The Model 9800 by Connect Systems, Inc. has the best features to cost ratio of any competing interconnect available today. The Model 9800 is the obvious choice for interfacing any simplex or duplex radio system to the Public Switched Telephone Network!

Vox mode provides the mobile with clear audio (free of sampling interruptions) just like you would hear on your office phone.

In sampling mode, the base station periodically switches into receive for a moment to see if the mobile is transmitting. This gives the mobile the ability to break-in and have immediate full control.

In this duplex mode, the mobile can press the mike button and talk at any time, which immediately cutts off the land side audio.

The model 9800 provides everything necessary to convert any receiver and transmitter into a high performance repeater with built in duplex phone patch.
