Room Recovery (Model 90)
These messages are used by the PMS to update the database in the Model 90
version after a failure recovery. These messages will usually only be sent if
requested by the NEAX using the Nop Test Recover Answer message. However,
the PMS may, if necessary, initiate a recovery with a direct request from the
NEAX.
Before any recovery messages can be sent, the PMS must first send a Recovery
Start Report message. After all information about rooms has been sent by recovery
messages, a Recovery End Report message must be sent. Both of these messages
are defined in the Data Link Maintenance section.
• Room Data Report -- Once Recovery has been requested by the NEAX, the
PMS uses this message to report the data for each room.
• Guest Room Secretary Telephone -- This message is used to recover data for a
secretary telephone.
• Connecting Room -- If any rooms are connecting, this message is used to
establish the relationship.
• Message Status Report -- This reports the status of the Message Waiting Lamp.
• Wake Up -- Any wake up data is reported by this message.
Direct Data Entry (Model 90)
These messages are used to send numeric information from the NEAX to the PMS.
An employee provides this information by entering an access code at a guest room
telephone. Then the NEAX captures all numeric input following the access code
and sends the digits to the PMS.
The NEAX expects to receive a response to this message within 30 seconds. If no
response is sent, or a Negative Answer is received, a reorder tone will be heard. If
a Positive Answer is received, the NEAX will recognize that the information has
been entered successfully and the service set tone will be heard.
• Direct Data Entry -- This message is sent by the NEAX and contains the
numeric information entered at the guest room telephone.
• Direct Data Entry Negative Answer -- This message is sent by the PMS to notify
the NEAX that the numeric data sent from the specified guest room telephone
has been rejected.
• Direct Data Entry Positive Answer -- This message is sent by the PMS to notify
the NEAX that the numeric data sent from the specified guest room telephone
has been accepted.
