Hi daniel,
You can get the error code from class to find out what is the problem , and don't forget to put SMPP version in your class.
$pdu = pack("a{$system_id_len}a{$smpppassword_len}a{$system_type_len}CCCa1", $system_id, $smpppassword, $system_type, 0x34, 1, 1, "");
that is smpp version34
make sure you have all configuration as per request by SMPP server (SMSC)
