Working in the airport IT industry you are always challenged with integration tasks at each airport. Usually you face a heterogeneous landscape of home-brew or taylored solutions and standard software running on anything from mainframe to virtual instances in a private clouds. Using an ESB we can tackle a lot of interfacing work and focus on the data integration part. One interface that you will find on all airports that operate commercial flights, is a link to the SITA network to send and receive IATA Telexes.
It is hard to find any information online, so I summarised the available message types here. Btw, these telex types are often referred to as SITA Telex types, which is not correct, IATA (Air Transport Association) defines the available telex types and SITA is operating the network to distribute the messages between airlines, airports, ATC, groundhandling agents and other relevant members of the airport community.
This list should be almost complete, giving you the type, the description and the AHM (Airport Handling Manual) or RP (Recommended Practice) reference. The AHM that you can purchase from IATA gives you all the syntax and details for most of the available types.

MVT, LDM, PTM, TPM, CPM, PSM, UCM are among the most common telexes from my experience. If you implement a telex interpreter you definitely need to implement these types first.
I am working on an online telex processor, a demo version I will put online soon.
