Did you mean under "max-submit-requests" max-pending-submits in kannel ?
max-pending-submits number Optional the maximum number of outstanding (i.e. acknowledged) SMPP operations between an ESME and SMSC. This number is not specified explicitly in the SMPP Protocol Specification and will be governed by the SMPP implementation on the SMSC. As a guideline it is recommended that no more than 10 (default) SMPP messages are outstanding at any time. Thanks.
