6.1.4 Operation: Cross Connecting a STU-III phone
1) Once the STU-III has gone secure the user may cross connect it to another STU-III
phone, a local phone, radio, sound card in computer, or any other audio device. To
cross connect, the user would connect the DSP-2 module being used to the other
extension he/she wants to connect with. The process may be done via the ACU
Controller software program or the HSP-2A module. The procedure for cross
connecting is defined in Section 3.2 and Section 3.5.1.1.
a) EXAMPLE: To connect extension one with extension eight via the control
console, the user will click on the Connect ICON on the top of the screen. The user will
put the cursor on DSP-2 number one and click the left button and then on DSP-2
number eight and click on the left button. The screen will show the two connected
together.
b) To disconnect the two extensions, the user should left mouse click the
disconnect icon located on the top of the screen. The user will place the
cursor on one of the extensions connected together and click on the DSP-
2 icon. This will disconnect the two DSP-2 modules and the cross
connection will be broken.
