RE : SMPP 3.3 trouble

Thanks, I just applied it and I have the following log (see below).

I have 2 questions:
- Why is there 2 enquire link, is there one for the transmitter and one
for the receiver?
- The sequence number of the generic_nack seems to refer to the bind
transmitter and bind_receiver. Is it the case? If it is, why does the
SMSC wait for the enquire_link to send the generic_nack. If it is not
the case, what could explain it? (SMSC trouble? ). 

Regards.
