Terms and definitions in messaging
Multichannel messaging service is based on a variety of telecommunication and Internet technologies. In the description of services, we often use abbreviations that may not always be known to you. Here we have compiled a glossary of terms and definitions used in the industry.
By the way, you can create account and send SMS to your customers via Dashboard, plugin or API integration.
PDU
Stands for “Protocol Data Unit”. A PDU is a specific block of information transferred over a network. It is often used in reference to the OSI model, since it describes the different types of data that are transferred from each layer.
As per the SMPP specification, each PDU has a mandatory header section that is the same for each PDU transmitted between ESME and SMSC.
