DTS821 in Brief

DTS821 is an executive digital telephone set for “Telesis PX24 Hybrid IP PBX
Business Phone Systems” and “Telesis X1 Switching Systems” for the comfort of the
user. DTS821 has easy-to-use quick-access keys, menu keys and numerous dedicated
keys for various telephony tasks and personnel settings. It has a large back-lighted
graphic LCD.

DTS821 is connected and powered by a single pair of wires, which is connected to the
digital subscriber ports of a Telesis PBX system. The DTS821 handles multiple calls
simultaneously, such as receiving a new call while keeping another on hold.

Intelligent algorithms within the operating system of the Telesis PBX or switching
systems make the firmware upgrade of DTS821 digital sets automatic whenever new
features are added in time. Furthermore, since all the user parameters are stored in
Telesis PBX or switching system, replacing and/or upgrading a DTS821 digital set
does not require any re-programming.
