HIS Troubleshooting Guide

Introduction

In order to integrate reliably between the HIS PMS system and the NuPoint Voice system, the following protocol has been developed. The protocol contains three layers; physical, link, and message. This protocol conforms to the "HIS Standard Communications Protocol for Full Duplex Operations" fully with the following stipulations:

Physical Layer

Electrical Interface: EIA RS232C - Type D electrical standard compatibility. Connection is via a DB25-pin male connector.

Signal Form: EIA RS404.

Interface Distance: Maximum 50 feet. Interface unit to Interface Processing Unit direct connection. Distances exceeding 50 feet require a line driver.

Operation Mode: Full duplex.

Link Layer

Appearance:

Data Rate: 2400 Baud Asynchronous

Byte Framing: 10 bits, (1 start, 7 data, 1 parity, 1 stop), even parity.

Message Layer

There are six messages defined for the protocol as follows:

  • Message number 1 is RESYNC.

  • Message number 2 is ROOM OCCUPIED.

  • Message number 3 is ROOM VACANT.

  • Message number 4 is MESSAGE WAITING STATUS.

  • Message number 5 is BAD MAILBOX ADDRESS.

  • Message number 6 is SEND MESSAGE WAITING STATUS.

Mailbox Re-synchronization

With the HIS PMS integration, an additional menu choice (G) has been added to the System Maintenance Menu to allow the system administrator to re-synchronize the state of all the mailboxes being supported by the PMS.

Message Waiting

The HIS PMS Integration supports message waiting notification through the PMS system. A message waiting type has been added to the system called "HIS PMS." See Assign Message Waiting Type to a Mailbox.

7.0 Diagnostic Information

See the Appendix for detailed diagnostic information available through the error log file, the CDR file and the system console.
