# DMR contact extension

This extensions allows to specify some DMR contact attributes for devices running the OpenGD77 firmware. This extension is only applicable to DMR (digital) contacts.

##

    contacts:
      - dmr:
        name: Example contact
        number: 1234567
        openGD77:
          timeSlotOverride: TS1

The OpenGD77 contact extension is a mapping named openGD77. It contains the device specific settings for that DMR contact.

For now, there is only one attribute allowing to override the time slot of a channel whenever this contact is selected as the destination contact for that channel.

## Channel extension fields

timeSlotOverride

- OpenGD77 allows to override the time slot settings for each channel on the bases of the selected transmit contact. If the contact has a time slot override set, this time slot is used instead of the channel time slot. This attribute is either None, TS1 or TS2. If None is set, the channel time slot will not be overridden.
