Local Area Service
This mode, also called Fallback Mode, allows more than one
terminal from the same site to communicate when the link
between the site and network central controller fails. Entering
and exiting Local Area Service (that is, returning to System
Wide Services) is done automatically.
Entering Local Area Service
When the MTP850 receives a Local Area Service indication
from the system, the following occurs:
• The MTP850 sounds a tone.
• The display shows the “Local Area Service” message.
• Display icons and soft keys turn green.
• Any call in progress is dropped upon entering Local Area
Service mode.
If configured by your Service Provider, this message/alert is
periodically repeated to remind you that the MTP850 is still
operating in Local Area Service mode.
The following features are available while the MTP850 is in
Local Area Service:
• Registration
• Attachment
• Group Call
• Emergency Call
• Emergency Alarm
Exiting Local Area Service
When the link with the central network controller is re-
established, the MTP850 exits Local Area Service and the
following occurs:

This mode can be disabled by your Service Provider.
