I have to send SMS text in binary encoded format using the SMPP SUBMIT_SM packet setting data_coding field of SMPP SUBMIT_SM to "2". Can tell me does NowSMS supports Binary encoding? If yes, then which is algorithm is used for that?

If you submit binary SMS to NowSMS, and it is routed to an SMPP connection, NowSMS normally uses a data_coding value of 4. (NowSMS actually will convert a data_coding value of 2 to 4. Both values mean binary encoding in SMPP, but only 4 means binary encoding in GSM environments. That is why NowSMS has historically converted 2 to 4 for binary messages.)

That said, we have encountered some SMPP service providers that understand binary messages with a data_coding value of 2, but do not understand a data_coding of 4.

There is a configuration setting in NowSMS 2009.03.17 or later that is available to force NowSMS to use a binary DCS value of 2.

To activate this setting, edit SMSGW.INI, and locate the [SMPP - server:port] section that defines settings for your SMPP connection. Under this section header add BinaryDCS=2

More details:

quote:

* SMPP: In SMPP environments, generic 8 bit-binary messages can be encoded with a data_coding value of either 2 or 4. NowSMS always uses a data_coding value of 4 (and converts 2 to 4, as they mean the same thing in the SMPP specification), because 4 is a valid data_coding value for a binary message sent over the air in a GSM environment, while 2 is not a valid value for an actual over the air message. To address an issue for a service provider that will only accept binary messages with a data_coding value of 2, there is a new configuration setting to remap the data_coding value from 4 to 2 for SMPP connections. To apply this setting for messages being submitted to a particular SMSC, edit SMSGW.INI, and under the SMSC specific section (e.g., [SMPP - server:port]), add BinaryDCS=2. To apply this setting for all SMPP client accounts (e.g., "SMS Users"), add BinaryDCS=2 under a section header of [SMPP] (this section may or may not already exist, if it does not, it should be added). (Note: There is also a BinaryDCS=## setting available under the [SMSGW] section of SMSGW.INI, however this setting has a slightly different purpose. The other BinaryDCS=## setting sets the data_coding value to be used for any WAP Push messages generated by NowSMS. By default it is F5, however some SMSCs require a value of 4 instead.) http://support.nowsms.com/discus/messages/1/24851.html
