5. The General Packet Radio Services GPRS standard permits DATA transfers in a completely different way with respect to previous point to point communications made with Circuit Switch Data CSD GSM modems In CSD operations the modem establishes a connection with the other party another modem in such a way that all the Network devices in between are transparent to the data exchanged simulating a real point to point connection just as if the other party is directly connected with the controlling application of the modem The other party can be either an Internet Service Provider ISP or a private server but in any case the arrival point must have a modem to connect to Landline ISDN or GSM CSD The connection establishment procedure defines a particular path where all the information exchanged between the two peers flows and this path is reserved for exclusive use of these 2 peers for all the time the connection is active This approach has the drawbacks of a long time to set up the link between the two peers up to a minute and a time counting bill which proceeds even if no data is exchanged because the path resources are reserved anyway furthermore the speed of the data transfer is limited to 14400 bps An example of this kind of operation is shown in the following picture where the point to point connection is between the two peers as if all the devices inside the dashed line are not present a Fi pow a Network inter
