Telephone System Connections

The UTI312 connects to virtually any telephone system: PBX station lines and CO lines, PBX loop start trunk ports, PBX ground start trunk ports, and page ports.

Interface installation consists of setting the slide switches and connecting with modular (RJ11) telephone plugs. Refer to the appropriate procedure in this section to connect the UTI312 to the telephone system.

Note: In all cases, make sure that power to the UTI312 is disconnected before performing the installation.

PBX Analog Station Port

In this configuration, the unit answers immediately upon detecting a ring. As soon as it answers, the default timer andVOX timer are started.The default timer determines the maximum length of any page.TheVOX timer repeatedly resets as long as audio is detected on the line. If no audio is detected within the VOX time period, then the page will end. If audio continues to be detected, then the default timer will control page length.

The unit will also immediately disconnect if a loss of loop current CPC (Calling Party Disconnect) is detected.

Make sure that the power is off and all connections are completed before proceeding. Move the interface slide switch on the UTI312 to STATION. The other interface slide switch is not used and can be in any position. Use a modular telephone cord (minimum 2-conductor) to connect the UTI312 Station Port RJ11 to the phone system. The center two conductors are Tip and Ring and are not polarity sensitive (see below). Set Default and VOX timers (see System Programming).The timers can be independently inhibited.

Note:The default time-out is factory set to 30 seconds, and the VOX time-out is set to 6 seconds. If both the default and VOX timers are inhibited, the only way to release the system from the station line is through the use of a Calling Party Control (CPC) pulse.
