## Paging

## Definition

Paging denotes a function where, by connecting different types of external equipment, personnel in a certain area can be located.

Paging in ASB 150 02 can be one of the following types:

- Radio paging via bleeper
- Radio paging via display receiver
- Acoustic paging.

- See Loudspeaker Paging (322/155 34-ASB 150 02 Uen).

## Use

Equipment for paging is essential for activities where people (employees) are mobile when carrying out their duties and must be accessible.

Those who are to be paged (pagees) are equipped with a pocket receiver that can be one of two kinds:

- Bleeper with/without speech possibility
- Display pager with/without speech possibility

### Bleeper

A bleeper signals with sound only.

To ascertain who the pager is, the pagee must answer the call with an answer code.

“Meet-me paging” means that the pager waits with handset off-hook and the pagee replies with a special answer code (meet-me answer).

### Paging unit with display

Also a paging unit with display issues a sound signal, but here there is also a display that shows the pager's extension number.

Display paging enables an internal pager to replace her/his handset immediately.

The pagee then uses the nearest (any) telephone to dial the number shown on the display.

### Connection of external paging equipment

The radio signals to the receivers are transmitted from a base station that is connected to ASB 150 02.

Connection is set up via a selected analogue trunk.

Signalling to the paging equipment utilises loop signalling.

## Operation

### All telephones

#### Start standard paging

Paging can be activated both from idle state and during an ongoing call.

#### Call from idle state

Pager dials selected call number for paging.

Pager dials directory number of extension to be paged.

##### Pagee has display receiver

Pager hears verification tone when paging message has been sent.

Pager can now replace handset.

##### Pagee has bleeper

Pager hears ring control tone until pagee answers.

#### Activation of paging on no reply

On no reply, pager dials relevant postdialling digit (normally 7) in order to activate paging.

##### From analogue telephone

1. Press R-button and 7.

- Ongoing call is disconnected whereafter call to paging equipment takes place.
- If pagee has display receiver, pager will hear verification tone when paging message has been sent.

1. Pager can now replace handset.

- If pager has bleeper, pager hears ring control tone until pagee answers.

#### Answer

The answering procedure varies, dependent on the type of paging receiver

##### Display receiver

For internal paging the following applies:

1. Pagee dials digits shown on receiver display.

- Call is connected to pager.

For paging externally the following applies:

1. Pagee dials digits shown on receiver display.

- Pagee is connected to the external pager.

##### Bleeper

1. Pagee dials selected digit for answer of paging call.
2. Pagee dials own directory number.

If pager has not gone on-hook, he/she receives a tone burst, whereafter speech connection is established.

If the pager has gone on-hook, he/she will be rung as for a normal incoming call.

#### Diversion to paging function

An extension user can connect himself to the paging number via follow-me or diversion procedure.

For diversion, the call number is inserted as divertee position.

Procedure for follow me:

1. Dial *21* (call number) #.

#### Mode digits

If the paging equipment accepts mode digits for different types of paging, these digits can be sent by ASB 150 02.

If the pager wishes to select the mode digit her-/himself, the call must be made using the number for alternative paging.

See below.

#### Speech possibility

Some paging units allow a spoken message to be sent to the pagee. If paging with speech possibility is utilised, this is indicated by the mode digit.

The time allowed for a spoken message is limited, as the paging channel is occupied during this period. The permitted time is stated via command.

#### Alternative paging

By dialling the digit for alternative paging, the pager can her-/himself choose between two types of paging:

- Display message = mode digit 5
- Loudspeaker paging = mode digit 6

1. Call code * Mode digit * Paged extension * (message if any) #.

The display shows for example:

“11*6*202*12345#”

## Capacity

A maximum of 250 paging numbers are permitted.

Of these numbers up to 50 can be temporary numbers utilised for example by visitors.

The maximum permitted number of unanswered meet-me calls is 25.

The number of concurrently ongoing paging calls in the system is dependent on the number of connected paging channels.

Each paging channel in the paging equipment requires an analogue trunk in ASB 150 02.

## Limitations

Paging is possible in one paging sector only.

Each extension can make one paging call at a time.

If there is no free paging channel congestion tone will be received.

## Programming

### Programming a selected trunk line

The trunk line or trunk lines selected for connection to the paging facility needs to be programmed for this. See also Trunk (486/155 34-ASB 150 02 Uen).

If several lines are connected these are placed in one route. See also Route Selection (444/155 34-ASB 150 02 Uen).
