# Soft Modem Build Script
The OAI EPC is developed in a distinct project with it's own [documentation](https://github.com/OPENAIRINTERFACE/openair-epc-fed/wiki) , it is not described here.

Running the [build_oai](../cmake_targets/build_oai) script also generates some utilities required to build and/or run the oai softmodem binaries:
- `con2uedata`: a binary used to build the UE data from a configuration file. The created file emulates the sim card of a 3GPP compliant phone.
- `conf2uedata`: a binary used to build the UE data from a configuration file. The created file emulates the sim card of a 3GPP compliant phone.
- `nvram`: a binary used to build UE (IMEI...) and EMM (IMSI, registered PLMN) non volatile data.
- `rb_tool`: radio bearer utility
- `genids` T Tracer utility, used at build time to generate T_IDs.h include file. This binary is located in the [T Tracer source file directory](../common/utils/T) .

## Legacy 1 Bench
**Purpose** : FDD Band 7 and Band 13, LTE-M
**Note** : Legacy1 and Legacy2 are duplicated so that they can run in parallel, thus avoiding a CI bottleneck
**Note** : Faraday Cages 1 and 2 are physically the same cage

## Legacy 2 Bench
**Purpose** : TDD Band 40, TM2 2xTX 2xRX
**Note** : CN can run in a container, could also run on Massive

## Next Bench for DEV
**Note** : Benetel CI can also run on this bench at night
