Bogen UTI312 Dialing Time-out, DTMF Block, Timers, Calling Party Controlled Disconnect, VOX Timer

Dialing Time-out

Dialing Time-out can be enabled or disabled and by default is enabled.When enabled, the dialing time-out starts as soon as the unit becomes active. The dialing time-out lasts 15 seconds and is reset with every DTMF tone until the string is complete. If no DTMF is detected within those 15 seconds, there will be an error tone.This feature is only valid in RUN mode, not PROGRAM mode.When dialing time-out is disabled, the unit will follow the default timer.

DTMF Block

If enabled, DTMF Block suppresses DTMF keys so that only a short portion of the tone can be heard over the speakers during a page. Disabling DTMF Block allows a user to pass DTMF keys to external equipment connected to the zone outputs during a page.

Trunk Disconnect

The UTI312 includes a Trunk Disconnect feature. The purpose of the Trunk Disconnect feature is to release the UTI312 from the trunk port in the event a user does not hang up the phone properly after making a page. If the UTI312 does not detect voice for the interface VOX time-out period, or if the interface default timer expires, the UTI312 will attempt to release from the trunk by momentarily interrupting the talk battery.When using the Trunk Disconnect feature, the PBX must have disconnect supervision available on the trunk port being used. The Trunk Disconnect feature is disabled by default.

Timers

Default Timer

If the UTI312 is connected to a PBX station port, or a trunk port with the Trunk Disconnect feature enabled, you can set the maximum page duration (default timer). The factory setting for this timer is 30 seconds and can be adjusted in 10 second increments up to 990 seconds.This timer can be inhibited. See System Programming for more information on setting or inhibiting the Default Timer.

VOX Timer

If the UTI312 is connected to a station port, page port VOX, or trunk port with the Trunk Disconnect feature enabled, you can set the time duration for the maximum silence duration time-out.The factory setting is 6 seconds and can be adjusted in 1 second increments up to 9 seconds. This timer can be inhibited. See System Programming for more information on setting or inhibiting the VOX Timer.

Calling Party Controlled Disconnect

When in station mode, the UTI312 will immediately disconnect when it detects a CPC (calling party control) signal. A CPC signal is a loss of loop current for greater than 300mS. It is typically issued by the PBX or CO immediately after the calling party hangs up, but can be delayed for up to 10 seconds depending on the equipment issuing the signal.The UTI312's detection and disconnection is not defeatable and is the only way to disconnect from a station port if both the Default and VOX Timers are inhibited.

Setup Tone

This tone can be activated only when the system is in Program mode (set with Run/Program switch). It is an all-call interrupted tone that can be used by the installer to check speaker operation and to set the operational level of the speakers.

Note:The volume level of this tone is controlled by the Tone Level Control.

Reset Default Values

A feature code is available to reset the UTI312 system to the original factory default values.Wait for a confirmation tone before hanging up.This will not clear any flexible dialing numbers that have been programmed into the system.
