A operação de BIND é a operação de tentativa de abertura do canal SMPP entre uma ESME e um SMSC. Conforme dito anteriormente, uma ESME pode fazer um bind_transmitter, bind_receiver ou bind_transceiver. Caso a ESME tente conectar-se com um bind_transceiver em um SMSC não suporte esta operação, este deve retornar uma mensagem de resposta contendo o erro ”Invalid Command ID” e a ESME deverá tentar conectar-se novamente, desta vez com um bind_transmitter ou bind_receiver ou um par bind_transmitter, bind_receiver. Caso a ESME tente conectar-se com um bind_transmitter ou bind_receiver em um SMSC não suporte esta operação, este deve retornar uma mensagem de resposta contendo o erro ”Invalid Command ID” e a ESME deverá tentar conectar-se novamente, desta vez com um bind_transceiver.
Uma ESME conectada como uma transmitter está autorizada a enviar mensagens a um SMSC e receber as respostas SMPP correspondentes. Uma ESME indica que não deseja receber mensagens originadas de outra SME (i.e. terminais móveis), conectando-se como transmitter. Verifique na tabela 1 quais são as operações permitidas a uma ESME conectada como transmitter.

Tabela 6 - PDU do BIND_TRANSMITTER
a.
There is no specific requirement on how the sequence_number
should be set. However, it is recommended that the sequence number be a
monotonically increasing number.
b.
The recommended use of system_id is
to identify the binding entity, e.g., “InternetGW” in the case of an
Internet Gateway or ‘VMS’ for a Voice Mail System.
c.
The password is used for
authentication to secure SMSC access. The ESME may set the password to NULL to
gain insecure access (if allowed by SMSC administration).
d.
The system_type
(optional) may be used to categorise the system, e.g., “EMAIL”,
“WWW”, etc.
