Airlink X EV-DO manual AT Commands CDMA/EV-DO, +CTA=n, $QCMIP=n, ~NAMLCK=nnnnnn

AT Commands: CDMA/EV-DO

CDMA/EV-DO

This group includes commands specific to CDMA/1x and EV-DO.

FIGURE 1. CDMA/EV-DO

+CTA=n

Inactivity timer, in seconds.

n=seconds (maximum 20 seconds)

n=0 : Allows the Verizon network to determine the inactivy timer.

Typical network settings cause a link to go dormant after 10 to 20 seconds of inactivity, no packets transmitted or received. This time can be shortened to release the physical RF link sooner when the application only transmits short bursts.

$QCMIP=n

Mobile IP (MIP) Preferences.

n=0 : Disabled, SIP only

n=1 : MIP preferred

n=2 : MIP only

On a Mobile IP network, a device connects to the network using PPP. During the negotiation process the Raven X is NOT required to present a username and password to authenticate because the authentication parameters are stored in the modem itself.

Note: Your account with Verizon may not support Mobile IP.

~NAMLCK=nnnnnn

The NAMLCK is the modem's 6-digit OTSL (One Time Subsidy Lock), MSL (Master Subsidy Lock), or SPC (Service Provisioning Code). Verizon will provide the unlock code.

nnnnnn=6 digit unlock code

If the number is accepted by the modem, the OK result code is returned. If the number is rejected, the ERROR result is returned. If three successive Errors are returned, the modem must be reset to allow any further attempts.
