Chapter 6 – +C Prefix Commands

CDMA 1xEV-D0 AT Commands Reference Guide (Document S000482B) 36

+CTA= Packet Data Inactivity Timer

Syntax: AT+CTA=<n> (Sets the Packet Data Inactivity Timer)

AT+CTA? (Reads the value)

Description: This timer determines when (or if) the modem will use dormant mode on the network. If a

timer value is set, the modem releases the radio resource if there is no activity (RLP data

frames) on the connection between the modem and the network for the specified period.

The modem maintains the PPP session with the local host, and the network retains the

PPP session at its end, only the intervening “physical link” layer is dropped. The modem

restores the link when traffic resumes.

Each unit represents 1 second.

Value Meaning

0 Disables the timer (default)

1–255 Indicates timer value in seconds.

Note: When set to 0, the network governs the dormant mode timing.

See also +CQD (Command State Inactivity Timer).

+CXT= Cellular Extension

Syntax: AT+CXT=<n> (Enables/disables the passing of unrecognized AT commands)

AT+ CXT? (Reads the value)

Description: Enables and disables the passing of unrecognized AT commands to the IWF. If disabled,

the modem replies with ERROR to unrecognized commands. If enabled, the modem

opens the transport layer airlink and enters pass through state.

Use H0 (on-hook) to close the airlink.

Value Meaning

0 Do not pass unrecognized commands. (Default)

1–255 Open a transport layer connection and pass the unrecognized command to

the IWF.
