and still have all of those devices ring when your telephone number is called. In most, but not all
areas, the sum of the REN's of all devices connected to one line should not exceed five (5.0). To
be certain of the number of devices you may connect to your line, as determined by the REN,
you should contact your local telephone company to determine the maximum REN for your
calling area.
Direct Connection to a Party-Line or Coin Operated Telephone Line is Prohibited.
Incidence of Harm to the Telephone Lines
Should terminal equipment cause harm to the Telephone Network, the Telephone Company shall, where practical,
notify the customer that service may be temporarily discontinued. However, where prior notice is not practical, the
Telephone Company may temporarily discontinue service, if such action is reasonable in the circumstances. In
case of such un-notified temporary discontinuance of service, the Telephone Company shall:
(a) Promptly notify the customer of such temporary discontinuance of service.
(b) Afford the customer the opportunity to correct the situation which gave rise to the temporary
discontinuance.
(c) Inform the customer of the right to bring a complaint to the FCC pursuant to the procedures set
out in Subpart E of Part 68 of FCC Telephone Equipment Rules.

Compatibility of the Telephone Network and Terminal Equipment.
(a) Availabilityof telephone interface information.
Technical information concerning interface parameters and specifications not specified in FCC
Rules, including the number of Ringers which may be connected to a particular line, which is
needed to permit Terminal Equipment to operate in a manner compatible with Telephone
Company communications facilities shall be provided by the Telephone Company upon
customer's request.
(b) Changes in Telephone Company Communications Facilities, Equipment, Operations and
Procedures.
The Telephone Company may make changes in its communications facilities, equipment, operations or procedures
where such action is reasonably required in the operation of its business and is not inconsistent with the rules and
regulations in FCC Part 68 of the FCC Rules and Regulations. If such changes can be reasonably expected to
render any customer Terminal Equipment incompatible with Telephone Company Communications Facilities, or
require modification or alteration of such Terminal Equipment, or otherwise materially affect its use or performance,
the customer shall be given adequate notice in writing to allow the customer an opportunityto maintain
uninterrupted service.

Includes all versions through G1-a20x
Description
The TD-824i is an advanced digital telephone system employing a microprocessor stored program and digitally
controlled solid state time-division switching. The TD-824i system is specifically designed for small business as well
as residential applications. At the forefront of the system’s design is a universal concept to adapting and connecting
with a variety of communications devices. Productive TransTel Digital Key Telephones offer thoughtfully designed
feature access to keep you connected with one another and with customers. TransTel technology leads the
industry in providing for compatibilitywith devices such as fax machines, answering machines, cordless phones,
computer modems and other office/home equipment.
Key highlights of the TD-824i includes:
Economy and Efficiency
The base system is equipped to support four (4) CO lines and eight (8) digital stations. The system may be
expanded to a maximum of eight (8) CO lines / or four (4) CO lines and three (3) ISDN Basic Rate Interfaces.
Station cards may be selected to allow practically any combination ranging from all TransTel Digital Key Sets to all
industry standard Single Line Telephone sets, with almost any combination of the two types. In addition to being cost
effective at the initial phase and for expanding to it's maximum capacity, the TD-824i system also is economical to
operate, as it consumes about the same amount of electricity at full configuration as a 60 watt light bulb. A
maximum of 8 CO lines (or 3 ISDN BRIs) and 24 Extensions can be accommodated. This allows a wide variety of
applications for the system to work effectively
Easy Installation
•“Factory Ready” - All TD-824i Telephone systems are "ready to go" right out of the box. A default database is
factory installed on each system, which meets the needs for most installations. In most cases, this alleviates
hours of on site time, reducing installation costs for both dealer and customer.
•“Small & Compact” - The Key Service Unit's small size takes little space for installation and is about the size of
a piece of legal paper.

TransTel Model TD-824-I Digital Telephone System – General Description
Page 13
Easy Maintenance
•Solid-state design minimizes trouble and eliminates periodic maintenance.
•EasyExpansion. Various Interface Cards for simple, modular expansion.
•Versatile programming and options for ease of selection.
•Database Battery Back Up - Customer data is backed up when the power is turned off and back on. Batteries
can periodically be replaced with power on using commercially available replacements.
•Battery Back Up (System Operation) - TD-824i systems can be equipped with an optional battery back up
which keeps the system operational for up to 4 hours in the case of a commercial power failure.
•Customer Care Programming - Customers and service personnel can easily communicate and perform
programming right over the telephone. TransTel telephone systems allow programming and voice
conversations to co-exist at the same time.
•Advanced software upgrades – Through the RS232 connection, system software can be upgraded easily
without firmware “chip” replacements.
Flexibility of System Applications
Unlike other conventional systems in the TD-824i size range, the installer will find an unprecedented range of
customer database programmability. In "system parameters" there are extensive options for various timing settings
related to features. An array of parameters is programmable for signaling options on outside lines and internal
single line telephone sets. The installer may Enable/Disable many system wide features. And in class of service,
there are over 20 options for each station providing maximum flexibility for nearly any application.
Varied Extension Alternatives
You can connect Transtel DK series Key telephones, TransTel Access Control Phones (ACP), Digital Door Phones
and conventional industry standard single line sets, Modems, Answering Machines, Cordless phones, etc. directly to
the KSU. This feature provides you with the choice to select different extension equipment to suit individual
applications.
Digital Twin Port
Install two Digital Key telephones on a single two-wire cable. No Master and Slave difference. Any key telephone
can be plugged in and unplugged with no interference to the other. This feature allows easy cabling, easy
expansion and easy maintenance.
Liquid Crystal Display
The TD-824i Series Model DK-1/D and TransTel’s DK-3D telephones are equipped with a large, easy to read LCD
display. The LCD is 32 characters total, comprised of 2 rows by 16 characters each. This LCD provides an
invaluable tool for simplifying the use of the telephone by identifying the calling extension by name, outside lines by
name and self prompting displays for feature access. Station feature usage is made simple with the help of the
LCD display. Continuous prompting information is displayed during calls so that users know what to do and when to
do it.
32-character LCD Display shows:
•Time •Last number dialed
•Dialed telephone number •The status of operation/function
•Voice Mail Messages •Absent messages
•CO Line Names •Speed Dial Directory
•Last Number Redial •Calling Party Name
•Speed dial number •Input data during system data entry
