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.
Users should ensure for their own protection that the
electrical ground connections of the power utility, telephone lines and internal metallic water pipe system, if
present, are connected together. This precaution may be
particularly important in rural areas.
Users should not attempt to make such connections
themselves, but should contact the appropriate electric
inspection authority, or an electrician, as needed.
The Load Number (LN) assigned to each terminal device denotes the
percentage of the total load to be connected to a telephone loop which
is used by the device, to prevent overloading. The termination on a loop
may consist of any combination of devices subject only to the requirement that the total of the Load Numbers of all devices does not exceed
100.
v
IMPORTANT SAFETY INSTRUCTIONS
When using telephone equipment, please follow these
basic safety precautions to reduce the risk of fire, electrical shock, or personal injury.
1. Do not use this product near water , such as a bathtub, wash bowl,
kitchen sink, laundry tub, in a wet basement, or a swimming
pool.
2. Avoid using a telephone (other than a cordless type) during an
electrical storm. There is a remote risk of shock from lightning.
3. Do not use the telephone to report a gas leak in the vicinity of the
leak.
4. Use only the power cord, power supply, and/or batteries indicated in the manual. Do not dispose of batteries in a fire. They
may explode. Check with local codes for special disposal instructions.

UNIT OVERVIEW
The ADTRAN T1 Channel Service Unit (CSU) Advanced Communications Equipment (ACE) provides the T1 interface between customer
premises equipment (CPE) such as channel banks, T1 multiplexers,
PBSs, etc., and the carrier network as shown in Figure 1-1. The unit
complies with Part 68 of FCC Rules and with applicable sections of
AT&T 62411, ANSI T1.102 and ANSI T1. 403.
The unit provides functions such as surge protection, signal regeneration, alarms, loopbacks necessary for circuit operation and fault isolation as illustrated in Figure 1-2 on page 1-2. The un it is transparent
to ESF or SF framing formats and AMI or B8ZS line coding.

POWER OPTIONS
The T1 CSU ACE may receive power from a local power supply located
on the customer’s premises. Local power can be supplied by the customer’s own 12 to 48-volt supply with the supplied power cable, or by the
wall-mount power supply shipped with the unit (see Figure 1-3). The
wall mount power supply is an NEC class 2 device.
See Powering the Unit on page 2-2 for details on
connecting the power to the unit.

POWERING THE UNIT
The T1 CSU ACE can be line powered if line power from the carrier is
available. If the T1 CSU ACE relay detects that local power is present,
the unit will ignore the line power. If line power is used, the power cable should be disconnected from the unit. The power is received f rom
the transmit and receive pairs of the network side of the T1 CSU ACE.
Local power may be tapped using the power cable supplied and the
customer’s own NEC class 2 48 volt power supply. A 48 volt @ 100 mA
wall mount power supply is shipped with the unit. See Figure 2-1 for
an illustration of cable installation. Once power has been applied to
the unit, the power led will be illuminated.
