6. Network Implementation


6.1 Network Error Codes

The SMPP PDU, query_sm_resp contains an "error_code" field. The range of values this field may have, depends entirely on the underlying telecommunications network.


6.2 Maximum Message Length

Each network variation is limited to some fixed maximum length. This may be further affected by data coding scheme.

The SMSC, depending on configuration, may reject or truncate messages that exceed the network allowed maximum.
