Test Phone - Technician LCD

For PABX technicians, internal systems, and telephone exchanges, you can't go past the CZ20025.

A buttset its the basic tool of the trade for anyone working on phone lines and is an essential tool to have in your toolbox.

The Aegis range of test telephones are designed for use on all PSTN systems by line installers, repair technicians, and other tradespeople for phone line testing and monitoring.  There is a model suitable for every application, from basic to advanced, meaning you can choose the butt set that is right for you.

The CZ20025 is packed with the features needed for PABX and internal phone systems. The LCD provides features such as Caller ID, Digit Grabbing, PABX pause, and voltage/current display. The buttinski is ADSL compatible, featuring both data lockout and override to prevent disruption of an ADSL service, and the ADSL/POTS filtering allows you to go off-hook on an ADSL line. The one way speaker allows hands free monitoring and the memory provides storage for commonly dialled numbers.
