Architecture

The PMS communicates with the NEAX over one or more serial cables. A maximum of three lines can be provided as data links between the NEAX and the PMS.

The three lines are designated as Line 1, Line 2 and Line 3. Line 1 is used for Hotel Processing messages; Line 2 and Line 3 are used for Interactive messages.

Hotel Processing messages, such as Check In, Check Out and Message Waiting Lamp control, have less severe real-time requirements than interactive messages. Line 1 is only utilized for these messages and they will never be sent over Line 2 or Line 3.

Interactive messages are the Direct Data Entry messages and Maid Status Answerback messages. These messages require real-time interaction between the PMS and the NEAX and can therefore be isolated from the Hotel Processing messages. If Line 2 is installed, these messages will be transmitted over that line. If Line 2 and Line 3 are installed, these messages will load share over both lines. If only Line 1 is installed, these messages will be transmitted over Line 1.

The use of Line 1 is mandatory. If only Line 1 is installed, all messages are transmitted over it. Also, if Model 60 is being used, only Line 1 is necessary, as all of the Interactive messages are exclusive to Model 90.

It is very rare for Line 2 or Line 3 to be required. They are only needed if the traffic between the PMS and the NEAX is to be exceptionally heavy. And even the heavy traffic should only require Line 2.

The PMS may communicate with the NEAX through either an asynchronous transmission protocol or a bisynchronous transmission (BSC) protocol.
