Extension Connection
These messages are used to associate extensions. This association will be either in 
the form of a Boss/Secretary or of a Master/Secondary. In either case, both of the 
rooms to be connected must be checked in. There may only be one Secretary for 
each Boss, but a Secretary may be assigned to multiple Bosses. A Master and 
Secondary may only be assigned on a one to one basis.
The Extension Connection messages use the following Function Codes:
62-1 -- Guest Room Secretary Telephone (PMS)
62-2 -- Guest Room Secretary Telephone (NEAX)
62-3 -- Connecting Room Set
62-4 -- Connecting Room Cancel

Property Management System - Communication Interface Glossary
Chapter 6 Glossary
BCC Block Check Code. Computed by an exclusive OR of the 
message from the SA field to the ETX character, inclusive. 
This is used to assist in error control.
EI Entry Index. Always ‘L’ for the PMS interface.
ETX End of Text. Special control character used to denote the end 
of a message block. Always 03H.
FC Function Code. Identifies a specific message within a feature 
code. The combination of feature code and function code 
uniquely identifies each message. See Appendix C for a list of 
codes.
FTC Feature Code. Identifies a set of related messages. See 
Appendix B for a list of codes.
MSC Message Counter. Specifies the length of the significant data 
in a message. The count begins with the FTC field and ends at 
the last character of the body (prior to the ETX character). The 
count includes the MSC field, which is always two characters.
MWL Message Waiting Lamp.
NEAX The NEAX2400 IMS system. It is a private branch exchange, 
which is a digital voice and data communication system for 
the office.
PMS Property Management System. A set of software and 
hardware which manages a hotel’s assets.
SA System Address. Always ‘1’ for the PMS interface.
STX Start of Text. Special control character used to denote the start 
of a message block. Always 02H.
Suite  Room This is an optional feature of the NEAX that enables a group 
of extensions to be treated as the same extension in a room. 
Messages refer to all extensions in a suite by means of the 
suite’s primary extension.
UA Unit Address. Always ‘!’ for the PMS interface.
Violation Code This is a special FTC that ranges from 80H to FFH. It 
identifies a message from the PMS that the PBX (or UAP) has 
rejected for some reason. The FTC of the original message, 
subtract 80H from the violation code. The body of the original 
message is unchanged.
