This section describes the standards compliance for the communication services for Parlay X 2.:
The Parlay X 2.1 interface complies to ETSI ES 202 391-4 V1.2.1 (2006-12) Open Service Access (OSA); Parlay X Web Services; Part 4: Short Messaging (Parlay X 2).
See http://portal.etsi.org/docbox/TISPAN/Open/OSA/ParlayX21.html for links to the specification.
The SMPP v3.4 plug-in for Parlay X 2.1 Short Messaging and for the Extended Web Services (Binary SMS) acts as an External Short Message Entity (ESME) that connects to an SMSC over TCP/IP.
The plug-in instance binds itself to the SMSC either as ESME Transmitter and an ESME Receiver or as an ESME Transceiver.
The bindings occurs when the plug-in transitions from state inactive to active. It will not reach state active until it has bound. The plug-in unbinds itself prior to becoming inactive.
When an application sends an SMS with one recipient submit_sm PDU is used and when sending an SMS with 2 or more recipients submit_sm_multi is used.
For application-initiated requests, the plug-in supports segmented SMSs using either 7-, 8-, or 16 bit data coding. The maximum length of an SMS segment is:
For network-triggered requests, the plug-in supports segmented SMSs in the same way as for application-initiated request if the SMPP parameter short_message contains the user data. If short_message is empty the parameter message_payload, which can contain up to 64KB of data, is used.
For network-triggered requests, the SMS is propagated to the application via the Parlay X Short Messaging interface if the SMPP parameter data_coding equals 0x00, 0x01, 0x03, 0x05, 0x06, 0x07, 0x08, 0x0A, 0x0D, or 0x0E. In other cases, the SMS is forwarded to the application via the Binary SMS interface.
The plug-in complies to Short Message Peer to Peer, Protocol Specification v3.4, Document Version:- 12-Oct-1999 Issue 1.2.
