## Analogue Telephone

## Definition

Analogue telephone denotes the connection of a standard telephone with rotary dial or Dual Tone Multi Frequency (DTMF) signalling.
The concept also embraces other equipment that from a signalling point of view functions like an analogue telephone.

## Use

Analogue connection can be significant for the connection of special units such as:

- Telephone answering machine
- Telefax
- Modem
- Entryphone
- Telephones for special environments

## Operation

See under relevant facility description.

## Capacity

The number of analogue connections is limited by the number of connected ELU-A boards and the maximum extension capacity (200, for hotel configurations the limit is 300).

Each ELU-A board offers 16 connection options.

Each ELU-A board has four DTMF-receivers and one ring generator.

## Limitations

In certain cases units such as modems and telephone answering machines require ring signals of a certain duration. Such extension positions can be programmed so that only a single ring signal is provided, irrespective of whether the call is external or internal.

For analogue extensions it is not possible to enable ringing for all individuals on the same board at the same time. An analogue extension board (ELU-A) can provide the ringing voltage only for one instrument at the same time. The request for all other instruments will be queued. In that case the ringing signal will be multiplexed over the queued instruments. The repetition rate of the ringing signal will go down depending on the number of parallel ringing instruments located on the same board.

## Programming

0122 |  | Long ring bursts ?

0124 |  | Call waiting tone for analogue extensions ?

The following commands are only accessable via BMS/RASC:

0143 |  | Line break for ELU-A

2007 |  | Rotary dial type

2105 |  | Minimum release signal

2106 |  | Minimum register signal
