There's no "using udh instead of the DCS". This don't make sense. One is the
User
Data Header, other is Data Coding Scheme. You can't have Data coding scheme
in User Data Header, nor Udh in DCS, neither text message in A-Number
neither
PID in text field....

Every field has a meaning and expected values.

Except.....

UCP at least from 3.5 says:
(EMI_UCP_Specification_40.pdf: page 38)
"DCs    Deprecated"
"MCLs    Message Class. Shall be supplied when MT=4 and Xser "GSM DCS
information" is not supplied."

Page 39
"If the MCLs field is also specified, the GSM DCS information field in the
XSER field

overrules the MCLs field."

Do you have some older version of UCP that still requires DCS in deprecated
DCs
and MCLs fields ?

(snip text comparing potatoes with harddisks)

You probably want the old behaviour....

Try this patch and see if it works:
