Figure 1: GXP2130/GXP2140/GXP2160 XML API via HTTP 
 
 
Two types of XML API architecture are introduced below, depending on whether the transaction is via LAN 
or Internet. 
 
1.  A  transaction  in  the  LAN  may  exchange  information  in  the  following  manner.  The 
GXP2130/GXP2140/GXP2160  sends  a request  to the  web server via  HTTP/TFTP and  waits for  a 
response with the XML contents. The web server will handle the request and communicate with the 
application server to get the information for the XML phone book content display. The following figure 
shows downloading XML phone book file via HTTP within a LAN.

2.  If the above Web Server accesses Internet, it could interact with outside web server and respond with 
real-time content to the GXP2130/GXP2140/GXP2160.
