Introduction
This section describes the ATLAS EX 60 Digital Business System, a small telecommunications
system that provides voice communications with a wide range of features. An overview of the system
equipment is presented: followed by instructions for installing the system and station equipment and
for connecting optional devices supported by the system. System specifications are grouped for a
quick reference guide.
This equipment can be used with telephone company equipment that accepts pulse or DTMF dialing.
The equipment has been assigned an FCC registration number under Part 68.
For direct connection to the telephone network, the equipment must be installed as described, and the
FCC registration must be reported to the local telephone company.
FCC Requirements
The ATLAS EX 60 Digital Communication System is FCC-registered as a fully protected key system
under Registration Number – PENDING, Ringer Equivalence 0.2a
Related Documents
For additional information regarding station feature operation, refer to the Easy reference guide
included with each Digital set.
For details related to changing system database, refer to ATLAS Series 500 Programming guide.
Note:
To maximize user satisfaction and to minimize service calls, it is strongly recommended that all users
be instructed in station operation and that every station user be provided with a copy of the Easy
Reference Guide.
Incidence of Harm
When practical, the telephone company must inform the customer that the service may be
temporarily discontinued if the equipment he is using should cause harm to the telephone network.
The telephone company must attempt to inform the customer that the service is to be discontinued
prior to actually terminating service. The telephone company must also provide customers with
opportunity to correct the problem and must advise customers of their right to bring compliant
procedures before the FCC.

General Description
This part provides an overview of the system equipment, including descriptions of cabinet, cards, and
station instruments.
Note: The system’s programmed database is changed using Three Programming Sections with 99
two-digit MODE numbers per section. Each MODE number represents a changeable feature or
function parameter. The Section and Mode numbers are referenced throughout the descriptions in this
document (e.g. PROG.1-37 = Section 1, Mode 37) to allow quick access to programming information
when required for clarity. Instructions for using Mode numbers to change the database are contained
in the Series 500 Programming Guide.
System Summary
The ATLAS EX 60 is a Digital Communication system that operates like a Key System or as a
multifunctional PABX, depending on database programming. System operation is controlled by a 16-
bit 8830 microprocessor. Digital switching uses CMOS technology to assure non-blocking operation.
The 8830 microprocessor performs all logical operations and passes control signals to other circuits
in accordance with system demands. Microprocessors located in each Digital Phone in the system
communicate with the system controller for operational control.
System and station feature operations and selected system functions are controlled by a stored
program database. The database in default state is stored in on-board EPROM. The default database
is copied to battery-protected RAM during system initialization. It supports a fully operational
system. Values in the RAM-based data can be changed as needed.
The system can be configured 52 ports with 16 Trunks, 24 Digital stations and 4 Single-Line
telephones. Regardless of capacity used the system remains non-blocking with consistent voice
quality.
The system supports ATLAS 1-pair Digital keyphones and industry-standard single-line phones
(with electronic ringers). One Digital Display phone is required for system programming. 64 Button
Digital DSS consoles can be equipped to operate as a companion to Digital keyphones. Each console
occupies one digital port.
The ATLAS Digital keyphones are available in LD40 (6-line by 20-character Display) and DT 36
/ DB type button models. The DT 36 / DB type button is available with a 2-line by 16-character
Display. All ATLAS Digital keyphones are headset compatible.
Equipment Summary
ATLAS EX 60 Installation - 5 -
The Main equipment cabinet is modular in design. It houses the power supply and the MBU Unit.
The power supply occupies the bottom portion of the cabinet; the MBU card occupies the remainder
of the cabinet. The MBU Unit controls system operation, 4 Trunks, 8 Digital ports and 4 single-line
ports. An Expansion card can be added which supports an additional 2 BRI, 4 TKU, 8 DSU and 8
SLU.
The power supply is a wired–in unit. The outputs are +5 Volts at 3amps, -28 Volts at 4amps and –60
Volts 1amp. Full control is available for a customer-supplied backup battery, including trickle-charge
capabilities.
Note: SLP ring voltage is 45VAC (rms) and will not support Mechanical type ringers.
Trunk interface circuits support Loop-start trunk applications. Trunk lines connect to the MBU card
through card-edge-mounted modular jacks.
Digital keyphones and Single-line telephones connect to the MBU through a card-edge-mounted RJ-
11 or Quick.
Options available and supported by the system include:
1-programmable external music source interfaces
1-external page port interface
2-programmable external relay interfaces
2-serial port interfaces
1-connecting terminals and control circuit for backup batteries
Numbering Scheme
Station and Trunk Port numbers are fixed and cannot be changed. Station extension numbers are
assigned in the default database but can be changed by system programming (PROG.2-70). Default
station numbers are 10 – 45. One, two, three or four digit station numbers can be programmed. The
system does not allow conflicts in station number assignments (i.e. station number 20 and station
number 200), but does allow the same number to be assigned to more that one port, when this occurs
only the lowest numbered port can be called on intercom.
Dial access codes are used at keyphones and single-line phones to access features. At keyphones, all
features can be accessed by fixed feature buttons, programmable softkeys, or by dial access codes.
The feature access codes are listed in Table A.
