This page is valid on the following branches:
- `develop` starting from tag `2020.w48`
# 1. Building the ITTI simulator.
The ITTI simulator is available directly from the standard build.
```bash
$ source oaienv
$ cd cmake_targets
$ sudo ./build_oai -x -w None -c -ittiSIM
```
# 2. Running the ITTI simulator.
The ITTI simulator establishes ITTI-threaded communication between the gNB RRC task and the UE RRC task.
This allows to test the sequence of NGAP/RRC/NAS messages.
The main limitations are:
- NAS is a simple stub that just sends and receives messages
- only initial Attach sequence
## 2.1. Starting the ITTI simulator
The ITTI simulator is able to run with a connected 5GC or without any.
The develop branch tag `2020.w48` only works RRC without 5GC connection.
```bash
$ sudo -E ./ran_build/build/nr-ittisim -O gnb.conf
```
