Extension Connection
Each message group will be described briefly in the following sections.
The NEAX equates rooms with extensions, one extension per room. The exception
to this is the suite room feature. When this feature is activated in the NEAX, a
primary extension represents a group of extensions in one or more rooms. For a
suite room, the PMS should reference only the primary extension in its messages
to the NEAX. All associated extensions will inherit the attributes of the primary
extension and should effectively be ignored by the PMS.

Data Link Maintenance
These are the messages used by the PMS and NEAX to maintain communication.
The PMS must regularly send Nop Test messages with an interval of no more than
60 seconds, and no less than 500 milliseconds, between each message. The NEAX
will immediately respond with either a Nop Test Normal Answer, under normal
conditions, or a Nop Test Recover Answer, if a database recovery for the NEAX is
needed.
