RADIO FREQUENCY INTERFERENCE STATEMENT
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 frequencies. 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.
Shielded cables must be used with this unit to ensure compliance with Class A FCC limits.
Change or modifications to this unit not expressly approved by the
party responsible for compliance could void the user's authority to
operate the equipment.
CANADIAN EMISSIONS REQUIREMENTS
This digital apparatus does not exceed the Class A limits for radio noise emissions
from digital apparatus as set out in the interference-causing 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.
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
conditions 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.
Caution: Users should not attempt to make such connections themselves, but
should contact the appropriate electric inspection authority, or an electrician, as
appropriate.
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.

GENERAL DESCRIPTION
The ADTRAN DSU 5600 is a technologically advanced, high
performance Data Service/Channel Service Unit (DSU/CSU)
that provides the interface between telco provided Digital Data
Service (DDS) and the customer’s Data Terminal Equipment
(DTE).
The DSU 5600 supports both 56 kbps and 64 kbps loop service
rates and provides either synchronous or asynchronous modes
of operation for the DTE interface. When the DTE interface is
configured for synchronous operation, the DSU 5600 matches
the selected loop rate. When the DTE interface is configured for
asynchronous operation, it supports asynchronous data communications over either a 56 kbps or 64 kbps DDS service. In
asynchronous mode, the DTE can be configured to operate at
any of the standard asynchronous communication rates from 1.2
kbps to 57.6 kbps. All setup or configuration is accomplished
with a single eight position DIP switch that is accessible from
the back panel of the unit.

Select and Test Buttons
The front panel also contains two push-button switches for
selecting and controlling the various test modes for the DSU
5600.
Select Each time this switch is pressed the current test
mode is displayed by turning On one or more LEDs
to indicate the specific test.
Test Once the desired test mode is displayed on the test
status indicators, the test is initiated by activating
this switch. This switch is also activated to terminate any test in progress.

DSU 5600 Front Panel
A drawing of the rear panel of the DSU 5600 is shown in Figure
1-2. The 25-pin connector labeled PRIMARY EIA-232 provides
the synchronous/asynchronous DTE interface. Connection to the
DDS network is made using the 8-pin modular jack (RJ-48S)
labeled TELCO. The pin assignments for these connectors are
listed in the sections Network Connections and DTE Connections.
All setup or configuration parameters for the DSU 5600 are
selected with an eight position DIP switch that is accessible from
the rear panel. This switch is labeled OPTIONS, and reference is
made to the options chart on the bottom of the unit. The individual options are explained in detail in the section Powering.
A power cord is also shown on the rear panel of the DSU 5600.
The captive power cord on the back panel provides connection
to the AC/DC power supply.
