RTU-292 Operations Manual

7.3 LOCAL PHONE OPTION

The RTU-292 has an extra rear panel modular phone jack that allows a standard DTMF telephone set to be plugged directly into the unit when the Local Phone Option is installed. This Local Phone set can make and receive calls via the outside line, communicate with an operator at the RTU-292, or send and receive audio through the companion radio. It can also be used to program the RTU-292. The Local Phone Option consists of a small Printed Circuit Board assembly that is installed in the RTU-292 options tray. Theory of Operation information is included in section 4.

7.3.1 LOCAL PHONE OPTION INSTALLATION AND CONFIGURATION

The Local Phone Option is a small PCB that is installed to four threaded standoffs in the options tray, with a ribbon cable assembly that runs from the option to connector J20 on the Main Board. Figure 7.2 shows correct option placement in the options tray. The telephone set and interconnect cable to the telephone set are not included with the option.

After the Local Phone Option is installed, the main CPU must be informed by switching on the Local Phone Enable dipswitch, SW1-7, on the Main Board. Remember that these switches are only read at unit power-up. SW1-7 must be left off when the option is not installed. SW1-8 enables the Local Phone Ring-Through feature. This causes the local phone to ring whenever a call is received by the RTU-292 via the PSTN input. When ring-through is disabled, the local phone may still be used to send and receive calls, but will not ring when a call is received. Set SW1-8 to On to enable Local Phone Ring-Through, and Off to disable this feature. This switch should always be set to Off (disabled) when the Local Phone Option is not installed.
