at premises receptacle on the VIS-3. Connect
the other end of the cable to the phone
connection to the whole premises.

Digital Voice Service receptacle on the VIS-3.
Connect the other end to the RJ11 output from
the voice output of ONT (Optical Network

Testing
1. On power-up the unit is in Digital Voice Mode.
The LED should start flashing within a few
seconds of powering up (Figure 3).
2. The VIS-3 will automatically switch to DAS /
Intercom Mode when the Local Digital Voice
Service power is disconnected.
3. When the DAS / Intercom rings and the Digital
Voice line is on hook, the VIS-3 will switch to
the DAS / Intercom. After answering the
intercom or the ringing has stopped, the VIS-3
will switch back to Local Digital Voice Service
mode.
4. To answer the DAS / Intercom when the
Digital Voice line is in use, press the flash
hook switch momentarily, this will hold the
Digital Voice line and at the same time switch
the VIS-3 to DAS / Intercom mode.
5. When finished with the DAS / Intercom call,
press the flash hook switch momentarily to
recover the Voice line. In some case the flash
switch may need to be activated twice to
recover the voice line.
