About pck doubt?

Question

i am studying pck in the following link.
<a href="http://help.sap.com/saphelp_nw04/helpdata/en/e1/091640a991c742e10000000a1550b0/content.htm">pck-xi adapter</a>
i don't understand the following words:
If messages are sent from the Integration Server to the PCK, you must create a sender XI adapter in the PCK.
since are from the integration Server to the PCK, PCK is a receiver.
why must create sender xi adapter in the pck.?why,that is why?
i can not understand!
i think:
if it is sender xi adapter,why is it in the pck instead of  in the integration server as the integration server is a sender in fact.vice versa.
my understanding was wrong?
who can explain it clealy?thanks!

the PCK is used,if you want to exchange Messages from or to XI. That means for that,you need on the sender or receiver Side a XI System. The one way is,that a XI sends the Native XML SOAP Messages via XI Adapter to the PCK.Then the message can be converted in some other formats,because the PCK has its own Adapter Engine. But there is no IDOC adapter.
The second way ist,that for example you pick up XML Files with the PCK and transfer it to an XI system in the Native XML Format. With the PCK you can't do a File-to-File Transfer.
The PCK is a standalone Application,which has its own Monitoring,Configuration and User Management.Instead of that, a decentral Adapter Engine is directly connected to an XI System and is configured centrally in the XI System
PCK is a mini version of XI. It is used by smaller business partner (who cannot afford to install a full blown version XI) to exchange XI messages with large companies (having an XI installation).
PCK has its own local Adapter engine.
