The Hytel Digital Key system is a hybrid key-system that delivers remarkable
performance for an equally remarkable price. It offers numerous advanced
user features and system features you'd expect to find only on high-priced large
business systems. Hytel's unique LCD window (LCD keyset only) combined with
three interactive function keys prompts you on common system commands, making
Hytel systems extremely user-friendly.

All Hytel systems are designed for maximum flexibility and can be easily expanded.
Background music, music-on-hold, paging, caller identification, battery backup,
automated attendants/voicemail, door stations and many other auxiliary items can
be connected to any Hytel system.

Digital 2+D technology is used for extension cabling, giving Off-hook Voice Announce
and Alert Calling facilities to 20-key display telephones. Your technician uses a
PC-based program for major system changes. The end-user system attendant can
program minor system features such as user names and alter the system time by
using keyset programming from any display telephone connected to the system.
Detailed step-by-step user guides covering system operation and features are supplied
with each Hytel system.
