# Group Paging

Group paging is an LRS extension to POCSAG that allows pages to be sent simultaneously to a subset of the entire system. 4-line alphapagers will indicate a page was a group page on the page summary screen. If the group has not been named, then the group number will be shown:

![178](https://files.readme.io/QwrHA1HQQObyxvpS3ZFv_Alphapager%20Protocol-Revision%2012_img_1.jpg "Alphapager Protocol-Revision 12_img_1.jpg")

If the group has was named at programming time, then the name will be shown:

![178](https://files.readme.io/UJnY7poIQ9SjmL0ExVZQ_Alphapager%20Protocol-Revision%2012_img_2.jpg "Alphapager Protocol-Revision 12_img_2.jpg")

## Group Numbers

Group numbers are 2-decimal digits. Valid group numbers are `0` through `98`. `99` is reserved to indicate a disabled group slot.

## Transmitting Group Pages

Group pages are always sent to the system capcode of the pager. The start of a group page takes the following form:

```c
[##]
```

where `##` is a 2 digit decimal group number, left padded with zeroes (`0`) if necessary. The message to display is comes after the `]`.

## Examples

The following example sends "Customer in showroom" to all pagers in group 3.

```c
[03]Customer in showroom
```

The following example sends "Register help needed" to all pagers in group `29`.

```c
[29]Register help needed
```
