SMPP Connector Reference

The following operations allow you to work with the SMPP Connector. Click an operation name to see parameter details and samples on how to use it.

Create SMSC Connection

To use the SMPP connector, need to have a SMSC connection. To create a SMSC connection add the <SMPP.init> element as a local entry configuration before carrying out any other SMPP operation. This is used to bind with the SMSC (Short Message service center). Once a connection is defined this can be reused among other SMPP operators.

init

The init operation appends content to an existing file in a specified location.

Parameter Name Description Required
host IP address of the SMSC. Yes
port Port to access the SMSC. Yes
systemId username to access the SMSC. Yes
password password to access the SMSC. Yes
enquireLinkTimer Used to check the connectivity between the SMPP connector and SMSC. Optional
transactionTimer Time elapsed between SMPP connector request and corresponding response. Optional
systemType It is used to categorize the type of ESME that is binding to the SMSC. Examples include “CP” (Content providers), “VMS” (voice mail system) and “OTA” (over-the-air activation system). Optional
addressTon Indicates Type of Number of the ESME address. Optional
addressNpi Numbering Plan Indicator for ESME address. Optional
