This group includes commands specific to CDMA.
+CTA=n
Inactivity timer, in seconds.

Typical network settings cause a link to go dormant after 10 to 20 seconds of inactivity, no

sooner when the application only transmits short bursts.

On a Mobile IP network, a device connects to the network using PPP. During the negotiation
