## Intercom

## Definition

An Intercom line is a bothway hot-line possibility between two extensions in the system.

## Use

The function is particularly useful for executive/secretary connections or between persons who call one another frequently.

The function can also be utilised between a VIP-extension and OPERATOR to identify calls with priority.

The function also allows the caller to be identified in a busy situation.

If so required, the line can be programmed for immediate answer. The call will then, provided there is no ongoing call on the telephone, be presented direct in the handsfree mode.

## Operation

### Digital Telephones

#### Outgoing calls

A call is initiated by:

1. Pressing intercom key for relevant extension.

- Lamp flashes to confirm connection.
- Ring control tone is heard.

#### Incoming calls

A call is indicated by:

1. Internal ring signal.

- If called party is busy on another traffic function only one muted ring burst will be received.
- Lamp for intercom line lights and flashes rapidly.

Calls via the intercom line are not indicated on the display before answer.

#### Answer

The call is answered by:

1. Pressing intercom line key.

- Lamp changes to connection flash.
- Ringing ceases.

#### Immediate answer

Only available on ECONOMYplus-, STANDARD- and EXECUTIVE Telephone.

If the intercom line has been programmed for immediate answer at the called extension, the call will be presented in the handsfree mode.

Both caller and called party hear a short tone whereafter speech connection is established.

#### Parking

A call on a intercom line can be parked individually by:

1. Pressing key or another traffic function key.

- Lamp flashes slowly.

The display on the telephone of parked party shows "PARKED".

The parked intercom line is reaccessed by a further depression of the key.
