The dormant state is an important advantage of the packet data service offering since it allows the AT's natural state to be dormancy where the AT does not utilize any radio resources and has minimal power consumption. The packet data connection can be reactivated from dormancy to the connected state without having to re-establish PPP link again when an IP packet arrives from the test set or any host on the network destined to the AT (for example, file transfer over FTP, ping the AT from the test set, etc.). This makes the connection faster.
The dormant state is a non-transitory state (see Packet Data Connection Processing States Lifecycle ).
To query the state of the data connection, see Data Connection State Synchronization .

Call Control 1 of 3menu) or sends CALL:FUNCtion:DATA:DORMant to the test set (see AN Initiated Connection Close to Dormant State ), or
If for some reason the PPP connection can not be maintained, the test set will transition to Session Open State .
