Hi Ben

Thanks for replying.  dest_subaddress is an SMPP (3.4) optional parameter. 
In the specification, it's defined as:

"
Tag                  | Value    | Wireless Network Technology
dest_subaddress | 0x0203  | CDMA, TDMA
"

"The dest_subaddress parameter specifies a subaddress associated with the
destination of the message".

In this case, our supplier uses it to pass along a code that represents the
originating network of the MO.  An example:
