t3395-timeout secs
Defines the maximum amount of time for retransmission of ‘deactivate request’ messages.
secs
: Must be an integer from 1 to 60.
Default: 8
t3396
This keyword enables the session management (SM) T3396 back-off timer for the 2G service. When the
SGSN is confronted by a situation involving congestion, the SGSN can assign the back-off timer value to the
UEs and reques the UEs not to access the network for a given period of time.

min minimum
: Enter an integer from 1 to 15 to identify the minimum number of minutes that the timer will
run; default is 15 minutes.
max maximum
: Enter an integer from 1 to 30 to identify the maximum number of minutes the timer can run;
default is 30 minutes.
cause cause_code
: Enter an integer from 1 to 255 to identify the appropriate rejection cause code. The
default is 26. During congestion, the configured value is ignored and 26 is sent.
During congestion, the SGSN randomly chooses a T3396 value from the configured range and sends
that timer value to the UE in the Reject message with the cause code #26.
The command can be repeated to define a maximum of 16 cause codes.
trim-trailing-spaces-in-apn
Enables SGSN to strip off any trailing space(s) in requested APN.
If a requested APN in an Activate PDP Context Request has any trailing spaces, then those trailing spaces
will be removed and the length field will be updated.

will be removed and the length field will be updated.
Usage
Repeat this command with different keywords (parameters) to configure the SM (session management) as
needed for this GPRS service. Keywords can be used to optimize signaling between the MS and the SGSN to
reduce the impact on the radio resources.
