Hubbell Electric Heater Company TI984 Operating Instructions, Answering Incoming Calls

MODEL TI984 TELEPHONE INTERFACE	42004-071F

If someone calls and discovers that the designated party line is busy, they can choose the voice access method to notify the person they are trying to reach to return their call. The selective access method ensures that, even when the designated party line is in use, incoming calls are not shut out.

Using this method, the incoming call is automatically answered by the telephone interface. The telephone interface generates an audible signal that is heard by the calling party. The signal indicates the status of the party line: one beep indicates that the party line is not in use and three beeps indicates that the party line is in use.

The telephone caller has 30 seconds to respond by dialing one of two 2-digit codes:

The first code, 1X, accesses the page line as done in the Voice Access method; and the second, the 1Y code, rings on the page line as done in the Ring Access method. The programmer can chose any numbers from 0 to 9 for X and Y, but note that X and Y must be different. Refer to the Programming Table on page 11 for additional information.

Four programmable parameters are available with the Selective Access method.

Programmable Parameters

∙Page duration (0 to 99 seconds) -- the amount of time the caller has to make a page before being automatically connected to the party line

∙The maximum number of seconds the call will be held before it is disconnected if not answered (0 to 99 seconds)

∙Enabling or disabling the auto-connect mode. If the unit is programmed to auto-connect, the caller will be directly connected to the designated party line if that line is already off-hook

∙Access codes – the two-digit code used by the caller to access either the page line or the party line

Manual Access Method

The manual access method is ideal for use when the TI984 is connected to a switchboard manned by an operator. All incoming calls go to the switchboard, and the operator must connect the call by pressing the ACCESS button on the front cover of the TI984. The TI984 is inactive until the operator presses the ACCESS button.

Operating Instructions

Many of the operating details of the TI984 are explained in the Programming Procedure section (page 7), and the operation of the TI984 is often dependent on the selected parameters. For instance, when using the selective access method for incoming calls, the directions on accessing the Page/Party® line are different than when using the voice access method. However, some operations remain the same regardless of the programmed parameters. The details of these particular parameters are outlined below.

Answering Incoming Calls

Incoming calls can be answered in the following ways:

∙If the designated party line is idle (with all stations on the designated party line on-hook), the call is answered when any station on the designated party line goes off-hook. If the party line is in use, all the stations on the party line must be on-hook before the call can be answered.

∙With the voice access method selected, the TI984 can be programmed to automatically connect to the designated party line, even if the party line is in use. The call is connected after a programmed number of rings and a preset paging period has elapsed.
