Notes:
Under LTE Policy, the maximum number of cause code groups supported is 4. Note that this means that the total
number of cause code groups available across all the services (SGSN+GPRS+MME) is 4.
group_name

ranap
:
Accesses the RANAP Cause Code Group configuration mode for the commands to define the cause
codes for the 3G service
Presents a prompt similar to the following:

cause
: A maximum of 16 RANAP protocol cause codes can be defined per group. This command, in
the new RANAP Cause Code Group configuration mode, enables the operator to define multiple
