SMPP Connection Mode

The SMPP connection mode is to be specified by an SMPP-client when attempting to authenticate at SMPP-server i.e. when performing bind. It defines basic data exchange rule between client and server.

There are 3 SMPP connection modes available:

  • Transmitter - allows only to send SMPP commands to the SMSC and receive corresponding SMPP responses from the SMSC.
  • Receiver - allows only to receive SMPP commands from SMSC and send corresponding SMPP responses.
  • Transceiver - allows to send and receive SMPP commands in SMSC.

Example of specifying the connection type by SMPP-client.
