Information in this document applies to any platform.
Messaging Manager can not send SMS (Short Message Service) when using its SMPP (Short Message Peer-to-Peer) adapter configured with a GSM7Bit alphabet.
THe following debug output can be seen in the /IN/service_packages/XMS/tmp/xmsTrigger.log file showing the GSM7Bit is not supported so uses the GSM8Bit alphabet instead.
The Messaging Manager Technical Guide - Chapter 3, Configuring the SMPP Adapter - states that GSM7Bit alphabet is allowed though.
Syntax: alphabet = "<charset>"
Description: Character set of the desired alphabet.
NCC documentation can be found by following Doc ID 1341844.1 - How to Download Oracle Communications Network Charging and Control (OCNCC/NCC) Documentation.
Messaging Manager documentation describes how to set the alphabet, depending on required message class (Store or Flash). Example requirements may be:
- DCS = 0 having message class 0 (Store SMS) should have 8bit coding.
- DCS = F0 having message class 1 (Flash SMS) should have 7bit coding.
For more details, refer to Data Coding Scheme (DCS) section and Message Classes section of Global System for Mobile (GSM).
