!GCIPHER = <setting>

!GCIPHER?

Supporting modems:

•All

Enables / disables ciphering and integrity settings

To register onto a network with WCDMA service, the modem’s ciphering and

integrity settings must be enabled or disabled to match the network settings.

Most carriers enable both ciphering and integrity.

When testing the modem, you may be using a SIM that has different codes

for ciphering and integrity than those used by the test system. In this case,

you may need to disable ciphering and integrity checking to use the test

system.

Usage:

•AT!GCIPHER=<setting> sets the ciphering and integrity settings.

•AT!GCIPHER? reports the current ciphering and integrity settings

(0=disabled, 1=enabled).

Parameters:

<setting> (enable / disable ciphering and integrity):

•0 = ciphering disabled; integrity disabled

•1 = ciphering enabled; integrity disabled

•2 = ciphering enabled; integrity enabled

•3 = ciphering disabled; integrity enabled

!GETBAND?

Supporting modems:

•All

Returns the current active band

This command returns the active band currently being used by the modem.

Usage:

•AT!GETBAND? returns a description of the current active band, or returns

an error message.

Note: Due to stack implementation requirements, !GETBAND reports W800

for both W800 and W850.

!GETRAT?

Supporting modems:

•All

Returns the current active radio access technology (RAT)

This command returns the RAT currently being used by the modem.

Usage:

•AT!GETRAT? returns a description of the current RAT, or returns an error

message.

Queries / sets SMS retry period and interval

This command is used to configure the SMS retry period and interval for MO-

SMS.

Usage:

•AT!SMSRETRY? returns the current <period> and <interval> settings.

•AT!SMSRETRY=? reports the format used for AT!SMSRETRY.

•AT!SMSRETRY=<period>, <interval> sets the retry period and retry

interval

Parameters:

<period> (Number of seconds allowed for MO-SMS retry attempts):

•0–255

<interval> (Number of seconds to wait between MO-SMS retry attempts):

•0–255

Note: If <interval> is greater than <period>, a single retry attempt is made.

Note: <interval> ignores the time spent actually performing a retry attempt. If

<interval> = 5, attempts are made at elapsedTime = 0, 5, 10, etc. until an

attempt is successful or <period> - elapsedTime < <interval>.

Example 1:

Assume a retry attempt takes 2 seconds.

If <period> = 1 and <interval> = 8, and no attempts are successful:

•time = 0: Retry attempt fails at time = 2. No more attempts are made

because <period> has expired.

Example 2:

Assume a retry attempt takes 2 seconds.

If <period> = 3 and <interval> = 5, and no attempts are successful:

•time = 0: Retry attempt fails at time = 2. No more attempts are made

because <period> will expire before the <interval> passes.

Example 3:

Assume a retry attempt takes 2 seconds.

If <period> = 14 and <interval> = 5, and no attempts are successful:

•time = 0: Retry attempt fails at time = 2; next attempt will begin at time=5

(the <interval> counts from the beginning of the previous attempt)

•time = 5: Retry attempt fails at time = 7; next attempt will begin at time=10

•time = 10: retry attempt fails at time = 12; No more attempts will be made

because the <period> will expire before another <interval> of 5 seconds

can pass.

Displays / clears 27.010 statistics

TS 27.010 is a standard that defines a multiplexing protocol between a

mobile station and a terminal. This standard is supported on the modem

and AT!MXSTATS is used to display statistics related to that protocol for

debugging purposes.

Usage:

•AT!MXSTATS=0 clears the statistics.

•AT!MXSTATS? reports the statistics.

The command AT!MXSTATS? returns these statistics:

•Sessions Started

•Sessions Ended

•SABM (Tx/Rx)

•DISC (Tx/Rx)

•UA (Tx/Rx)

•DM (Tx/Rx)

•UIH (Tx/Rx)

•T1 expiry

•N1 count

•N2 count

•Bad Frame (addr)

•Bad Frame (ctl)

•Bad Frame (len)

•Bad Frame (F9)

•Bad Frame (fcs)

Command Description

!NVBACKUP

=<category>

Supporting modems:

•All

Backs up items stored in non-volatile memory

This command creates a backup that is stored in the modem’s flash memory.

Parameters:

<category> (specify items to back up):

•0 = Factory items (RF calibration data) — Used only at the factory (only

needs to be done once for the lifetime of the device)

•1 = OEM items (PRI customizations) — Used only by the OEM when loading

a new PRI configuration (only needs to be done once for the lifetime of the

device)

•2 = User items (customizations, including those made by Watcher or other

host applications) — This is the only backup option that should be employed

by users. Use this command before doing a firmware update. If the

modem’s file system is reinitialized for some reason during the update, the

customizations would then be automatically restored using from the backed-

up information.

The command returns:

•NV Items saved

•NV Items skipped

The ‘items skipped’ represent memory to which nothing has been written.
