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
